ElevenAgents Guardrails
Real-time guardrails that stop prompt injection, content violations, and drift in ElevenLabs voice agents.
The most practical real-time guardrail system currently available for voice agents, with genuinely useful granularity and enterprise-grade data controls. Alpha status is a real caveat, as are the notable platform fees—you'll pay $299+/mo for Scale tier plus usage. Teams already on ElevenLabs should absolutely enable it; others should weigh the cost and platform lock-in against standalone options.

Skip ElevenAgents Guardrails if you are not using ElevenAgents (no integration with other voice platforms), if your call volumes are low enough that manual review suffices, or if you're a hobbyist without production safety needs.
You need at least the Scale tier ($299/mo) for team collaboration and 3 workspace seats, which may be overkill for small teams.
Guardrails 2.0 is included with ElevenAgents plans, which start at $0/mo (Free) and scale to $6 (Starter), $22 (Creator), $99 (Pro), $299 (Scale), $990 (Business), and custom Enterprise. For teams already paying for ElevenAgents, Guardrails adds safety without extra cost. Compared to standalone moderation services (e.g., OpenAI Moderation at $0.01/1K tokens), the platform fee is significant, but you get integrated voice-specific guardrails.
In short
ElevenAgents Guardrails — Real-time guardrails that stop prompt injection, content violations, and drift in ElevenLabs voice agents. Best for Enterprise teams deploying voice agents at scale in customer support, Sales teams using voice agents for outbound and inbound calls, Marketing teams using agents for brand-safe customer interactions.

About ElevenAgents Guardrails
ElevenAgents Guardrails 2.0 is the redesigned control layer inside ElevenLabs' voice agent platform, protecting every call from prompt injection, content violations, and system-prompt drift. It's built for teams that deploy voice agents at scale in customer support, sales, and other high-stakes workflows where safety and compliance are non-negotiable. The system works on three levels: Focus Guardrail reinforces the system prompt during long conversations, Manipulation Guardrails detect and block social engineering and injection attempts (and can terminate risky calls), and Content and Custom Guardrails screen every agent response before delivery. Custom Guardrails let you define your own domain-specific policies in natural language, enforced by a lightweight model that runs in parallel with response generation, returning block or allow decisions with minimal latency. You get granular control: execution modes to balance real-time speed against strictness, exit strategies (end, transfer, escalate, retry), per-category sensitivity thresholds, and per-agent configuration. Every trigger is logged to conversation analytics, so you can refine policies over time. For enterprise clients, conversation history redaction strips sensitive entities from transcripts, recordings, and webhook payloads, replacing text with placeholders and audio with bleeps, plus Zero Retention Mode for compliance. Guardrails 2.0 is now in alpha within ElevenAgents, configurable via the Security tab or API. It's positioned as part of a broader trust and safety foundation that supports AIUC-1 certification and agent insurance. Unlike standalone moderation services, this is integrated into the ElevenLabs ecosystem, which also offers text-to-speech, speech-to-text, and other voice capabilities, so you can build and deploy complete voice agents with built-in safety.
Behind the Verdict
Guardrails 2.0 is a substantial upgrade from the earlier iteration, offering a layered defense that tackles the biggest failure modes of production voice agents: drift, injection, and policy violations. The Focus Guardrail is a smart addition for long conversations where agents tend to wander off-topic. Manipulation Guardrails give you a safety net against prompt injection, a real threat in customer-facing deployments. Content Guardrails with tunable thresholds let you fine-tune sensitivity per category, balancing safety with user experience. Custom Guardrails are the standout: define your own rules in natural language and have a parallel model enforce them without degrading latency. The granular control is refreshing—you can run guardrails alongside response generation for near-zero delay or hold responses until fully cleared. Exit strategies (end, transfer, escalate, retry) give you flexibility in how you handle violations. Per-agent configuration means you can have different guardrail profiles for different use cases. On the downside, Guardrails 2.0 is still in alpha, so expect rough edges and changes. The pricing is steep for smaller teams: you'll need at least the Scale tier ($299/mo) for team collaboration, and usage credits add up. Enterprise features like Zero Retention Mode and conversation history redaction are locked behind custom pricing. If you're not already on ElevenAgents, the lock-in is significant—you can't use Guardrails with other voice agent platforms. Where it fits: teams already using ElevenAgents that need real-time safety, especially in regulated industries. Where it doesn't: hobbyists or low-volume use cases where manual review suffices, and teams committed to other voice platforms.

Real-world workflow fit
Concrete scenarios for the personas ElevenAgents Guardrails actually fits — and what changes day-one when you adopt it.
Deploying a voice agent for financial advice and need to ensure no prohibited advice is given.
Outcome: Create a Custom Guardrail that blocks responses containing financial advice, set content sensitivity to high, and configure exit strategy to escalate to a human. Every trigger is logged for audit.
Building a sales agent and concerned about prompt injection attempts from users.
Outcome: Enable Manipulation Guardrails to detect and terminate risky calls, and run guardrails alongside response generation to minimize latency. Use the API to configure per-agent settings programmatically.
Running a high-volume support agent that needs to stay on-brand and avoid harmful responses.
Outcome: Enable Focus Guardrail to keep the agent on script, Content Guardrails to block unsafe content, and use conversation analytics to refine the system prompt over time.
Use Cases
- Deploy a customer support voice agent with automatic blocking of harmful or off-brand responses before delivery.
- Protect a sales agent from prompt injection attempts by users trying to extract sensitive data or override instructions.
- Enforce custom compliance policies (e.g., no financial advice) on every call without modifying the agent's system prompt.
- Monitor and redact conversation history to remove PII or sensitive content after calls are completed.
- Define natural language guardrails that reduce escalations and compliance review cycles in regulated industries.
