Overview

Highflame Browser Security protects enterprise users from AI-related threats at the browser level. It deploys as a managed extension across Chrome, Firefox, Safari, and Edge, intercepting browser APIs and network traffic in real time to detect and block prompt injection attacks, data exfiltration, token theft, and other threats before they reach AI platforms or leave the network.

All threat detections and policy violations are reported to Highflame Studio, giving security teams unified visibility alongside their agent and gateway guardrails.


What it protects against

Browser Security focuses on threats that originate in or pass through the browser — attacks that occur when employees use AI platforms directly, and data leaks that happen before any server-side control can intervene.

Threat category
Examples

AI prompt injection

Jailbreak attempts, role hijacking, instruction overrides, system prompt leaks sent to ChatGPT, Claude, Gemini, Copilot, and other AI platforms

Data exfiltration

PII, credit card numbers, SSNs, API keys, and JWTs sent to external domains via fetch or XHR

Token theft

Bearer tokens and JWTs intercepted and sent to unauthorized external endpoints

Sensitive file uploads

Documents containing regulated or sensitive content uploaded to AI platforms

Clipboard attacks

Malicious content pasted into AI chat interfaces

XSS and script injection

Unsafe HTML injected into innerHTML; dangerous eval() calls


How it works

The extension installs a lightweight security kernel (12.7 KB) into every browser tab. The kernel intercepts browser APIs at runtime — fetch, XMLHttpRequest, WebSocket, localStorage, sessionStorage, innerHTML, and clipboard events — and evaluates each operation against your active policies before allowing it to proceed.

Targeted threat detections run locally — request content is sent to Highflame and recorded for audit & compliance. Policy evaluation runs synchronously, adding no perceptible latency to normal browsing.


AI platforms monitored

Browser Security applies prompt inspection to traffic destined for:

  • ChatGPTchatgpt.com, chat.openai.com

  • Claudeclaude.ai, api.anthropic.com

  • Google Geminigemini.google.com

  • Microsoft Copilotcopilot.microsoft.com, sydney.bing.com

  • Perplexityperplexity.ai

  • Meta AImeta.ai

and more...

Policy controls apply for AI data exfiltration, token theft, and storage threats.
