Microsoft CALs are a key component for managing enterprise networks that use Microsoft server software. If your company uses products such as Windows Server, Exchange Server or SQL Server, you will need these licences to allow users or devices to access server services. Although not as well known as other software licences, CALs are essential for managing enterprise environments efficiently and securely.

What are Microsoft CALs?

CALs (Client Access Licenses) are permissions that authorise users or devices to legally access services on a Microsoft server. Unlike standard licences, CALs do not allow you to run the software itself, but enable you to connect to and use the services offered by the server. It is important to remember that in order to comply with Microsoft’s policies, each user or device connecting to the server must be covered by a CAL.

For example, if your company uses Windows Server, each employee who wants to access the server’s resources will need a user CAL or a device CAL. This ensures that both the company and employees comply with Microsoft licensing regulations, avoiding penalties or legal issues in the future.

An important aspect to consider is the versioning of CAL licences, which allows access to systems of the same or earlier versions, but not to later versions. For example, when purchasing Windows Server 2019 User CAL licences, you will be able to access servers with Windows Server 2019, Windows Server 2016 or Windows Server 2012, but not one with Windows Server 2022.

Types of CALs

USER CAL

User CAL licences are associated to each user that accesses the server, using services such as printing, storage, among others, regardless of the device they use.

This is the most suitable option for companies where users access the corporate network from several devices or when the devices are not always the same. With this type of CAL, you can save on costs if the number of devices is greater than the number of users.

DEVICE CAL

This type of licence is associated with a specific device. Instead of licensing users, the machine is licensed, regardless of how many users use it.

This option is ideal for companies where there are more users than devices, such as in a contact centre, where several employees use the same machine on different shifts.
