The recent integration of IT and OT systems makes industrial cybersecurity an area that is gaining momentum in Europe considerably faster. In a 2024 ENISA report on the Threat Landscape 2024, it was found that more than 46 percent of cyberattacks in the EU were DDoS-related, second only to ransomware and data breaches. In such industries as energy, manufacturing, and transport, where operational downtime is equivalent to a direct financial loss and associated reputational damage, this tendency proves to be particularly strong and showing the growing need for Industrial Cybersecurity Companies in Europe.
Industrial cybersecurity firms based in Europe have been an invaluable resource to any company that is interested in the security of vital infrastructure. Advanced network segmentation and threat detection, secure remote access, and incident response are among the services offered by those firms, which combine IT and OT security competencies to address the variances of industrial environments.
This blog highlights the Top 10 industrial cybersecurity companies in Europe, showcasing their key cyber security services, specialisations, and what makes them stand out. It also explains how to choose the right partner for OT‑centric environments and meet both operational and regulatory demands in the UK and EU sectors.
What Is Industrial Cybersecurity and Why Does It Matter
Industrial cybersecurity refers to the procedure of safeguarding Operational Technology (OT) systems, including SCADA, PLCs, DCS, and industrially-deployed IoT devices, against cyber threats. Such systems regulate the physical processes of these industries, such as energy, production of goods, transportation, water treatment, and many others.
Unlike the more common IT systems, OT may use legacy systems, initially designed with no direct access to the internet or ability to be administered remotely. With the higher level of our systems becoming digitalised and connected to IT networks, the attack surface increases, which makes the systems more susceptible to ransomware, malware, phishing, and even state-sponsored attacks.

What makes industrial cybersecurity unique?
- Safety risks are real: A hack in a chemical plant or power grid can cause a physical injury, environmental destruction, or national disruption as a result.
- Downtime is costly: Downtime, even of a few minutes in a manufacturing plant, can cost the company six-figure losses.
- Compliance is strict: Many sectors in Europe are governed by NIS2, IEC 62443, and local country-specific regulations, requiring regular risk assessments and vulnerability management.
Because of these factors, choosing the right industrial cybersecurity partner is not just about software. It is about securing complex, safety-critical operations.
