Protectimus MFA provides cloud and on-premise multi-factor authentication for teams and their customers. Authentication options include a mobile authenticator app, hardware OTP tokens, chatbots, SMS, email, and push notifications. Its cloud service is a ready-to-use SaaS option that avoids managing authentication equipment and infrastructure. On-premise deployment keeps user data, token secrets, and authentication logs within an organization’s infrastructure, with authentication traffic staying inside its network. Listed integrations include Active Directory, LDAP, Windows and RDP, RADIUS, OWA, ADFS, Roundcube, VPNs, Citrix, and Office 365 SSO. Developers can use a REST API that supports XML and JSON, plus Java, Python, and PHP libraries. Additional integration methods include an iFrame widget, plugins, and integration components. On-premise deployments support multidomain environments, clustering, replication, and backups. Protectimus says its solution is OATH-certified and that it is an OATH coordinating member. Plans include a free option for 10 users and paid options; the Custom plan is $2 a month, billed per user.
