S&J Launches New Solution 'KeepEye RansomSafe' to Block Ransomware Encryption

S&J Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Nobuo Miwa; Securities Code: 5599; hereinafter 'S&J'), which operates cybersecurity businesses including security monitoring services and incident response, will begin providing 'KeepEye® RansomSafe® (KeepEye RansomSafe)'—a solution that detects and removes ransomware encryption attacks—starting Tuesday, June 16, 2026.

KeepEye RansomSafe is a service developed by combining S&J’s know-how from SOC monitoring and analysis since its founding in 2008, with its development expertise in creating multiple security solutions. It prevents ransomware encryption attacks with high accuracy by detecting and eliminating threats before the encryption process begins.

In addition, when an attack is detected, S&J’s security advisors will collaborate to provide comprehensive support—not only detecting and removing ransomware, but also identifying other compromised areas and assisting with recovery.

■ Defense Against Ransomware Attacks Even When EDR is Evaded or Disabled

While companies continue to strengthen their security measures, sophisticated ransomware attacks that evade or disable existing products such as EDR are increasing. Ransomware attacks have become a persistent threat, and the risk of business disruption due to such attacks cannot be ignored by any organization. To stop attacks that significantly impact business operations, specialized defense solutions targeting ransomware are needed in addition to existing security measures.

S&J is launching KeepEye RansomSafe by combining its SOC operational insights with its proven development capabilities, aiming to reduce the risk of business interruption caused by ransomware encryption attacks.

■ Overview of KeepEye RansomSafe

KeepEye RansomSafe is a solution that can be used alongside existing security products. It detects and removes ransomware attack behaviors using S&J’s proprietary detection logic.

About the KeepEye Series

The KeepEye® series is S&J’s proprietary agent-based endpoint monitoring service model. The newly added 'KeepEye RansomSafe' is a solution specialized in defending against ransomware encryption.

■ Key Features of KeepEye RansomSafe

The main features designed to proactively protect customers’ systems and data from ransomware attacks are as follows:

1. Early Intrusion Detection (Detection and Response Before Execution)

【1】Unlike conventional post-execution behavior detection, analysis begins as soon as a file reaches the endpoint, enabling early threat identification and response

2. Behavior-Specific Analysis (High-Precision Analysis Specialized for Ransomware)

【1】Analyzes behaviors specific to ransomware, such as 'encryption processes' and 'ransom note generation'
【2】Achieves high-precision detection using AI analysis based on numerous ransomware samples
【3】Capable of detecting threats that are difficult for traditional EPP or EDR to identify, such as malware disguised as legitimate files or executable files (EXE) deployed by abusing legitimate programs

3. Reduced False Positives to Minimize Business Impact

【1】Learns the behavior of standard OS functions and business software to avoid disrupting legitimate operations
【2】Identifies malicious behaviors even when disguised as legitimate software, accurately defending against attacks only

4. Incident Response Support by Experts

【1】When ransomware is detected, support is provided to investigate the scope of impact, assuming prior intrusion attempts may have occurred
【2】Security advisors with extensive response experience provide 24/7/365 initial response support
【3】Detailed investigation and recovery support available as needed*

*Ongoing support requires a separate contract
