Browser Agents

Browser Agents

Browser agents are AI assistants accessed directly through a web browser — ChatGPT, Claude.ai, Microsoft Copilot, Google Gemini, Perplexity, and similar platforms. Enterprise employees use these directly, bypassing any server-side gateway. The threat surface is the browser itself: what employees paste in, what data leaves via fetch or XHR, and what content can be injected into the AI session.

Highflame Browser Security deploys as a managed browser extension across Chrome, Firefox, Safari, and Edge. It intercepts browser APIs at runtime — fetch, XMLHttpRequest, WebSocket, clipboard events, innerHTML — and enforces policies before operations complete, entirely locally.

Key characteristics:

• No network proxy required — detection and enforcement run in the extension at under 5ms, locally

• AI platform coverage — prompt inspection for ChatGPT, Claude.ai, Gemini, Copilot, Perplexity, Meta AI, and others

• Data exfiltration prevention — blocks PII, API keys, JWTs, and sensitive content leaving via network requests to external domains

• Enterprise deployment — distributed via Chrome Browser Cloud Management, Microsoft Intune, Firefox Enterprise Policy, or MDM profiles (Jamf, Mosyle)
