Bastion

Bastion — Browser Security Shield: anti-fingerprint, anti-phishing, quantum-ready TLS, token scanner, tracker blocker

Protect your browser from phishing, trackers, fingerprinting, data exfiltration, and token theft. Detailed description: Bastion is a comprehensive browser security extension that works silently in the background to keep you safe. 🛡️ WHAT BASTION DOES: • Anti-Phishing — detects domains impersonating Google, Apple, Telegram, banks and 14+ major brands. Shows a full-screen warning before you enter any data. • Token Scanner — finds exposed JWT tokens, API keys, passwords and card numbers stored in your browser's localStorage, sessionStorage and cookies. • Tracker Blocker — blocks 300+ known tracking domains from Google, Facebook, TikTok, Amazon and others. • Security Headers Audit — grades every website (A–F) based on its HTTP security headers (CSP, HSTS, X-Frame-Options and more). • Anti-Fingerprinting — masks navigator properties to prevent sites from identifying your browser. • Anti-Exfiltration — monitors outgoing requests and alerts you when tokens are sent to third-party domains. • Anti-Miner — detects and blocks crypto mining scripts running in background workers. • Cookie Banner Hider — automatically hides GDPR/cookie consent banners on 500+ sites. • Tab-Napping Protection — prevents malicious pages from hijacking browser tabs. • Keylogger Detection — alerts when a page registers an unusual number of keyboard listeners. 🔒 PRIVACY FIRST: Bastion processes everything locally. No data is ever sent to our servers. No telemetry. No ads. 💙 Free and open. If Bastion saved your data, consider supporting development via the Support tab.
