IoT Security —
operating connected devices securely

IoT Security (Internet of Things Security) refers to the protection of connected devices — from machine sensors and edge gateways to cloud-based analytics platforms.

In production environments, this is often referred to as Industrial IoT (IIoT). These devices are often poorly patched, weakly authenticated, and directly connected to critical OT networks — an attractive target for attackers.

IoT security and OT security go hand in hand: those who consider both together protect their production, data, and business models equally.

— Typical Risks & Countermeasures —

Insecure default passwords — replace with strong authentication

Outdated firmware — structured patch & lifecycle management

Direct internet access — implement segmentation and firewalls

Lack of visibility — continuous asset & anomaly monitoring

IoT vs. OT Security — what is the difference?

OT security addresses classic control technology such as PLCs, SCADA systems, and industrial plants. IoT security focuses on the growing number of connected sensors, actuators, and smart devices. In the modern factory, the boundaries are blurring — IIoT is part of OT.

You can find an in-depth view of the OT perspective in "OT vs. IT Security" and in our introduction "What is OT Security?".

How we secure IIoT in production

Our Managed OT Security Service also takes connected IoT devices into account. With Asset Management we create transparency, with Network Intrusion Detection we detect anomalies early — passively and without interfering with production.
