Rublon

Rublon (short for Real User Business Logon) is a Poland-based cybersecurity company, part of Astec Group, that provides multi-factor authentication (MFA) and single sign-on (SSO) solutions for organizations. Founded in 2011, the company originally launched as a passwordless login solution using smartphones as authentication tokens, before evolving into an enterprise-focused authentication platform in 2018. Rublon's core product is its MFA platform, which supports authentication across a range of environments including Windows endpoints, VPN connections, servers, and applications. The platform offers multiple authentication methods, including mobile push notifications via the Rublon Authenticator app, QR code-based authentication, and TOTP. Integrations are delivered through native connectors such as Rublon for Windows and the Rublon Authentication Proxy, which supports RADIUS-based VPN systems. Administration is managed through a browser-based Rublon Admin Console, allowing IT teams to configure security policies, manage users and groups, and monitor access across the organization. The platform is designed to scale and supports deployment for additional applications and users without significant infrastructure changes. Rublon targets organizations of various sizes, including small-to-medium businesses and enterprises, across industries such as manufacturing, finance, and technology. A key use case includes helping organizations meet compliance requirements such as the EU NIS2 Directive, which mandates MFA implementation for entities classified as important or essential under the regulation. The company's R&D division, Rublon Labs, was established in 2015 and focuses on cryptography and authentication research, with several patented innovations. Rublon is headquartered in Zielona Gora, Poland.
