The problem
Evals catch failures before release. Production still surprises you: new phrasing, new documents, new attacks.
What Signa does
Guardrails run between your agent and the user. Each check is a small, fast model trained on your policies, and each block is logged with its reason and trace.
Teams start in monitor mode, see what would have been blocked, and switch to enforce when the false-positive rate is where they want it.
Closing the loop
Every blocked or flagged response can be promoted into an eval case in one click, so the next release is tested against it.
