Governance & Sovereignty

Catalogs, lineage & on-soil residency.

Data sovereignty isn't a checkbox. We build the catalog, lineage, access policy and on-soil deployment topology that passes audit without blocking engineering velocity.

What we ship

Capabilities

Data catalogs, lineage, access control and sovereign deployments that meet EAC and national data-protection requirements without slowing teams down.

  • 01

    Catalogs (DataHub / Unity / OpenMetadata)

    Every dataset, column and transformation catalogued with business descriptions, owners and SLAs — searchable by anyone, governed by policy.

  • 02

    Column-level lineage & access policy

    End-to-end lineage from raw source to dashboard column — with attribute-based access control that enforces PII masking automatically.

  • 03

    On-soil & on-prem deployments

    Full-stack deployments inside Tanzanian, Kenyan and Ugandan data centres for regulated workloads — no data crosses borders.

  • 04

    PDPA / GDPR-aligned audit trails

    Immutable access logs, consent tracking and data-retention automation aligned to EAC personal data protection frameworks.

Outcomes

  • Audit-ready data governance posture
  • Column-level access control that teams respect
  • On-soil deployments for regulated workloads

In the field

  • 1

    Central bank data compliance

    Full catalog, lineage and access control for 40TB of payment data — audit evidence produced in under a day.

  • 2

    Health data sovereignty

    Patient data kept on-soil in Tanzania — cross-border federated learning without any PII leaving the country.

  • 3

    Insurance group data mesh

    5 subsidiary data domains governed independently but discoverable centrally — data product SLAs enforced automatically.

How we deliver

Our delivery process

Every engagement follows the same rigorous four-stage approach — so you know exactly what to expect, and when.

  1. Step01

    Data asset inventory

    Automated crawlers discover every table, topic and file — tagged with domain, classification and sensitivity level.

  2. Step02

    Lineage mapping

    Column-level lineage traced from every source system through every transformation to every downstream consumer.

  3. Step03

    Policy & access control

    OPA policies enforce masking, access and retention rules — reviewed by your legal and compliance team before deployment.

  4. Step04

    Sovereign deployment

    Infrastructure-as-code Terraform modules for on-soil deployments — auditable, repeatable, and jurisdiction-specific.
