Detect deceptive login pages as you browse

Grizzly for Chrome is a lightweight browser extension that warns you when a page impersonates a trusted brand.

Phishing pages often look legitimate

  • Attackers clone trusted brands with convincing visuals
  • URL checks and reputation systems often miss these pages
  • Users only realize the problem after credentials are stolen

EMAIL PROTECTION

Scan links in Gmail

Protection that lives in your toolbar

One click shows the extension's status, runs a classification on the current page, and lets you toggle Gmail link scanning — no dashboards, no setup.

Email protection

Grizzly for Chrome checks links in your Gmail inbox against the same classification engine that protects login pages — before you click them. A warning banner appears on suspicious messages so you know to be careful.

Only URLs are scanned. Grizzly for Chrome never reads email content, never stores messages, and operates without an account.
