Bidirectional Email Synchronization for
Air-gapped Networks
Enable secure, policy-driven exchange server synchronization while keeping your data safe with CB Exchange Server Secure Sync with Data Diodes
What is
CB Exchange Server Secure Sync with Data Diodes?
Traditionally, Microsoft Exchange has been seen as a security risk for organizations operating in highly secured environments like the military, government, and finance sectors.
These organizations were often faced with a difficult choice: prioritize security at the cost of productivity or increase collaboration with unacceptable risks.
CB Exchange Server Secure Sync with Data Diodes introduces an industry-first solution to this challenge.
Designed for highly isolated environments, the software leverages data diodes—hardware-enforced tools for one-way communication—to enable secure, policy-driven bidirectional synchronization of calendars and tasks between Exchange Servers.
The synchronization is done with complete control over what data flows out of the isolated environment, ensuring sensitive information remains uncompromised. This was previously unattainable in strictly segmented networks and is a game-changer.

KEY FEATURES
Secure Synchronization Across Zero Connectivity Networks
Enable seamless synchronization of emails, calendars, and tasks across Exchange Servers, even in classified or high-security networks, while maintaining full compliance with strict security protocols.
Filtering and Control Options
With CB Exchange Server Secure Sync with Data Diodes, you’re in control of what data flows in and out of your environment. Tailor synchronization policies to match your organization’s operational and security needs, ensuring only authorized data can leave the secured zone.
For example, you can:
- Apply inclusion or exclusion filters: Define the data allowed for synchronization based on specific keywords, domains, email addresses, or other criteria to ensure only non-sensitive information leaves the network.
- Secure calendar items: Automatically redact confidential information by removing attachments, meeting participants, or event subjects, or by appending markers to indicate the source server.
These advanced filtering capabilities are optional yet powerful tools to meet unique security requirements, ensuring you maintain full control and that your internal data remains secure.

frequently asked questions
In the context of this solution, data diodes act as a secure gateway between the isolated network and external systems, enabling controlled bidirectional synchronization of emails, calendars, and tasks while upholding strict security requirements. They enforce a unidirectional communication path, ensuring that sensitive or classified data within the high-security network is never exposed to unauthorized access.
