This guide sets out the biggest Internet-of-Things threats in 2026 — from hijacked cameras and sensors to devices conscripted into botnets — and how organisations can respond. IoT is now everywhere in business, and each device is a potential foothold.
What it means for you
The recurring problem is that connected devices ship with weak default settings, rarely get updated, and often sit on the same network as everything else — so one compromised gadget can become a route to critical systems.
The playbook: inventory your connected devices, change defaults and update firmware, and isolate them on their own network segment. Our Secure Your Internal Network service is designed to contain exactly this kind of risk.
The IoT problem in detail
Connected devices — cameras, sensors, door controllers, smart TVs, building-management kit — have quietly become some of the least-governed technology in most organisations. Many ship with default passwords, receive few or no security updates, and stay in service for years after the manufacturer stops supporting them. Worse, they are often plugged into the same flat network as laptops and servers, so a single hijacked camera can become a quiet foothold for reaching far more valuable systems, or be conscripted into a botnet used to attack others.
A practical IoT plan
Begin with discovery: you cannot protect what you do not know is there, and “shadow” devices are common. Change default credentials, update firmware where possible, and disable features and remote access you do not use. Crucially, place IoT devices on their own isolated network segment so that if one is compromised it cannot reach your core systems, and monitor that segment for unusual traffic. Retire devices that can no longer be secured. Our Secure Your Internal Network service is designed to contain exactly this kind of risk.
Treat every connected device as a computer in its own right, because to an attacker that is exactly what it is.
