Supplier access expands silently
Shared folders and inherited permissions give partners more visibility than the work requires.
Use case / Manufacturing
Data governance for manufacturing.
Store and share large CAD files, and other highly sensitive information and IP related to manufacturing both internally and with partners regardless of whether or not they have Stellarbridge.

The operating reality
One uncontrolled technical file can expose IP, break a contract, and put the entire program under review.
Revisions escape the record
Downloads and email handoffs separate technical data from its authoritative version and history.
Audit evidence arrives late
Teams reconstruct who sent what only after a program office or customer asks.
What changes with Stellarbridge
Govern the workflow, not just the destination.
01 / 03
Exchange
Give every supplier a governed path.
Replace broad portals and attachment chains with identity-aware exchange scoped to the program, package, and permitted action.
- Time-bound partner access
- No consumer file-share detours
- Upload and download events attributed
02 / 03
Control
Keep the authoritative file under policy.
Storage and movement share the same policy plane, so the control model does not disappear when a file changes hands.
- File-level permissions
- External sharing gates
- Revision and metadata context preserved
03 / 03
Evidence
Answer the audit from the record.
Every consequential action produces evidence tied to actor, resource, decision, and time.
- Chain-of-custody reporting
- Tamper-evident event history
- Human and agent actions separated
Control plane
The evidence is part of the action.
Every request resolves to an attributable identity, an explicit policy decision, and a durable record.
01Identity
Employees, suppliers, and automation remain distinct actors.
02Scope
Authority narrows to named files, folders, programs, and actions.
03Decision
Allow, deny, or human approval resolves before movement.
04Record
Every result becomes durable program evidence.

Direct answers.
01Can suppliers exchange files without broad workspace access?
Yes. Partner access can be scoped to a specific exchange, file set, and permitted actions instead of granting visibility into a general collaboration space.
02Can Stellarbridge support CUI and CMMC-oriented workflows?
Stellarbridge provides the policy enforcement, identity, encryption, and audit capabilities needed for controlled data movement. Your organization remains responsible for its complete compliance program and boundary.
03Can this run inside our own environment?
Yes. Self-hosted deployment is available when residency, segmentation, or program requirements call for infrastructure under your control.
