The passwordless authentication platform
Citadel
Citadel is more than a platform: it's a promise that every interaction is undertaken by a verified, trusted user. Manage the full lifecycle of your authenticators, whether security keys or device biometrics, and handle any kind of workflow for user enrollment and offboarding. Protect your infrastructure with MFA that can't be spoofed, phished, or stolen.
Citadel powers strong authentication
Make every endpoint a fortress. Tie into all your systems and enforce passwordless MFA.
Credentials are the keys to your crown jewels. Don't take chances.
Protect all keys with TPMs
Citadel enforces authentication with YubiKeys or device biometrics native to Apple and Windows; their Trusted Platform Modules (TPM) are designed to protect private keys.
Adopt the highest standards
Citadel enforces FIDO2 and PIV standards instead of other "phishing resistant" methods. FIDO2 and PIV are widely regarded as the highest bar for secure authentication.
Integrate everywhere
Integrate with your enterprise infrastructure and identity provider to get strong authentication and proof-of-identity across the most sensitive areas of your workplace.
Host it where you want
Citadel’s cloud-native architecture and built in certificate authority makes deployment fast and drives down costs. It can also be self hosted, or completely air gapped with your own certificate authority.
Use a variety of authenticators
Citadel works with all YubiKey models and the device biometrics on Windows, Apple, and Android. It can also integrate with CAC cards and other security keys that meet requirements for PIV and/or FIDO2.
Give users a great experience
Deliver a better user login experience while increasing security. Citadel is built for a fast and native experience every time a user logs in or enrolls new authenticators.
