Cross-Company Trust for the AI Era
Verify identity. Enforce permissions. Audit interactions across organizations.
API-to-API | System-to-system | Agent-to-agent | Organization-to-organization
How it works
More than an AI kill switch, Masterkeys establishes enforceable trust between companies before autonomous actions take place.
Legacy security was built for humans logging in. It was never built for agents acting autonomously across company lines.
AI-assisted breaches now happen in minutes. Autonomous agents chain actions, access APIs, and transact across organizations — without a human checkpoint in sight. Token leaks, prompt injections, and misconfigured permissions aren't edge cases anymore. They're the attack surface. And your existing security tools were never designed to govern what's on the other side of your firewall.
And it's not just agents. Masterkeys governs any connection that crosses a company boundary — API to API, system to system — with or without an AI in the loop.
Masterkeys makes trust enforceable.
Identity
Every human, AI agent, workflow, and IoT device receives a cryptographic identity — a Masterkey — that is verifiable, non-spoofable, and portable across organizational boundaries. No more shared credentials. No more implicit trust.
Permissions
Authority is explicitly delegated, not assumed. Every agent operates within a scope that defines exactly what it can access, what it can do, and for how long. Permissions can be granted, narrowed, or revoked across companies in real time — without touching your existing stack.
Enforcement
Our lightweight Rust gateways intercept every action before it executes. Identity is verified. Permissions are checked against live policy. Anomalous behavior is flagged. If the check passes, the action proceeds. If it doesn’t, it’s blocked — before a single byte moves.
Proof
Every decision, permitted or denied, is written immutably to a cryptographic audit trail. Not a log file. A ledger. Audit-ready for partners, regulators, and insurers the moment a question arises.
When a node is compromised, one click revokes its access. The blast radius ends there. Everything else keeps running.
Data at rest and data in motion are established concepts. Masterkeys introduces the missing layer: Trust-in-Motion. Identity, permissions, enforcement, and proof — operating continuously, at machine speed, across every access event and organizational boundary.
No rip and replace. Running while others are still justifying the ROI.
