Acoustic agents are rapidly advancing in production. But most teams have no way to enforce what their agents should and shouldn’t say, especially when users actively try to push past system instructions.
ElevenAgents Guardrails 2.0 There is a redesigned security layer that validates user input and agent responses in real-time, before anything reaches the end user.
Agents have long conversations. System indicators are not under pressure. One wrong answer in healthcare or banking quickly breaks trust. Guardrails 2.0 gives teams three independent enforcement layers: system prompt hardening, user input validation, and agent response validation. Custom guardrails let you define policies in natural language and automatically enforce them on every call.
What makes it interesting:
🔒 Custom rules run as an independent parallel check, not a filter on the main model.
🎯 Prebuilt protections for focus, content protection, and quick injection
⚙️ Execution modes are designed for acoustic latency trade-offs.
🚪 Configurable exit strategy when guardrail fires
📋 Improved chat history for compliance-sensitive deployments
Built for enterprise teams deploying voice agents in regulated industries: healthcare, banking, and retail.
Note: Currently in alpha. Reduction and Zero Retention Mode are Enterprise tiers.
If you’re moving voice agents from pilot to production, it’s the infrastructure layer that makes it viable.
