Guardrails

Detect and prevent prohibited topics in agent output and user input using built-in content guardrails.

Guardrails are a built-in content moderation layer that checks agent responses and user messages for prohibited topics. When a guardrail triggers, the prohibited content is automatically replaced with a safe placeholder message, keeping the call going without interruption.

How Guardrails Work

Guardrails apply in two ways:

• Output guardrails — check what the agent says. If the response contains a prohibited topic, it is replaced with a placeholder before being spoken.
• Input guardrails — check what the user says. If the user’s message contains a prohibited topic, the agent responds with a placeholder instead of processing the request.

In both cases, the call continues normally after the placeholder is delivered. Guardrails do not end the call, transfer the call, or trigger any other action — they only replace the problematic message.

Configuring Guardrails

Configure guardrails when creating or updating an agent via the dashboard or API. In the dashboard, guardrail settings are under Security & Fallback Settings.

Guardrails add approximately 50ms of latency to calls.
