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.

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."
"The initial insights are spot-on, clear, and deliver immediate value right out of the box."
"The resource-level cost view is one of the most valuable features for us, providing clear visibility into where our costs are coming from and making it easier to investigate spending in detail."
 

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."
"There should be better ways to ignore recommendations or filter recommendations."
