This reduces response times and mitigates potential damage while allowing security teams to focus on high-priority threats.

Sentinel also provides advanced threat hunting capabilities. Security analysts can proactively query data to identify emerging threats, investigate anomalies, and validate indicators of compromise. Dashboards and reporting features offer visibility into security trends, incident status, and compliance metrics, which helps organizations understand their security posture and improve decision-making. Sentinel’s integration with Microsoft Defender for Endpoint, Microsoft Entra Identity Protection, and other security tools creates a coordinated ecosystem for threat detection and response.

Option B, Microsoft Entra Conditional Access, enforces access policies but does not investigate or respond to threats. Option C, Microsoft Purview Data Loss Prevention, prevents accidental data exposure but does not provide threat detection. Option D, Microsoft Secure Score, assesses security posture but does not monitor or respond to real-time security incidents.

Implementing Microsoft Sentinel allows organizations to monitor unusual sign-in attempts and respond effectively to potential security threats across their cloud and on-premises environments. Sentinel provides centralized visibility, automated response capabilities, and advanced analytics, helping organizations reduce risk, comply with regulatory requirements, and maintain a proactive security posture aligned with SC-900 objectives.
