Airtight ransomware protection

CryptoGuard technology in Sophos Endpoint monitors file contents for malicious encryption, blocking offending processes on the victim's computer and on compromised network-connected devices. Our universal approach protects your data from new and novel file encryption attacks and automatically reverts any encrypted files to their original state. CryptoGuard's Master Boot Record (MBR) protection safeguards your hard drives from advanced ransomware designed to render computers unbootable.

Robust defense against remote ransomware

According to Microsoft's 2024 Digital Defense Report​, remote encryption — where an attacker uses an unmanaged device to encrypt files in the same network — is used in 70% of successful ransomware attacks​. Most endpoint security solutions, however, are unable to protect you against this increasingly prevalent attack technique.

Sophos Endpoint is the industry’s most robust zero-touch endpoint defense against remote ransomware, thanks to our universal proprietary CryptoGuard technology.
