Featured Reviews

Aladin Steiner - PeerSpot reviewer
Has good scalability and provides secure access to the virtual machines
The product improved the security posture of our organization. We don’t have open ports and connect them to servers using it. We can carry out two-factor authentication to protect the devices with conditional access features. It would be nice to have a feature to copy and paste the files into servers. I rate the product a nine out of ten.

"The solution's most valuable feature is that it is easy to use...It is modernized, so I can create complex infrastructures."
"The most significant advantage lies in its runbook features, particularly beneficial for our infrastructure team."
"Azure Bastion is preferable because you just switch it on and off you go."
"Azure Bastion makes it easy to provide quick virtual machine access to our customers."

More Azure Bastion pros
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
 

Cons

"We are not able to copy and paste files directly into the server over the patch host. We have to transfer files over to Azure Storage."
"While general support is valuable, having a detailed breakdown of the specific issues would contribute to a more streamlined and efficient resolution process."
"Speaking of AI, having Microsoft Copilot in Azure Bastion would be good."
"There are some challenges because Bastion is more compatible with Edge but not with the other browsers. As an organization, it doesn't make sense that we have to use only Edge. We should be able to access Bastion over Chrome, Mozilla, or Opera. It should be our choice."
"There is room for improvement with AI features. I would like to see integrated AI features with Azure Bastion, especially for connectivity issues."
"The protocol speed could be faster."
"When you have a boot issue on Windows, you cannot use Azure Bastion to fix it. You have to use the Azure console or the VM console, and it is very limited."
"You are charged for retrieving your own data."
More Azure Bastion cons
"The integration is not as seamless compared to competitors like Palo Alto."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
 

Pricing and Cost Advice

"The tool is cheaply priced. I would say that the product is free to use."
"Azure Bastion's pricing is good."
"The pricing is a lower decision point than high-quality security for our organization. Better security comes at a cost, but it's worth it, and that's what we tell our customers."
"It does not save money for us."

Overview

Azure Bastion is a service you deploy that lets you connect to a virtual machine using your browser and the Azure portal. The Azure Bastion service is a fully platform-managed PaaS service that you provision inside your virtual network. It provides secure and seamless RDP/SSH connectivity to your virtual machines directly from the Azure portal over TLS. When you connect via Azure Bastion, your virtual machines do not need a public IP address, agent, or special client software.

Microsoft

In this era of hybrid work, shadow IT creates an increasingly serious security risk. Microsoft Defender External Attack Surface Management helps cloud security teams see unknown and unmanaged resources outside the firewall.
