AI Guardrails

Controls that constrain what a model or agent can receive or produce at runtime - blocking unsafe inputs and outputs as they happen.

Guardrails are runtime checks applied to prompts and responses: blocking prompt injection, stopping sensitive data from leaving, filtering disallowed content, and validating that output matches an expected shape.

They differ from offline evaluation: guardrails act inline on live traffic, while eval suites measure model quality in testing. Production systems need both.
