Orchestration. Management.Observation.
Enterprise scale deployment means managing users, keys, and their access to enroll in different levels of trust. What about adjusting security settings or exporting audit logs? That’s the power that Citadel’s admin portal puts at your finger tips.
Trust. Authority. Identity.
Bring proof-of-identity to the key with your certificate authority (CA) or Citadel’s. A key signed by the CA creates cryptographic trust between it and the accounts that it unlocks. We do the heavy lifting for certificate issuing, management, revocation, and renewals.
We only use frameworks that are best in class
We only implement authentication that complies with standards like FIDO2 and PIV
under NIST which are the benchmark for secure authentications.
