Azure-named services provide an indication of Azure functionality and capabilities, even if these services provide hybrid cloud features and capabilities. This is why Microsoft has recently changed the name of many Azure services, including those in its security portfolio, to align the services with today's hybrid infrastructure models.

It has become apparent to Microsoft that Azure-branded services that offer hybrid cloud functionality may be misleading to customers. For example, some customers have mistakenly believed that the "Azure Security" solutions were only for Azure services due to product branding and marketing.

Microsoft is carrying out a major overhaul of the naming of security services to more accurately reflect the hybrid functionality these services contain. Note the following Azure security service name changes:

Old NameNew Name
Azure Security CenterMicrosoft Defender for Cloud
Azure Defender
Azure Defender for IoTMicrosoft Defender for IoT
Azure SentinelMicrosoft Sentinel
Azure Advanced Threat ProtectionMicrosoft Defender for Identity
Microsoft Cloud App SecurityMicrosoft Defender for Cloud Apps

The "Defender" branding is now used more consistently with the naming across the security portfolio. Let's see how each of these services fits into the overall Microsoft security portfolio. It helps to reflect the integrated security capabilities Microsoft offers across identities, endpoints, applications, email, IoT, infrastructure, and cloud platforms.

Microsoft Defender for Cloud ^

Microsoft Defender for Cloud is used for security posture management and threat protection. It helps ensure that businesses are ready for cyberattacks coming their way and includes a mix of best practices and technology tools. In addition, Defender for Cloud can protect workloads running in Azure, on-premises (hybrid configurations), and other cloud platforms. Using Defender for Cloud, organizations can harden cloud resources and see how their cloud security posture changes over time.

Microsoft Defender for IoT ^

With many organizations deploying latency-sensitive IoT workloads that need to exist close to the edge environment, IoT use in many environments has exploded. Microsoft Defender for IoT provides an agentless network detection and response (NDR) solution. It works with many IoT environments and devices, including industrial control systems. It also seamlessly works with Microsoft 365 Defender and Microsoft Sentinel. In addition, as the new Microsoft Defender branding indicates, it can be deployed in hybrid cloud environments with on-premises IoT and in the cloud.

Microsoft Sentinel ^

You can think of Microsoft Sentinel as modern, cloud-native security information and event management (SIEM) technology that leverages Microsoft's large-scale artificial intelligence-enabled security experience. Using years of information gathering and security intelligence "training," Microsoft Sentinel allows businesses to take advantage of AI-driven security monitoring. SIEMs are notoriously complex solutions to provision, "train," and operate. Using Microsoft Sentinel, businesses can operate a SaaS-based SIEM for their organization, with the benefit of allowing Microsoft to manage the underlying infrastructure.

Microsoft Defender for Cloud Apps ^

The Microsoft Defender for Cloud Apps helps organizations discover "shadow IT" operations and protect against data leakage of sensitive information. Defender for Cloud Apps has many other capabilities, including cyber threat protection, compliance assessment, governance, and security posture management. It allows protecting thousands of cloud-based applications in the Microsoft Defender catalog.

Wrapping up ^

The renaming of Microsoft security products helps align their security portfolio with the increasingly hybrid configuration of today's organizations. It also helps eliminate confusion around the context in which security solutions operate. For example, rather than Azure-only solutions, the Microsoft Defender portfolio covers infrastructure in Azure, on-premises (hybrid configurations), and even other public cloud environments.
