For example, customers of the company cannot even tell whether the employee is at work in the company or in their home office. Before installing a VPN, it is important to be familiar with the different implementation methods:. Software must be installed for standalone VPN clients. This software is configured to meet the requirements of the endpoint. When setting up the VPN, the endpoint executes the VPN link and connects to the other endpoint, creating the encryption tunnel.
