What Rublon does
Rublon sp. z o.o. is a Poland-based (Zielona Góra HQ, Kraków engineering office) cybersecurity vendor founded in 2000 that released its flagship multi-factor authentication platform, Rublon MFA, in 2018. The platform secures employee access to networks, servers, applications, VPNs, RDP/VDI sessions, cloud SaaS, and Linux SSH by requiring a second authentication factor (Mobile Push, TOTP, FIDO2/WebAuthn security keys, SMS, phone call, email link, QR code) on top of standard passwords, with an EU-hosted administration console. Rublon is not an Identity Provider; it augments existing identity systems via a broad connector and protocol stack — Active Directory, Entra ID, AD FS, RADIUS, LDAP, SAML 2.0 — plus dedicated plugins for Windows Logon/RDP, RD Gateway, OWA, Atlassian Jira/Confluence, WordPress, Veritas NetBackup, and Roundcube, with Java/PHP/.NET SDKs for custom integrations. Recent agentless offerings (Rublon App Shield, Rublon Identity Bridge) extend coverage to applications that cannot host endpoint agents.
The company operates a per-user subscription model (annual or monthly billing) with a self-serve 30-day free trial and a freemium single-user tier, supplemented by a quote-based enterprise sales motion and a Partner Program targeting Managed Service Providers. Go-to-market blends product-led growth (PLG) for SMBs with channel and direct enterprise sales. Rublon serves 500+ customers across 50+ countries, including G4S, Eurofins, Harris, Carpenter, Nordlo, and OEBK, addressing verticals from financial services and healthcare to government, manufacturing, and legal. The company is privately held, bootstrapped (share capital PLN 200,000), with disclosed EU regional co-funding in 2017 (~USD 125K) and 2025 (~USD 865K), and is ISO 27001:2023 certified with GDPR, NIS2, DORA, HIPAA, PCI DSS 4.0, and NIST SP 800-63 alignment.

Rublon product offering
Product offeringCore offering
Rublon develops and sells Rublon MFA, a cloud-managed multi-factor authentication platform that protects employee logins to networks, servers, endpoints, cloud applications, VPNs, RDP, and on-premise systems. The offering is delivered through the Rublon Admin Console and a portfolio of connectors (Windows Logon & RDP, Linux SSH, AD FS, RADIUS/LDAP Proxy, SAML Access Gateway, plus plugins for Jira, Confluence, WordPress, OWA, RD Gateway, Veritas NetBackup, and Roundcube), with the Rublon Authenticator mobile app serving as the primary second factor.
Product overview
Rublon is a cybersecurity company offering Rublon MFA, a unified multi-factor authentication platform for enterprise workforce protection. The portfolio consists of the core Rublon MFA platform (managed via the Rublon Admin Console) supported by a broad ecosystem of connectors, add-on modules, and supplementary tools. The Rublon Authenticator mobile app serves as the primary second factor across all integrations. Connectors extend MFA to specific technologies: Rublon MFA for Windows Logon & RDP and Linux SSH handle workstation/server login; Rublon Authentication Proxy handles RADIUS/LDAP-based integrations (VPNs, VDI); Rublon Access Gateway handles SAML-based cloud app integrations; and dedicated plugins cover Jira, Confluence, WordPress, Outlook Web App, AD FS, Remote Desktop services, Veritas NetBackup, and Roundcube. Rublon App Shield and Rublon Identity Bridge provide agentless MFA for applications without endpoint agents. Directory Sync enables AD user/group synchronization. The platform supports diverse authentication methods including Mobile Push, TOTP, FIDO2/WebAuthn security keys (YubiKeys, passkeys), SMS, phone calls, email links, and QR codes. Rublon MFA is not open-source and is not an Identity Provider — it augments existing IdPs and identity systems. Deployment is cloud-managed (with EU-based infrastructure), hybrid, or on-premise components.

Rublon competitors and assessment
Company assessmentEmerging players
- Yubico: Yubico manufactures the YubiKey hardware authenticators and offers Yubico Enterprise Services for FIDO-based authentication. Overlaps with Rublon on FIDO2/WebAuthn phishing-resistant authentication and is integrated via YubiKey OTP support in the Rublon platform.
- Twilio Authy: Authy (Twilio) provides TOTP-based two-factor authentication for end users, with mobile app and backup capabilities. Comparable as a consumer/SMB-focused MFA authenticator, with less enterprise integration depth than Rublon.
- Silverfort: Silverfort delivers identity threat protection and MFA for on-prem and hybrid environments (AD, VPNs, legacy systems) via a unified layer. Comparable with Rublon's on-prem MFA connectors (Windows, AD FS, RADIUS, LDAP) but with broader identity threat detection scope.
- HYPR: HYPR specializes in passwordless and phishing-resistant MFA using FIDO2 and decentralized authentication. Comparable focus on modern authentication methods and enterprise workforce protection, with similar emphasis on FIDO2/WebAuthn as Rublon's hardware authentication.
- Beyond Identity: Beyond Identity provides passwordless, risk-based authentication using device-bound credentials and continuous identity verification. Competes with Rublon in phishing-resistant workforce MFA, particularly for organizations prioritizing passwordless transitions.
Broad incumbents
- Microsoft Entra ID: Microsoft Entra ID (formerly Azure AD) bundles MFA into the broader Microsoft 365 and Azure ecosystem. Overlaps with Rublon on Windows logon, RDP, AD FS, and cloud app MFA, and represents the primary bundled-incumbent threat to independent MFA vendors.
- Okta: Okta is a leading identity and access management platform offering MFA, SSO, and adaptive authentication as part of its Workforce and Customer Identity Clouds. Closest direct overlap on enterprise MFA, with broader identity governance and lifecycle management reach than Rublon.
- Cisco Duo Security: Cisco Duo is a leading cloud-delivered MFA and zero-trust access platform, now part of Cisco Secure Access. Direct overlap with Rublon on enterprise workforce MFA, push/TOTP/FIDO2 methods, SSO, and broad application integration, but operates as part of Cisco's larger security portfolio.
Direct peers
- LastPass MFA (GoTo): LastPass MFA by GoTo delivers adaptive, biometric MFA for workforce applications and single sign-on. Comparable mid-market/enterprise MFA positioning with similar authentication methods (push, biometrics, FIDO) and broader password management adjacency.
- ManageEngine ADSelfService Plus: ManageEngine ADSelfService Plus offers MFA, SSO, and self-service password management for Active Directory and enterprise apps. Direct overlap with Rublon on AD-integrated MFA, with broader password self-service capabilities and a large existing Zoho/ManageEngine install base.
