OPSWAT NetWall Optical Diode

Hardware enforced one-way transfer for IT and OT environments

NetWall Optical Diode provides a reliable transfer of data over a hardware enforced one-way communications link, enabling secure data transfer between isolated networks. To support the concurrent transfer of multiple data types, NetWall Optical Diode ensures the security and integrity of your critical assets.

NetWall Optical Diode Delivers:

Reliable, unidirectional data communications

  • Hardware enforced air-gapped security for critical assets
  • Prevents malicious C&C communications from the OT network
  • Segments and protects networks, devices, historians, SCADA, DCS, HMIs, and PLCs

Seamless integration with OPSWAT MetaDefender Kiosk and Vault

  • Secure transfer of software updates and other files to the protected domain

Reliable Payload Delivery

Redundant Optical Connection

Data integrity checks over redundant optical links achieve unsurpassed reliability

Advanced tuning features

Allows NetWall Optical Diode to be optimized for your transfer needs

No Return Path

A non-networked serial connection between the NetWall USG server pair enforces one-way data flows.

Scalable Industrial Cybersecurity

OPSWAT NetWall Optical Diode comprises two 1U or din rail mount appliances with
a non-networked optical connection between them.

Easy to Deploy

Preconfigured platform deploys quickly and seamlessly.

Highly Scalable

Choose 100Mbit, 1Gbit, or throughput for 1U server configuration — all software is selectable to meet current and future requirements. The din rail version can be configured for 10Mbps or 100Mbps throughput.

Full Support for Industrial Protocols

Includes OPC DA, A&E, and UA, plus Modbus/TCP, file transfers, and TCP/UDP sockets.

Transparent to Users

Fast and high-fidelity data replication means there is no need to alter work procedures of corporate users.

Enables Regulatory Compliance

Supports compliance with Industrial Cybersecurity standards:

  • NERC CIP
  • NIST CSF, ICS, 800-82,
    800-53
  • IEC 62443
  • NRC 5.71
  • CFATS
  • ISO 27001, 27032, 27103
  • ANSSI
  • IIC SF
  • and more

Protects against Industrial attack techniques outlined by MITRE ATT&CK for ICS.
