Microsoft's 2026 Digital Defense Report Warns of Interconnected Security Threats

The Microsoft Digital Defense Report for 2026 highlights the growing interconnectedness of the security environment. Threat activity can span infrastructure, identities, applications, cloud environments, and software supply chains.

Artificial intelligence (AI) systems are increasingly interacting with data, tools, and business systems, making connections across an environment crucial to understanding both cyberthreats and defense.

The report notes that AI models are becoming more capable, automation is expanding, and new connections are forming across the systems organizations rely on. This development can change the speed and scale of security activity even as the underlying security fundamentals remain familiar.
