Sentinel Pro

AI-powered cybersecurity — scans every link, detects phishing, breach monitoring, floating AI assistant, and more.

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: Heuristic scanning runs entirely on your device with zero network calls. When AI-powered scanning is enabled and you configure an API key, URLs are analyzed by your chosen AI provider (Anthropic or OpenRouter). To use fully local mode with no external traffic, simply leave the API key field empty in Settings. 🚨 License Required: Sentinel Pro requires a valid license key to activate. The extension will not function until a license is entered. Purchase through the official product page to receive your activation key and the Sentinel Pro Desktop app. Desktop App Features: Full threat logging File quarantine Threat history System-wide protection beyond the browser Privacy: Sentinel Pro does not collect your browsing data and does not require an account. All heuristic scanning happens locally. AI scanning (optional) sends URLs only to your configured provider — never to us.
