Automated hardening has standardized our servers and reduces effort for secure Windows workloads
The first-boot time is longer than a stock Windows AMI. Sysprep and the initial hardening pass add a noticeable delay before the instance is reachable, which is something to account for if you autoscale and need nodes ready quickly. The hardened defaults also occasionally trip up common installers and agents. A few of our deployment and monitoring tools assumed services or policies that the image had locked down, so we had to add exceptions. A short compatibility checklist of what the hardening changes from a default Windows install would have saved us that debugging. I would also like the option of a CIS Level 2 build for our more sensitive workloads since the image currently only ships a Level 1 baseline. Thanks.

Linux servers have supported secure deployments and provide straightforward configuration
We use a couple of third-party apps in Linux servers, such as Twingate or Fireflys, or we redirect our traffic on London-based servers. We use Linux and other third-party applications for security purposes. User interface is an area where Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages could improve. Mac is famous for its user interface and seamless experience with other products. Similarly, Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages should provide a better UI/UX experience over the OS and better connectivity and better application support. Windows and Mac support a vast variety of applications, but Linux is lacking in this area. System configuration is something I would see added to Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages in the future. The App Store lacks many applications, so it could improve the application support.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Because the image arrives CIS Level 1 hardened with the AWS tooling already in place, our servers come up patched, locked down, and ready to join the domain without a separate build out pass."
"Windows Server 2025 is a strong fit for enterprise environments heavily reliant on Microsoft technologies."
"You can download any open-source tools and run them on Ubuntu, which is also very helpful."
"I find Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages compatible with cloud services such as AWS."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages offers good security from the first minute of use and is better than Windows for me."
"When I think of the advantages of Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages, the very broad community support comes to my mind; most of the questions are very quickly and reliably answered, and that is in fact better than what we face with AlmaLinux, which is more of a niche type of operating system."
"The biggest advantage that I found in GitLab is that I have all the control of my code in house."
"Security features such as full disk encryption and firewall protection are, of course, important, in conjunction with server and storage."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages is a leader because it provides full architecture of servers, machines, and operating systems."
 

Cons

"The hardened defaults also occasionally trip up common installers and agents: a few of our deployment and monitoring tools assumed services or policies that the image had locked down, so we had to add exceptions."
"Initial configuration complexity can still be high for teams without prior Windows Server expertise."
"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages could be improved in two key areas: security and file management."

"Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages is not my main operating system."
"Working with text documents or the equivalent of MS Word, particularly .odt files, is a major challenge on Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages."
"I think we don't like Kernel Live Patches on Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages."
"Because of the community involvement, I mentioned that at some point I get stuck and need to rely on the community and either work out my own solutions."
"Emphasizing improvements for Ubuntu 20 (Ubuntu 20.04 LTS) | Support by SupportedImages, I note that it is a bit bloated right now; it could be more lean with supported packages."
