Data exits the approved boundary
Hosted services place files, metadata, or logs in infrastructure the program does not operate.
Use case / Self-Hosted
Your boundary. Your infrastructure. The same policy plane.
Run Stellarbridge where your requirements demand—inside your network, on infrastructure you operate, with files and logs under your control.

The operating reality
When the security boundary is contractual, outsourced infrastructure can become the exception your program cannot accept.
The control plane becomes a black box
Teams cannot inspect the architecture behind the evidence they are expected to defend.
Operational ownership stays ambiguous
Program obligations do not disappear because a SaaS vendor owns the runtime.
What changes with Stellarbridge
Govern the workflow, not just the destination.
01 / 03
Boundary
Deploy where the data is allowed to live.
Place storage, policy enforcement, and event records inside the network and residency boundary your organization owns.
- No external file routing
- Logs retained on your systems
- Architecture aligned to segmentation
02 / 03
Parity
Keep the full governance model.
Self-hosted is the same policy-first product, not a reduced offline edition. The enforcement and evidence model stays intact.
- File-level access policy
- Governed external exchange
- Human and agent identity controls
03 / 03
Ownership
Stand behind the architecture you run.
Review deployment diagrams, system boundaries, integration points, and operating responsibilities before production.
- Architecture documentation
- Structured security review
- Deployment engineering support
Control plane
The evidence is part of the action.
Every request resolves to an attributable identity, an explicit policy decision, and a durable record.
01Runtime
Application services execute inside your approved environment.
02Storage
Files remain on infrastructure and in regions you select.
03Evidence
Audit history stays within your logging and retention boundary.
04Operations
Ownership and support responsibilities are made explicit.

Direct answers.
01Is self-hosted a reduced version of Stellarbridge?
No. It uses the same policy and governance model as the managed offering, deployed inside infrastructure you control.
02What infrastructure do we need?
Requirements depend on scale and integration needs. We review architecture, sizing, storage, networking, and operational ownership during deployment planning.
03Can our security team inspect the architecture first?
Yes. Architecture documentation, deployment diagrams, and a security review are available before commitment under the appropriate confidentiality terms.
