Sentinel Pro

AI-powered protection that checks every link before you visit it.

Sentinel Pro protects you from phishing attacks, fake websites, and suspicious emails in real time — without relying on blocklists that take days to catch new threats. Most security extensions only block sites that have already been reported. Sentinel Pro analyzes what you're viewing right now, detecting attack patterns as they happen. What it protects against: • Spoofed brand websites — detects URLs impersonating PayPal, Amazon, Google, Microsoft, banks, and more (paypa1.com, amaz0n.net, g00gle.com, etc.) • High-risk domains — flags TLDs commonly used for fraud (.tk, .xyz, .click, .top, .loan, and more) • Suspicious link patterns — identifies phishing keywords embedded in URLs • Email threats — scans the email you're currently viewing in Gmail to flag suspicious content, fake urgency, and dangerous links before you click How it works: The extension scans webpages and emails in real time using local pattern analysis. When something suspicious is detected, a clear warning banner appears explaining exactly why it was flagged. All analysis happens locally in your browser — nothing is sent to external servers. 🚨 License Required (Important): Sentinel Pro requires a valid license key to activate.
