About Gateman - AI Data Loss Prevention

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. This is true on-device DLP. Proactive Protection: Instantly blocks critical secrets (API keys, credentials) and provides actionable warnings for high-risk data (source code, PII) before it's sent to any AI tool. 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. Empower Your Team: Enable your employees to use AI tools confidently and productively, knowing your company's intellectual property and customer data are protected. Audit-Ready: Centralized admin dashboard (available on web) provides visibility into policy violations and enforcement actions, ensuring compliance and accountability. Gateman doesn't restrict AI; it secures it. Give your team the freedom to innovate with AI, backed by enterprise-grade data protection. Install Gateman today and transform your AI usage from a risk to a competitive advantage.
