If you are looking for ransomware protection software, here is the conclusion first.
For individuals, Norton 360 is a practical choice because it is easy to build broad protection around it. For small businesses without dedicated IT staff, AppCheck is easy to add on top of existing security software. For mid-sized companies and larger organizations with internal IT staff, a setup that includes EDR in addition to EPP is the most realistic approach.
According to the National Police Agency’s report, “The Situation Surrounding Threats in Cyberspace in 2024”, the number of reported ransomware incidents in Japan rose sharply from 21 cases in the second half of 2020 to 222 cases in 2024.
In IPA’s “Top 10 Information Security Threats 2026”, “damage caused by ransomware attacks” is also ranked as the number one threat for organizations.
This article clearly organizes the following three points.
Types of ransomware protection software and how to choose them Recommended products for individuals and businesses How to judge whether free software or Windows Defender alone is enough In some cases, simply installing software in-house is not enough. It is often best to start by consulting a security company for free.
Why You Need Ransomware Protection Software Right Now
“I know it is dangerous, but I do not know what standard to use when deciding on a countermeasure.” Many people likely feel this way. First, let us organize why protection software is needed now by looking at the trend of domestic incidents and the current reality of ransomware attacks.
Domestic Incident Reports Have Increased More Than Tenfold in Five Years
According to National Police Agency data, the number of reported ransomware incidents affecting companies and organizations increased from 21 cases in the second half of 2020 to 222 cases in 2024.
Even on a half-year basis, the figures were 61 and 85 in 2021, 114 and 116 in 2022, 103 and 94 in 2023, and 114 and 108 in 2024. In addition, the first half of 2025 also remained high at 116 cases.
In IPA’s “Top 10 Information Security Threats 2026”, “damage caused by ransomware attacks” is ranked as the number one threat for organizations, and it has appeared every year for 11 consecutive years since it was first selected in 2016.
Period Number of Reported Incidents Second half of 2020 21 cases First half of 2021 61 cases Second half of 2021 85 cases First half of 2022 114 cases Second half of 2022 116 cases First half of 2023 103 cases Second half of 2023 94 cases First half of 2024 114 cases Second half of 2024 108 cases And importantly, this is not just a problem for large enterprises. According to National Police Agency materials, 2024 included 140 cases involving small and medium-sized businesses, 61 involving large enterprises, and 21 involving other organizations, meaning SMEs accounted for about 63% of the total. In the first half of 2025, SMEs accounted for 77 cases, or roughly two-thirds of the total. The idea that “we are small, so we are probably not a priority target” does not match the current reality.
“We Have Backups, So We Are Safe” Is an Outdated Assumption
Backups are still extremely important. However, this is no longer an era where you can confidently say, “We are safe because we have backups.” In CISA’s StopRansomware Guide, it is explicitly stated that modern ransomware often searches for accessible backups and attempts to delete or encrypt them. For that reason, backups should be kept offline or immutable and should be tested regularly through restoration drills.
In other words, the key point is not just whether backups exist, but whether they are maintained in a form that attackers cannot reach. And even paying the ransom does not guarantee recovery. The FBI has made it clear that it does not recommend ransom payment, and that paying does not guarantee that the data will be restored.
Payment not only benefits the attackers, but can also encourage further crimes of the same type. The expectation that “if the files are encrypted, we can always pay and somehow recover” is dangerous in practice.
Why Traditional Antivirus Alone Is Not Enough
Traditional antivirus products are fundamentally designed to identify and block known malicious programs using signatures and definition files. This approach is still useful today, but it is no longer enough on its own against unknown variants, attacks that abuse legitimate tools, or ransomware that moves laterally after intrusion and only then begins encryption. Microsoft itself provides Microsoft Defender Antivirus as a standard Windows protection layer, while also assuming that enterprises will need products such as Microsoft Defender for Endpoint, which cover post-compromise detection, investigation, and response.
In enterprise environments especially, the issue is not only whether something can be detected, but also how to determine which device the attack entered through, how far it spread, what should be stopped first, and what needs to be investigated. Windows Defender is effective as a basic protective baseline, but it is not designed to fully cover enterprise ransomware defense on its own.
