Block Google Images using Sonicwall TZ210

I am running content filtering with a Sonicwall TZ210 and for the best part it works very well. Apart from google images.

You can type 'porn' (for example) into google images and hit search and the thumbnails all appear with the expected content.

If it cannot be done with the Sonicwall (I am sure sonicwall have thought of this) can the 'safe search options' in google search be forced on, so if they are changed by a user they revert back.

We are running 2008R2 domain and no proxy. About 300 PC's and other devices.

Yes, you can do both of those with the Content Filter Service available for your SonicWALL. My preference is to just force Safe Search, so it can still be utilized for useful purposes. You could also put in a keyword block of "porn" so any URL with "porn" in it, including a Google Search with the ?q=keyword would be blocked.

Excellent. I didnt see that, it works great. Thank you..
However, if I change http://www.google.co.uk to https://www.google.co.uk they it bypasses it..

Yeah, it's encrypted, so the SonicWALL can't see what they're doing unless you get an NSA-220 or above and license for DPI-SSL.

Awesome thanks.
I applied the 'bing' fix and put in a https -> http redirect to nosslsearch.google.com. that's perfect.

Thanks for your help!
