Markmonitor Single Sign-On (SSO) is an authentication solution that provides centralized access control for the Markmonitor Domain Management Portal. The product eliminates the need for multiple login credentials by integrating with existing identity providers. The solution supports SAML 2.0 protocol for identity federation, enabling organizations to use their existing identity infrastructure. It provides centralized authentication management, which consolidates user access control into a single system. The product addresses user lifecycle management by streamlining both onboarding and offboarding processes. When employees join or leave an organization, access can be provisioned or revoked through the central identity provider rather than managing separate credentials for the domain management portal. Markmonitor SSO enhances compliance oversight by providing centralized visibility into user access patterns and authentication events. This centralized approach supports audit requirements and security monitoring activities. The solution integrates with the Markmonitor Domain Management Portal, which is used for corporate domain registration and management services. Organizations can maintain their existing SAML 2.0 identity providers while adding secure access to domain management capabilities.
