2. [Chef Inspec](https://community.chef.io/tools/chef-inspec)(Apacha 2.0 and proprietary): Infrastructure-as-Code to auto-configure VMs and apps running in it to meet compliance.
The binary installation(the one you get when you follow installation
instructions) requires accepting EULA, so essentially proprietary? Please see [here](https://github.com/inspec/inspec/issues/5109) for
the issue discussing the EULA and [here](https://saf.mitre.org/#/faq#5) for building Apache 2.0
compliant binary.
Also, there's the [CINC is not CHef (CINC)](https://cinc.sh/)
project that distributes fully FOSS([Apache2.0 and free of EULAs](https://cinc.sh/goals/)) Chef software.
