Blocky for
Ransomware Protection

Blocky is the only solution to harden Veeam® Windows repository without adding extra servers, specialized storage, or requiring Linux. Blocky installs on the Windows server to harden the NTFS and ReFS volumes. Blocky instantly transforms Veeam® into a hardened, zero-trust environment. The Veeam® repository becomes an immutable, WORM-only volume, and only trusted Veeam processes can delete, encrypt, or modify backup data. Ransomware (malware) is blocked.

  • Active Intrusion detection - Blocky monitors and alerts on any unauthorized attempt to access data, providing an early warning of malware activity.
  • Immutable, Zero-Trust Environment - Blocky instantly transforms the Veeam backup into an immutable WORM volume with granular access controls that defends against malware and unauthorized access to the backup data.
