Align IT and OT security with one consistent control approach
ISO27001 is the Internationally recognised framework for Information Security best practice. IEC62443 is its internationally recognised counterpart framework for Operational Technology Cyber Security.
When mapped effectively, both ISO27001 and IEC62443 can work in parallel, providing an organisation with greater controls and security measures, and thus further mitigating down Cyber Risk, across both their existing IT and OT infrastructure.
- IEC62443 and ISO27001 provide guidance for the identification and mitigation strategies of OT and ICT security risk
- Creates consistency of approach across an organisation by combining the frameworks
- Defines roles for asset owners, system integrators, and component suppliers, ensuring that all parties involved in the supply chain contribute to security.
- Perfect for organisations who maintain both traditional IT corporate infrastructure and Operational Technology estates
- Format: framework mapping and control alignment across IT and OT
- Duration: mapping delivered in weeks, with optional follow-on support
- Audience: IT, OT, risk, compliance, asset owners and delivery partners
- Ideal for: organisations operating both corporate IT and OT environments
- What's included: framework mapping, control alignment, role clarity, reporting and next steps