Regardless of whether you already have some security software installed, it is important to think separately about pre-intrusion defense, post-intrusion visibility, and recovery capability. If building that internally is difficult, consulting a security company can help you create a more complete defensive structure.For Ransomware Protection, Choose CyberCrew Contact Us for a Free Consultation and Estimate
How to Choose Ransomware Protection Software
Looking only at product names can be overwhelming because there are so many options. The decision becomes much easier if you organize it around three points: the layer of defense, your company’s size and IT structure, and whether the product can coexist with your existing software.
Choose Based on the Layer of Defense It Covers (Before Intrusion, After Intrusion, and Recovery)
Ransomware protection software becomes easier to understand if you think of it as falling broadly into three categories based on role.
The first is EPP (Endpoint Protection Platform), which is designed to prevent intrusion itself. It blocks access to malicious websites, prevents malicious attachments from executing, and stops both known and unknown malware from running, helping to close the main entry points for attacks.
The second is EDR (Endpoint Detection and Response), which is designed for the scenario where an attacker gets in despite preventive defenses. It helps detect suspicious activity, visualize what is happening on the endpoint, and connect that visibility to investigation and containment.
The third category is backup and recovery-oriented software, which is designed to detect signs of encryption, protect files, and help restore affected data.
In other words, these are not all-in-one miracle products that solve everything by themselves. Each type protects a different part of the problem. When thinking about what your organization needs, it is important to understand that difference and consider how the layers should be combined.
Choose Based on Your Company Size and IT Structure
As a rough guide, it is easiest to think in these terms: for individuals and SOHO use, focus on whether one product can provide broad coverage; for small businesses without dedicated IT staff, focus on whether deployment and day-to-day operation remain light; and for mid-sized companies with internal IT staff, focus on whether the product supports response using logs and alerts.
For individual use or primarily remote work, an all-in-one EPP product is often enough. For small businesses without dedicated IT staff, it is usually better to prioritize light operational burden, the ability to layer the product onto existing software, and recovery support features. By contrast, for mid-sized companies with internal IT teams and a larger number of devices, a setup that includes EDR in addition to EPP is more realistic because it supports investigation and containment after intrusion.
In organizations that already have some security software in place, strengthening weak points through an additional product is often smoother than replacing everything outright.
Choose Based on Whether It Can Coexist with Existing Security Software
In real-world environments, one very common concern is, “Replacing everything we already have would be a major burden.” That is why products such as AppCheck, which are designed to coexist more easily with existing antivirus software, can lower the barrier to adoption. They are especially suitable for organizations that want to keep their current environment while strengthening ransomware-specific defenses.
On the other hand, with EDR or integrated endpoint suites, it is important to avoid feature overlap and management conflicts through proper design.
Microsoft also provides deployment models such as EDR in block mode, allowing Defender to work alongside another primary antivirus product, but the right architecture still depends on the specific requirements. The decision between “add on” and “replace” is shaped not only by technical performance, but also by operational design.For Ransomware Protection, Choose CyberCrew Contact Us for a Free Consultation and Estimate
Core Functions to Look for in Ransomware Protection Software
Before comparing product names, it helps to understand what kinds of capabilities you should actually be looking for. Once that is clear, comparison tables become much easier to read. Ransomware defense is not just about “removal.” It should be thought of as a full process that includes reducing intrusion, detecting attacker activity, and supporting recovery.
Blocking Malicious Sites and Infection Routes
Many ransomware infections begin through suspicious email, malicious URLs, or vulnerable internet-facing devices.
In fact, according to the National Police Agency’s “Police White Paper 2023”, VPN appliances accounted for 62% of ransomware infection routes in 2022, while Remote Desktop Services accounted for 19%. In the Police White Paper 2024, the 2023 breakdown remained similar at 63% through VPN devices and 18% through Remote Desktop Services, showing that remote access routes continue to be major entry points.
That is exactly why, as recommended in CISA’s StopRansomware Guide, it is important to treat email filtering, URL filtering, and malicious site blocking as fundamental front-line controls.
