Compare features, ratings, integrations, and community reviews side by side to find the best multi-factor authentication and single sign-on fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams standardizing on vendor-agnostic authentication will find AccessMatrix UAS valuable for avoiding lock-in while supporting biometrics, FIDO2, and hardware security modules in parallel. The platform handles 100 million plus user scale and integrates with token vendors from OneSpan to Thales without custom engineering, which matters when you're already managing heterogeneous hardware across regions. Skip this if your organization needs out-of-the-box connectors to your existing identity provider; AccessMatrix is an authentication server, not a replacement for your IAM platform.
Startups and mid-market teams building custom applications need Keycloak because it's open-source IAM you can actually modify without vendor lock-in, and self-host it on infrastructure you already control. The tool supports OAuth 2.0, OpenID Connect, and SAML protocols out of the box, plus passkey-based MFA and multi-tenancy through its Organizations feature, covering NIST CSF 2.0's Identity Management function without licensing per user. Skip this if your organization needs managed SaaS convenience and hands-off operations; Keycloak requires DevOps capacity to deploy, patch, and maintain in production.
