Airport e-Gate Border Control

Case Study: Secure Watchlist Distribution for Border Control

Law Enforcement Agency in the Middle East (GCC)

Extremely high exposure risk due to Internet-facing destination systems

Full database replication of a MS SQL Server Enterprise environment

Requirement for continuous availability and consistency of watchlist data

Need for secure high-availability architecture

Need / Problem / Context

Securing Real-Time Watchlist Access at Airport Borders

A government law enforcement agency needed to securely distribute a sensitive national watchlist database to an external application used at airport border control checkpoints. This application, partially exposed to the Internet, required continuous access to up-to-date data to support real-time identity verification and threat detection.

The challenge was to enable seamless and reliable data availability at the operational edge, while ensuring that the classified source environment remained fully isolated and protected from any potential cyber intrusion or backflow risk.

Solution deployed

Cyberium implemented a resilient unidirectional replication architecture designed to ensure secure and continuous database distribution without exposing the source environment.
