About Glasswall

Glasswall is a cybersecurity company that protects government agencies and commercial organizations from malicious files with its Content Disarm and Reconstruction (CDR) technology. Unlike traditional detection-based methods, Glasswall employs a zero-trust approach, which removes the ability for malware to exist in files altogether.

Trusted by the world’s most secure agencies

Our battle-hardened CDR technology is mandated for use as a file filter in Cross Domain Solutions by the NSA and is trusted by the world’s most sophisticated security establishments.
