Every agent tool call, intercepted and inspected.
Cordon is a managed MCP security gateway that intercepts, inspects, and enforces policy on every AI agent tool call — giving your enterprise the visibility and control over agentic AI it doesn't currently have.

// the problem
Agentic AI is everywhere. Oversight is nowhere.
Teams are shipping AI agents across the business with no shared visibility and no shared controls — yet the organisation remains accountable for everything they do.
No visibility
Nobody can say who built each agent, what data it touched, what it produced, or what it cost. Agents multiply faster than anyone can inventory them.
Unsupervised & non-deterministic
Agents act on their own, and the same prompt can take a different path every run. Traditional change control was never designed for software that improvises.
No audit trail
When something goes wrong, there is no record of the tool calls that led there — yet the business is still accountable for the outcome.
The walled-garden trap
The incumbent answer is “build one sanctioned platform and force every team onto it.” That slows deployment, kills flexibility, and teams route around it anyway.
// the cordon answer
Let agents be built anywhere, on any stack — but route every tool call through Cordon's security layer. No rip-and-replace. No forcing teams onto a single platform. Visibility and policy enforcement without slowing deployment.
// how cordon works
Seven layers between your agents and the outside world.
Every MCP tool call passes through the full stack — from cryptographic identity at the edge to a complete audit record at the core.
L1
Attestation
Cryptographic identity verification for every MCP server. Unregistered or tampered servers never reach your agents.
L2
Semantic Analysis
Inspects the intent and content of every tool call — not just the endpoint it hits.
L3
Permission Sandbox
Enforces exactly what each agent is allowed to touch. Everything outside the sandbox is denied by default.
L4
Context Isolation
Prevents cross-contamination between agent sessions and data domains. One agent’s context never bleeds into another’s.
L5
Response Validation
Checks outputs before they are trusted — malformed, poisoned, or out-of-policy responses are stopped at the gate.
L6
Behavioural Monitoring
Baselines each agent over time and flags anomalous behaviour before it becomes an incident.
L7
Audit Trail
Full logging of who, what, when, and cost — an evidentiary record for security, finance, and compliance.
// trust registry
App Store review — for MCP servers.
The HLD Trust Registry gives MCP server developers a path to being trusted inside the enterprise: submit for review, receive a cryptographic attestation key, and Cordon verifies it on every single connection.
Register
MCP server developers submit their server to HLD for review — capabilities, data access, and provenance.
Review & attest
HLD reviews the server and issues a cryptographic attestation key. Think App Store review — but for MCP servers.
Verify at runtime
Cordon verifies the attestation on every connection. Unattested servers are blocked or flagged, per your policy.
// category of one
The first managed MCP security gateway.
Others sell software and hand you the keys — you configure it, you run it, you carry the operational burden. Cordon is a managed service: HLD deploys, monitors, and operates the security layer for you.
And it stays what it is — an MCP security gateway, defensible and specific, not another generic “AI oversight platform.”
self-managed gateways
You install it. You configure the policies. You watch the dashboards. You respond at 3am. Your team becomes the security operations team for your agents.
hld cordon — managed
HLD deploys the gateway, tunes the policies with you, monitors it continuously, and operates it end to end. You get the control plane; we carry the pager.
// roadmap
Gateway first. Accountability next. Enforcement everywhere.
MCP Gateway
Interception, inspection, and policy enforcement on every MCP tool call — deployed, monitored, and operated by HLD.
- Tool-call interception & inspection
- Policy enforcement at the gateway
- Attestation-backed server identity
Agent Registry
Every agent gets a named owner, a cost line, and a place in the org chart. Accountability, not just observability.
- Named agent owners
- Per-agent cost tracking
- Org-chart accountability
Full Enforcement
Organisation-wide policy enforcement, anomaly detection, and compliance reporting across your entire agent fleet.
- Full policy enforcement
- Anomaly detection
- Compliance reporting
