Windows Server 2025 CALs – User & Device Access Licenses at LicensiX

With Windows Server 2025 CALs (Client Access Licenses), you regulate lawful access to a Windows Server 2025. In this category, we offer suitable User CALs and Device CALs for businesses, organizations, and professional IT environments.

Whether you operate a classic Windows Server, a virtualized infrastructure, or hybrid scenarios: without the appropriate CALs, access by users or devices is not license-compliant.

What are Windows Server 2025 CALs?

A Client Access License (CAL) is an access license required whenever a user or device accesses services of a Windows Server 2025 —for example, file and print services, Active Directory, or server-based applications.

Important: CALs do not replace the server license itself but complement it. A complete licensing setup always consists of a Windows Server 2025 license and the corresponding number of CALs.

User CAL 2025 or Device CAL 2025 – which is better?

With Windows Server 2025, you can choose between User CALs and Device CALs. Both licensing models meet different requirements and can be flexibly combined.

Advantages of Windows Server 2025 CALs

With the right Windows Server 2025 CALs, you ensure that your server environment is not only technically stable but also fully compliant from a licensing perspective.

• License-compliant access to Windows Server 2025
• Flexible use as User CAL or Device CAL 2025
• Suitable for physical, virtual, and hybrid server environments
• Scalable as the number of users or devices grows
• Investment security for long-term IT planning

Optimally combined with Microsoft licenses

In practice, Windows Server 2025 CALs are often used together with other Microsoft solutions—such as Microsoft 365, classic Office licenses, or additional Windows Server editions.

This allows you to build a powerful, centrally managed IT infrastructure for file storage, user management, security, and productive work.
