As a manager of an enterprise, I definitely hope that employees can work hard in the process of going to work and don't do things unrelated to work. In order to better manage employees' online behaviors, employees' computers in the local area network can be managed in a unified way through domain shields, and multiple employees' computers can be managed in a unified way on managers' computers, so that real-time screen images of multiple employees' computers can be known, and real-time screen videos and screen snapshots of computers can be saved, so that managers can audit employees' computer operation behaviors at any time and record employees' online behaviors in detail.
