Gateman - AI Data Loss Prevention

Prevent data leaks to AI tools. Detects and blocks secrets, API keys, and PII before sending to ChatGPT, Claude, etc.

The AI Revolution Demands New Security. Your team is already leveraging AI tools like ChatGPT, Claude, and Copilot. But are you confident sensitive company data—like API keys, source code, customer PII, or internal documents—isn't accidentally being exposed? Traditional DLP fails at the browser edge, leaving your organization vulnerable to costly data breaches and compliance violations. Gateman is the essential browser extension for safe AI adoption. We provide real-time, on-device data loss prevention (DLP) specifically designed for generative AI. Gateman intercepts and analyzes content before it leaves your employees' browsers, ensuring your most critical data stays secure. Why Gateman is Your AI Security Imperative: Unrivaled Privacy: All checks run locally on the user's device. Your prompts and sensitive data never leave your browser and are never stored by Gateman.

Universal Coverage: Works seamlessly across all major AI platforms (ChatGPT, Claude, Gemini, Copilot, and more) directly within your browser. Zero Friction: Designed to be lightweight and performant, Gateman operates silently in the background, only intervening when a policy violation is detected. No slowdowns, just smarter security.
