Cybercrime now rivals the GDP of major nations, and the pressure on defenders is relentless. We sit down with Microsoft’s CVP Security Vasu Jakkal to explore how AI is becoming the operating system of defense—turning 84 trillion daily signals into clear decisions, faster action, and a truly proactive posture. If you’ve felt stuck in alert fatigue or trapped by tool sprawl, this conversation offers a practical blueprint to simplify your stack, sharpen your visibility, and reclaim time.
We break down the core pillars of a modern security strategy: unifying telemetry with Microsoft Sentinel, using data lake tiers to keep rich history without blowing up costs, and mapping attacker movement with graph-driven insights. Vasu explains why attackers think in graphs, how defenders can do the same, and where consolidation across Defender, Purview, Entra, and Intune cuts complexity across 50+ categories. You’ll hear real results from healthcare and critical industries, with savings up to 50% and better detection through a single, connected view.
The episode also dives into Security Copilot and the new no-code Agent Builder—so any team can create specialized security agents that triage phishing, enrich alerts, and accelerate investigations without writing scripts. We talk about the Microsoft Security Store for discovering partner-built agents, the skills defenders need to thrive with AI, and how to prepare for the expanding attack surface, from prompt injection and jailbreaks to deepfakes and model poisoning. The takeaway is clear: when AI, graph analytics, and unified tooling meet, defenders can move from firefighting to foresight.
If you care about reducing noise, preventing lateral movement, and upskilling your team with AI, this one’s for you. Listen, share with your security peers, and tell us what agent you’d build first.
