Let's hope so, I'd love to help teams take storage infrastructure management off of their plate! If you're in the public sector and interested in trying out Regatta, please shoot me an email at hleath [at] regattastorage.com.
The public sector is typically air-gapped, so not really.
I think it depends which part of the public sector! AWS GovCloud is not airgapped, but I certainly know of deployments which are.
