Active Defense at the Storage Layer

Independent analyst analysis of RackTop's patented Active Defense technology.

This analyst brief examines Active Defense — the patented RackTop technology that stops ransomware and insider threats at the storage layer in real time. The brief covers the technical architecture, threat model, and operational implications for enterprise and federal environments where data loss is not an option.

• Active Defense Defined

  Active Defense is a patented RackTop technology that monitors every file operation in real time, identifies malicious patterns, and terminates the offending session — typically within one second.
• Storage-Layer Enforcement

  Unlike endpoint or network security, Active Defense operates at the point where data is written — making it impossible for an attacker to bypass by compromising the OS, a user session, or a backup agent.
• Zero Dwell Time

  By acting at the I/O layer, Active Defense eliminates the dwell time that allows ransomware to encrypt thousands of files before detection. Attacks are stopped after a handful of writes.
• No False Positives by Design

  Active Defense uses behavioral analysis tuned to storage access patterns — not signature matching — so it catches novel ransomware variants without flagging legitimate bulk operations.
• Intelligent Bulk Remediation

  When Active Defense terminates an attack, Intelligent Bulk Remediation automatically identifies and rolls back only the affected files — restoring data in minutes without manual triage.
