We are using SaltStack SecOps for a rather large fleet of VMs that include a mixture of both Linux and Windows, with many different OS versions for each. It is used to view the compliance of the systems within our infrastructure.
This product brings all of the rich data that it collects under once central view. It makes the remediation of compliance or security issues quick and easy to understand. Being able to see this data allows us to be agile and we are able to make changes on a massive scale, thus reducing the manpower needed to implement changes.
