I use it... at first it was ok, then it had some issues, but now it has really started to move forward. The Real Time Search is a big differentiator IMO, as well as the remediation capabilities (anything you can script you can do, plus the built-in stuff). They have made a lot of progress on the visibility and detection front, which is solid. Pairing it with Expert Rules in ENS gives a very strong security posture.
