About this extension

Detects suspicious login pages and phishing attempts.

Read the publisher’s full description

Grizzly helps protect you from phishing attacks at the exact moment they become dangerous: when you are about to sign in. Modern phishing pages are often indistinguishable from real websites. They may be newly created, hosted on well-known platforms, or designed to bypass traditional blocklists and browser warnings. Grizzly is built to detect these deceptive login pages before you enter sensitive information. Grizzly runs automatically in your browser and activates only on pages that request credentials. It looks at the overall context of a login page and evaluates whether it behaves in a way that is consistent with what it claims to be. If a page appears suspicious, Grizzly warns you before credentials are submitted, giving you a chance to stop and reassess. Key principles • Designed for modern phishing attacks: Grizzly focuses on deceptive login behavior rather than relying only on known bad websites. • Automatic and unobtrusive: Once installed, Grizzly works quietly in the background and requires no configuration. • Clear, timely warnings: You are only alerted when a login flow appears risky or misleading. Privacy-first by design Grizzly does not collect or store sensitive information. • Passwords and form inputs are never captured • Browsing history is not tracked • Only minimal information related to login detection is analyzed Grizzly activates only on authentication pages and does not monitor general browsing. What Grizzly does not do • It does not block websites automatically • It does not scan emails or messages • It does not analyze downloads or malware • It does not monitor accounts after login
