Data Sovereignty
Tessera Sovereign is built on the principle that government data belongs to the government. All data is fully portable and available for export in standard, machine-readable formats at any time. There is no vendor lock-in, no proprietary data formats, and no barriers to migration. Upon contract conclusion, every record is returned in full. The government retains ownership of all data at all times, without exception.
