CEPHEUS PORTUS
Stop exporting.
Start governing.
Cepheus Portus lets regulated companies use their real source data in Power BI, Databricks, Snowflake, Microsoft Fabric and other cloud warehouses directly read-only, byte-exact, and with signed evidence their Quality team can verify without the manual export that breaks their audit trail.
WHY IT MATTERS
An uncontrolled copy is three problems at once.
Broken lineage
You can't prove the dashboard figure matches the source of record. The chain of custody an auditor asks for simply isn't there.
Re-validation burden
Every new export is a new artifact to control, document, and defend — repeated effort your Quality team can never fully retire.
Compliance exposure
Uncontrolled copies of GxP data are exactly what 21 CFR Part 11 and Annex 11 exist to prevent. Findings, not just friction.
ONE CONNECTOR, FIVE SOURCES
Not just SAS.
If your validated data lives in any of these, Cepheus Portus reads it into Power BI the same governed way — no source system required.
SAS
SAS datasets
.sas7bdat and .xpt transport (V5/6, V8/9)
DB2
DB2 exports
PC/IXF, the machine-independent export format
EBCDIC
Mainframe
EBCDIC data described by a COBOL copybook
TD
Teradata
FastExport / TDCH binary extracts
Same reader core. Every format lands in one exact model, so Power BI, Databricks, Snowflake, Microsoft Fabric and your warehouse all get each source with the identical fidelity guarantee and the same validation evidence.
FIDELITY YOU CAN PROVE
Every load is signed.
Anyone can verify it —
without us.
Exact by construction
DECIMAL stays exact decimal, integers keep their true width, timestamps to the microsecond, binary stays binary. Nothing is silently widened to a float.
Cryptographically sealed
Each conversion emits a signed manifest: the source hash, the row-equivalence digest, and the output hash — signed with a key that chains to the Cepheus Root CA.
Independently verifiable
A dependency-free reference verifier and its published specification ship alongside — your auditor confirms the seal with openssl, not our word.
HOW IT FITS
One governed reader. Five ways to consume it.
Cepheus Reader Core
SAS • DB2 • Mainframe • Teradata → One Exact Model
Signed ODBC connector — analysts read source files live in Desktop and scheduled refresh.
A Spark data source that reads in-lakehouse and lands a Delta table — no copy-out.
Cloud data platform storing and managing data with high performance, scalability, and secure sharing.
All-in-one platform bringing together data integration, engineering, and Power BI in a unified experience.
A container that converts to Parquet for BigQuery and Redshift, with a signed manifest.
THE PILOT
Prove it on your own files.
You choose the files
Three to five of your own representative source files — SAS, DB2, mainframe or Teradata, whatever you actually use. They stay in your environment.
Analysts see them live
Install the signed connector, open Power BI, and read them directly — connecting takes minutes, not a project.
Quality reviews evidence
The complete validation dossier and the signed IQ record are already in the box, ready for CSV review at their own pace.
Success is simple: your data reads correctly, and Quality is satisfied. Then we scope the rollout.
