Computer and Network Security Zielona Gora, lubuskie 51–200 employees Founded 2001 Privately Held

Rublon delivers identity-centric access control via multi-factor authentication and passwordless login across hybrid infrastructure. The tech stack reveals a dual-track architecture: Java/Jakarta EE + Kubernetes for cloud services, paired with C++/Qt for Windows-native clients and Active Directory integration. Heavy R&D investment in WebAuthn, FIDO2, and passkeys signals a strategic pivot away from password-dependent flows—a shift reflected in the project roadmap's focus on passwordless MFA and zero-trust network access.
