IEC 62443 covers OT security for asset owners, system integrators and product suppliers, zones and conduits, security levels, secure development and component requirements. Parts can be certified. We use it to design OT security programmes for manufacturing, energy, water and oil and gas, connected to ISO 27001 governance.

## Who it is for

- Asset owners with industrial control systems
- System integrators

## How Secure iQube helps

1. **Gap assessment**: We compare what you do today with every requirement and control, then give you a prioritised gap report and a realistic timeline.
2. **Design and documentation**: Scope, policies, procedures, risk methodology and records, written to fit how your teams actually work, not a template binder.
3. **Implementation and training**: We help owners put controls in place, train the people who run them and start collecting evidence.
4. **Internal audit and management review**: An independent internal audit and a structured management review prove the system works before the certification body looks at it.
5. **Certification audit support**: We prepare you for Stage 1 and Stage 2 with your chosen accredited certification body and help close any findings quickly.
6. **Surveillance and continual improvement**: Optional managed support keeps evidence current through annual surveillance audits and the three-year recertification.

## Frequently asked questions

### Can we certify to IEC 62443?

Yes. Several parts, such as secure product development and component requirements, support certification by accredited bodies.
