Difference Between Azure Security Center and Azure Sentinel
Azure Security Center (ASC)
Azure Security Center is primarily focused on:
- Security Posture Management: ASC helps organizations assess and improve their security posture across Azure resources and hybrid environments.
- Threat Protection: It provides advanced threat detection capabilities using machine learning and analytics to identify and respond to potential security threats.
- Security Policies and Compliance: ASC helps enforce security policies and regulatory compliance, offering recommendations based on industry standards like CIS benchmarks.
Azure Sentinel
Azure Sentinel, on the other hand, is designed for:
- Security Information and Event Management (SIEM): It acts as a cloud-native SIEM and Security Orchestration, Automation, and Response (SOAR) solution.
- Threat Intelligence and Analytics: Azure Sentinel aggregates data from various sources, including Azure Security Center, and uses AI and machine learning to detect and respond to threats.
- Incident Response and Investigation: Sentinel provides tools for incident response, investigation, and hunting, allowing security teams to analyze and remediate security incidents efficiently.
Key Differences
- Focus and Functionality:
- ASC: Focuses on managing and improving the security posture of Azure resources through continuous monitoring and compliance management.
- Sentinel: Focuses on collecting, analyzing, and responding to security data from multiple sources to detect and mitigate threats across the entire IT environment.
- Use Cases:
- ASC: Ideal for organizations looking to strengthen their cloud security posture, manage compliance, and gain insights into security vulnerabilities specific to Azure services.
- Sentinel: Suited for organizations needing a centralized platform for security monitoring, threat detection, and response across cloud and on-premises environments.
- Integration:
- ASC: Integrates with other Azure services like Microsoft Defender ATP and Azure Policy for enhanced security management and compliance.
- Sentinel: Integrates with a wide range of Microsoft and third-party security solutions, offering flexibility in data ingestion and analysis for comprehensive threat management.
Choosing the Right Solution
- For Cloud Security Management: Choose Azure Security Center if your primary focus is on managing Azure-specific security policies, compliance, and assessing the security posture of Azure resources.
- For Threat Detection and Response: Opt for Azure Sentinel if you need advanced capabilities for security monitoring, threat detection, incident response, and integration with diverse data sources.
