Which feature in Microsoft Defender for Endpoint reduces the attack surface against cyberthreats?

Network protection is a crucial feature in Microsoft Defender for Endpoint designed to reduce the attack surface against cyberthreats. This feature helps to safeguard devices by controlling and blocking potentially harmful network traffic based on threat intelligence and security configurations. By effectively managing network traffic and blocking malicious connections, Network protection minimizes the risk of exploitation and helps secure endpoints from cyber attacks.

Moreover, this feature works proactively by restricting access to suspicious or untrusted networks, thereby preventing attackers from gaining entry into the system. It complements other security measures by ensuring that even if a vulnerability exists, the chances of an attacker leveraging it are significantly reduced through careful network management and monitoring.

In relation to the other features, while automated remediation, automated investigation, and advanced hunting are all important components of threat detection and response, they primarily focus on responding to incidents or identifying threats rather than actively preventing them from occurring in the first place. Network protection stands out as a preventative measure that directly addresses the attack surface, contributing significantly to an organization's overall security posture.
