Microsoft has enhanced Defender with new Security Exposure Management features, specifically targeting protection for critical infrastructure assets like domain controllers and web servers. This update moves beyond treating all endpoints equally, integrating asset importance to prioritise defence where it matters most. Key improvements include earlier detection of attacks on high-value systems, quicker automatic containment, and richer context for incident response. Microsoft highlights these defences with real-world case studies of credential theft and lateral movement, addressing growing attacker sophistication. While no solution guarantees full protection, Defender’s asset-aware approach provides more focused resilience, especially useful for hybrid and cloud-driven environments. As ever, combine these tools with robust patching, segmentation, and tested response plans for best results.
