The architecture
Cybersecurity Mesh Architecture (CSMA) replaces the broken perimeter with a composable ecosystem: every security tool you already own becomes a cooperating node, sharing intelligence and enforcing one central policy.
Origin
CSMA was originated by Patrick Hevesi during his tenure as a Gartner analyst — and named a top strategic technology trend. Today, Patrick is CTO & Chief Architect of Cyber Mesh Security, building the first pure-play, AI-native platform to execute the blueprint he drew.

Foundations
LAYER 01
Collects telemetry and threat intel from every tool, correlates it centrally, and turns it into response triggers.
Predictive models score every asset against live adversary behavior, surfacing attacks while still hypothetical.
LAYER 02
Decentralized identity and adaptive access — identity becomes the real perimeter, enforced everywhere.
Identity is a first-class node in the path graph; risky entitlements are flagged as future hops.
LAYER 03
One central policy, translated automatically into the native config of each tool — no drift between intent and reality.
Agentic AI writes and pushes the per-tool enforcement that severs a path, then verifies it.
LAYER 04
A composite view across the ecosystem, so teams respond as one organism instead of forty consoles.
A single control plane shows every path, prediction, and automated action — with full audit trail.
Principles
WHY NOW — the perimeter is gone, adversaries wield Dark AI, and 40–60 disconnected tools can't see the path between them.
