ISA/IEC 62443 Industrial Automation and Control Systems Security compliance software
Evidence industrial cybersecurity against ISA/IEC 62443 — from the security programme to the seven foundational requirements for control systems.
What ISA/IEC 62443 requires
ISA/IEC 62443 is the international series of standards for securing industrial automation and control systems (IACS) — the operational technology running energy, water, manufacturing, transport and other critical processes. It addresses asset owners, integrators and product suppliers across the OT lifecycle.
The series defines a security programme for asset owners (62443-2-1), technical system requirements organised as seven foundational requirements (FR1–FR7: identification & authentication, use control, system integrity, data confidentiality, restricted data flow, timely response to events, resource availability), and the concepts of zones, conduits and security levels for architecting defence.
OT environments cannot simply adopt IT controls: availability and safety dominate, patch windows are scarce, and legacy equipment persists for decades. 62443 provides the discipline regulators and insurers increasingly expect — and in the Gulf it complements NCA obligations such as the ECC's ICS domain and OT-specific controls.
Who it applies to
- Asset owners operating industrial control systems (energy, water, oil & gas, manufacturing)
- System integrators building and maintaining IACS environments
- Critical infrastructure operators with OT regulatory obligations
- Product suppliers aligning components to 62443-4-x expectations
At a glance

How GRCLens supports ISA/IEC 62443
ISA/IEC 62443 runs on the same shared control model as every other framework in GRCLens, so evidence captured once can satisfy several obligations at the same time.
Programme + FR assessment
The security-programme requirements and FR1–FR7 are pre-loaded as assessable controls with OT-appropriate guidance and deliverables.
Owners across IT and OT
Assign controls to plant, engineering and security owners — accountability that matches how OT is actually run.
Evidence for zones and conduits
Attach architecture diagrams, segmentation evidence and security-level rationale to the controls that require them.
Alignment with ECC and 27001
OT controls are mapped to overlapping ECC and ISO/IEC 27001 obligations so shared evidence is reused.
ISA/IEC 62443 frequently asked questions
Who should use ISA/IEC 62443?
Asset owners, integrators and suppliers involved with industrial control systems. GRCLens focuses on the asset-owner view: the security programme and the foundational requirements applied to your zones and conduits.
What are security levels?
62443 defines SL1–SL4, expressing the capability needed to resist increasingly sophisticated attacks. Target levels are set per zone based on risk, and GRCLens evidences the controls supporting the chosen level.
How does 62443 relate to NCA-ECC?
The ECC includes ICS controls for Saudi entities; 62443 provides the deeper OT discipline behind them. Managing both on one platform reuses shared evidence.
Is certification available?
Product and programme certifications exist through schemes such as ISASecure, run by certification bodies. GRCLens supports assessment and evidence, not certification itself.
