Data Sanitization on MetaDefender Cloud

MetaDefender Cloud Deep CDR

Data sanitization, also known as Deep Content Disarm and Reconstruction (CDR), is the process of breaking down a file, removing exploitable content, and then reconstructing the file with all original content and functionality restored. This process renders files safe by stripping potentially malicious or insecure content – macros and hyperlinks, for example.

How It Works

MetaDefender Cloud sanitizes files after first scanning them for malware with 20+ anti-malware engines. After multiscanning is complete, MetaDefender Cloud creates a sanitized version of every file. The sanitized file is available for immediate download. To download the file, click "Sanitized File" above the displayed multiscanning results, then click "Download Sanitized."

Data sanitization (CDR) does not modify or alter the content within a file. It simply removes the exploitable objects within the file.

Our data sanitization (CDR) technology supports over 150 file types including common file types such as DOC(X), XLS (X), PPT(X), and PDF, and we are always adding more in order to expand the protection afforded by data sanitization.

The Deep CDR engine is always the latest version on MetaDefender Cloud. The engine configuration is standard and no file conversion is performed.
