File Cleaning for OneDrive and SharePoint

File cleaning (Threat Extraction) uses a Content Disarm and Reconstruction (CDR) engine as an additional layer of security alongside the Anti-Malware engine to prevent malware attacks and their spread among internal users.

The system scans every file uploaded to or edited in Office 365 OneDrive or SharePoint.

• If malware is detected, Avanan applies the malware workflow.

• If no malware is found, it sanitizes the file by removing active components that may conceal undetected threats.

If required, administrators can restore the original file to ensure business continuity.
