Architecture Model

Control logic centralized.
Data systems unchanged.

Bastilon operates as a control plane above your existing data estate, enforcing runtime policy decisions and capturing traceable evidence without requiring platform replacement or data centralization.

How Bastilon Fits Into Your Architecture

Bastilon connects to existing systems and applies consistent governance across access, security decisions, and data movement throughout the environment.

Bastilon conceptual architecture overview
Bastilon sits between users and data systems, applying governance, security, and visibility without disrupting existing platforms.

Works with Existing Data Platforms

Deploy alongside relational databases, data warehouses, SaaS platforms, APIs, and modern data services without requiring system replacement.

Flexible Deployment

Run on-prem, in cloud environments, hybrid infrastructure, or fully air-gapped networks with a lightweight container footprint.

Control Flow at Runtime

  • Identity and policy context are evaluated on each query or movement action.
  • Tag-driven rules enforce masking, transformations, and row-level controls.
  • Decisions are logged automatically for traceability and audit evidence.
  • Governance context travels with the data during ingestion, migration, and sharing.

Architecture Outcome

By separating governance logic from operational data systems, Bastilon enables consistent controls, faster delivery, and reduced platform disruption.
