From first hearing about Sandstorm since the first open beta 10 years ago (https://news.ycombinator.com/item?id=10147774) and reading about it on/off since then, this is first time I hear anyone pitching it for "medical and other highly regulated industries". Where exactly does this come from?

Plenty of other similar self-hosted platforms, YunoHost is probably the closest, most mature and most feature-packed alternative to Sandstorm, at least as far as I know,.
