๐Ÿ›ก๏ธ LinkSentry โ€” Your Invisible Bodyguard While Browsing

LinkSentry automatically protects you from phishing, IP trackers, fake downloads, browser lockers, and fake shops โ€” before you even notice.

WHY LINKSENTRY?

Every day, millions of people fall victim to online scams. Scammers are getting more sophisticated โ€” 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 โ€” before your data is ever sent.

FREE FEATURES

๐Ÿ”’ Phishing Protection
Automatically blocks 157,000+ known scam sites from 4 daily-updated feeds. Sites are blocked at network level โ€” they never even load.

๐Ÿ“ 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.

โŒจ๏ธ 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).

๐Ÿ’พ Download Protection
Pauses suspicious downloads (.exe, .msi, .dmg) from unknown or very new domains and warns you before you open them.

๐Ÿ”’ Browser Locker Protection
Prevents websites from freezing your browser with fake virus warnings designed to trick you into calling a scam hotline.

โš™๏ธ Protocol Blocker
Blocks 45 dangerous protocols (ms-settings, steam, discord, etc.) that try to launch programs on your computer.

๐Ÿ”— Tab Protection
Automatically prevents websites from manipulating your other open tabs (reverse tabnabbing).

๐Ÿ”” Notification Blocker
Blocks fake captcha tricks that cause browser notification spam on your desktop.

๐Ÿ“‹ Clipboard Protection
Blocks automatic clipboard access that wasn't initiated by you.

๐Ÿช Fake Shop Detection
Analyzes online shops for suspicious signals: new domain, missing legal pages, crypto-only payments, extreme discounts.

๐Ÿ”’ Form Protection
Warns you when you enter passwords or credit card data on suspicious sites.

๐ŸŒ WebRTC Protection
Prevents suspicious sites from reading your real IP address via WebRTC โ€” even if you're using a VPN.

Right-click any link, then "Check with LinkSentry" โ€” instantly see if it's safe without opening it.

๐Ÿ“Š Dashboard
Clean dashboard shows you how many threats have been blocked.
