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:
SMB and mid-market IT teams managing hybrid infrastructure will find ESET Secure Authentication's mobile-first push authentication cuts password fatigue without requiring a security overhaul; the biometric support and on-premises deployment option mean you're not forced to choose between usability and control. NIST PR.AA coverage confirms the core access control story. Skip this if you need deep cloud-native IAM orchestration or plan to retire all hardware tokens immediately; ESET's strength is protecting legacy VPN and web app access, not replacing your identity fabric.
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.
