Real-time web security and phishing protection extension powered by DOM heuristics and threat intelligence. 🛡️ ShieldGuard - Next-Generation Real-Time Web Security & Phishing Defense Protect your digital identity, passwords, and sensitive financial credentials from deceptive phishing sites, fake login portals, and unencrypted form threats with ShieldGuard. ShieldGuard works silently in the background as you browse the web, analyzing domain reputation and executing client-side DOM heuristics in real-time. Whenever an insecure password form, suspicious domain, or phishing signature is detected, ShieldGuard instantly alerts you before your credentials can be compromised. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌟 KEY FEATURES & HIGHLIGHTS ⚡ Real-Time Main-Frame Inspection Powered by Manifest V3 service workers, ShieldGuard evaluates every website navigation in real time without slowing down page rendering or network performance. 🔒 Insecure Password Form Detection (HTTP Heuristics) Entering credentials on an unencrypted page puts you at risk. ShieldGuard automatically flags any password field (<input type="password">) hosted over unencrypted HTTP protocol and alerts you instantly. ⚠️ Cross-Domain & IP Form Action Defense Deceptive phishing sites often host fake login forms that post data to external servers or raw IP addresses. ShieldGuard inspects form action targets and warns you before submission. 🛡️ Style-Isolated Shadow DOM Alert Banners When a threat is identified, ShieldGuard injects a high-priority warning banner directly onto the page. Using Shadow DOM style isolation, host page CSS can never hide or obscure security alerts. ⚡ Intelligent Domain Caching Built with a high-performance in-memory LRU cache to eliminate duplicate network lookups, ensuring zero impact on your browsing speed. 📊 Sleek Dark Glassmorphic Dashboard Click the ShieldGuard extension toolbar icon to view instant security breakdowns, active domain safety status, detected indicators, and toggle real-time protection anytime. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY & DATA SAFETY PROMISE • Zero Personal Tracking: ShieldGuard does NOT track your browsing history, sell user data, or store personal identifiers. • Local First Analysis: All DOM heuristics and password field inspections are performed locally in your browser. • Single-Purpose Security: Extension permissions are strictly restricted to network threat detection and browser protection. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 GET STARTED IN SECONDS 1.
