ISA/IEC 62443 is the international standard series for security in industrial automation and control systems (OT/ICS/SCADA). Developed by ISA - International Society of Automation in collaboration with IEC, the standards help companies protect critical processes from cyber threats - with a focus on availability, integrity and safe operation.
Operational Technology (OT) is the systems that control physical processes in production, energy, water, transportation and more. OT security is about protecting these environments from cyberattacks and unauthorized access - without compromising uptime and safe operations.
Access control: Only authorized users and service providers are granted access.
Network security: Segmentation, monitoring and secure connections between zones/systems.
Policies & procedures: Clear operations manual adapted to the OT environment.
Vulnerability management: Identification, prioritization and secure patching/compensation checks.
Monitoring & incident management: Continuous monitoring and clear IR flows for OT.
ISA/IEC 62443 is often the framework for OT security - and here we are among the leading consultants in Denmark.
We help you put ISA/IEC 62443 into practice - from maturity assessment to design, implementation and operation:
Risk assessment & consulting: Asset, threat and vulnerability mapping and prioritized treatment plan.
Security architecture: Segmentation/zones & conduits, access control, logging/monitoring and emergency response - designed according to 62443 requirements.
Education & training: Targeted courses for management, operations and technology to ensure processes are followed in everyday life.
Frontdoor Security participates in the work with ISA/IEC 62443 in Denmark and has specialists with deep OT experience. René Matthiassen is responsible for ISA in Denmark.
