NEW YORK, Nov. 12, 2020 /PRNewswire/ -- Garland Technology, a leading provider of network TAP, packet broker, and cloud visibility solutions, and Nozomi Networks, the leader in OT & IoT security, today announced a partnership to unify visibility and security across managed and unmanaged IoT devices for critical industrial networks worldwide.
Industrial operational technology (OT) networks are vulnerable to cyberattacks through connections to the Internet of Things (IoT), as well as the convergence with traditional IT networks. The joint solution enables complete connectivity, visibility, and cyber resilience across distributed networks. Before disrupting operations, changes in the network are quickly discovered for the response to cyber threats, risks, and anomalies.
"Getting packets from OT networks to security tools like Nozomi Networks' Guardian starts with connectivity. OT environments are different from IT networks, requiring specialized network TAPs and accessories connecting tools to the network," states Chris Bihary, CEO Garland Technology. "Our OT solutions are ideal for networks prone to small spaces, vibration, extreme temperatures, DC power, data diode requirements, and fast Ethernet connections. We understand these distinct infrastructures and we are excited to work with Nozomi Networks to secure global industrial networks."
The deployment of Nozomi Networks and Garland Technology enhances visibility and security for advanced utilities, oil and gas facilities, automotive, and other industrial infrastructures. With the ability to collect data across all locations, the joint solution delivers a centralized source of aggregated networking information from Garland's solutions. Nozomi Networks Guardian delivers network visualization, asset inventory, vulnerability assessment, and threat detection in a single application, for effective connectivity across OT and IT teams.
"Protecting your operation from threats and process anomalies requires deep packet-level visibility and accurate, real-time analytics," said Chet Namboodri, Nozomi Networks Vice President, Worldwide Business Development & Channel Sales. "We're excited to work with Garland Technology so customers can easily leverage our combined solutions for visibility and complete packet information continuity and connectivity in OT and IoT environments."

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.
If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.
While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.
Some of you may have noticed a flaw in the logic behind this solution! You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.
Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.
Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.
Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
