OK. Specific Sentinel integration might be optional (or not even possible), not too sure. But the only way we'd be compliant with the Sentinel policies is if I can use the pre-designed modules in TFE.
Terraform modules are within our roadmap, for now we have the market-place where you can design template architectures that contain your own rules and policies that you can distribute within your organization or team(s), you can make them public if you want as well.
