Gartner defines access management (AM) as tools that include authentication and single sign-on (SSO) capabilities, and that establish, manage and enforce runtime access controls for modern standards-based and classic web applications and APIs. AM’s purpose is to enable SSO access for people (employees, consumers and other users) and machines to protected applications in a streamlined and consistent way that enhances the user experience. AM is also responsible for providing security controls to protect the user session in runtime, enforcing authentication and authorization using adaptive access. Lastly, AM can provide identity context for other cybersecurity tools and reliant applications to enable identity-first security.
Gartner defines identity governance and administration (IGA) as the solution to manage the identity life cycle and govern access across on-premises and cloud environments. To accomplish this, IGA tools aggregate and correlate disparate identity and access rights data, and provide full capability controls over accounts and associated access. IGA solutions also fulfill the purpose of unifying and correlating identity data for organizations with multiple person and machine identity authoritative sources. This is done to provide a single view of identity (system of record) for their dependent processes and systems