Real-Time Malware Detection and Removal
Real-time detection means continuously monitoring what happens on the endpoint, such as file creation and execution, outbound communication, and encryption-like behavior, then blocking or isolating suspicious activity as soon as it is detected.
Security products generally combine two broad approaches: signature-based detection, which is strong against known threats, and behavior-based detection, which focuses on unusual actions and suspicious patterns of operation. Signature-based detection has long been widely used, but it has clear limits against unknown variants.
That is why, in practice, it is safer to choose products that combine both approaches rather than relying entirely on one or the other.
Automatic Definition and Engine Updates
When dealing with known malware and its variants, the freshness of the definition files and detection engine matters. Microsoft also notes that keeping Defender Antivirus fully up to date is essential in order to protect against new malware and evolving attack methods.
If updates depend on manual action, they tend to be delayed in busy environments, and that delay becomes a gap in protection. Choosing software with automatic update capability helps reduce that risk.
Automatic Backup and File/Data Recovery Features
When thinking about ransomware protection, people naturally focus on preventing infection. In reality, however, recovery functionality is also extremely important.
No matter how many protections you put in place, it is not realistic to assume you can prevent 100% of incidents. That is why the presence or absence of a mechanism that can minimize damage once encryption begins makes a major difference.
For example, products such as AppCheck monitor file changes in real time and, when behavior suggesting encryption is detected, they can back up files or restore them.
It is not enough just to store data somewhere. When comparing products, it is worth paying close attention to whether the software can stop suspicious encryption in progress or return files to the state they were in just before the attack.
Behavior-Based Detection of Abnormal Activity (Without Relying Only on Pattern Files)
One of the most important principles in preparing for unknown ransomware is not relying only on signatures for known threats. In recent years, attackers have continued to release slightly modified variants and entirely new methods, and there are clear cases where definition files alone cannot keep up.
That is why behavior-based detection deserves attention. Products built around this model do not depend only on pattern files. Instead, they monitor suspicious file modification activity itself, making them better suited to responding to previously unseen ransomware.
Some of these products are also designed to coexist more easily with existing security software, which lowers the barrier to adoption. If fast response to new strains and variants matters to you, this design philosophy is highly important.For Ransomware Protection, Choose CyberCrew Contact Us for a Free Consultation and Estimate
Recommended Ransomware Protection Software Comparison [Latest 2026 Edition]
It is easiest to begin with a comparison table so you can understand the overall landscape, then move on to the strengths of each product. The prices and trial availability below are organized based on each vendor’s official website as of March 10, 2026.
Product Name Type Target Scale Price Range Free Trial One-Line Characteristic AppCheck / AppCheck Pro Behavior-based / recovery-support type Individuals to SMEs, including file servers From JPY 9,600 per device per year, Server from JPY 360,000 per year (tax excluded) Yes Easy to coexist with third-party AV ESET HOME Security EPP (broad protection) Individuals to small businesses From JPY 4,750 per year 30 days Lightweight and multi-OS Norton 360 EPP (all-in-one for individuals) Individuals to SOHO From JPY 4,780 per year Trial path equivalent to 30 days Includes VPN and backup Virus Buster Cloud EPP (broad protection) Individuals to small businesses From JPY 7,480 per year 30 days Strong domestic support in Japan EDR products (Cybereason / CyCraft AIR, etc.) EDR Mid-sized companies to large enterprises Contact vendor Contact vendor Strong for post-intrusion visibility and response As the table shows, the broad pattern is this: individuals tend to do best with all-in-one products, small businesses tend to benefit from products that are easy to add and operate, and larger companies generally need a combination of EPP and EDR. Whether you prioritize ransomware-specific protection or all-around coverage will change which product makes the most sense.
AppCheck / AppCheck Pro
AppCheck is a product with particular strength in detecting, blocking, and helping recover from ransomware by monitoring abnormal file changes in real time, without depending solely on pattern files. One major advantage is that it is well suited to unknown ransomware and is also easy to run alongside existing antivirus products.
In fact, its official messaging explicitly highlights coexistence with third-party software, which makes it a strong fit for small businesses that cannot realistically throw away everything they already have.
