Azure Security Tools: Secure Your Workloads and Data

Key Takeaways

1) Azure Security Tools help protect identities, networks, workloads, applications and data across Cloud environments.

2) Different tools address different security requirements, so organisations may need several complementary services.

3) Microsoft Defender for Cloud and Microsoft Sentinel support different areas of Cloud security, monitoring and threat detection.

4) Choosing appropriate tools should begin with security risks, architecture and operational requirements.

5) Effective Cloud security also depends on correct configuration, continuous monitoring and regular improvement.

Imagine your organisation runs several critical workloads in Azure. One morning, an unusual sign-in is detected. At the same time, suspicious network traffic appears and a security team discovers that one application is using sensitive credentials.

Which security tool should handle each problem?

The answer is unlikely to be just one.

Cloud environments have multiple security layers, from identities and networks to workloads, data and threat detection. This is why Microsoft Azure provides security services designed to address different risks and work together as part of a broader security architecture.

What is Microsoft Azure?

Microsoft Azure is a widely-used Cloud Computing platform that provides services for areas such as computing, storage, networking, databases, analytics, Artificial Intelligence (AI) and application development.

Organisations can use Azure to build, deploy and manage applications and infrastructure across Cloud and hybrid environments. Because these environments can contain sensitive data, applications and identities, security needs to be considered across multiple layers.
