What it is

Voice agents drift, get manipulated, or go off-brand in production. Guardrails 2.0 adds real-time policy enforcement, prompt injection protection, and custom rules to ElevenAgents. For enterprise teams deploying agents at scale.

Intent

I need it when

Maintain compliance and audit trails by redacting sensitive data from transcripts and recordings after calls end

Conversation History Redaction automatically strips personally identifiable information, payment card numbers, and other sensitive entities from transcripts and audio, replacing them with placeholders while preserving analytics and QA data. Available to enterprise customers alongside Zero Retention Mode.

Ensure agent responses comply with content policies and avoid sensitive material (violence, explicit content, political sensitivity)

Content Guardrails screen agent responses for multiple categories of unsafe content with tunable sensitivity thresholds, allowing you to tighten enforcement for high-risk use cases or loosen it to reduce false positives.

Block prompt injection attacks and adversarial user inputs before the agent responds

Manipulation Guardrails detect and terminate conversations that contain prompt injection or instruction override attempts, providing a security layer that validates user input before agent processing.

Enforce domain-specific business policies (e.g., no financial advice, no unauthorized refunds) automatically across all agent calls

Custom Guardrails let you define policies in natural language and evaluate every agent response against them in real-time. Violations trigger configurable exit strategies (end call, retry with corrective feedback, or transfer to human).

Prevent AI voice agents from drifting off-topic or violating brand guidelines during long customer conversations

Focus Guardrail reinforces system prompt instructions throughout multi-turn conversations, keeping agent responses directed and consistent with defined goals. Especially useful when agents are under pressure or users attempt to manipulate behavior.

Drop

Not a fit when

When you need real-time guardrails with zero latency tolerance—streaming mode can deliver up to 500ms of audio before blocking in voice agents
When you require deterministic, fully predictable agent behavior—guardrails are designed for non-deterministic LLM systems and cannot guarantee 100% prevention of all edge cases
When you operate simple, single-turn interactions with no conversation history—guardrails are optimized for long, complex conversations where agent drift is most likely
When you need guardrails for non-voice modalities like image/video generation—Guardrails 2.0 is designed specifically for ElevenAgents voice agents
When you cannot accept any latency overhead—blocking mode adds 200–500ms extra latency; streaming mode is required for near-zero delay but allows partial audio delivery before interception
