Brief overview

The Microsoft SQL Server 2025 Device CAL (Client Access Licence) is an access licence that authorises a specific end device to access the features and services of an SQL Server. It is provided as a perpetual licence to supplement an existing server installation under the Server/CAL licensing model.

Applications / Benefits

This licence is used to enable a physical device – such as a desktop PC, laptop or terminal – to access SQL Server databases in a legally compliant manner. It facilitates efficient licensing in work environments where multiple users take turns using the same device, such as at checkout counters, in shift-based operations or at publicly accessible stations.

Features & Scope of Services

The scope of services includes authorisation for the licensed device to access an unlimited number of SQL Server instances within the organisation, provided these have the appropriate server version. The Device CAL is version-specific and backwards compatible, enabling access to older SQL Server versions. It does not contain any software bitstreams, but merely represents the right of use.

Target Audience

The product is aimed at companies and organisations that operate their database infrastructure using the server/CAL model and prefer device-bound licensing to optimise licensing costs when hardware is used multiple times.

The Device CAL is the ideal solution for working environments where several employees share a single device, such as at workstations in production, at point-of-sale systems or in shift-based operations. As the licence is tied to the device, any number of users can access SQL Server 2025 from this hardware in turn, without the need for a separate licence per user.
Yes. When you purchase the SQL Server 2025 Device CALs, you are granted the right to downgrade. This means that you can also use these licences to access older SQL Server instances (e.g. 2022, 2019 or 2017) on your network. This makes the package a future-proof investment for your existing and future database infrastructure.
Under the NIS 2 Directive, precise documentation of network access is crucial. For every device CAL, we provide you with a comprehensive compliance portfolio, including a complete chain of custody. This enables you to demonstrate to auditors and regulatory authorities that access to your critical databases is granted via lawfully acquired and documented asset licences.
Standard Access Licences (CALs) for SQL Server are organisational licences. They do not need to be activated by entering a key into the system. Legal certainty is ensured by the provision of licence proof, which we supply to you in a digital, audit-proof format. This forms the basis for any software asset management (SAM) and protects you in the event of audits by the manufacturer.
An invoice is automatically generated for every order. You will receive this by email and can download it at any time from your customer account.
