Content Disarm and Reconstruction (CDR)


File-based cyber-attacks are increasing and now present the biggest danger to the security of organisations around the world. Whether through FTP transfers, USB uploads, or attachments and emails, hackers exploit vulnerabilities in the structure and Active Content of everyday files such as PDFs, Word, Excel, and PowerPoint, compelling enterprises to deploy ever more complex and meshed security solutions.

Anti-virus, firewalls, sandboxes and AI – you may have them all, but still threats get in. Malicious content is increasingly complex, advanced and sandbox-aware meaning existing security layers need to constantly adapt, evolve and update to remain effective.

Content Disarm and Reconstruction or CDR, works by regenerating all incoming files and documents. It begins by deconstructing them, repairing or removing elements that do not match the file type standards or the organisation’s risk policy. It then rebuilds the files into a clean, safe and visually identical version that can be received or sent on. CDR provides an additional layer of cyber-defence and content protection, and is so impressive that Gartner expects the technology will “ultimately be considered a best practice.” to “eliminate one the of the most common infection vectors that is hard to deal with in other ways.”

"CDR will ultimately be
considered a best practice."

This is How We Do it

deep-File Inspection

deep-File Inspection breaks down the entire file and validates it against the format’s specification.


All deviations uncovered during the inspection are remediated back into line with the file standard.


Sanitisation removes high-risk Active Content such as macros, JavaScript, URLs and embedded files.
