Bastion

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.
