TL;DR: Braintrust handles prompt testing, dataset evaluation, and trace-based observability, but the article says regulated production teams need runtime blocking, automated compliance mapping, and broader multimodal test coverage that evaluation-only workflows do not provide, according to Openlayer. The practical issue is that logging model behaviour is not the same as enforcing policy before sensitive outputs or unsafe actions reach users.

By the numbers:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities , 46% confirmed, 26% suspected.
Questions worth separating out
Q: How should security teams govern AI systems that need both evaluation and runtime control?
A: Use evaluation to validate quality before deployment, but require runtime controls to block unsafe prompts, outputs, and tool calls once the system is live.
Q: Why do AI agents create governance problems that normal access reviews miss?
A: AI agents can read, copy, transform, and re-share data after the original access decision, so a static review of entitlements does not capture downstream impact.
Q: What do organisations get wrong about compliance in AI evaluation platforms?
A: They often assume trace logs and test results are enough for audit readiness.
Practitioner guidance
- Separate evaluation from enforcement Use prompt testing, dataset scoring, and version control for pre-production validation, then add runtime blocking for prompt injection, unsafe tool calls, and PII leakage in live workflows.
- Map AI workflows to control ownership Assign accountable owners for prompts, models, tools, and deployment pipelines so that every high-risk action has a clear approval and review path.
- Automate audit evidence capture Build compliance evidence collection into the AI lifecycle so test results, policy decisions, monitoring events, and exceptions are retained without manual reconstruction.

Evaluation-only AI governance creates a false sense of control. Trace collection, scoring, and dataset testing are useful, but they do not stop a model from leaking data or following injected instructions once it is connected to real users and tools. The governance failure is treating observability as protection. For production AI, security teams need controls that act at execution time, not just after the fact.
A question worth separating out:
Q: Should regulated enterprises choose runtime guardrails before expanding AI deployment?
A: Yes, if the system can process sensitive data, interact with external tools, or influence operational decisions. Runtime guardrails reduce the chance that unsafe content, injected instructions, or disallowed actions reach users or downstream systems. Evaluation still matters, but it should support deployment decisions rather than stand in for active protection.
