SBE FUSION™/CROSS-DOMAIN DIGITAL THREAD

One Digital Thread, across every boundary.

A cross-domain capability for the Digital Thread. Share data across organizations and classification levels, live or air-gapped, without losing traceability.

Built on the Same Rules

SBE Fusion™ uses the same publish, subscribe, and mapping mechanisms as SBE’s standard tool adapters. Cross-organization data follows the same configuration management and provenance rules as everything else in your Digital Thread.

Typical Use Cases

Where SBE Fusion™ keeps programs connected.

OFFLINE

Cross-classification collaboration

Two SBE Platform instances at different classification levels share Digital Thread data via signed file transfer over a data diode or removable media.

ONLINE

Multi-organization programs

Two organizations on a shared program, such as a prime and a supplier, keep a live, governed connection so each side’s updates are reflected in the other’s environment.

OFFLINE

Enterprise system migration across air-gapped networks

Two air-gapped environments, each with its own enterprise system and SBE Platform instance, stay synchronized: data is normalized on one side, exported, security-scanned, then imported, reviewed, and refreshed on the other.

Two Modes of Operation

Connect live, or don’t connect at all.

Choose the approach that matches your network and security requirements.

Online Fusion

LIVE CONNECTION

A direct connection between two SBE Platform instances, authenticated and encrypted over TLS. It opens only when a publish, refresh, or diff is invoked.

Online PublishBIDIRECTIONAL
Two companies or units share information both ways. Each side keeps its own mappings and chooses which external items to include or ignore.
Online RefreshONE-WAY · OUTBOUND
Information flows in one direction only. The destination stays current on what has been refreshed.

Offline Fusion

AIR-GAPPED

No network connection at all. Built for environments that cannot connect directly, most often because they sit at different classification levels.

01Package and sign. Data, manifest, signature, and public key in one signed file.
02Transfer. Through a data diode or approved portable media.
03Verify and scan. Signature, checksum, and malicious content checked before ingest.
04Publish and diff. Changes are reviewed against existing data before they apply.
05Track origin. Metadata preserves the source tool and environment.
Diff and Merge Controls

Data owners decide what lands.

Only designated data owners on the high side review and merge changes from the low side. Everyone else simply refreshes and gets the latest approved data.

Key Features

Built for controlled collaboration across any boundary.

01

Bi-Directional or One-Way

Supports mutual, two-way collaboration and controlled, one-way sharing where only one side should push updates.

02

Cross-Domain Ready

Offline mode enables Digital Thread continuity across air-gapped or classification-separated networks without a network bridge.

03

Data Integrity Verification

Offline packages are cryptographically signed and verifiable, and support diff comparisons before changes are applied.

04

Standard, Secure Transport

Online communication runs over authenticated, encrypted TLS channels using REST and gRPC, consistent with platform-wide identity and access management.

05

Provenance Preserved End-to-End

Origin metadata travels with each data artifact, so the source tool and environment stay identifiable across multiple hops.

06

Diff and Merge Controls

Data owners review exactly what is changing and merge only what is needed, rather than a blind overwrite.

Security and Access

No separate security model to manage.

SBE Fusion™ inherits the SBE Platform’s existing identity, authentication, and access control framework, so the roles you already configured govern cross-boundary data too.

Security & Scalability →
ONLINE

Authenticated, encrypted, authorized

REST and gRPC connections authenticate through the platform’s identity provider, all traffic runs over TLS, and the same role-based authorization applies across the platform.

OFFLINE

Verifiable, scanned transfers

Packages are signed at creation, verified on receipt, and checked for malicious content and checksum integrity before they are considered safe to ingest into a higher-security environment.

Extend your Digital Thread past the network edge.

Two companies collaborating in real time, or two networks sharing verified data on a schedule. SBE Fusion™ keeps traceability and control intact either way.
