Overview

Bailey barks before you type your Microsoft 365 password into a fake sign in page. A no cost tool from Cyber Grants Alliance.

Meet Marshall Bailey, a golden doodle on duty who watches your sign-in pages. Scammers build fake Microsoft 365 sign-in pages that look exactly like the real thing. One typed password is all they need to read your email, send invoices in your name, and get into your files. Marshall Bailey looks at every page that shows a Microsoft-style sign-in form. If the page is not really Microsoft, Bailey blocks it before you can type anything and tells you, in plain words, why. What Bailey does: - Blocks fake Microsoft 365 sign in pages and explains what to do next. - Shows a small green badge on the real Microsoft sign-in page, so you know it is safe. - Keeps up with new scams by downloading the latest public detection rules. What Bailey does not do: - Bailey does not collect your browsing history, your passwords, or anything you type. - Bailey has no ads, no tracking, and no analytics. - Detection runs inside your browser. The only download is the public detection rules file. Marshall Bailey by Cyber Grants Alliance is a no-cost tool from Cyber Grants Alliance, a nonprofit that helps small businesses and community organizations protect themselves from cyber attacks.
