Dynamic URL filtering???

L2 Linker

What is it exactly -  and is it recommended? I've seen some posts here that indicate turning it off solved some poor performance issues. I guess I'm asking whether I should turn this feature on and what will it buy me?

Ver 3.1.4 PA 2020

As for the feature -

When a URL category cannot be determined using the local database, dynamic URL filtering  will send all  URL unknown category  to BrightCloud server in the cloud for resolution in real time. The response is then cached in the dataplane. The response from the brightcloud server will be stored in the local cache for 7 days.

I can't say I've noticed it impacting performance unless the daemon/service died which we had happen a few times - though this seems to have been fixed in one of the recent PAN OS 3.1.x releases.

I don't know how quickly Brightcloud respond to zero days threats/websites but in theory dynamic filtering is incredibly useful.
