ElevenAgents Guardrails 2.0 is a safety layer built on top of ElevenLabs' voice agent platform, designed for enterprises deploying customer-facing AI voice agents at scale. The core problem it solves: voice agents in production tend to drift, get manipulated through prompt injection, or go off-brand in ways that only surface after something embarrassing happens. Version 2.0 adds three main capabilities: real-time policy enforcement that monitors agent behavior as it happens, prompt injection protection against users trying to manipulate the agent's instructions, and configurable custom rules that enterprises can tailor to their specific compliance or brand requirements. Unlike static guardrails baked into the system prompt, these operate as a live enforcement layer during conversations. The timing matters. As more enterprises put voice agents on their phone lines and websites, the "what could go wrong" list has gotten longer — agents giving wrong pricing, going off-script with sensitive customers, or being jailbroken into saying things they shouldn't. Guardrails 2.0 positions ElevenLabs not just as a voice synthesis platform but as an enterprise-safe agent runtime.

Mozilla's AI security team — 0DIN (Zero Day Investigation Network) — open-sourced their internal LLM vulnerability scanner on April 10, 2026. Unlike synthetic red-teaming tools, this is built on real attack knowledge: 0DIN researchers have spent two years getting paid to break every major frontier model, discovering and reporting thousands of verified vulnerabilities. Those discoveries are now encoded as reproducible probes. Built on NVIDIA's GARAK open-source framework, the 0DIN Scanner adds a graphical interface, automated scan scheduling, cross-model comparative analysis, and enterprise reporting. It ships with 179 community probes covering 35 vulnerability families — prompt injection, jailbreaks, data leakage, harmful content generation, and more — all aligned to the OWASP LLM Top 10. Six specialty probes target advanced threat categories. For any team deploying LLMs in production — RAG systems, agents with tool access, customer-facing chatbots — this is now the baseline for security auditing. The Apache 2.0 license means enterprise deployment without legal headaches. With LLM security audits running $50K-$200K from specialist firms, this democratizes access to professional-grade testing.
Reviewer scorecard
“Static system prompt guardrails are a band-aid. Having a live enforcement layer that can catch drift and injection attempts as they happen is the right architecture for anything customer-facing. This is the kind of tooling that makes it reasonable to deploy voice agents in sensitive contexts like healthcare or finance.”
“Every team shipping LLM features in production should be running this in CI. The OWASP LLM Top 10 alignment means it maps directly to compliance frameworks. The fact that it's built from actual vulnerabilities found in frontier models — not synthetic prompts — gives it way more credibility than competitors.”
“Guardrails as a paid add-on to your voice agent platform is a strange model — safety shouldn't be upsold. Also, ElevenLabs controlling both the voice synthesis and the safety layer means there's no independent verification that the guardrails are actually working. That's a dangerous single point of trust for enterprise compliance purposes.”
“GARAK-based scanners catch known vulnerability patterns, but novel attacks will always slip through static probe libraries. The graphical interface is serviceable but not polished enough for non-technical security teams. And 179 probes sounds like a lot until you realize a dedicated red teamer generates thousands of custom vectors in a day.”
“Voice agents are the new customer service reps, and companies are learning the hard way that they need guardrails. This is the beginning of a whole category: real-time behavioral safety systems for AI agents. The team that solves this at scale — across providers, not just ElevenLabs — will be enormous.”
“As LLM agents gain tool access and real-world power, security becomes existential not optional. Mozilla's decision to open-source two years of hard-won attack knowledge is a rare act of public benefit in a space dominated by consulting firms charging enterprise rates. This becomes the industry standard within 12 months.”
“Brand safety for voice is genuinely underserved. Written AI outputs can be reviewed and filtered; voice interactions happen in real time with no undo. Knowing your agent won't say something off-brand to a live customer is worth paying for, especially for high-volume contact centers.”
“Even content teams using AI for copywriting or customer service need to know their models won't be jailbroken into producing harmful outputs. This gives non-technical managers a report they can actually present to legal. That's underrated value.”
