About this extension
GuardRail Browser Security provides enterprise-grade protection against malicious websites, phishing attempts, and online threats using advanced AI technology.

KEY FEATURES:
✓ Real-time threat detection using local AI models
✓ Privacy-focused - minimal data transmission
✓ Instant blocking of detected threats
✓ Customizable whitelist for trusted sites
✓ Monitor mode for testing without blocking
✓ Lightweight and fast - minimal performance impact
✓ Enterprise deployment ready

HOW IT WORKS:
GuardRail uses a two-layer protection system. Initial AI detection happens locally in your browser, with cloud verification only for unknown threats. Like a highway guardrail that keeps you from going off the road, GuardRail keeps you from visiting dangerous sites.

PERFECT FOR:
• Businesses requiring secure browsing
• MSPs protecting multiple clients
• Privacy-conscious users
• IT departments managing endpoints
• Anyone wanting protection from phishing and malware

PRIVACY FIRST:
GuardRail minimizes data transmission. Only URLs are sent for verification when needed - never page content, passwords, or personal data. All initial threat detection happens locally.

MONITOR MODE:
Test GuardRail's protection without blocking. Monitor mode logs potential threats without interrupting your browsing, perfect for evaluation periods.
