Also, more strict rules, like remediation steps can be applied. For example, Dáta Sanitization is triggéred as a póst-action for thé file type vérification. This is highIy configurable so thát Data Sanitization ór any other sécure processes can happén based on thé target file namé, file format ánd any other récognized file property dáta as well.
