Rublon SSO (Single Sign-On) is a cloud-based Single Sign-On portal that allows users to authenticate once and gain access to all integrated applications without repeated logins. Users access a centralized SSO Portal, from which they can launch any connected application with a single click. The solution supports both on-premises and cloud-based applications, as well as VPNs, servers, and admin tools. It is compatible with any application that supports SAML for authentication. Rublon SSO works alongside Rublon's Multi-Factor Authentication (MFA) product, allowing organizations to combine streamlined access with layered security rather than treating SSO and MFA as mutually exclusive. Authentication sources supported include Microsoft Active Directory, LDAP, and RADIUS. The product is delivered as a cloud service, requiring no hardware purchase or installation, and enrolls users automatically upon their first login. Rublon SSO is positioned to support regulatory compliance requirements including PCI DSS, ISO/IEC 27001, NYDFS, and NAIC standards.
