Blocking executable file uploads
To block the upload of executable files, click Advanced Options. Under Executable File Uploads, select Block executable file uploads. This setting blocks the upload of all executable files across your organization.
You can enable analysis of inbound executables on the Web Content & Security tab. See Configuring file analysis. To block the download of executable files, see Blocking by file type.
Important: Executable files included in archived/compressed files are not blocked. Archived/ compressed files are inspected for malware but are not extracted to determine if the contents
contain an executable file that should be blocked. Archived and compressed files can be blocked, if needed, to avoid uploading an unwanted executable file.
