LinkSentry

Security link extension — protects against phishing, tab-nabbing, and malicious URLs

🛡️ LinkSentry — Your Invisible Bodyguard While Browsing LinkSentry automatically protects you from phishing, IP trackers, fake downloads, browser lockers, and fake shops — before you even notice. ━━━━━━━━━━━━━━━━━━━━━━ WHY LINKSENTRY? Every day, millions of people fall victim to online scams. Scammers are getting more sophisticated — fake websites look identical to real ones, IP loggers hide in harmless-looking links, and fake downloads disguise themselves as popular software. LinkSentry detects these threats and blocks them at the network level — before your data is ever sent. ━━━━━━━━━━━━━━━━━━━━━━ FREE FEATURES 🔒 Phishing Protection Automatically blocks 157,000+ known scam sites from 4 daily-updated feeds. Sites are blocked at network level — they never even load. 📍 IP Logger Detection (UNIQUE!) Detects 70+ known IP tracking services like Grabify, IPLogger, and more. When someone sends you a tracking link, LinkSentry blocks it before your IP address, location, or device data is ever transmitted. ⌨️ Typosquatting Warnings Detects when you land on a fake domain that looks similar to a known website (e.g., paypa1.com instead of paypal.com). 💾 Download Protection Pauses suspicious downloads (.exe, .msi, .dmg) from unknown or very new domains and warns you before you open them. 🔒 Browser Locker Protection Prevents websites from freezing your browser with fake virus warnings designed to trick you into calling a scam hotline. ⚙️ Protocol Blocker Blocks 45 dangerous protocols (ms-settings, steam, discord, etc.) that try to launch programs on your computer. 🔗 Tab Protection Automatically prevents websites from manipulating your other open tabs (reverse tabnabbing). 🔔 Notification Blocker Blocks fake captcha tricks that cause browser notification spam on your desktop. 📋 Clipboard Protection Blocks automatic clipboard access that wasn't initiated by you. 🏪 Fake Shop Detection Analyzes online shops for suspicious signals: new domain, missing legal pages, crypto-only payments, extreme discounts. 🔒 Form Protection Warns you when you enter passwords or credit card data on suspicious sites. 🌐 WebRTC Protection Prevents suspicious sites from reading your real IP address via WebRTC — even if you're using a VPN. 🖱️ Right-Click Scanning Right-click any link, then "Check with LinkSentry" — instantly see if it's safe without opening it. 📊 Dashboard Clean dashboard shows you how many threats have been blocked. ━━━━━━━━━━━━━━━━━━━━━━ PRO FEATURES ⭐ Unlimited link scans ⭐ QR Code Scanner — check QR codes before scanning them with your phone ⭐ Email link protection — flags suspicious links in Gmail, Outlook, Yahoo ⭐ Messenger protection — flags links in WhatsApp Web and Telegram ⭐ OAuth consent scanner — warns about dangerous app permissions ⭐ Detailed reports — server country, redirect chain, certificate details ⭐ Evidence export — save evidence reports for law enforcement ⭐ Weekly protection report ⭐ Auto-cleanup — deletes cookies/trackers from suspicious sites ⭐ Fingerprint protection — prevents browser fingerprinting ━━━━━━━━━━━━━━━━━━━━━━ PRIVACY & TECHNOLOGY ✅ 100% local — no server, no database, no cloud ✅ Zero data collection — LinkSentry collects no personal data ✅ Open architecture — blocklists from Phishing Army, OpenPhish, URLhaus ✅ Manifest V3 — latest Chrome extension standard ✅ Network-level blocking — declarativeNetRequest blocks threats before a single byte is sent ✅ Auto-updates every 6 hours ━━━━━━━━━━━━━━━━━━━━━━ GET STARTED FOR FREE Full basic protection is and always will be free.
