Microsoft Defender for Identity vs Azure ATP
Azure ATP was the former version of Microsoft Defender for Identity. It was renamed in 2020 as part of Microsoft’s efforts to streamline its product names and improve customer experience. While the names have changed, the primary purpose and functionalities remain the same. Let’s underline this with a simple table:
| Functions | Azure ATP | Microsoft Defender for Identity |
|---|---|---|
| Threat detection | Yes | Yes |
| Threat response | Yes | Yes |
| Actionable insights | Yes | Yes |
Simply, they are different names of the same product, offering a high level of security for your IT environment by detecting and investigating security incidents.
Understanding the capabilities of Microsoft Defender for Identity is vital for security professionals, especially those preparing for the SC-900 Microsoft Security, Compliance, and Identity Fundamentals exam. Its unique mechanism for detecting and responding to threats, alongside actionable insights, make it a critical tool in modern-day cybersecurity strategy.
For instance, consider a situation where an unusual trend of data access from a privileged account is noticed. In such a scenario, Defender for Identity can alert the security personnel about the anomaly, enabling them to take necessary precautions and perhaps initiating measures to reset the account credentials or even close the account temporarily if deemed necessary.
Microsoft Defender for Identity, therefore, plays a pivotal role in securing the enterprise system, and comprehending its functionalities is crucial to understand and address a key area in the SC-900 exam blueprint.
