What is the benefit of using Azure VPN Gateway?

Using Azure VPN Gateway to establish secure connectivity is a fundamental advantage of this service. The Azure VPN Gateway allows you to create secure, encrypted tunnels between Azure virtual networks and on-premises networks or remote users. This is crucial for maintaining the confidentiality and integrity of data transmitted over the internet, protecting it from unauthorized access and ensuring that your communications remain private.

Furthermore, the use of Azure VPN Gateway supports various protocols, like IKEv2 and OpenVPN, which helps to facilitate secure connections according to industry standards. Implementing this gateway means that organizations can securely extend their on-premises networks to the cloud or enable secure access for remote employees, thus creating a more flexible and secure network architecture.

In this context, the other options do not adequately capture the primary function or benefit of the Azure VPN Gateway. While it might provide a public IP, it is not a free service, and providing a public IP does not define the core value of a VPN Gateway. The notion of enabling borderless deploying is also not specifically associated with the main purpose of VPN connectivity. Finally, suggesting that it reduces network speed contradicts the purpose of using such a secure connection, which is designed to facilitate reliable and secure data transmission rather than hinder performance.
