CST VerdictShort answer
Mid-market and enterprise teams standardized on Microsoft Entra ID but tired of password fatigue should evaluate PortalGuard for its passwordless biometric authentication, which actually works across desktop login, mobile, and web portals without forcing users back to OTP as a fallback. The platform supports 16 authentication methods and integrates directly with Entra ID, so you're not ripping out identity infrastructure. The honest limitation: PortalGuard prioritizes access control over detection and response, so if your team needs deep behavioral analytics or anomaly detection built into your IAM layer, you'll need a separate investment there. Mid-market and enterprise teams handling PSD2-regulated transactions or managing high-risk user populations will find MIRACL Trust® MFA's zero-knowledge proof architecture genuinely harder to compromise than PIN-based or OTP competitors, since credentials never exist in transmissible form. The ISO/IEC-approved M-Pin protocol and Distributed Trust Authority design eliminate the credential database compromise that haunts traditional MFA vendors. Skip this if you need broad OIDC federation out of the box or plan to deploy across devices you can't control; the rooted device restrictions and SDK-first integration model demand more engineering overhead than cookie-cutter MFA solutions.
