Tell us who to contact for important matters

Defender Experts for XDR lets you determine the individuals or groups within your organization that need to be notified if there are critical incidents, service updates, occasional queries, and other recommendations:

  • Incident notification contacts – These contacts are persons or teams that we can notify for managed response actions or any communication that requires immediate response. Given the urgent nature of the communications, we recommended that these contacts are always available.
  • Service review contacts – These contacts are persons or teams that we can engage with for ongoing security briefings done by our service delivery team.

Once identified, the individuals or groups will receive an email notifying them that they were as a contact for incident notification or service review purposes.

Prepare your environment for the Defender Experts service

Apart from onboarding service delivery, our expertise on the Microsoft Defender XDR product suite enables Defender Experts for XDR to let you run a readiness assessment and help you get the most out of your Microsoft security products.

The readiness assessment is based on the number of protected devices and identities in your environment, and Defender Experts' policy recommendations. To view the assessment, in your Microsoft Defender portal, go to Settings > Defender Experts then select Service status.

Screenshot of readiness assessment environment.

The readiness assessment has two parts:

  • Actions needed – This section shows the number of actions or security settings that you need to complete, are in progress, or have been completed. These actions are listed in a table at the bottom part of the page.

    The list outlines the required steps you need to take before initiating the service. Prioritize the actions that have the Complete now status to get the Defender Experts for XDR service started sooner.

    Note

    It can take up to 24 hours to get the latest status of your security settings.

  • Protected assets – This section shows the current number of protected devices and identities versus the ones that you still need to protect to get the Defender Experts for XDR service started.

    The figures are based on your Defender for Endpoint and Defender for Identity licenses; to achieve these target number of protected assets, onboard more devices to Defender for Endpoint or install more Defender for Identity sensors.

Important

Defender Experts for XDR reviews your readiness assessment periodically, especially if there are any changes to your environment, such as the addition of new devices and identities. It's important that you regularly monitor and run the readiness assessment beyond the initial onboarding to ensure that your environment has strong security posture to reduce risk.

After you complete all the required tasks and met the onboarding targets in your readiness assessment, your service delivery manager (SDM) initiates the monitoring phase of the Defender Experts for XDR service, where, for a few days, our experts start monitoring your environment closely to identify latent threats, sources of risk, and normal activity. As we get better understanding of your critical assets, we can streamline the service and fine-tune our responses.

Once our experts begin to perform comprehensive response work on your behalf, you’ll start receiving notifications about incidents that require remediation steps and targeted recommendations on critical incidents. You can also chat with our experts or your SDMs regarding important queries and regular business and security posture reviews, and view real-time reports on the number of incidents we’ve investigated and resolved on your behalf.
