Description

Enable only 'Azure Active Directory' (Microsoft Entra ID) authentication for Azure VPN Gateway point-to-site connections.

Rationale

Microsoft Entra ID authentication provides strong security and centralized identity management, and reduces risks associated with static credentials and certificate management.

Impact

Azure VPN Gateways incur hourly charges, with additional costs for point-to-site connections and data transfer. Pricing varies by SKU and usage. Refer to https://azure.microsoft.com/en-us/pricing/details/vpn-gateway/ for details.
