The reason our customers haven’t required this is because we’ve tried to take security seriously from day one and Metaplane doesn’t store any customer data (just the metadata). We received our SOC2 Type II report, support IP whitelisting, SSH/Reverse SSH tunnels and are always exploring other integration options like AWS’ PrivateLink.
That said, we definitely understand the need to keep even metadata on-prem, so we plan on tackling that later next year.
