Access management decides who can sign in to which application and what they can do inside it. How it works, where it stops and how it differs from IAM.
November 2, 2026
Access management is the operational part of identity and access management that decides, at the moment of access, whether a person or a system may use an application and what it may do there. It covers authentication, authorization, the policies applied at sign-in, and the granting and removal of rights. Identity and access management is the umbrella; access management is the part that acts in real time.
The three terms describe layers of the same problem. Identity and access management is the whole field. Access management is the enforcement layer: it lets the right person in and keeps everyone else out, request by request. Access governance sits above it and answers a different question, whether the access that exists today is still justified, through reviews, certifications and audit evidence.
The distinction matters for compliance. Article 21 of the NIS2 Directive lists access control policies among the cybersecurity risk-management measures, and multi-factor authentication where appropriate. Enforcing those rules at sign-in is access management; demonstrating them to an auditor is governance.
A 250-person software company uses Microsoft Entra ID for single sign-on to 40 applications and enforces MFA at every sign-in. On paper, access management is solved. In practice, the finance team pays for 15 more tools with their own logins, and engineering runs a monitoring tool where accounts are created by hand. None of those sign-ins go through the identity provider, so none of its policies apply, and a departure processed in Entra ID leaves those accounts open.
Corma extends access management to that part of the stack. It discovers the SaaS applications in use, connects to the identity provider and automates provisioning and deprovisioning across applications, including those without SCIM, so that granting and removing access follows the same workflow everywhere.
IAM is the whole field, from creating identities to governing them. Access management is the part that authenticates users, authorizes them and enforces policy each time they open an application.
Not quite. Access control is the mechanism that allows or denies an action, such as a role or a permission list. Access management is the wider process that sets up, applies and maintains those controls over time.
Identity providers with single sign-on and MFA, privileged access management tools, and platforms that automate provisioning and access requests across SaaS applications.
Only if something manages them. Applications with local logins are invisible to the identity provider, so their accounts have to be discovered and managed directly, which is the job of SaaS management and automated deprovisioning.
