Secure Data Integration for Mission-critical Systems

Enable controlled, bidirectional data transfer across air-gapped networks with Connect Bridge and data diode technology

Secure, Scalable Integration for Complex Environments

Connect Bridge is a middleware solution that can connect nearly every software. You just need to select the connectors you want, for example, Microsoft Exchange Server, Microsoft SharePoint, or a specific type of database, just to mention a few among the 400+ connectors.

Connect Bridge for Air-Gapped Networks facilitates data integration in physically segmented environments using data diodes for maximum security. It allows organizations to streamline secure data transfer between different applications in stand-alone networks, even bidirectionally and without exposing sensitive data to cyber risks.

Connect Bridge and some of its connectors

Connect Bridge has out-of-the-box support for enterprise platforms like Microsoft SharePoint, Dynamics, Exchange, and other enterprise server software.

No out-of-the-box connector available for the enterprise software you want?

Not a problem! Our team can quickly build any connector you need. It is also possible for you to develop it yourself using our SDK.

Want to connect to a cloud solution?

This is possible! Connect Bridge also enables secure cloud-to-on-premises connections. These can be useful for your Business Continuity Plan (BCP) or for backup purposes.

Whatever connectors are used, Connect Bridge for Air-Gapped Networks ensures seamless, policy-controlled integration while maintaining compliance with the strictest security standards—critical for organizations handling sensitive or even classified information.

Why Choose Connect Bridge for Air-Gapped Networks?

Ensure secure, efficient, and controlled data integration without compromising network segmentation.

Secure and Efficient Data Transfer

Zero connectivity networks—often used in critical industries such as defense, intelligence, and finance—require robust solutions for extracting, integrating, and transferring data without exposing sensitive systems to cyber threats.

The combination of Connect Bridge with data diodes ensures bidirectional communication to improve productivity, while enforcing strict access controls and security policies in such compartmentalized networks.

Eliminate Manual Extraction Risks

Manually transferring data between segmented networks using USB drives or other physical methods introduces serious security risks, and potential compliance violations.

Connect Bridge addresses these threats by establishing a secure, policy-driven process. This minimizes human error, reduces insider threats, and ensures that only authorized and filtered data can move between isolated environments.

Trusted by High-Security Industries

Organizations operating in sectors with the highest security requirements—such as defense, healthcare, financial services, and government agencies—trust Connect Bridge to integrate their critical systems without creating security vulnerabilities.

By leveraging data diode technology and strict user access controls, Connect Bridge enables secure data movement while ensuring that stand-alone networks remain fully protected from cyber threats.

Why Choose Connect Bridge for Air-Gapped Networks?

Precisely control data flow between high-security and low-security zones with comprehensive filtering capabilities.

Filtering can be applied to all data synchronizations, allowing organizations to manage data transfer based on classification levels, keywords, and other criteria.

Out-of-the-box filtering is available for Exchange Server integrations, while for other systems, custom filtering can be developed to meet specific requirements.

This flexibility ensures maximum security and control, allowing organizations to either use ready-made filters or implement tailored solutions as needed.

Applications

Military & Defense
Synchronize military intelligence and operational data between field-deployed networks and headquarters without exposing mission-critical systems.
Government Agencies
Enable controlled file transfers between classified and unclassified networks without exposure to data leakage or cyber infiltration.
Healthcare Data Exchange
Ensure HIPAA-compliant data exchange between clinical systems preventing cyber threats against patient records.

SCADA & Critical Infrastructure Protection
Integrate industrial control systems with corporate IT networks while preventing cyber-physical attacks and meeting compliance standards (NERC CIP, IEC 62443).
Exchange of Legal & Financial Data
Ensure precise control over sensitive data exchanged between separated corporate divisions, preventing unauthorized access.
Research & Development (R&D)
Transfer R&D data between isolated research labs and corporate networks, preventing intellectual property theft and cyber-espionage.

Technical Overview

Deployment

Connect Bridge for Air-Gapped Networks is a flexible solution and can be deployed either directly onto your infrastructure or pre-installed on ST Engineering Data Diodes, offering a fast and hassle-free deployment option.

Access Control

Advanced access controls allow fine-grained control over what data and which users have access beyond the isolated zone. This feature helps ensure sensitive information stays within its intended environment while meeting operational requirements.

Compatibility

Connect Bridge for Air-Gapped Networks has an out-of-the-box connector for each system it is compatible with, plus you can build your own connector, if needed.

In terms of hardware, Connect Bridge for Air-Gapped Networks was built to work in tandem with ST Engineering Data Diodes, ensuring secure one-way or filtered two-way communications. For other types of data diodes, please contact us.

frequently asked questions

Connect Bridge ensures secure bidirectional data transfer in air-gapped environments by leveraging data diodes set up in a specific way. This setup guarantees that data is transmitted securely between networks without creating a direct bidirectional connection that could be exploited. While the physical layer remains strictly controlled, Connect Bridge enables policy-driven, controlled data exchange, ensuring that only authorized and filtered information moves between high-security and lower-security zones.

Connect Bridge gives you the flexibility to integrate with virtually any system. You simply need a connector for that system. Whether you use one of our 400+ out-of-the-box connectors, a custom connector built specifically for your environment, or prefer to develop it yourself using our SDK, we offer a solution that fits your needs.

Our team can rapidly develop custom connectors for specific applications or meet unique requirements. Alternatively, your developers can leverage our SDK to build their own connectors with ease.

In addition to custom integrations, Connect Bridge also supports a wide range of major business systems out of the box, including:

Microsoft SharePoint (document management and collaboration)
Microsoft Dynamics (ERP & CRM solutions)
Microsoft Exchange (all mailbox items - calendar, tasks, contacts and email)
Manufacturing Execution Systems (MES), SCADA & Industrial Control Systems (ICS)
Database Management Systems (SQL Server, Oracle)

Yes. Connect Bridge is fully customizable to align with your organization's security policies, compliance requirements, and operational workflows.

As you develop your own solution, you can establish custom filtering rules to prevent restricted or sensitive data from crossing security boundaries. Whether you need to enforce strict regulatory compliance, implement specific data transfer controls, or meet the unique needs of your industry, Connect Bridge can be adapted to fit your security and operational frameworks.

Data diodes are hardware-enforced security devices that allow data to flow in only one direction, ensuring that information from a high-security network can be transmitted outward without creating a path for inbound connections. This eliminates the risk of cyber threats infiltrating critical systems while allowing controlled data exchange. In the Connect Bridge framework, data diodes serve as the foundation for secure bidirectional workflows, transferring information in a structured and policy-controlled manner without compromising network isolation and cybersecurity.
