Cepheus Engineering delivers smart, governed migration of legacy systems to the modern cloud: legacy analytical platforms and BI estates (SAS and more), legacy applications (PowerBuilder, VB6), and legacy data sources (SAS, mainframe, Teradata). Our flagship, Cepheus Portus, reads legacy data files directly in your own environment and issues a cryptographically signed attestation proving the migrated data matches the source, row for row, with no data egress. Built for regulated industries where migration must be provably faithful, not just complete.
