Our verdict on ARK2FA
ARK2FA is an on-premises, self-hosted multi-factor authentication product from WPROIT EOOD, founded in 2022. It is designed for organizations securing ADFS-protected applications, VPN access, Wi-Fi, and other RADIUS clients. The product supports web, Windows, and Linux environments, with authentication through SMS, OTP, TOTP, HOTP, Google Authenticator, and Microsoft Authenticator. A web-based management interface provides administration and access controls.
Pricing is organized around the ADFS Edition and Enterprise Edition, with licensing available through direct contact with WPROIT. The ADFS Edition includes an ADFS MFA adapter, SMS and OTP, authenticator app support, and the web management portal. Enterprise adds the ADFS features plus a RADIUS proxy for VPN and Wi-Fi, multi-vendor authenticator support, role-based admin delegation, comprehensive audit logging, and a 24/7 support SLA. Organizations comparing products will need to discuss licensing and edition fit with the vendor rather than selecting from public plan prices.
ARK2FA’s strongest fit is an existing Microsoft and network-access environment built around ADFS, RADIUS, LDAP, or supported VPN and Wi-Fi platforms. Listed integrations include Cisco AnyConnect, FortiClient, Pulse Secure, Aruba Wi-Fi, Cisco Wi-Fi, Google Authenticator, and Microsoft Authenticator. The product is a practical match for teams that want self-hosted control and established factor options across these systems. It is less suited to buyers seeking a free entry tier or a broader identity platform centered on other deployment models. Choose ARK2FA when ADFS and network-access MFA are the priority; consider alternatives when those systems are not central to the environment.
