Marius Sandbu Windows Ransomware Detection And Protection -

Detection must occur at the behavioral and identity layers—not just the file layer.

A central theme in Sandbu’s writing and speaking engagements is the acknowledgement that the "castle-and-moat" security model is obsolete. In a modern Windows environment, particularly one hybridized with Azure, the network perimeter is porous. Sandbu argues that attackers no longer need to "hack" in; they often "log in" using compromised credentials. Therefore, a foundational aspect of his protection strategy is the realization that the endpoint is the new perimeter. Sandbu emphasizes that organizations cannot rely on third-party legacy antivirus solutions that merely scan for known file hashes. Instead, he champions the use of Next-Generation Antivirus (NGAV) capabilities found within Microsoft Defender for Endpoint, which utilizes behavioral analysis and machine learning to detect anomalies before encryption begins. marius sandbu windows ransomware detection and protection
