Security specialists have become key partners for industrial operators as OT environments become more connected.
Major trends in the industry
AI and IoT Are Combining
This is a huge trend. The enterprise IoT market is headed toward what industry analysts call the “agentic and AI phase” of maturity. AI accelerators are being embedded in hardware by device makers. Connectivity is more and more pervasive and less and less evident. And software is more assistive, slowly moving toward self‑optimizing orchestration.
Edge AI has been a hot topic at industry events such as MWC, with the idea of doing more data processing on the device rather than sending it back over the network. This is critical for industrial use cases where latency, bandwidth, and data sovereignty are real concerns.
Edge Computing Is the New Normal
The shift from cloud-only to edge computing is gathering steam. For time-sensitive applications (autonomous systems, grid automation, safety monitoring), processing data at the edge reduces latency in ways that matter operationally. Edge gateways and industrial edge servers are becoming the key component of IIoT architecture.
Digital Twins Are Here
Digital twins have graduated from pilot projects to operational tools. One example is Siemens’ Digital Twin Composer, which allows companies to create photorealistic virtual representations of plants and test scenarios before they’re put into place. ABB and other automation vendors provide similar capabilities.
Private Wireless Networks and 5G
Industrial Ethernet, private wireless networks, and 5G are expanding connectivity options for factories, ports, mines, and utilities. Cisco industrial routers now support 5G, and module vendors are moving to RedCap and eRedCap migration for low-power IoT applications.
Industrial Cybersecurity Is a Requirement
As OT systems become more connected, cybersecurity has evolved from a supporting function to a core design requirement. Industrial operators must take into account the EU Cyber Resilience Act and other frameworks, identity and access control, network segmentation, and vulnerability management, among others. This has led to increased demand for security vendors such as Nozomi Networks, Dragos, and Forescout.
How to Choose a Smart IoT Company for Industrial Applications
If you’re evaluating IoT partners for an industrial project, here are a few things to consider.
Hardware capability. Does the company offer equipment that can handle your operating environment? Look at industrial temperature range, protocol support, and reliability specifications. Not all hardware is built for factory floors or outdoor installations.
Edge intelligence. Can the device process data locally? Protocol conversion, data filtering, and local decision‑making reduce dependence on cloud connectivity and improve response times.
Connectivity options. What does the device support? Ethernet, 4G/5G, LoRaWAN—the right mix depends on your deployment scenario. If you’re working in remote locations, cellular or LPWAN matters more than Wi‑Fi.
Integration with your existing stack. Does the solution work with your current PLCs, SCADA systems, and cloud platforms? Open standards like OPC UA and MQTT make integration easier.
Security. Look for devices and platforms that follow established security standards. This is especially important if you’re in a regulated industry.
