RansomStop is an AI-based ransomware detection and response tool designed to stop active ransomware encryption before it spreads and disrupts business operations by detecting malicious file encryption activity and responding automatically in seconds. It focuses on real-time containment and protection of critical infrastructure, such as web servers, application servers, SQL servers, domain controllers, NAS appliances, hypervisors, and cloud storage, by analyzing file entropy, access patterns, and metadata to recognize unauthorized encryption rather than relying on process intent or signatures, making it resilient even against evasive or “living-off-the-land” attacks. Once ransomware activity is detected, RansomStop can automatically disable compromised accounts, terminate malicious processes, and block attacker IPs, helping prevent widespread damage and operational downtime without waiting for manual intervention.
