Works at a tech vendor with 11-50 employees
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.

Bank projects have gained strong security and reliable performance for critical applications
From my experience as a partner, the biggest advantage of Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages is that it is a stable and reliable product. It is a reliable OS when I am using it for applications because we run middleware software upon the OS, which means if there are problems or security holes in the OS, my applications also face those issues. In that scenario, the stability and security of Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages is commendable. The security policy of Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages is improved, but security measures must still be implemented. After we install the operating system, the customer's bank security team will harden the OS to block any potential breaches or malicious activities. To measure performance with Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages, I assess how much RAM and CPU the background processes are consuming. I can restrict these processes to ensure that minimal background processes run, allowing my application server software and applications to operate better with the available memory and CPU resources.

Quotes from Members

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

Pros

"Windows Server 2025 is a strong fit for enterprise environments heavily reliant on Microsoft technologies."
"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."
"It is pricey, but our product requires a high level of security and performance, making it much better than Ubuntu and other Linux options."
"From my experience as a partner, the biggest advantage of Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages is that it is a stable and reliable product."
"Cloud integration is quite easy, and containerization support along with file system level enhancements has improved considerably."
 

Cons

"Initial configuration complexity can still be high for teams without prior Windows Server expertise."
"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."
"Regarding the technical team of Red Hat, I find the support to be a mixed bag. In my region during office hours, calls go to the Asia Pacific support team, which is not up to the mark."
"There is room for improvement regarding response time and first-level support quality."
"Maybe for the virtual machine management, we utilize Red Hat Enterprise Linux 9 (redhat 9) | Support by SupportedImages because it is so powerful. We have a lower version of Red Hat for previous virtual machine management, and since we now have a new version, virtual machine management is more complicated."
