Protecting Open-ended Text Interfaces
to Intelligent Systems
The Audn Browser Extension protects your browser's AI with the world's largest attack corpus, generated by Pingu-Unchained-1. It detects jailbreaks, prompt-injection and covert exfiltration channels before attackers can.
We don't just stop bad actors; we stop bad AI agents too, because we built the best one.
Works in any Chrome-based AI browsers & runtimes

The Lethal Trifecta for AI Agents
If your Large Language Model (LLM) tools – a.k.a. “AI agents” – combine these three capabilities, an attacker can trick them into leaking sensitive data:
- Access to private data – the very reason you gave the tool access in the first place.
- Exposure to untrusted content – any attacker-controlled text or images routed to the model.
- Ability to externally communicate – exfiltrating your data once compromised.
Audn neutralises each side of this triangle:
MCP Gateway Firewall
All outbound data is routed through our secure MCP gateway where information-physics analysis blocks deterministic leaks before they leave your browser.
Untrusted Content Firewall
Our extension continuously scans every webpage, detecting prompt injections and covert exfiltration vectors in real time to shield your agents.
Communication Governance
Browsers and agents love to talk; we enforce strict egress policies and cryptographic tagging so only vetted channels are allowed.
The Enterprise Browser Extension
Productivity, access, and security: built directly into the browser. Welcome to the next chapter of the modern enterprise workspace.
Deliver secure, seamless AI assisted web access
Enterprise-grade browser security without compromising on user experience.
Stop Prompt Injection
Automatically detects and blocks prompt injection attempts before they reach your AI systems.
Block Jailbreaks
Real-time detection of jailbreak attempts, social engineering, and manipulation tactics.
Covert Exfiltration Defense
Prevents data leakage through hidden channels and obfuscated payloads in AI responses.
Full Visibility
Complete audit trail of all AI interactions across your organization's web browsing.
Zero Friction
Install in minutes. Scans any website or SaaS or internal web app in real-time while browsing.
Enterprise Ready
SOC 2 compliant. SAML SSO. Role-based access. Built for security teams at scale.
Ransomware Detection
Identifies and neutralizes malicious downloads & scripts that aim to encrypt or extort your data.
Shadow AI Visibility & Control
Track and govern shadow AI extension installations. Observe usage, enforce approvals, and block unapproved tools before they touch sensitive data.
Detection Mathematics
Audn employs physical information theory and post-quantum cryptography research, building on concepts like Shannon Entropy and lattice-based signatures, to detect and block jailbreak attempts with provable guarantees.
Entropy Spike Rule: if the token-level entropy H(X) relative to verified ground truth exceeds the safety threshold τsafe, Audn triggers a circuit-break and blocks the request.
Coprime-Factor Safety: content sources are mapped to orthogonal roots; correlated failures (GCD > 1) are rejected to prevent monoculture exploitation.

Powered by Pingu-Unchained-1
Our browser extension checks website content against the same attack corpus that powers our adversarial AI. Our attack corpus is the biggest in the world, containing over 10,000 unique attack patterns trained to break open-ended voice and text AI systems. We generated it using our proprietary Pingu-Unchained-1 malicious LLM model. This ensures that your browser is protected from the similar attacks and risks that our AI constantly grows and evolves with.
