About File Type Controls for Internet Access
In a Security profile, configure the file type controls for files on internet destinations. You can choose whether to control the upload, download, or upload and download of certain types of files. Then, add the Security Profile for internet access to the internet access rules in the Access policy.
If File Type Blocking is enabled and a user device attempts to download or upload a selected file type from an internet destination, Secure Access presents a Block page instead of the requested resource.
Note: Blocking some file types may cause a website not to display correctly.
