Inline Protection

Important:

This is a "Pre-release" feature and is not considered an official release. Please review the Pre-release Disclaimer before using the feature.

In addition to the existing protection mechanism, Cloud App Security launches inline protection that detects and remediates threats before they can reach your protected services. In this mode, traffic needs to pass through Cloud App Security on the way to its destination, allowing Cloud App Security to scan for and take action on threats in real time.

Cloud App Security supports inline protection for Exchange Online in both inbound and outbound directions.

  • Inbound protection: Scan messages sent from outside your organization before they reach the protected mailboxes in your organization.

  • Outbound protection: Scan messages sent from protected mailboxes in your organization before they are delivered to their destinations outside your organization.

The following describes how to use inline protection for Exchange Online.

Note:
