Glasswall CDR

Content Disarm and Reconstruction (CDR) is an advanced cybersecurity technology designed to neutralize threats, such as malware and ransomware, within files.

Every file entering your organization introduces risk

Attackers exploit inherent trust by hiding malware inside common file types that appear safe to users and security tools alike.

Detection-based tools rely on identifying known threats through signatures or behavioral analysis. These approaches generate noise, miss zero-day malware, and force your team into constant reaction mode.

Glasswall CDR takes a Zero Trust, prevention-first approach

Glasswall CDR removes active content and rebuilds files into safe, usable versions.

The result:

  • No reliance on signatures
  • Protection against known and unknown threats
  • Safe files delivered to users and systems
  • No need to predict attacker behavior

Close the detection gap

You can't detect every threat. Glasswall CDR eliminates file-borne risk without relying on threat identification. Objective testing across 8.27 million malicious files demonstrates why prevention is essential.
