Hi @Brian , I understand you're interested to use Microsoft Defender for Identity VPN integration.
Microsoft Defender for Identity can integrate with your VPN solution by listening to RADIUS accounting events forwarded to Defender for Identity sensors, such as the IP addresses and locations where connections originated. VPN accounting data can help your investigations by providing more information about user activity, such as the locations from where computers are connecting to the network, and an extra detection for abnormal VPN connections.
VPN Server address is your VPN server, there is no Microsoft Defender VPN server.
