Why Blocky?
Blocky provides critical protection for your Veeam backup environment by securing the VBR server volumes where backup jobs originate—a protection layer often overlooked in comprehensive backup security strategies. By protecting your Veeam backups directly at the source, Blocky ensures your data remains recoverable even in the face of sophisticated ransomware attacks.
Key Capabilities
- WORM Shield – Ensures data protection on ReFS and NTFS volumes to prevent ransomware from altering backups
- Zero Trust Architecture – Only explicitly authorized processes can interact with protected backup data
- Multi-Factor Authentication (MFA) – Strengthens administrative access security with optional MFA
- Disk Protection – Prevents physical disk tampering—adding protection beneath the file system layer
- Real-Time Alerting – Detects and records access attempts, supporting incident response
- Centralized Control – Enables uniform protection policies across multi-site or distributed environments
Where Blocky Fits In
Protection Tiers
✅ Standalone Protection:
Blocky provides comprehensive protection for the Windows-based Veeam server. No Linux. No hardware. No complexity.
✅ Complements Other Storage Solutions:
Blocky adds critical Tier 1 protection to your backup strategy by securing the local VBR server volumes. This creates a layered defense strategy that improves Object First, ExaGrid, or cloud storage like Wasabi, ensuring the fastest, most secure recovery possible by protecting VBR backup volumes at their source.
✅ Centralized Management:
Blocky’s unified control panel allows you to implement consistent protection policies across your entire environment with real-time monitoring and simplified administration for multiple sites.
How Blocky Works
When installed, Blocky:
-
- Transforms standard NTFS and ReFS volumes into hardened WORM volumes
- Creates a zero-trust environment where only authorized Veeam processes can modify data
- Stops all unauthorized access for write, delete, and encryption to the backup volumes
- Provides real-time detection and alerts for unauthorized access attempts
- Delivers disk-level protection to prevent physical tampering with storage media
- Enables centralized policy control for unified security across multiple locations
Blocky 3.5 now available with two powerful new features:
- Multi-factor authentication significantly strengthens protection at the system level, ensuring administration access is secure beyond just password protection.
- Disk Protection provides an additional layer of resilience by actively protecting the physical disks against manipulation, securing data not just at the file system level but at the hardware level as well.
