This means that with Azure Arc, you can manage your on-premises servers and other cloud environments as if they were all part of a single, unified Azure ecosystem. When paired with Defender for Servers, Azure Arc brings together the power of cloud-native security with on-premises infrastructure, allowing businesses to streamline and centralize their security operations across all environments.

The Need for a Unified Security Solution

In today’s complex IT landscape, organizations face a myriad of security threats and vulnerabilities. Managing security for diverse environments—spanning public clouds, private clouds, and on-premises servers—requires a unified approach. Without such a solution, businesses risk security gaps, data breaches, and operational disruptions.

Microsoft Defender for Servers, integrated with Azure Arc, addresses these challenges head-on.
