A Network is an Ecosystem: Rethinking Security for OEMs
In a recent conversation with Anthony Besett of GetWireless, a metaphor emerged: a network is not just a collection of devices, but an ecosystem. The line is as catchy as it is directional: original equipment manufacturers (OEMs), a foundational contributor to global supply chains, have a growing responsibility for securing today’s interconnected environments early in design. How did we get here? Well, we live in a connected world. According to IoT Analytics, which tracks and analyzes IoT connectivity, the number of connected IoT devices will grow 14% by end of 2025, reaching 39 billion in 2030 and more than 50 billion by 2035. That’s six devices for every single person on earth. Another way to frame this: 73.2% of the world’s population accesses the internet. A parade of innovative technologies have arrived: artificial intelligence (AI) infrastructure, hyperscalers (developers scaling data center networks), quantum computing, and the data center surge. Deloitte ranks “cyber and/or physical security concerns” as number three on its list of data center infrastructure challenges, tapping OEMs on the shoulder to take note of technology’s evolving impact. Besett serves as Vice President OEM Embedded Solutions for GetWireless, a leading value-added distributor of cellular solutions like intelligent gateways, servers, asset trackers, modems, and other solutions for IoT applications. Besett predicts that OEMs focusing only on designing, making, and selling products may be shortsighted. IoT devices are increasing and networks are becoming more complex. The stakes for robust, holistic security have never been higher – and OEMs recognizing that their products are responsible for the entire network ecosystem will be the ones to differentiate their product. Intentional security for OEMs is a bold leap forward for customers. Beyond Silos: A Network as a Secure Ecosystem Besett emphasized that traditional approaches to security often focus on isolated components, protecting a gateway here or running penetration testing (pen testing) there. He says, “We have to be paying attention to security across the entire infrastructure, not just one piece of it. Historically, you’ve seen there’s attention to one piece.” Many of GetWireless’s suppliers do pen testing, for example, but Besett sees that changing in the future with security-minded solutions that are guaranteed to protect networks and all the devices that go beyond that point. Here’s why: in an ecosystem, every element is interdependent. A vulnerability in one device – like a sensor, workstation, or camera – threatens the health of the entire network. Just as the rapid spread of Dutch Elm Disease endangers a forest, a single weak link in a network can compromise an entire digital environment. As an example, consider the Mars Hydro breach. The China-based maker of LED grow lights had 2.7 billion records exposed, including passwords, IP addresses, and device IDs, all because the attacker was in Wi-Fi range. OEM manufacturers have an opportunity to help mitigate the risks of IoT data breaches. Besett shares, “I was in a conversation not too long ago where a customer’s whole network was hacked because somebody plugged into a gateway that wasn’t controlled. And so now you’ve got a hole. There are lawsuits. It’s going to be a mess.” He says fragmented security leaves the entire network ecosystem exposed. The takeaway for cybersecurity: silo thinking is risky when it comes to individual OEM network products. A piecemeal approach is no longer sufficient. Zero Trust Security and Zentry Besett points out the value of zero-trust architectures, such as the FreeWave Zentry™ solution. Referencing back to his customer example, he explains, “There were vulnerabilities there that if something like Zentry was on that, that wouldn’t have happened because they (the attacker) would have actually had to request access.” “The devices on the edge, sensors, the workstations, the PCs, the tabs, the LPRs, all those different things, they get security as well. And it’s really cool because Zentry controls who has access, when they have access, and exactly what they have access to. What’s so unique about Zentry and their kind of ‘look’ on the infrastructure is . . . giving the control to an OEM to be able to secure everything for their customers, not just one piece.” Security must extend to every part of the network ecosystem, he says. It’s not enough to lock the front door; every window, back door, and fence line needs protection. The FreeWave Zentry solution secures not just one component but the entire deployment by making the attack surface invisible – there are no public IP addresses, open ports, or static tunnels to scan or exploit. Ephemeral sessions mean access appears only when needed and disappears when complete, leaving no standing exposure. Deterministic control removes noise, helping small security teams focus on real threats without wasting time on no false positives. Besett explains, “Zentry controls who has access, when they have access, and exactly what they have access to.” This Identity-driven access ties every connection to a verified user, device, and policy for precise control. Devices, from license plate readers to medical wearables, become ubiquitous and integral to securing critical operations. At GetWireless, Besett says the company looks at the entire connected world, including body wearing devices, POS machines, monitoring cameras, and weather stations. “We’re engaged at all those different levels in the community,” he says. Security, according to Besett, is no longer a “nice-to-have” but a fundamental requirement for any device that connects to a network. He notes, “Do you want to be the hole in the network that creates the problem for a customer or brings down a network?” The risks are real, from lawsuits to national infrastructure threats. Zero trust gives OEMs an opportunity to proactively address vulnerabilities at every layer, not just at the gateway or a single device, but across the entire ecosystem. What OEMs Need to Know About Zero Trust Security is poised to become a differentiator in the marketplace. With many devices becoming commoditized, Besett suggests that embedding zero trust could set OEM network products apart. Besett asks a good question: “Why would you choose a device that doesn’t meet
Ditch the Wires, Keep the Power: FreeWave ZU1100 – The Smart Wireline Replacement Solution
