RUNTIME CONTAINMENT FOR AGENTIC AI

Prompt security stops what your AI says. We stop what it does.

Your AI agents can now call APIs, move data, trigger payments and control systems on their own. GhostMesh Grid sits at that exact boundary — between an agent's decision and its execution — and enforces what is, and isn't, allowed to happen.

Your AI has hands now. Most defenses only watch its mouth.

Autonomous agents don't just generate text. They call functions, hit real APIs, write to real databases, and — increasingly — trigger real-world actions with no human in the loop. A model that's perfectly "aligned" in conversation can still be manipulated, mis-scoped, or simply wrong at the moment it decides to act.

That's the gap GhostMesh Grid was built for: not another layer of prompt filtering, but a control plane for what agents are actually allowed to execute — with the ability to cut them off mid-action, instantly, across every system they touch.

Four components. One job: nothing executes unverified.

Component
What it does
Why it matters
01 — Sentinel Nodes

Lightweight interceptors deployed at every tool-call, API, and action boundary an agent can reach.

Nothing an agent does reaches a real system without first passing through one.

02 — PolicyMesh

Versioned, cryptographically signed policy graphs defining exactly which actions each agent, role, or context may take.

Policy is data, not a prompt — it can't be argued with, reasoned around, or overridden by clever phrasing.

03 — Kill Fabric

A distributed, redundant revocation layer that freezes an agent's execution rights across every connected Sentinel Node at once.

One switch, one command, every node — an agent going wrong doesn't require chasing down every integration by hand.

04 — Attestation Ledger

An immutable, queryable record of every action an agent attempted — approved or denied.

When something goes wrong, you get a forensic trail instead of a shrug.

Every agent action passes through the same four gates

01

Intercept

The agent's intended action is captured at the Sentinel Node before it reaches the real API, database, or system.

02

Verify

The action is checked against PolicyMesh and the agent's current behavioral baseline in real time.

03

Attest

The decision — approved or denied — is written to the Attestation Ledger, permanently and immutably.

04

Contain

If the action violates policy or trips an anomaly rule, Kill Fabric can revoke that agent's execution rights instantly.
