The Glasswall CDS Content Filter (CF) quickly processes documents, removing any malformed code, structural imperfections, malicious scripts, or embedded malware. A clean, compliant and validated document is regenerated, disarming any hidden threats while producing a sanitized file that is safe to use.


Apply policy based on the risk posture at individual, department, enclave or organisation level. Glasswall manages risk factors such as Macros, JavaScript, embedded links, images and embedded files. Control of files, and the ability to implement a standard file policy, is given back to the security administrator.


Glasswall not only stops document based attacks, it allows users to gain unique insight into those attacks. Glasswall FileTrust™ Threat Intelligence provides unique reporting on how files and documents are manipulated to target people in our clients' organisations.
