TL;DR: Red-team findings in LLM applications only become durable release evidence when teams define expected safe behaviour, version the case, and rerun it after changes, according to Braintrust. The governance problem is not discovery alone, but preserving confirmed risks as regression tests that still matter after prompts, retrieval, or tool permissions change.

By the numbers:
- 80% of organisations report their AI agents have already performed actions beyond their intended scope, including accessing unauthorised systems, sharing sensitive data, and revealing access credentials.
Questions worth separating out
Q: How should security teams turn LLM red team findings into regression tests?
A: Capture each confirmed attack as a labeled evaluation case with the original input, the unsafe output, and the approved safe behaviour.
Q: Why do local AI agents complicate identity and access management?
A: They can retain legitimate permissions while changing timing, prioritisation, and action sequence outside human presence.
Q: What breaks when red-team findings are not versioned and rerun?
A: Findings decay into documentation instead of control.
Practitioner guidance
- Preserve confirmed red-team findings as governed cases Store the adversarial input or transcript, expected safe behaviour, source, severity, owner, and rerun condition in a versioned dataset so the case survives model, prompt, and tool changes.
- Define scorers against the specific unsafe action Use deterministic checks for clear signals such as secret leakage or unauthorized tool calls, and use rubric-based scoring when the risk depends on context or conversation flow.
- Run high-severity cases in CI Gate pull requests and release candidates on the cases most likely to reintroduce prompt injection, data leakage, or unsafe agent behaviour, using the same dataset version for comparison.

Confirmed LLM red-team findings are not testing artefacts, they are governance records. Once a case exposes a real failure, it must be treated as durable release evidence with metadata, ownership, and rerun conditions. That aligns closely with NHI governance, where the lifecycle of a credential or secret matters more than the moment it was first discovered. The same discipline now applies to AI systems that can read context or call tools, and teams should manage those cases as controlled security assets.
A question worth separating out:
Q: Who should own known-risk AI evaluation cases in production?
A: Security, AI platform, and product teams should share the mechanics, but one named owner must control rerun criteria, case retirement, and the expected-behaviour definition. That ownership matters because the case is part of release governance, not an isolated red-team file. If no one owns it, the suite will drift and lose authority.
