With ondeso SR, you have access to a reliable WSUS alternative on premise that is specifically designed for industrial environments. You retain full control over your OT systems without relying on cloud services.
Reliable management of
Windows updates in industrial settings
without cloud dependency
With ondeso SR, you have access to a reliable WSUS alternative on premise that is specifically designed for industrial environments. You retain full control over your OT systems without relying on cloud services.
A WSUS alternative on premise is becoming increasingly important for you if you operate industrial environments. WSUS has been used for Windows update management for many years. However, Microsoft has not actively developed the platform further since July 2024. Only security and compatibility updates are still provided.
At the same time, Microsoft is shifting its focus towards cloud based services such as Microsoft Intune or Azure Update Manager. This can work well in traditional IT environments. In your industrial network, however, cloud approaches often reach their limits.
Why cloud approaches are often not suitable for OT environments
Many production environments are intentionally isolated.
Typical requirements include:

Greater control, security, and transparency with an independent on-premises solution for OT systems running from Windows XP SP3
With ondeso SR, OT environments can be operated stably and independently entirely on-premises. They do not rely on cloud services or internet connections, thereby reducing external dependencies. At the same time, heterogeneous Windows environments can also be managed centrally.
Patch and software processes are controlled via clearly defined workflows. Updates can be tested according to a schedule and rolled out to production in a controlled manner. Manufacturer-specific update lists in accordance with IEC 62443-2-3 can also be taken into account.
Updates can be scheduled so that ongoing production processes are not interrupted. Even in highly critical OT environments, operations remain reliably secured, as ondeso SR was developed specifically for the requirements of industrial infrastructures.
