I'm on Checkpoint R77.20 and Paloalto Pan OS 6.1.x on a daily basis, and pfSense of course!
Actually to followup on my earlier post, one neat feature that I've seen on Checkpoint is a rule expiry field. They already have schedule like time conditions, but the expiry field just basically completely disables the rule after a certain date.
Again, great for audit compliance, would be cool to have that AND a feature that cleans up expired rules after an amount of time, and a flag to mark it as do not delete in the case of a rule that needs to be enabled from time to time but only for a certain amount of time, like remote support via SSH type of thing.