IIoT often lives in harsh environments where trenching equipment, excavators, and backhoes can be challenging and expensive to operate. Costs escalate based on trench length and depth, soil type, post-trenching land restoration, permitting costs, and regulatory requirements. Then there are maintenance considerations once copper wire is in the ground. If wire breaks underground, how do you know where the problem is? In places like the American West or Canada, where wild fires exist, wires require flame-retardant, or self-extinguishing jackets. High-temperature environments, chemical exposure or flood zones also require extra maintenance for underground wire. Rising copper prices pose a rising theft risk too – a billion dollar industry annually according to Nasdaq – where criminals trade stolen copper for profit, putting critical infrastructure at risk. “Aging, trenched wired infrastructure is a high risk. You need to get in front of the problem because it’s not a matter of ‘if,’ it’s a matter of ‘when’ that wired infrastructure will fail,” said William H. Conley, III, director of technical and customer support at FreeWave. That risk is highest for legacy industries like oil and gas, utilities, and water wastewater treatment. As digitalization increases, reliably transmitting analog and digital input/output (I/O) and sensor data across long distances becomes even more critical. Traditionally, as an example, transmitting 4-20mA signals over long distances has required trenching miles of shielded twisted pair (STP) wire. In the past, trenching of wire signals has been a costly and maintenance-heavy process. Enter ZumEdge® ZU1100. FreeWave’s latest wire replacement solution is designed to make buried wire a thing of the past and industrial analog and digital I/O and sensor data flow. What Is ZU1100? Wire replacement solutions aren’t new. Many companies offer solutions that are deployed in a lot of networks, today. However, the ZU1100 IS different. It is a bi-directional I/O wireless solution that replaces labor-intensive wired connectivity for customers in industrial sectors. The best part is a hallmark of FreeWave’s design philosophy: install it and it just works. It’s pre-configured so you literally plug it in and it works. ZU1100 mirrors analog and digital signals from one point to another, eliminating the need for physical wiring. Whether you’re monitoring a remote water tank’s level or controlling a pump miles away, ZU1100 transmits real-time analog and digital I/O and sensor data, to include 4-20mA signals current loops over distances of up to 20 miles, or farther in some instances. The DIN-mountable device is sleek, measuring about the size of your favorite summer read. It supports two analog inputs/outputs and two digital inputs/outputs on each end, enabling two-way communication between field equipment and control systems. Being able to quickly analyze and respond to data variations is one of the paramount benefits from FreeWave solutions. What’s better is that FreeWave is no stranger to radio technology. We’re trusted. Since 1993, FreeWave has led the way with more than 800,000 units in use around the world sending telemetry data to users. As data has evolved, thousands of customer conversations led to innovating the an evolved solution that truly scales. Unlike previous one-way solutions, the ZU1100’s bi-directional design allows for peer-to-peer and, soon, peer-to-multi-peer relationships (with its ability to support up to 32 remote devices in future updates). Future features include support for additional protocols and system integration for streamlined workflows. “How industry collects information is identical across markets such as oil and gas, utilities, water/wastewater, and building automation,” said Conley. Add to the list industries like agriculture, smart cities, chemical processing, and manufacturing. When industry requires analog I/O signals, they prefer 4-20mA current loops. Why? Because the signal is almost immune to electrical noise and interference, delivering reliable signals. “It’s the same analog and digital I/O signals, the same protocols like Modbus and MQTT (that many industries use). What might differ is the regulatory requirements and the type of command and control,” said Conley. Even there, ZU1100 is prepared – for anything. Conley said that FreeWave designs solutions to the “absolute most challenging scenario.” ZU1100 is industrial grade: Class I, Division 2-certified (C1D2). It can operate in temperatures from -40°C to +75°C and is explosive proof – a must-have for oil and gas customers. Along with ease of use, security is another signature design element in FreeWave solutions. AES encryption is available on ZU1100, with future plans for enhanced network security via FreeWave Zentry™, a secure connectivity solution introduced by FreeWave earlier this year based on zero-trust principles. Future integration of AI and advanced protocols are also on ZU1100’s ideation board. ZU1100 Use Cases Field technicians, administrators, integrators, and partners in industrial sectors wrestling with wired sensor systems have a number of use cases that highlight ZU1100’s plug-and-play installation, bi-directional I/O, and rugged, reliable performance. Here are three high-impact use cases: Industrial Monitoring A remote water tank with sensors measures level, pressure, and pump current, all while feeding into a programmable logic controller (PLC). ZU1100 transmits signals wirelessly for remote monitoring and control. Automated Control Devices are connected in real-time so operators send commands such as turning on a pump or shutting down a system based on sensor readings – without the need to trench and maintain long runs of physical wiring. This use case is ideal for industries where assets are distributed over large, hard-to-wire areas. ZU1100’s bi-directional monitoring and remote actuation increases operational efficiency and reliability. Protocol Bridging and Legacy System Modernization ZU1100 helps organizations transition from legacy systems using protocols like Modbus to modern IoT protocols such as MQTT. (According to a 2022 survey by HiveMQ, 50% of respondents use MQTT as a standard protocol.) ZU1100 can bridge analog/digital, I/O and serial/Ethernet protocols so data flows between old and new equipment, allowing gradual modernization, and supporting both legacy and next-generation protocols. What’s Next? At FreeWave, our vision is to make receiving and sending data easy. It’s a world where we see IIoT being scalable, smart, and simple. ZU1100 is a next-generation, customer-driven solution that bridges the gap between legacy systems and future-ready industrial automation. The solution creates connected, intelligent, and
