CybrGate

See every extension and AI agent in your browser, what it can reach, and why it's risky — scored on your machine, nothing sent out.

You installed the extensions. Do you know what they can actually do? A single browser extension with the right permissions can read every site you're logged into, capture what's on your screen, or quietly send your data to a server you've never heard of. Most permission checkers list those permissions one at a time and add up a number, which is why their warnings get ignored. "Reads cookies" on an ad blocker is nothing. "Reads cookies" plus "access to every site" is your logged-in sessions walking out the door. CybrGate scores the combination, and explains every point in a sentence you can argue with. It reads the real inventory of what's installed, scores each extension by what its permissions can do together, and flags the things that actually matter: an extension that can disable your other security tools, one that updates itself from a server outside the Web Store, one that quietly added access to every site in its last update. It also watches for AI agents. Browser AI agents and automation can be hijacked by malicious text hidden on a web page ("prompt injection"). CybrGate detects when something is acting as you, scans pages for text aimed at an agent, and can gate a high-risk action behind a confirmation the page itself cannot click. The free scan runs entirely on your machine. It needs no account, no sign-up, and it sends nothing anywhere. For teams: security leads can upgrade to see every employee's browser in one dashboard, push a single policy to the whole fleet, keep an audit log, and get deeper package-level analysis. Team is $8 per seat a month and Business is $12. The extension itself is free. A product of AR Dynamics Inc.
