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.

How to Perform Deep CDR on Files
In the UI, please make sure to enable "Deep CDR" on the advanced scanning menu:
Data Sanitization (CDR) APIs
We offer a REST API for data sanitization (CDR) to allow users to incorporate the technology's capabilities into their own solutions.
Visit [MetaDefender Cloud API v4](/v-4/metadefender-cloud-api-v4/ref#Data Sanitization Cdr) to learn more about this API.
Private Deep CDR
Whether uploading files in private mode or not the sanitized version of the file will be deleted after 24h.
Deep CDR Configuration - Advance settings
The table below explains how Deep CDR is configured on MetaDefender Cloud. This configuration is standard for all users and cannot be adapted to specific user needs.
Deep CDR is configured to keep the format of the original file (e.g: sanitized versions of PDFs will also be PDFs, we won’t convert them to images or any other format)
