# Safety and Data Protection

  Guardrails are project policies the gateway enforces inline: on the way in (prompts) and on the way out (responses). Each policy is a collection of rules; each rule is a check type scored by a provider. [About guardrails](/agent-router-enterprise/guides/operate-and-govern/safety-and-data-protection/about-guardrails/) explains that model and how evaluation works; the guides that follow cover configuring guardrails and providers, redacting sensitive data, blocking prompt injection, applying stricter policy bundles to coding-assistant traffic, and the developer-side view of blocked and redacted requests.
