Once you have SSL decryption configured, you can follow following documents: 1. https://live.paloaltonetworks.com/videos/1332 (Video Demonstration of Google SafeSearch Custom App ID) 2. https://live.paloaltonetworks.com/docs/DOC-1399 (How To Control Image SafeSearch for Google and Bing) You can block following app-ids from "Google-SafeSearch-Strict-4.1" : 1. google-image-search-moderate 2. google-image-search-ss-off 3. google-safesearch-set-moderate 4. google-safesearch-set-off When users go to http://google.com or https://google.com (ssl decryption required), they can search for any keyword. When they click on Images, they will get a application block response page (Device -> Response Page -> Application Block Page). You can edit this page to guide them to change the setting to SafeSearch option . Once safesearch is enabled, they can access the image search. Hope that helps.
