In my previous Baby Steps episode, we reviewed smart ways to implement data loss protection for every client. This episode focuses more so on outward protection with Safe Links and Safe Attachments in Defender for Office 365. This is available as a part of the Microsoft 365 Business Premium suite, or standalone through Defender for Office 365 licensing.

Safe Links and Attachments add key features to communications security:

  • Link Scanning and Analytics: Proactive scanning of link content through link rewriting allows the service to intercept links later deemed to be unsafe.
  • Attachment Sandboxes: Suspicious attachments are sent to an advanced sandboxing service, where their actions are evaluated through detonation.
