MetaDefender Bilateral Security Gateway

Secure OT/IT Communication for Data Replication

MetaDefender Bilateral Security Gateway helps organizations replicate and transfer historian and SQL database data from OT to IT without weakening the security of critical production systems. It enforces one-way data flow while supporting a proprietary mechanism for selected application replies. As a result, teams can keep essential data moving without changing application settings or user workflows.

This solution is especially useful in industrial environments that require both strong isolation and reliable data replication. The datasheet explains that the platform supports secure response handling while preserving full protocol break and physical isolation.

What Is MetaDefender Bilateral Security Gateway?

MetaDefender Bilateral Security Gateway is an OT security platform built for secure replication of historians and relational databases. It allows required replies for select applications while still enforcing one-way communication, physical isolation, and protocol separation.

Because of this design, the platform supports reliable OT-to-IT data communications with no data loss and no database synchronization issues. It also helps isolate OT and ICS assets against cyberattacks.

Key Features of MetaDefender Bilateral Security Gateway

This platform combines secure communication with practical support for industrial replication workflows.

• Guaranteed payload delivery with no data loss
• Anti-overrun control to reduce overflow, retransmissions, and sync issues
• One-way data flow enforced by a non-networked serial connection
• Bilateral support for select application replies with full protocol break and physical isolation
• Fast deployment with a preconfigured platform
• Simple operation after one-time setup
• Scalable performance from 100 Mbps to 1 Gbps, with a 10 Gbps option on enterprise servers

Benefits for OT Data Replication

MetaDefender Bilateral Security Gateway is designed for environments that need secure OT-to-IT replication without compromising security boundaries. It supports lossless communications, reliable database replication, and response-aware workflows for select applications. Moreover, it helps protect networks, devices, historians, SCADA, DCS, HMIs, and PLCs.

Because of these capabilities, the solution is a strong fit for industrial operators that need secure historian replication and database connectivity while maintaining OT isolation.
