 |No Public IP address required on the Azure VM| Azure Bastion opens the RDP/SSH connection to your Azure VM by using the private IP address on your VM. You don't need a public IP address on your virtual machine.|
 |No hassle of managing Network Security Groups (NSGs)| You don't need to apply any NSGs to the Azure Bastion subnet. Because Azure Bastion connects to your virtual machines over private IP, you can configure your NSGs to allow RDP/SSH from Azure Bastion only. This removes the hassle of managing NSGs each time you need to securely connect to your virtual machines. For more information about NSGs, see [Network Security Groups](../virtual-network/network-security-groups-overview.md#security-rules).|