Pricing starts at JPY 9,600 per device per year for AppCheck Pro, JPY 360,000 per year for the Windows Server edition, and JPY 90,000 per year for CMS Cloud. There is also an evaluation version available, which makes it easier to test before adoption.
Because it also offers shared-folder protection and server-oriented editions, it is suitable for organizations that need to protect file servers as well. Its strengths include resistance to previously unknown ransomware, easy coexistence with third-party software, and relatively light operational burden after deployment.
Its limitation is that it is not designed as a single product to cover every part of enterprise security, such as email security, MDM, or identity protection. In practice, it often fits better as an additional ransomware-focused layer on top of an existing EPP than as a one-product answer for the entire environment.
For small businesses that want to strengthen ransomware defense first, it is one of the strongest candidates.
ESET Security Software
ESET is a well-balanced all-around security product that combines light system impact with broad protection. Its individual-user product pages clearly highlight multi-OS support, making it easy to use across Windows, macOS, Android, and iOS, and it also offers a 30-day free trial. Across the broader ESET portfolio, the company states that it protects more than 110 million users worldwide and is used in over 200 countries and territories. Its collaboration history with Google Chrome around unwanted software handling is also a reasonable indicator of technical credibility.
Pricing starts at JPY 4,750 per year for the Essential tier, and multi-device plans are also available. Its strengths include lightweight performance, good general coverage including anti-fraud capabilities and multi-OS support, and easy expansion from personal use to small offices. Its limitation is that if your top priority is ransomware-specific automatic recovery like AppCheck, its role is somewhat different. Even so, for people who want one product that provides broad protection, it is a very easy product to work with.
Norton 360
Norton 360 is a well-packaged all-in-one option for individuals, SOHO users, and people working from home. According to its official materials, it includes protection against viruses, malware, and ransomware, along with a VPN, password manager, and Windows cloud backup. Higher-tier plans also include dark web monitoring.
It is the kind of product that people who are not highly technical can easily feel is “good enough to protect me in one package.” The Standard plan starts at JPY 4,780 per year.
Its strengths are that it includes the main features most individual users need and works well for remote work or side-business use. Its limitation is that it is not intended for enterprise-wide centralized administration or full-scale incident investigation, so it is better suited to individuals and smaller environments than to company-wide endpoint defense.
For individuals who are unsure what to choose, it is one of the strongest starting options.
Virus Buster Cloud
Virus Buster Cloud stands out for its easy-to-understand feature presentation and support structure tailored to the Japanese market. Its official positioning highlights layered defense, ransomware protection, and anti-fraud protection, and it also offers a 30-day free trial.
It is a good fit for readers who value the reassurance of a domestic brand, along with easy use for families or small businesses. Pricing starts at JPY 7,480 per year.
Its strengths include support and explanations that align well with the Japanese market and ease of use as an all-around security product. Its limitation is that compared with EDR-style products for post-intrusion investigation or AppCheck-style recovery-focused products, its role remains more centered on broad protection. If your priority is “I want something that feels more domestically familiar than a foreign vendor,” it is definitely worth considering.
EDR Products (For Mid-Sized Companies and Large Enterprises)
If a mid-sized company or larger organization is seriously considering ransomware protection, it should look beyond EPP alone and include EDR in the conversation. Cybereason EDR is designed to continuously monitor suspicious behavior on endpoints, analyze it with cloud-based AI, visualize the overall attack chain, and support rapid response. In Microsoft’s own definitions, EDR is the layer responsible for near-real-time advanced attack detection, enterprise-wide visibility into the compromise, and execution of response actions. At the same time, EDR is not something you simply install and forget. It requires people who can review alerts, decide when to isolate an endpoint, and investigate what happened. Products such as CyCraft AIR, which emphasize AI and automation, can reduce some burden, but they still assume internal staff or an external provider will handle operations. Pricing for these products is generally available only on request, and they may be overpowered for companies without internal IT staff. They are best suited for organizations that already have an IT or security function and need visibility and response capabilities after intrusion.
To decide which product is right for your environment, it is important to first understand your actual security risks. At CyberCrew, we use vulnerability assessments and penetration tests to make those risks visible.

