What AI says about Windows Network Policy Server

Network Policy Server (NPS) on Windows Server provides centralized authentication, authorization, and accounting for network access and lets you create organization-wide access policies for connections such as wireless, VPN, dial-up, and authenticating switches. As a RADIUS server, NPS authenticates and authorizes these connections and can log accounting data to local disks or SQL Server; as a RADIUS proxy, it forwards connection requests to remote RADIUS servers and can balance load across them. NPS is installed with the Network Policy and Access Services (NPAS) role and can be configured as either a RADIUS server, a RADIUS proxy, or both, with deployment options depending on Windows Server edition and installation type.
