5 Inconvenient Truths: How Agentic AI Breaks Your Security Playbook

This briefing outlines five core risks posed by Agentic AI: authenticated agents act as digital insiders that can exploit existing permissions; traditional defenses are designed for human-scale attacks and fail at machine velocity; non-human identities (API keys, service accounts, agents) have proliferated, causing sprawl and overprivilege; static API keys are a persistent structural weakness with huge blast radii; and incremental controls won’t suffice. The author advocates for a fundamental authorization redesign based on short-lived, just-in-time credentials and centralized, policy-driven dynamic authorization to enforce least privilege in real time.
