Vectra AI got there first, launching in 2012 — that's 1 year of extra runway. SentinelOne didn't arrive until 2013. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

SentinelOne has about 2800 employees; Vectra AI has about 650. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both SentinelOne and Vectra AI compete in AI Security, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
