Every AI governance tools demo catches basic injection and shows a pretty dashboard. Am looking for one that can handle advanced multi turn prompt injection

Compliance dropped a mandate on us last week. We have like 8 ai features shipping in q3 and they want governance locked down before anything goes live. For contxt, we're ~2k people, mostly on openai right now but they know that might change. The thing they're obsessed with is multiturn prompt injection. last quarter a test user slowly extracted internal data over like 15 messages and our current safety layer caught noneo of it because each individual message looked clean.
