AccessMatrix UAS is a commercial multi-factor authentication and single sign-on tool by i-Sprint Innovations. UserLock is a commercial multi-factor authentication and single sign-on tool by IS Decisions. 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.
CST VerdictBased 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.
SMB and mid-market teams managing on-premises or hybrid Active Directory environments need UserLock for context-aware access control that blocks compromised credentials even after MFA bypass. The tool maps directly to NIST PR.AA by enforcing device posture and location checks before granting logon, not just at initial authentication. Skip this if your infrastructure is cloud-native or you lack Active Directory as a core identity system; UserLock's value collapses without AD to anchor on.
