OPSWAT NetWall USG

Unidirectional Security Gateway for IT and OT

netwall-usg-specs-10gbit-sec

NetWall USG provides access to real-time OT data and enables secure data transfer to the OT environment without compromising the security and integrity of your critical production systems.

As the frequency of OT/IT network communications increases, so to does the number of vulnerabilities. Cyberattacks, malicious command and control communications, and other threats leave historians, SCADA, DCS, HMIs, PLCs, and other devices on your critical network susceptible without reliable gateway security. Additional security is required when select applications require data replies.

MetaDefender Unidirectional Security Gateway (USG) assures uncompromising security for OT/IT communications, enabling secure IT-OT data and file transfers without the risk of introducing security threats to critical OT production networks and assets.

MetaDefender Unidirectional Security Gateway (USG) enforces one way data flows while guaranteeing payload delivery and preventing data loss, avoiding the need for data retransmission.
