If the zip file is not password protected, MEG can do content scanning and file filtering inside of archives. So if you have created a file filter rule for .js files, it will grab them from inside zip files.
Thanks for the response, I though so that the email file filtering policy would check for .js or .exe files in zip archives, however on my case there is a policy in place, however the .js and .exe files are getting through so some reason. Not sure whats wrong there.
Are you able to please guide me on how the policy should be set as.
