Microsoft Safe Links

Connect the Microsoft Safe Links data feed.

In this guide, you'll configure the integration between Radiant and Microsoft Safe Links. Safe Links scans and rewrites URLs in inbound emails and performs time-of-click verification to protect users from malicious links. To learn more, see Safe Links in Microsoft Defender for Office 365.

Integrating the Microsoft Safe Links data feed into Radiant gives your organization visibility into phishing emails accessed from unmanaged devices. With this data, Radiant can identify users who clicked on malicious links from personal devices, arming you with the data necessary to perform deeper investigations and reveal the full scope of an incident.

Additionally, we guide analysts to block access to URLs leveraging Safe Links when Microsoft has not already blocked them.
