Rublon Multi-Factor Authentication
Startups and mid-market companies needing MFA without the sprawl of enterprise IAM platforms should move fast on Rublon Multi-Factor Authentication; its push notification and passkey support eliminate the friction that kills adoption, and automatic enrollment on first login means you're not managing onboarding manually. FIDO2 and RADIUS integration for VPN access cover the two deployment scenarios that actually matter for teams splitting time between office and remote. Steer clear if your org has already standardized on Okta or Azure AD for SSO; Rublon's strength is MFA acceleration, not replacing your identity platform.
Mid-market and enterprise teams managing multiple identity systems across on-premises and cloud will value Forum Sentry Mobile Identity for its protocol-agnostic translation layer, which eliminates the ramp-up cost of retrofitting legacy authentication into modern SSO without per-user licensing. The platform handles any-to-any format conversion,HTTP Basic to OAuth, PKI to SAML, proprietary tokens to JWT,which saves months of integration work when you're inheriting fragmented auth stacks. Skip this if you're looking for a modern identity platform from scratch; Forum Sentry is a bridge tool, strongest when you have existing systems that need to talk to each other.
