Minimize Risk - Maximize Control
Email, calendar, and contact data often include confidential and regulated information. But when mobile users or external systems need access, Exchange is typically exposed to the internet—or proxied through risky third-party solutions. This creates serious vulnerabilities.
CB Super Secure Exchange Server Sync solves this by eliminating direct access. It allows content to be synchronized across networks without opening your Exchange ports or creating any external attack surface. Data leaves your environment only through validated, filtered, and secured pathways—ensuring your compliance with regulations like GDPR, HIPAA, ISO 27001, and internal security policies.
Secure External Access for Sensitive Environments
CB Super Secure Exchange Server Sync is purpose-built for environments where exposing internal Exchange infrastructure is non-negotiable. It enables secure synchronization of sensitive mailbox content—emails, calendar entries, contacts, tasks—between internal and external systems without opening ports, exposing Exchange Web Services, or compromising your security perimeter.
Executive Mobile Access
Data‑Diode & Relay Integration
Cross-Network Synchronization
Audit-Ready Compliance
Built to Keep Exchange Behind the Firewall
CB Super Secure Exchange Sync isolates internal Exchange servers from external systems through a dual-instance relay architecture.
The solution can be deployed across two separate networks (e.g., DMZ and intranet, or air-gapped environments), with one-way synchronization and optional integration with data diodes.
The relay receives validated, filtered data from the internal Exchange via CB Exchange Server Sync, then safely delivers it to the external system. No inbound connections are required. No open Exchange services are exposed.
Security Without Compromise

Zero Exposure Architecture
Internal Exchange servers remain inaccessible to external systems—no open EWS, SMTP, or MAPI ports.
