Protectimus On-Premise MFA Platform is a self-hosted multi-factor authentication solution that organizations can deploy within their own infrastructure. Unlike the cloud-based variant, this platform runs entirely on-premises, giving organizations full control over their authentication data and environment. The platform supports a range of authentication methods and integrates with common enterprise systems including Active Directory (AD), LDAP, databases, RADIUS-compatible services, VPNs, and Microsoft services such as ADFS, Outlook Web App (OWA), and Office 365. Ready-to-use components are available for Windows and RDP logon, ADFS, OWA/Exchange Admin Center, Roundcube webmail, and RADIUS-based infrastructure. VPN support is provided via RADIUS, with compatibility noted for SonicWall, Sophos, Cisco, and Azure VPN. An additional Dynamic Strong Password Authentication (DSPA) component allows MFA to be added directly to AD, LDAP, and databases without modifying existing application code. The platform is suited for regulated and security-sensitive industries including financial services, healthcare, government, education, energy, technology, online gaming, and gambling sectors. Hardware tokens are also available as an authentication factor, with support for Electronic Visit Verification (EVV) use cases in healthcare.
