For PVWA/CPM/PSM servers, which operating system is necessary?

The correct choice of Windows 2019 as the necessary operating system for PVWA (Privileged Vault Web Access), CPM (Central Policy Manager), and PSM (Private Session Manager) servers is primarily due to its alignment with the latest security, performance, and support standards provided by CyberArk. Windows 2019 is a more modern operating system that offers enhancements in stability, security features, and compatibility with CyberArk’s evolving suite of tools compared to earlier versions.

Using Windows 2019 ensures that the software takes full advantage of the latest updates and security patches, which are critical in managing sensitive privileged accounts effectively. Additionally, as software continues to evolve, many vendors, including CyberArk, tend to align their applications with currently supported operating systems to ensure optimal functionality and support from the operating system vendor.

Earlier versions like Windows 2012 and Windows 2016 may support some features of CyberArk products but may lack the robustness and additional features found in the latest Windows version. Windows XP is significantly outdated and lacks the necessary modern security measures and updates, making it unsuitable for applications that handle sensitive data and privileged account management. Therefore, Windows 2019 is the best fit for ensuring secure, efficient, and supported operation of CyberArk components.
