AI Guardrails

AI guardrails are the rules and technical controls that constrain what an AI agent may say or do: blocked topics, banned phrases, output filters, action restrictions, and rate limits.

They operate automatically on every interaction, unlike human review, which samples or escalates selectively.

A practical example

Example: a sales assistant agent is configured to refuse pricing commitments, never mention competitors, and block any output containing personally identifiable information before it is sent.

What to evaluate before investing

  • Ask which guardrails are configurable by you versus fixed by the vendor, and whether new rules take effect immediately.
  • Test the guardrails yourself with adversarial prompts during the trial, not just the vendor's demo script.
  • Check whether blocked outputs are logged with the reason, so you can tune rules based on real violations.

Limitations and tradeoffs

Guardrails reduce but do not eliminate failure modes; determined prompt manipulation or unusual inputs can still produce unwanted outputs.
