About GuardDog - Extension Security Monitor

Are your Chrome extensions safe? In 2025-2026, over 30 malicious Chrome extensions were discovered, leading to $8.5M+ in cryptocurrency theft. GuardDog acts as an antivirus for your extensions — scanning permissions and scoring risks so you can spot threats. 🔍 INSTANT SECURITY SCAN Click "Scan" and GuardDog analyzes every installed extension's permissions, then calculates a risk score (0-100) with 4 levels: Low, Medium, High, and Critical. Your riskiest extensions are shown first. 💬 PLAIN-LANGUAGE EXPLANATIONS No more cryptic permission names. GuardDog explains what each permission actually means in plain English: • tabs → "Can see the URL and title of every open tab" • cookies → "Can read and modify website cookies, including login sessions" • <all_urls> → "Can read and modify data on ALL websites you visit" • 40+ permissions mapped — every single one explained clearly. 📊 RISK DASHBOARD Your popup shows a summary of all extensions at a glance: • Total extension count with breakdown by risk level • Top risky extensions with their biggest threat explained • Color-coded badges: 🟢 Low, 🟡 Medium, 🟠 High, 🔴 Critical • High-risk badge indicator on the extension icon 🔒 PRIVACY FIRST GuardDog works entirely on your device — no servers, no data collection, no tracking. ✅ No network requests — works 100% offline ✅ No data collection — everything stays on your device ✅ No content scripts — never touches your web pages ✅ No host permissions — cannot access your browsing data ✅ Only 4 permissions: management, notifications, storage, alarms 🌍 PERFECT FOR • Anyone worried about extension security after recent crypto theft incidents • Developers who install many extensions and want a quick risk check • Security-conscious users who want to understand what their extensions can access • IT teams evaluating browser extension safety Built to protect the millions of Chrome users who don't know what their extensions can really do.
