Beyond Identity Phishing-Resistant MFA vs Duo Adaptive Access: Side-by-Side Comparison (2026)

Beyond Identity Phishing-Resistant MFA

Startups and mid-market companies tired of phishing attacks against SMS and TOTP codes should build their access layer around Beyond Identity Phishing-Resistant MFA, which eliminates those fallback factors entirely through cryptographic key-based authentication tied to device trust. The platform covers NIST PR.AA (identity and access control) and DE.CM (continuous monitoring) without requiring you to bolt on separate device posture tools; Intune and CrowdStrike integration handles that natively. Skip this if your organization relies heavily on legacy applications that can't handle modern authentication protocols or if you need deep SSO analytics beyond basic provisioning.

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.
