About this extension
PhishGuard is a high-performance, real-time security extension designed to catch the malicious websites that traditional antivirus software misses.

Hackers get smarter every day, constantly creating new, stealthy "zero-day" phishing sites designed to steal your passwords and identity. PhishGuard fights back using an advanced, cloud-hosted Machine Learning model. Every time you visit a new webpage, PhishGuard instantly analyzes the URL against 18 distinct threat heuristics—such as suspicious keywords, punycode deception, missing HTTPS, and domain entropy.

If a site attempts to mimic a trusted login portal or exhibits dangerous characteristics, PhishGuard immediately injects a high-visibility warning screen into your browser, giving you the chance to back away safely.

Features:
• 🧠 Cloud-Powered Machine Learning: Analyzes URLs in milliseconds without slowing down your computer.
• 🛡️ Zero-Day Protection: Detects brand-new phishing sites by their structural DNA, not just by comparing them to known blacklists.
• ⚡ Blazing Fast: Edge-deployed threat detection ensures warnings appear before malicious scripts can execute.
• 🤝 Crowdsourced Intelligence: Found a threat? Report it instantly through the extension to improve the model for everyone.
• 🟢 Trusted Whitelisting: Easily curate your own list of 100% safe domains.

Take control of your browsing safety. Install PhishGuard today.
