Configure Connectors and Agents for Hybrid and Multi-Cloud Onboarding

Connecting hybrid and multi-cloud environments to Microsoft Defender for Cloud brings unified threat detection, vulnerability assessment, and security posture management into one view. By integrating resources from Azure, on-premises, AWS, and GCP, you gain consistent protection across every environment. This approach reduces complexity and ensures that all assets are covered by the same security policies. As threats evolve, having a single platform makes it easier to spot risks and respond quickly.

To begin, deploy Azure Arc-enabled servers to bring your on-premises and multi-cloud machines under Azure’s control. This step allows Azure services to treat those resources as if they were native Azure VMs. Once connected, you can apply Azure policies, monitor performance, and install agents just like you would for any Azure-hosted VM. The deployment process involves registering each server and installing the Arc agent, which links to your Azure subscription. This integration is the foundation for consistent security across diverse platforms.

Next, register your AWS and GCP subscriptions within Azure to make those resources visible in Defender for Cloud. Registration is a simple process that uses the Azure portal or CLI to link each subscription. Once linked, you can view AWS and GCP workloads alongside Azure VMs in a single dashboard. This unified view helps you compare risk levels and apply the same standards everywhere. It also paves the way for automated policy enforcement across all cloud providers.

After registration, assign least-privilege service principals to secure the connection without granting excessive permissions. Following the principle of least privilege reduces attack surfaces and limits the impact if a credential is compromised. Service principals should have just enough rights to collect telemetry and enforce security policies. You can manage these roles through Azure role-based access control (RBAC), ensuring each connector follows secure integration practices. Proper role assignment is critical for maintaining compliance and guarding against unauthorized changes.

Finally, enable auto-provisioning of Defender for Cloud agents on your hybrid and cloud workloads and verify continuous telemetry ingestion. Auto-provisioning ensures that every new VM or server automatically installs the security agent, providing instant protection. Continuous telemetry ingestion gathers data on system events, network flows, and vulnerability scans. This data feeds into your secure score and policy enforcement engine, highlighting areas that need attention. By maintaining consistent monitoring and policy checks, you can respond faster to threats and keep your security posture strong.

Conclusion

In this section, you learned how to unify security across Azure, on-premises, AWS, and GCP by using Microsoft Defender for Cloud connectors and agents. You discovered the importance of deploying Azure Arc-enabled servers to bring external resources under Azure management and how registering AWS and GCP subscriptions makes all workloads visible in one place.

You also explored assigning least-privilege service principals to create secure integrations and minimize risk, as well as enabling auto-provisioning of agents to guarantee immediate protection for new resources. The final step of verifying continuous telemetry ingestion and secure score policy enforcement ensures that your security data is always up to date and that policies are consistently applied.

By following these steps, you achieve a streamlined security process that covers every environment with the same high standards. This holistic approach simplifies management, reduces gaps in protection, and helps you maintain a robust security posture throughout your hybrid and multi-cloud deployments.
