An external user is someone who is not a part of the organization or entity that owns or operates the IT system.
These users may include customers, clients, vendors, suppliers, or partners who use the IT system to interact with the organization.
External users may access systems through channels such as internal applications, APIs, web portals, mobile apps, or other online services.
Since external users may have different permissions and levels of access, their activities on the system may need to be more closely monitored and controlled to ensure the security and privacy of the organization's data and systems.
