Top 10 Industrial Cybersecurity Companies in Europe

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.

Final Thoughts

Industrial security is not a niche in the world of cybersecurity. It is a fundamental need of businesses in the UK and Europe that deal within the industries where even a few minutes’ loss of services can plunge them into serious financial and market loss. These cases further increase the reliance on Industrial Cybersecurity Companies in Europe.

Selection of a cybersecurity partner is more than a set of tools. It translates to playing along with groups familiar with the real-time operation activity, regulatory sensitivity, and modern-day OT environment complications of the legacy versus modern system.

Qualysec, as an example, provides both automated and manual pentesting and the undoubtedly stated goal of alignment with the two standards, NIS2 and IEC 62443. This provides the firms with the security that their defences not only are role-proofed, but they are also audit-ready in the context of being European-compliant. The quality that makes them shine in an overcrowded market is the capability to present true-to-life threat vectors in SCADA systems, PLCs, and other industrial technologies.

Be it preventing a serious fault during a compliance audit, preventing a serious failure, or even developing a longer-term resilience plan, the appropriate cybersecurity partner can make it happen. The companies mentioned in this blog are ensuring that industries transition towards proactive cyber security as opposed to reactive countermeasures. That switch is all in the increasingly dynamic threat environment.
