Windows Server CALs – Access licenses for users & devices

Windows Server CALs (Client Access Licenses) are required to grant users or devices legitimate access to a Windows Server. They complement the actual server license and are necessary regardless of the chosen server edition (Standard or Datacenter).

In this category you will find Windows Server CALs for users and devices , clearly and concisely labeled. These licenses are suitable for both small networks and professional enterprise environments with multiple access points.

Compatibility:

Windows Server 2025 CALs are backward compatible and can also be used for Windows Server 2022, 2019, and 2016. This allows existing infrastructures to be flexibly expanded without having to maintain separate CALs for each server version.