Recommended Tools by Objective
Even within “ransomware protection,” the best product changes depending on what you want to prioritize. If you organize the decision around whether you want to focus first on preventing intrusion, visualizing activity after intrusion, or protecting shared servers, it becomes much easier to find a product that matches your environment.
Best for Ransomware Detection on Endpoints
For mid-sized companies with internal IT staff that want to detect abnormal behavior at an early stage, including after intrusion, EDR products are a strong choice.
EDR continuously monitors suspicious activity on endpoints and is designed not only to detect it, but also to make it easier to understand which device was affected, what happened there, and how the attack progressed.
For example, products such as Cybereason EDR make it easier to follow the attack chain and decide on countermeasures before damage spreads further.
That said, EDR is not simply something you install and then consider done. In addition to detection capability itself, it is important to confirm whether the volume of alerts is operationally manageable, and whether the company can realistically support isolation, investigation, and response once alerts begin to arrive.
Before deployment, it is wise to look not only at the functions themselves, but also at whether the product realistically fits your existing operations.
Best for Blocking Ransomware on Endpoints
For small businesses without dedicated IT staff, it is important to choose a product with both strong preventive capability and an operational burden that stays manageable after deployment.
With that in mind, all-around EPP products such as ESET, as well as more ransomware-focused products such as AppCheck, are both realistic candidates.
For example, if you want one simple product that provides broad protection, ESET is easy to work with. If you want to keep your current antivirus in place and simply add a stronger ransomware-specific layer, AppCheck is often the better fit.
The key point is not to choose based only on how many features are listed. You also need to think about who will manage the product afterward and how much work will be required to respond to updates and notifications. Otherwise, even a strong product may become difficult to use in practice. For small businesses, the question is not only how strong the product is, but whether it can realistically be operated without strain.
Best for Ransomware Detection on File Servers
In companies that rely on shared file servers, a single infected endpoint can be enough for ransomware damage to spread across the entire shared environment. What begins as one user’s PC problem can quickly become encryption of department-wide business data and shared documents, with major operational impact. That is why, in this area, it is important to think not only about endpoint protection, but also about how to protect the server side and shared-folder side. From that perspective, AppCheck Server, which explicitly emphasizes server protection and shared-folder protection, is one of the easier products to evaluate. Its ability to detect suspicious encryption-like behavior, block it, and reduce damage propagation into shared storage is a major strength. And if it can be added to the existing environment without large architectural change, that also makes it easier to strengthen protection without forcing a major operational shift. For companies that need to protect shared file servers, it is a realistic option for reducing the risk of ransomware spreading across the wider environment.For Ransomware Protection, Choose CyberCrew Contact Us for a Free Consultation and Estimate
What to Do If You Have Already Been Infected with Ransomware
From here, the focus shifts to what to do if infection has already happened. It is naturally a high-pressure situation, but the order of actions matters. If you get that order wrong, the damage can spread further. The key is to move without panic: first contain the spread, then confirm the situation, and only after that move to formal reporting and consultation.
Four Immediate Steps to Take Right After Infection
Immediately disconnect the device from the network. If it is wired, unplug the LAN cable. If it is wireless, turn off Wi-Fi. If necessary, also stop any shared connections. The Tokyo Metropolitan Police Department also explicitly advises isolating infected devices from the network. This is to prevent lateral movement into other endpoints and shared folders.
Do not casually power off the device. Instead, identify the ransomware type. The Tokyo Metropolitan Police Department advises not to turn off the infected endpoint. This is because information needed for decryption or investigation may remain in memory or logs. Record the file extensions, ransom note, and detection name so you can determine what family of ransomware you may be dealing with.
Check No More Ransom for free decryption tools. No More Ransom provides a repository of decryption tools and keys, and depending on the ransomware family, you may be able to recover without paying. Of course, it does not support every family, but it is absolutely worth checking.
