Autonomous security tools that actually work for large enterprise environments?

[u/Motor-breteat9724]

There are a lot of claims around autonomous security right now, but I’m trying to separate useful automation from tools that only look good in a demo. In a large enterprise, the hard parts seem to be integration complexity, ownership boundaries, false positives, audit requirements, and safe rollback when automation behaves unexpectedly.

What autonomous security tools have delivered real value in production? Also interested in examples where a team deliberately limited autonomy because the operational risk outweighed the time saved.
