of your backup data.

Backup protection reimagined

How Blocky Reliably Secures Your Backup Data

Blocky for Veeam® protects your Windows-based backup system at the file system and disk levels. The software combines intelligent access control with tamper-proof WORM protection.

Intelligent protection mechanisms running in the background

Blocky acts as an invisible security layer between your Veeam® application and the file system. Every write operation is verified for authenticity, and only authorized processes are permitted to modify data. This ensures your backups remain intact, even if an attack on the server is successful. Thanks to native integration with Windows, Blocky runs without additional hardware or separate operating systems. The system is up and running in just a few minutes and operates completely transparently in the background.

Technological Foundations

  • Fingerprinting: Detection and authorization of authorized processes at the system level
  • WORM Technology: Protects stored backups from tampering or deletion
  • Zero-Trust Write Control: Blocks unauthorized write and delete access
  • Disk Protection: Protection at the physical drive level against malicious interference
  • Centralized Management: Control of Blocky instances via a management UI

Zero-Trust Backup Security as a Competitive Advantage

How Blocky for Veeam® Boosts Margins, Reduces Risks, and Differentiates Portfolios

The market for managed backup and recovery services is highly competitive. Many providers rely on similar technologies, particularly Veeam, and now differentiate themselves to customers only through price, contract terms, and additional services. At the same time, the rise in ransomware attacks has led to customers no longer simply buying “backup,” but rather resilience and guaranteed recoverability.

Zero-Trust Backup Protection with Application Whitelisting

How Blocky for Veeam® Reliably Protects Backup Repositories Against Modern Ransomware

The integrity of backups is critical to the resilience of modern IT infrastructures.
Since traditional security mechanisms are primarily signature-based, they have limited ability to detect zero-day attacks or legitimate but manipulated system processes. “Living-off-the-land” techniques leverage existing system tools such as PowerShell or WMI to operate without traditional malware.

Here's how Blocky seamlessly integrates into your Veeam® infrastructure

Blocky is designed for Windows-based Veeam® backup repositories and leverages native system features to ensure maximum security with minimal complexity.

System Architecture & Integration

Blocky runs directly on your existing Windows Veeam® repository server—without any additional hardware or virtual machines. The software operates at the kernel level via a Windows filter driver and monitors all write and delete operations.

Only the authorized Veeam backup application is allowed access via a unique fingerprint; all other processes are automatically blocked before they can cause any damage.

Thanks to native integration with NTFS and ReFS file systems, the performance of your backups remains unchanged, ensuring that security and efficiency go hand in hand.

In addition, Blocky makes it easier for administrators to meet compliance requirements, assists with audits, and ensures that restores can be performed reliably and quickly at any time.

Security and Management Features

  • Zero-Trust Principle: Every write operation is verified; no process is granted blanket permissions.
  • WORM File System Protection: Automatic conversion of backup volumes into “Write Once, Read Many” storage.
  • Disk Protection: Protection at the physical drive level against tampering and deletion.
  • Multi-factor authentication (MFA): Securing administrative actions through two-factor login.
  • Centralized management UI: Management of multiple Blocky instances via a unified interface.
  • Logging & Alerts: Complete recording of all accesses and notifications in case of suspicious activity.
