Microsoft just upgraded Sentinel with an AI-powered data lake - here's how it works

The new "agentic defense" system is intended to help organizations manage the mountains of data that are being collected in the burgeoning AI era.

The company is also tapping into the cultural caché surrounding agents, or AI systems that can interact with external digital tools and autonomously perform tasks without explicit prompting from human users. The goal is to provide cybersecurity professionals with a more expansive and fine-grained level of visibility into the full spectrum of their security data, while at the same time automatically taking action to optimize protection from external threats. The proliferation of powerful AI tools in recent years has produced a cybersecurity arms race: while these systems present new possibilities for fraudsters and scam artists -- who use them to brute-force passwords and mimic the voices of real people, just to name a couple of examples -- they're also being used to strengthen protections against cyberattacks.
