Microsoft Defender for Cloud has the capability to perform external attack surface management (EASM), (outside-in) scans on multicloud environments. Defender for Cloud accomplishes this through its integration with Microsoft Defender EASM. The integration allows organizations to improve their security posture while reducing the potential risk of being attacked by exploring their external attack surface. The integration is included with the Defender Cloud Security Posture Management (CSPM) plan by default and doesn't require a license from Defender EASM or any special configurations.

With this information, security and IT teams are able to identify unknowns, prioritize risks, eliminate threats, and extend vulnerability and exposure control beyond the firewall. The attack surface is made up of all the points of access that an unauthorized person could use to enter their system. The larger your attack surface is, the harder it's to protect.
