Duo Adaptive Access vs Silverfort Universal Multi-factor authentication: 2026 Comparison

Duo Adaptive Access

Teams protecting distributed workforces will find Duo Adaptive Access most valuable for its risk-based decision engine that actually blocks access before compromise rather than logging it afterward. The push to continuous authentication and real-time threat detection maps directly to NIST CSF 2.0's Identity Management function, meaning your access controls adapt to actual risk instead of static rules. Skip this if you need device inventory and vulnerability correlation; Duo assumes your devices are already managed elsewhere.

Silverfort Universal Multi-factor authentication

Organizations protecting legacy applications and OT systems should pick Silverfort Universal Multi-factor authentication because it enforces MFA without code changes or agent deployment, a constraint that kills most competitors in these environments. The agentless architecture extends MFA to Kerberos, NTLM, LDAP, and command-line tools that modern solutions simply skip over, backed by risk-based enforcement tied to real-time threat signals for adaptive policy. Skip this if your infrastructure is cloud-native and you need MFA as one layer of a broader identity platform; Silverfort is deliberately built for the hard authentication problems that on-premises environments create.
