Thank you for considering ShiftLeft. I am the author of ShiftLeft Scan, a free open-source tool, which I believe is better suited for your infra scanning use case.
Scan supports a range of languages and frameworks including infrastructure code such as ansible, terraform, kubernetes and so on. All scan tools and integrations are open-source and available on GitHub.

I will be more than happy to assist you with any investigation.
