What is OpenOTP Security Suite?

The OpenOTP Security Suite is a robust enterprise-level solution tailored for two-factor authentication through U2F/OTP, along with federation and identity management (IAM). This innovative system merges mobile technology with established security protocols, making it an excellent choice for both commercial and personal users seeking economical solutions that enhance user mobility. It also supports the integration of various third-party products and systems with multi-factor authentication (MFA), even when they solely rely on LDAP for authentication. If you are exploring options in user mobility, privacy, VPN and Wi-Fi security, single sign-on (SSO) and ADFS, fine-grained authentication policies, comprehensive security solutions, or European data storage, OpenOTP Security Suite could be the perfect fit for your needs. Additionally, it is designed for deployment either on-premises or within a private cloud environment, catering to various organizational requirements. The suite also offers a free token application compatible with most existing hardware and software tokens, a complimentary 30-day trial, and is available as freeware for organizations with fewer than 25 users.

What is Duende IdentityServer?

Security infrastructure sits at the heart of modern software, yet most solutions force organizations into an uncomfortable tradeoff: accept vendor lock-in or compromise on security to gain flexibility. Duende IdentityServer resolves that tension. Our platform delivers robust, standards-aligned identity infrastructure built ground-up for .NET by recognized experts and contributors to foundational security protocols — among them OpenID Connect, OAuth 2.0, Backend for Frontend (BFF), and FAPI. Developers get extensive customization by design — complete ownership of the UI, business logic, and deployment environment — paired with the licensing transparency and predictable cost structure that compliance-driven industries like finance and healthcare require. When you need to integrate reliable, modular identity into your stack without sacrificing control or technical depth, Duende is the trusted foundation. We bring the expertise to identity infrastructure, freeing you to invest yours where it matters most.
