Bayshore Networks Announces New NetWall USG™

High Performance Industrial Airgap Bridge Secures Outbound Plant Data Transfer

Durham, NC – June 1, 2020, Bayshore Networks, the leading provider of active cybersecurity solutions to protect the safety and integrity of industrial and critical infrastructure networks, has announced the release of NetWall USG™, a new, affordable, hardware device that provides safe, non-routable one-way (unidirectional) data transfer from trusted sources in the plant to untrusted outside destinations.

NetWall USG physically separates, secures and isolates sensitive equipment in the trusted plant zone from risk of internet exposure or malicious activity via data diode functionality – essentially providing an airgap bridge. This allows plants to safely transfer files, replicate servers, integrate plant data into IT tools such as SIEMS, and feed business data analytics to outside business destinations without risk of compromising sensitive equipment or plant operations.

Data diodes, also frequently called “unidirectional” gateways, are one of the strongest security controls available to companies who want to transfer data from trusted to untrusted domains because they use hardware to enforce one-way communications, isolating the trusted network from any form of inbound connections. For years they have been used to protect and isolate government organizations who need to exchange data but have differing security clearance levels, and also for large, regulated industries such as nuclear power plants and others.

“Everybody wants to get data directly and securely from the plant floor to corporate business destinations for tasks like replication, analytics, security threat hunting and decision support. Until NetWall USG, this has been complex and expensive for most organizations to do.
– Eric Byres, inventor of Tofino Security, and CEO of supply-chain security company aDolus.

However, data diodes are not without their challenges. These include high cost for the technology, relatively low bandwidth compared to typical networking technologies, and further loss of available bandwidth due to retransmission overhead which can consume up to 30-40% of that bandwidth since there is no guaranteed delivery possible on those legacy devices. Industrial organizations have notoriously small budgets, and tools which create a choke point on network throughput or are otherwise prohibitively expensive and complex simply cannot be used in most of those environments. Many have had to abandon data diodes because they are not able to justify the cost/performance benefit.

“What makes NetWall USG attractive to our customers and a more unique data diode is that we leverage multiple patent-pending techniques to ensure guaranteed delivery and multiplexed connections to deliver throughput as fast as 1 gigabit/sec,” said Toby Weir-Jones, Chief Product Officer at Bayshore Networks. “We use standard, commercial off the shelf (COTS) hardware for the base systems, which reduces cost, and implement our protocol break across dedicated high-speed serial interface cards installed in each system. We also apply our high-performing industrial content inspection engine that allows us to analyze files and data in-transit and apply policy enforcement if desired, to deny and quarantine unauthorized or unsafe file transfers.”

Instead of only larger, highly funded organizations having access to data diode technology, NetWall USG now increases the accessibility of this technology to a much wider audience, delivering affordable, high-performing data diode technology for all industries and sizes of companies. The 1-gigabit NetWall USG device is less than half the price of competing 100-megabit devices in many cases.

The NetWall USG Industrial Airgap Bridge features include:

  • Easier to bridge the airgap without burdensome security measures
  • File transfers and server replication from trusted to untrusted networks with guaranteed delivery and provable file validation
  • Hardware-enforced one-way only communication – no network connectivity back into the trusted plant environment
  • Bandwidth-efficient, does not use bandwidth-intensive retransmission methods
  • High performance, 1 gigabit/sec with content-inspection and policy enforcement for data in-transit
  • Budget friendly, very high price:performance ratio
  • 2x1U 19” rack-mountable hardware delivered pre-loaded with software and with hardware dongles for secure management.

NetWall USG security solution is available for order now, with shipment available by July 15, 2020. For more information on the product, visit our website at or contact for pricing and availability. Check out our blog on the technology at
