Abnormal Security got there first, launching in 2018 — that's 1 year of extra runway. Orca Security didn't arrive until 2019. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

Abnormal Security has about 650 employees; Orca Security has about 450. 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 Abnormal Security and Orca Security compete in AI Security, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
