IEC 62443
IEC 62443 - Industrial Automation and Control Systems Security
Reference standard for cybersecurity of industrial automation and control systems (IACS). Defines zones, conduits, security levels (SL 1-4) and requirements for asset owners, system integrators and component suppliers. Applicable to manufacturing, energy, oil & gas, water, building automation.
- 01Zone and conduit segmentation (62443-3-2)
- 02Foundational Requirements (FR1-FR7): identification, use control, data integrity, confidentiality, restricted flow, timely response, resource availability
- 03Risk assessment and Security Level Target definition
- 04Documented patch and vulnerability management
- 05Continuous monitoring of OT network integrity
MON5 is OT-native: it recognises industrial protocols (Modbus, S7, EtherNet/IP, OPC UA, IEC 61850, DNP3 and more), identifies real zones and conduits from observed traffic, and provides technical evidence on FR1-FR7. From PROTECT up, CVE/EPSS correlation and advanced anomaly detection support higher SL-T on critical assets.
- →Native OT / ICS protocol recognition
- →Zone and conduit map based on real traffic
- →Documentable technical evidence for FR1-FR7
- →Patch management informed by CVE + EPSS scoring
- →IEC 62443 reporting (advanced in the ADVANCED tier)
Let's figure out what you really need.
Show us the OT perimeter and the regulations you need to cover: we will tell you what MON5 documents directly, where complementary work is needed, and which tier to start from - no hard selling.