Report the incident and consult with the National Police Agency, Tokyo Metropolitan Police Department, and IPA. The National Police Agency advises victims to report the incident to the nearest police station or cybercrime consultation desk, bringing communication logs and related evidence if possible. IPA also has a corporate consultation contact point. For companies in Tokyo, the Tokyo Metropolitan Police cyber consultation desk can also be used. CyberCrew operates an emergency incident response desk, where a specialized security team can respond quickly.
Consulting outside parties gives you more information for limiting the spread of damage and preventing recurrence.
Should You Pay the Ransom?
The short answer is: we do not recommend paying the ransom.
It is completely understandable to think, “We need the data back as quickly as possible, even if that means paying,” when operations are stopped and important files cannot be opened. But even if you pay, there is no guarantee that the attacker will actually decrypt the data, nor that the environment will be fully restored.
On top of that, the payment itself becomes profit for the attacker and helps sustain the next wave of attacks. From a practical standpoint, it is not a reliable resolution path, and from an ethical standpoint, it is also deeply problematic.
That is why, even after infection, the correct priority is not to assume payment, but to isolate the affected devices, investigate the scope, confirm whether recovery is possible, and consult the relevant authorities and specialists.
How to Choose Security Software After Infection
If you are serious about preventing recurrence, the right time to review your security controls is immediately after an infection.
In practice, if you were successfully attacked once, that strongly suggests there was a weak point that had been overlooked. Going forward, it is best to think separately about EPP, which helps prevent intrusion itself, and EDR, which helps detect suspicious activity after intrusion and connect it to investigation and response. Ideally, both layers should be considered.
What matters first is organizing what your current software can see and what it cannot. Product selection should start from a comparison table like the one in this article, then be narrowed based on your company’s actual operating model and staffing.For Ransomware Protection, Choose CyberCrew Contact Us for a Free Consultation and Estimate
What You Should Do in Addition to Installing Ransomware Protection Software
Installing software alone is not enough.
As both the National Police Agency and CISA repeatedly emphasize, ransomware defense needs to be built as layered protection. At minimum, the following five measures should be implemented together with software deployment.
Keep the OS and software fully up to date Internet-facing VPN devices and public servers with known vulnerabilities left unpatched are classic entry points. National Police Agency materials also continue to show that most intrusions begin through VPN or RDP paths. Patch management is not flashy, but it remains one of the most important preventive measures. Perform regular offline backups A backup that remains directly connected to the network is not enough. Offline storage, encryption, immutability, and restoration testing are all part of making a backup truly meaningful. CISA strongly recommends this as well. Run training on how to handle suspicious email and attachments Phishing and impersonation remain major entry routes. Technical controls matter, but it is also important to build a workplace culture where suspicious email is not casually trusted. Minimize access privileges If anyone can freely modify shared folders, a single infected device can quickly turn into a company-wide incident. Just reviewing administrative privileges, shared access rights, and maintenance accounts and removing unnecessary permissions can significantly reduce the scope of damage. Strengthen employee security awareness and reporting habits Ransomware attacks exploit human judgment as much as technology. Basic awareness training and clear reporting rules make initial response much faster. Software becomes far more effective when combined with this kind of operational discipline.

For Ransomware Protection, Choose CyberCrew’s Vulnerability Assessment and Penetration Testing
Ransomware protection is not something that can be completed through software selection alone.
According to National Police Agency materials, internet-facing routes such as VPN appliances and Remote Desktop Services continue to be major entry points. If those external weaknesses remain in place, adding endpoint security products alone often results in incomplete defense.
Why Vulnerability Assessments and Penetration Testing Help Defend Against Ransomware
Ransomware damage is not always caused simply by someone opening a suspicious email. National Police Agency materials also describe many cases believed to have begun through VPN or RDP vulnerabilities, or weak credentials that were abused by attackers. That is why finding and fixing external-facing weaknesses before attackers do is such an effective preventive measure.
Vulnerability assessments are well suited for broadly identifying weaknesses in exposed assets and systems. By contrast, penetration testing is better suited to validating how far those weaknesses could realistically lead to real-world impact.
In ransomware defense, using these two approaches appropriately makes it much easier to reduce the number of entry points and address the highest-priority risks first.
