We don’t just say it works—we show it, quarter over quarter. New email security benchmarking data is out now—built on real-world telemetry, not synthetic tests. The TL;DR: ➡️ Microsoft Defender consistently misses fewer high-severity cyberthreats than any SEG vendor evaluated ➡️ ICES vendors deliver the most value in promotional and bulk email filtering ➡️ Defender now drives the majority of post-delivery remediation See what other insights a year’s worth of data reveals.

AI Red Teaming is a discipline that continues to adapt and evolve as technology and usage of AI change. It has come a long way since 2019. Cynthia Brumfield has effectively framed this complex area and its rapid adaptation, incorporating interesting perspectives from Ram Shankar Siva Kumar 🦝, Tom Gillis, Ian Swanson, and Dane Sherrets. It was a pleasure speaking with Cynthia, and I look forward to witnessing the growth of AI Red Teaming in the coming years.

New Release: AI Investigator Playbook AI systems are now embedded in everyday work and security teams need a structured way to investigate what happens inside them. Today I'm sharing the AI Investigator Playbook, a practical guide for reconstructing AI activity across Microsoft 365 Copilot and Azure AI services using telemetry you already have. The playbook introduces a repeatable scope–context–signal sequence: identify who interacted with AI systems, understand what was accessed, and evaluate detection signals within that broader chain of activity. Inside you'll find: ✅ Schema references and KQL queries ✅ Detection logic for prompt injection, anomalous usage, and credential exposure ✅ Coverage for agent-based systems including deployment, configuration, and authorization ✅ A single working model that reduces ad hoc pivots during investigations The goal: move from isolated alerts to a coherent, reconstructed account of what occurred. 📥 Get the playbook → https://lnkd.in/g25sTDpW #CyberSecurity #AISecurity #IncidentResponse #ThreatDetection #Microsoft #SecurityOperations
