ZIA Policy - user enforcement

Hello Community,
How long does it take for a change in a ZIA Policy to be enforce on the final user?
Lets say I blocked Facebook (It was previously allowed) and I activate the chnage on the portal.

Will Facebook be automatically blocked for the user? Do they need to restart the PC? If not how long does it take?


Hello Xavier,

enforcing URL blocks via ZIA only takes some seconds after “activation” and is automatically applied to the selected user/groups/locations/etc in the URL Filter policy. As these policies are enforced on ZIA PSE (formerly known as “Zscaler Enforcement Nodes”) there is no need to reboot clients. Please also take a look here.


Thanks a lot Manuel for the clarification, and thanks for your time as well !!!
