What is user access management, and why does my business need it?

User access management is the set of policies, processes and technologies used to control who can access which systems, applications and data within your organization. It covers how user accounts are created, what permissions they’re assigned, how those permissions change over time and how access is revoked when someone leaves. Without a structured approach, permissions accumulate unchecked, former employees retain access and your attack surface grows silently with every new hire.
