PhishHook Button - Centralised Deployment

In this article we will learn how to automatically install/roll-out the Microsoft Office 365 Outlook Phish Hook add-in button to all users at once.

The Phish Hook Button add-in for Microsoft Outlook / Office 365 gives end-users the ability to report suspicious emails. The button allows your employees to take an active role in managing the problem of Phishing and other types of malicious emails. This has the benefit of providing your IT/security team with early warnings of possible phishing attacks or malicious emails, allowing them to take effective action to prevent security or network compromise.

The button will also track if your users report our simulated phishing emails, so you can see which users are successfully engaging and identifying potentially malicious emails.
