Identity governance (also known as "IGA") is the policy-based centralized orchestration of user identity management and access control. Identity governance helps support enterprise IT security and regulatory compliance.
Privileged access management (PAM) software helps companies protect the “keys to their IT kingdom" by ensuring the credentials of their privileged accounts, such as admin accounts on critical company assets, are only accessed by those with proper permissions to do so. PAM software helps prevent external hacking or internal misuse of important company assets by employing “least privilege access" policies, wherein users receive the absolute minimum access needed to perform their duties.
