Of course if you let an ML-powered "anomaly detection" engine run rampant on your logs, it's going to find anomalies...just like if you hire a ghost hunter, you'll be informed that your house is haunted. In the end, ghost chasing is all this anomaly nonsense turns out to be-- the justifications for conclusions by ML practitioners and ghost hunters alike tend to be equally mumbly and hand-wavy.
Me working from home is technically an anomaly, and one these systems are all too eager to flag. We get random logins from overseas VPSes-- it's an anomaly! Oh, wait, no, we onboarded a client application. Oh, look, a random login from China for a US-based employee with no history of foreign logins! Yeah, that guy just started in a new position with travel requirements. Hey, this IP just tried to log into 5000 user accounts! Congratulations, you just alerted me to the existence of carrier NAT.
None of this saves any time and usually wastes it, since it stirs up paranoia where none was otherwise warranted. It's a fun toy that gives the appearance of being productive when all it's actually doing is generating literally endless busywork. Good for justifying your SOC budget I suppose.
But in the end nobody wants to pay a quarter-million dollars for a black box that just sits there quietly-- if it's not constantly drawing attention to itself and all the badness it's pretending to find, you're not going to have any reason to renew the license.
"Renew it? Why? This thing didn't find anything at all last year."
