S10: The Defender's Agentic Stack

Microsoft, Splunk, and Google SecOps shipped agentic SOCs in 2026. Red-team agents recon 24/7. Blue-team agents triage in seconds. The tempo shifted. Human judgment retreated to fewer but higher-stakes calls. Your detection stack, runbooks, and red-team rules of engagement all have to catch up.

Platform owns the substrate, not the agent. Telemetry pipeline, policy-as-code runbooks, detection-as-code libraries, and the confidence-band policy that decides what the agent runs unsupervised. This is a platform-engineering charter, not a vendor buy.
