How CDR instantly removes risk


the file’s digital DNA


to known good standard


risky content by policy


safe, visually identical file

Step 1 – Inspect

Three layers of the file are inspected to validate its digital DNA complies with the known good manufacturer’s specification. Remediation instantly takes place where deviations are found.

Step 2 – Rebuild

The file is rebuilt to its known good manufacturer’s standard, ensuring the file is clean and threat-free.

Step 3 – Clean

High risk active content (i.e. macros and embedded links) is cleaned and removed, based on company policy – so only the users who need active content receive it.

Step 4 – Deliver

The user instantly receives a safe, identical file that’s compliant, standardized and trusted – reducing risk while maintaining business continuity.