What Makes CyberCrew’s Vulnerability Assessment and Penetration Testing Different
CyberCrew’s penetration testing is designed as a practical service that uses attacker-perspective simulation to verify how far an attacker could really break through and what business impact would follow. Rather than simply listing vulnerabilities, it is built to reveal the real risk based on system design and operational context.
Its vulnerability assessment service also clearly states a policy of combining automated and manual testing in order to deliver broad coverage at relatively low cost and high quality.
CyberCrew is also a registered service provider under the Ministry of Economy, Trade and Industry’s Information Security Service Standards. Its service registration materials indicate that full penetration testing, one retest, and fully in-house delivery without outsourcing are included as part of the standard offering.
For companies that want not only a report, but also understandable findings and support for practical improvement, CyberCrew provides security assessment and guidance designed around real operations.
Pricing and Cost
CyberCrew offers vulnerability assessments from JPY 100,000, web application penetration testing from JPY 200,000, and network penetration testing from JPY 1,000,000.
Actual pricing varies depending on scope, environment, and testing objective, so estimates are provided individually.

Frequently Asked Questions About Ransomware Protection Software
What is ransomware protection software?
Ransomware protection software is designed to detect encryption behavior and suspicious file modification, block that activity, and in some cases support recovery as well. Compared with ordinary antivirus, the difference is that it is built with a stronger focus on previously unseen ransomware and on limiting damage after compromise.
Which security software is strong against ransomware?
By use case, Norton 360 is a strong choice for individuals, AppCheck is easy to add for small businesses already running other software, and EDR products are strong for companies with internal IT staff that want visibility after intrusion as well. If you are unsure, the comparison table in this article is the fastest place to start.
Are there any free ransomware protection tools?
There are very few fully free products that can realistically be called sufficient for enterprise operations.
Microsoft Defender, which is included with Windows, provides a baseline level of protection, and many vendors also offer 30-day trials or evaluation versions. But for enterprise use, paid versions with management and recovery features are usually the realistic choice.
Is Windows Defender alone enough?
As a minimum baseline for individuals, it is useful.
However, it is not enough on its own for enterprise needs such as post-intrusion visibility, investigation across multiple endpoints, containment, and centralized operational management. For business use, it is more realistic to consider higher-level products such as Defender for Endpoint or separate EPP/EDR solutions.
How much does ransomware protection software cost?
All-in-one products for individuals generally range from the JPY 4,000 level to the low JPY 10,000s per year.
For small businesses, pricing can range from tens of thousands to hundreds of thousands of yen depending on the number of devices and whether server protection is included. EDR products are often priced on a vendor-quotation basis. You should estimate not only the license price, but also the staffing needed to operate the product properly.
What should I do if I am infected with ransomware?
First disconnect the affected device from the network, avoid turning it off unnecessarily, and check No More Ransom to see whether decryption is possible.
After that, consult public organizations such as the police and IPA, and if needed, contact CyberCrew early to confirm the scale of the damage and discuss recurrence prevention.
If you respond in the right order, it becomes much easier to prevent further spread and avoid delays in recovery. For more detail, see the section in this article on what to do after infection.Contact CyberCrew for a Free Consultation and Estimate
Summary
The conclusions of this article come down to three main points.
First, ransomware protection should not be thought of as “we already have antivirus, so we are safe.” It should be designed in three layers: defense before intrusion, detection after intrusion, and recovery capability.
Second, product selection works best when it is matched to the use case. For individuals, Norton 360 is a realistic choice. For small businesses, AppCheck is a practical option. For mid-sized companies and larger organizations, a configuration that combines EPP with EDR is generally the most realistic.
Third, real effectiveness comes only when software is combined with broader controls, including hardening internet-facing assets such as VPN and RDP, offline backups, and employee education.
If you are unsure where to begin, a practical first step is to compare free trials or evaluation versions that match your environment. And if you are concerned about public-facing systems or VPN exposure, you should think beyond software alone and include vulnerability assessments and penetration testing in the conversation.
Ransomware protection is easier and more realistic when you begin before an incident happens. The earlier you start, the more options you have.Contact CyberCrew for a Free Consultation and Estimate
