As industry rapidly digitizes, cybersecurity has become a crucial factor in protecting critical societal functions. Industrial cybersecurity, also known as OT security (Operational Technology security), is about securing the systems that control factories, power grids, water plants, and other infrastructure. It is no longer a question of if an attack will occur, but when.
Historically, industrial control systems have been isolated from the internet. With increased integration between IT and OT, for example through SCADA systems and cloud services, the attack surface has grown dramatically. This means that traditional security solutions are no longer sufficient.
Cyberattacks like Stuxnet, Triton, and Colonial Pipeline have shown how vulnerable industrial environments are. An intrusion can lead to production standstills, environmental disasters, or even threaten human lives.
To address the threats, international standards are often used such as:
IEC 62443 – Management system for cybersecurity in industrial automation systems
NIST CSF 2.0 – framework for risk-based cybersecurity
ISO 27001/27002 – information security and management system
These frameworks help organizations conduct GAP analyses, define controls, and build security programs tailored to the needs of the business.
Industrial cybersecurity requires cross-functional teams with expertise in:
Penetration testing of OT environments and OSINT
IT/OT architecture
Risk and vulnerability analysis
Incident handling (DFIR)
SIEM and threat detection
The demand for specialists with experience in ICS (Industrial Control Systems) and OT is high. The role requires both technical expertise and strategic understanding – a combination that is hard to find.
We help many well-known companies of all sizes with the experience and expertise needed to support the implementation of systematic OT security.
Each customer has their challenges and needs, which is why we have developed an adaptable method for implementing a long-term strategy for OT cybersecurity. This allows each customer to systematically address their own issues regarding industrial cybersecurity, regardless of industry and size.
Several of our customers are large multinational companies with operations and factories on all continents. Defensify often support our customers globally on-site when required.
Industrial cybersecurity is no longer a niche – it is a strategic necessity. To protect our societal functions, investments in technology, expertise, and collaboration are required. It is time to take cybersecurity seriously – before it's too late.
