Green Rocket Security

What Green Rocket Security does

Green Rocket Security Inc., founded in 2014 and headquartered at 1900 Camden Ave., San Jose, California, is a privately held software vendor that builds GreenRADIUS, an on-premise multi-factor authentication (MFA) server. The platform delivers two-factor authentication (2FA) for Windows Logon, VPN, Linux logins, network equipment, Microsoft ADFS, and web applications via RADIUS, LDAP, SAML 2.0, FIDO U2F, and OATH protocols, supporting tokens and authenticators including YubiKeys, Google Authenticator, Microsoft Authenticator, and Authy. The product runs on a hardened Ubuntu Server OS, supports high-availability clustering, and can be deployed on-premise or in AWS; GreenRADIUS v4.0 (September 2019) introduced FIPS 140-2 compliance and containerization, and the company holds US Government end-use licensing under FAR 12.212 and DFARS 227.7202.

The company monetizes through three streams: an annual per-seat GreenRADIUS software subscription that auto-renews with 90-day cancellation notice, resale of YubiKey hardware tokens through its long-standing partnership with Yubico (established August 2014), and a portfolio of premium add-on modules covering FIDO U2F, OATH, LDAP Authenticator, Mobile App (iOS/Android), PIN, Windows Logon MFA, ADFS, and YubiKey OTP validation. Pricing is quote-based and not publicly disclosed; the company offers free trial downloads and distributes through direct enterprise sales and authorized reseller partners, targeting federal agencies, law enforcement, healthcare, financial services, education, SMB, managed service providers, professional services, and remote access use cases. Named customers include the US Army, the University of South Florida, and unnamed federal, healthcare, and financial institutions, with the team originally responsible for the predecessor YubiRADIUS product. The company operates without disclosed external funding, has 11-50 employees, and continues to ship platform updates (v6.1.14.14 in June 2026) and security patches.

Broad incumbents

• Okta: Market-leading cloud identity and MFA vendor serving enterprise, federal, and education segments with a vastly broader suite. Competes with Green Rocket for the same buyer and use case (MFA, SSO, ADFS replacement) but at significantly greater scale and with SaaS delivery.
• RSA Security (SecurID): Long-established on-premise MFA and identity provider with strong federal and defense footprint via SecurID tokens and the RSA Authentication Manager. Competes with Green Rocket in the same government, defense, and regulated-account segment.
• HID Global (ActivID / Identity & Access Management): Authentication and identity vendor offering hardware tokens and IAM/MFA solutions for enterprise and government. Comparable because HID sells both YubiKey-equivalent authenticators and authentication server software competing for the same MFA budgets.
• Microsoft Entra ID (Azure AD / Microsoft Authenticator): Microsoft's identity, MFA, and SSO platform tightly integrated with Office 365 and ADFS — overlapping directly with GreenRADIUS's ADFS plugin and SAML 2.0 SSO use cases and often displacing standalone MFA vendors via bundled licensing.

Direct peers

• SecureAuth: Identity and MFA vendor offering adaptive MFA, SSO, and passwordless authentication for enterprise. Directly comparable on MFA product surface and target verticals (financial services, healthcare, government) to GreenRADIUS.
• Twilio Authy: Cloud-delivered 2FA mobile authenticator listed among the exact tokens GreenRADIUS OATH Module supports (Google Authenticator, Microsoft Authenticator, Authy). Competes for the same end-user soft-token use case but with a cloud, consumer-leaning model.
• Cisco Duo Security: Cloud-delivered MFA/2FA platform widely used by enterprise and education buyers. Green Rocket itself publishes a GreenRADIUS vs Duo Security comparison, underscoring direct head-to-head competition across the same 2FA use cases for regulated and mid-market customers.

Others

• Yubico: Strategic technology partner (since August 2014) and authorized reseller relationship for YubiKey hardware tokens. Although not a direct MFA-software competitor of GreenRADIUS, Yubico's own enterprise YubiEnterprise and YubiKey-as-a-Service products overlap with adjacent identity and FIDO use cases.

Emerging players

• ManageEngine (Zoho) — ADSelfService Plus / Endpoint MFA: Hybrid on-premise/cloud MFA and self-service password management focused on SMB and mid-market with strong Active Directory integration. Overlaps with GreenRADIUS's Windows Logon and ADFS-style use cases for cost-conscious regulated buyers.
• Keycloak (Red Hat build): Open-source identity and access management platform supporting 2FA, SSO, and federation on-premise. Relevant peer for buyers evaluating self-hosted authentication stacks similar in deployment topology to GreenRADIUS.
