About

Glasswall is a cybersecurity company based in London, United Kingdom working in data protection, email security, network security +2 more.

Glasswall is a cybersecurity company that protects governments and commercial organisations from malicious files. Its core technology is Content Disarm and Reconstruction (CDR), a zero-trust, prevention-first approach that rebuilds files into safe, usable versions and removes malware and ransomware without relying on signatures or detection. The company also offers AI-powered predictive threat scoring through Glasswall Foresight, which analyses CDR structural telemetry to identify unknown and zero-day file threats, and a data loss prevention capability for Office documents. Its products are available as APIs, SDKs and applications, deployable in cloud, on-premises, air-gapped and disconnected, intermittent or limited (DDIL) environments. Glasswall supports high-assurance and classified networks, including Five Eyes and cross domain solution deployments, and works with a partner network to deliver file protection.
