Cyber Immunity in the AI Era: Why Traditional Security Fails Agentic AI

Traditional cybersecurity fails against AI-powered threats because humans with administrative privileges remain the weakest link. The Lapsus$ breaches and recent PAM vendor compromises (BeyondTrust, Okta) illustrate how centralizing authority creates catastrophic single points of failure. Tide Foundation proposes 'Emergent Authority' — an architecture where sensitive credentials never exist in a stored, stealable state. Instead, cryptographic authority materializes just-in-time only when all conditions are met. Their open-source implementation, KeyleSSH, applies this to Privileged Access Management: administrators authenticate via zero-knowledge login, no keys are ever stored or rotated, and high-consequence commands require multi-admin cryptographic approval. The goal is 'cyber immunity' — a system where even a successful breach yields nothing of value to attackers.
