What service provides secure and seamless RDP and SSH access to virtual machines without public IPs?

Azure Bastion provides secure and seamless Remote Desktop Protocol (RDP) and Secure Shell (SSH) access to virtual machines without the need for public IP addresses. This service acts as a fully managed platform that allows you to access your VMs directly through the Azure portal over SSL, eliminating the need to expose your VMs to the public internet. It ensures that secure connectivity is established, thereby reducing the attack surface and enhancing the security posture of your Azure environment.

Azure Bastion integrates with existing virtual network infrastructure, providing access to VMs simply by connecting through a web browser. This means the communication is secured, managed, and operated directly within Azure’s ecosystem, making it significantly easier for administrators to manage access without worrying about maintaining IP whitelisting or VPN configurations.

In contrast, other services such as Azure Firewall or Conditional Access focus on different aspects of network security and access management, like filtering traffic and enforcing policies, respectively. Just-in-time (JIT) VM access, although it is a useful security feature that allows you to limit the duration of access to VMs, does not inherently provide a way to connect securely without public IPs. Azure Bastion, therefore, is the correct choice for enabling secure, seamless access to virtual machines in a
