Validate both ends.
Verify the gateway’s identity and the client’s certificate chain. Map the authenticated credential to the correct tenant, device, and access scope.

Enterprise connectivity.
Post-quantum confidence.
Protect traffic captured today from the quantum systems of tomorrow. Antara combines classical cryptography with standardized post-quantum algorithms and gives security teams one policy plane for every transition.

CRYPTO-AGILITY AT ENTERPRISE SCALEChange an algorithm.
Change an algorithm.
Keep the business moving.
Cryptographic policy belongs in the control plane. Move from inventory to canary deployment, fleet-wide enforcement, and rollback without rebuilding gateways or interrupting active work.
- Govern key exchange and identity independently
- Prevent silent downgrade to weaker algorithms
- Measure compatibility before fleet-wide rollout
CLIENT AND SERVER IDENTITYMutual trust.
Mutual trust.
Built for the next cryptographic era.
Antara Secure Access brings client certificates, gateway identity, and hybrid session protection into one access lifecycle. Govern the proof of identity as carefully as the encrypted path.
Separate proof from secret.
Use the approved signature profile for identity and hybrid ML-KEM key agreement for the session. Observe both negotiated results.
ML-DSA identity + hybrid transportKeep reconnects accountable.
Bind continuity to authentication age, credential validity, and current policy. Revocation and posture changes remain access decisions.
Renewal, revocation + session policyFROM THE ENGINEERING JOURNALKeep the proof.
Keep the proof.
Rethink the reconnect.
Explore the ML-DSA client mTLS research: why signatures stay intact, where certificate compression helps, and how a proposed bootstrap-and-resumption profile reduces repeated work.
STANDARDIZED PROOF2,420 bytes
An ML-DSA-44 signature.
The optimization is in the lifecycle.
ONE CONTROL PLANE
A complete migration path.
Post-quantum readiness spans transport, identity, and operations. Antara brings all three into one governed program.
