Question

Blocked keywords not blocked in some browsers

I've currently got the Fortigate 1500D on 5.6.2.  I am testing out using SSL Deep packet inspection and it's working very well for the most part.

 

I'm running into an issue blocking keywords on google searches.  If I search for one of the keywords "hoe" in internet explorer it's blocked right away as a blocked keyword.  On this same machine if I search using Edge or Chrome browser I am getting results, no block at all.  I checked and all of the browsers are showing the SSL certificate for the fortigate.  

 

On the same chrome browser when I try this on yahoo.com the blocks are working normally.  QUIC should be blocked by both a service policy that blocks UDP 443 and UDP 80, as well as being blocked in the application policy.

 

Any thoughts on what I could be missing here?  I appreciate any thoughts!

    Hello ddevore9,

     

    Did you set all the Google.Search_* signatures to Block too? You need to set all of them to Block to block Google's search.

    Are you blocking TEREDO along with QUIC?

    I just tried blocking TEREDO and it does not seem to help.  It's got to be some protocol (like quic or teredo) that's allowing chrome/edge to get past the blocks.
