Real-time phishing and fraud detection. Protects you from malicious links and suspicious emails. PhishGuard protects you from phishing attacks, fraudulent websites, and malicious links — in real time, as you browse. Every link on a page is automatically scanned before you click it. Dangerous links are flagged with a clear visual warning. Safe links are left untouched. No popups, no interruptions — just silent protection running in the background. ━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━ PhishGuard uses a multi-layer detection system: → Domain Whitelist — instantly clears millions of known-safe domains (Google, GitHub, Wikipedia and more) with zero API calls → Rule-Based Heuristics — flags suspicious TLDs, excessive subdomains, phishing keywords, unencrypted HTTP connections, and IP-based URLs → AI / ML Detection — a BERT-based machine learning model trained specifically on phishing URLs analyses anything that passes the first two layers → Enhanced Mode (optional) — adds IPQualityScore reputation analysis for confirmed threat scoring on top of the ML result The result: fast, accurate, multi-signal phishing detection that catches both known threats and novel zero-day phishing attempts. ━━━━━━━━━━━━━━━━━━━━━━ STANDARD vs ENHANCED ━━━━━━━━━━━━━━━━━━━━━━ Standard mode is free with no account required. It uses the whitelist, rules engine, and AI model to protect you out of the box. Enhanced mode adds a second layer of real-time URL reputation scoring powered by IPQualityScore.
