1Password Extended Access Management vs Shush Network Authentication: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise security teams with identity sprawl across SaaS and on-premises systems should pick 1Password Extended Access Management for its ability to enforce least-privilege access without requiring directory infrastructure overhaul. The platform scores strongly on NIST PR.AA and DE.CM, meaning it detects unauthorized access attempts and anomalous behavior in real time rather than waiting for a breach to surface. Skip this if your organization runs a tightly controlled, single-directory environment where access is already audited; the tool's strength lies in managing messy, distributed identities where traditional PAM tools fall short. Mid-market and enterprise security teams replacing SMS OTP with something actually resistant to SIM swaps will find Shush Network Authentication worth the deployment effort. It eliminates the user friction that kills adoption of traditional MFA by authenticating silently through carrier network data instead of app prompts or codes, and the SIM-to-device duration checks catch the swap attacks that SMS cannot. Skip this if your organization needs authentication to work across international roaming scenarios or requires deep integration with existing identity platforms; Shush's MNO-dependent model has real geographic constraints.
