Protectimus MFA for ADFS vs Rublon Multi-Factor Authentication: Side-by-Side Comparison (2026)

Protectimus MFA for ADFS

Organizations with Active Directory Federation Services deployments who need MFA without ripping out their existing auth stack should evaluate Protectimus MFA for ADFS; it plugs directly into ADFS as a ready-to-use component rather than forcing a platform migration. The tool covers NIST CSF 2.0 PR.AA identity management and supports both on-premises and hybrid cloud setups, making it viable for SMBs through enterprises. Skip this if you're standardizing on modern cloud identity platforms like Entra ID and want to deprecate ADFS entirely.

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.
