GateKeeper Enterprise vs Protectimus On-Premise MFA Platform: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise teams protecting shared or high-touch workstations should consider GateKeeper Enterprise for its proximity-based automatic lock-unlock, which eliminates the friction of manual MFA while maintaining audit trails on who accessed what. The on-premises deployment with SQL-backed credential storage and Active Directory integration appeals to organizations with strict data residency requirements, and the NIST PR.AA coverage reflects solid identity and access control enforcement. This is not the right choice if you need cloud-native SSO, browser extension support across all applications, or cloud-hosted credential management; GateKeeper's strength is physical workstation security for defined user populations, not distributed workforce scenarios. Mid-market and enterprise security teams that require full infrastructure ownership and need MFA across legacy systems should evaluate Protectimus On-Premise MFA Platform; self-hosted deployment gives you control over authentication data and eliminates cloud vendor dependencies, which matters for regulated industries handling sensitive access logs. Its RADIUS support and pre-built connectors for Windows RDP, Active Directory, and VPNs mean you can deploy MFA to network equipment and remote access without rebuilding authentication workflows. Skip this if you're cloud-first and want a modern SaaS MFA provider with passwordless-native design; Protectimus trades modern UX for infrastructure autonomy.
