Fortiguard Intrusion prevention - access blocked

Hello @kamal1,

Please check if the action for the category 'search engines and portals'  in the web filter profile set to block.

Or

If you are using proxy-based inspection mode, try changing it to flow mode and have a check.

Hello Kamal1,

Most of the times the Username & Group Name are retrieved from FSSO config on your Fortigate, so if it is a local user then most probably it will return blank values. Kindly check the policy details & the UTM filters applied to it to narrow down the issue. Also, forward traffic log will help in identifying the source IP of the user for this traffic.
