Microsoft Windows Server 2025 - 1 User CAL CSP

Secure, Flexible Access for Individual Users

Microsoft Windows Server 2025 – 1 User Client Access License (CAL) (CSP) provides a single named user with the rights to securely access a Windows Server 2025 environment. Designed for organizations using the Server + CAL licensing model, this user-based license enables consistent access to server resources across multiple devices under one user identity.

Delivered through CSP licensing, it offers simplified procurement, flexible scaling, and streamlined license management for modern IT environments.

Enable Access by User, Not Device

One License Per Named User

This User CAL is assigned to a specific individual, allowing them to access Windows Server from any supported device. Whether working from a desktop, laptop, or mobile device, the user maintains seamless access without requiring additional licenses per endpoint.

Ideal for Multi-Device Workforces

Perfect for employees who regularly switch between devices, User CALs simplify licensing by focusing on the user rather than the hardware—reducing complexity for IT teams.

Built for Windows Server Environments

Works with Windows Server 2025

This license is required to access Microsoft Windows Server 2025 (server license sold separately). Once assigned, users can connect to server-hosted services such as applications, file storage, Active Directory, and internal business systems.

Seamless Integration with Business Tools

Maintain Security and Compliance

Identity-Based Access Control
