The Phish Alert Button (PAB) Chrome Extension for Google Apps or Google Workspace gives your end-users the ability to report suspicious emails and empowers your employees to take an active role in managing the problem of phishing and other types of malicious emails. The tool can also provide your IT or risk management team with early warning of possible phishing attacks or malicious emails so they may take timely and effective actions to prevent security breaches or network compromise.
Paid Integration: If you have a paid account, the PAB will also track whether your users report our simulated phishing emails, so you can see which users successfully identify potentially malicious emails.
We encourage you to inform all of your users of this tool before making it accessible. To help inform your users, here are helpful resources that you can use to assist with the implementation of the PAB:
