By 2026, talking about the IoT as simply ‘sensors connected to a network’ will be a thing of the past. Previously, many companies followed a simple logic: install a few meters, sensors and controllers, and connect them to SCADA or a separate data collection system. At best, this provided local visualisation and a few reports, but did not change the approach to process management.

Today, especially in the context of war and constant risks, this is clearly no longer enough. It is important for businesses not just to ‘see the figures’, but to have a managed ecosystem that transforms data into rapid, informed decisions: when to shut down equipment, how to optimise energy consumption, how to switch loads, and how to operate in the event of a loss of connection or power.

The risks of war, and the need for security and speed

The modern IoT ecosystem is an approach that ensures resilience, security and rapid response. For Ukraine, this is of particular importance for several reasons:

• infrastructure operates under constant threat: damage to energy facilities, disruption of communication channels, power cuts;
• the number of cyber threats to industrial and energy systems is growing: attacks on control networks, attempts to interfere with technological processes;
• businesses need solutions that not only collect data but also allow for rapid changes to operational scenarios – switching to backup lines, managing load, and monitoring equipment status in real time.

In such conditions, the IoT as a ‘set of devices’ does not deliver what is required. Therefore, the focus is shifting: from simply ‘connecting everything possible’ to building an ecosystem where every layer – network, devices, platforms, analytics, security and operational procedures – works in harmony.

The IoT ecosystem in practice

A mature IoT ecosystem consists of several interconnected layers:

1. Connectivity and infrastructure. A reliable, segmented network that accommodates various access scenarios: local, remote and backup. In industry, this is often a combination of wired networks, industrial Ethernet, radio channels, mobile communications, private networks, etc.
2. Devices and the ‘network edge’. Equipment capable not only of sending data ‘somewhere to the centre’, but also of processing some of the information on-site – to make local decisions even when connectivity is unstable. This is particularly important where there is a risk of channel loss.
3. Data collection and processing platform. The single ‘source of truth’ where data from various sites and systems is consolidated, cleaned, analysed and visualised. This can be a cloud-based or hybrid platform – the key is that it supports scalability and integration with existing systems.
4. Security and access management. Policies, access control measures, segmentation, event monitoring, protection of communication channels and the devices themselves. Without this, any connectivity becomes an additional attack surface rather than an advantage.
5. Integration with business processes. Something that is often overlooked. Data must be ‘embedded’ in processes: planning, maintenance, energy management, logistics, and risk management. When IoT solutions are not integrated into processes, they remain nothing more than a ‘pretty picture on a screen’.

The difference between a large number of sensors and a mature ecosystem lies precisely in the presence of these levels and the manageability of the entire structure.

The reality in Ukraine

In recent years, there have been numerous examples in Ukraine where the approach to the IoT and industrial networks has changed significantly as a result of the war:

• energy companies are forced to develop more resilient monitoring and control systems that continue to function even when the network and equipment are damaged;
• critical infrastructure operators are tightening requirements for resilience and security, recognising that ‘isolation’ no longer guarantees protection;
• businesses operating in manufacturing and logistics are seeking ways to rapidly restructure supply chains and production routes, relying on real-time data from sites.

Many companies already have parts of this ecosystem: some have modern network infrastructure, others have an analytics platform, and others have good security practices. The task for 2026 and beyond is to weave these elements into a cohesive system.

Practical recommendations

If you already have connected equipment, monitoring systems or local IoT projects, it is worth checking at this stage whether your ecosystem is ready for growth and operation in high-risk environments.

What you should do today:

• take stock of what is already connected and identify any ‘blind spots’;
• assess how security is organised: access controls, segmentation, working with remote contractors;
• identify where data is actually used for decision-making and where it simply ‘ends up in an archive’;
• identify 1–2 priority areas where a shift to an ecosystem approach will yield tangible results – for example, reduced downtime, energy savings or better control over distributed assets.

And moving forward – plan development not as a set of separate projects, but as the construction of a coherent, sustainable and secure IoT ecosystem capable of operating in the reality of 2026, rather than in a hypothetical ‘ideal world’.

The networking component forms the backbone of a mature IoT ecosystem, as it ensures reliable communication between sensors, controllers, analytics platforms and business applications, even in the event of channel loss, power outages or distributed infrastructure. For industrial scenarios, this cannot be achieved without specialised network devices that support industrial protocols (Modbus, Profinet, Ethernet/IP, etc.), OT network segmentation, traffic protection at the switch and router level, and integrated cybersecurity based on Zero Trust principles and the ISA/IEC 62443 standard – this is precisely the focus of Cisco Industrial IoT, with its portfolio of industrial switches, routers and OT security solutions.
