An e-commerce company is experiencing a significant increase in malicious login attempts and potential data exfiltration from their Azure Blob Storage accounts. They need a security information and event management (SIEM) and security orchestration, automation, and response (SOAR) solution that can collect security data from across their Azure environment, detect advanced threats using AI, and automate responses to security incidents. Which Azure service should they implement?

Why the other options are wrong

• B. Azure Active Directory Identity Protection focuses specifically on detecting identity-based risks and automating remediation for user accounts, not broad threat detection across the entire Azure environment.
• C. Azure Firewall provides network-level threat protection and filtering for Azure Virtual Network resources, but it is a perimeter security service, not a SIEM/SOAR solution for broad threat detection and incident response.
• D. Azure Security Center (now Microsoft Defender for Cloud) provides cloud security posture management (CSPM) and cloud workload protection (CWPP), offering security recommendations and threat protection, but it is not a full SIEM/SOAR solution for cross-enterprise threat detection and automated response.
