In some use cases, the sanitized file can't be used dues to an integrity check. We recommend to block file based on objects to prevent zero-day attack. To configure this feature, please follow these steps
- Workflow Manageement > Workflows > Workflow name > Advanced > Enable Block file if containing
- Enable the Object types you want to block and which file families should be blocked

If a file contains the blocked objects, MetaDefender Core will block the file with a new verdict - Blocked Verdict by Deep CDR - an example JSON result
