Cryptographic identityfor machines.

TKeeper is the cryptographic identity of an agent, service, or workflow. Every critical action is bound to intent, policy, quorum, and proof.

Machine securitystarts with identity.

Each TKeeper is built for one job. Choose the authorities and cryptography it needs; everything else stays out. New integrations take less work without weakening security.

Cryptographic identity

AI Agents

Secure agent identity, tool calls, agentic payments, and production actions with policy and proof before execution.

Digital Assets

Add policy-controlled EVM and Bitcoin flows without building separate signing infrastructure for every product.

PKI & X.509

Put policy in front of X.509 signing while keeping the CA and certificate workflow you already run.

Critical Infrastructure

Turn privileged commands and external risk verdicts into cryptographic conditions your backend must verify.

Governance ispart of theidentity.

The applied manifest defines the exact actions this identity can authorize. Permissions, policy, approvals, custody, and audit govern every use of its key.

So simple to integrate.

Just put TKeeper between the machine and your backend, then verify the returned proof before execution.

Compromise doesn'tgrant control.

A single TKeeper identity can run across independent parties instead of concentrating operational risk in one machine. Multi-Party Computation (MPC) lets you share risk across teams, systems, and organizations with a configurable quorum that defines compromise tolerance.

Every identity is inventoried.Every governed action is logged.

Post-quantum without starting over.

Move to ML-DSA when you need to. Your identity, policy, controls, and integrations remain intact.

So, you canlet machines act.

Governance without cryptographic enforcement is wishful thinking. TKeeper was built for peace of mind in the age of autonomous machines: identity, policy, and distributed authority are cryptographically bound to every action.

Fits any machine workflow.
Keeps risk distributed.
Enter new markets faster.
Compliance stays verifiable.
Post-quantum migration costs less.
