ISO 27001 for industrial manufacturers — with OT/ICS at the core.
Most ISO 27001 tooling assumes a pure IT scope. Manufacturing cybersecurity is 60% OT/ICS. Matproof extends ISO 27001:2022 with IEC 62443, aligns with TISAX for automotive, and maps to NIS2 Annex II manufacturing obligations.
Why this matters now
Ransomware on manufacturing production lines in Europe 2023-2025 ran into the hundreds of millions in damage. Insurers now require ISO 27001 evidence. OEM supply chains demand it from tier suppliers.
- Legacy ICS systems pre-date modern security — patching and logging are hard
- IT/OT convergence increases attack surface without unified governance
- Automotive supply chain requires TISAX AL2 or AL3 alongside ISO 27001
- Remote maintenance vendors introduce supply-chain risk
How Matproof covers ISO 27001 for Manufacturing
Scope definition with OT inclusion
Your ISO 27001 ISMS must explicitly include OT systems where they process information or impact security. Matproof helps define scope boundaries that are defensible to auditors.
IEC 62443 integration
ISO 27001:2022 Annex A controls mapped to IEC 62443 Zone and Conduit model. Shared evidence for both certification regimes.
TISAX alignment
Dual certification approach: one ISMS, evidence satisfies ISO 27001:2022 and TISAX Information Security Assessment (ISA) simultaneously. Common in automotive supply chain.
NIS2 Annex II readiness
Manufacturing is important entity under NIS2. ISO 27001 is the foundation. Matproof shows the NIS2-specific gaps on top of ISO 27001 coverage.
In scope
- Discrete and process manufacturing
- Automotive suppliers (tier 1, 2, 3)
- Aerospace and defense manufacturing
- Food and beverage production
- Chemical and pharmaceutical manufacturing
- Electronics and semiconductor fabrication
Frequently asked questions
Should my ISO 27001 scope include production OT systems?+
If OT systems process or protect information relevant to your ISMS (intellectual property in PLCs, production data, quality records), they should be in scope. If they're purely analog or information-free, they can be excluded. Most modern production is borderline — auditors typically expect OT inclusion. The Statement of Applicability should justify your scope decision explicitly.
How does ISO 27001 relate to TISAX for automotive suppliers?+
TISAX uses the VDA ISA (Information Security Assessment) catalog, which is ~80% aligned with ISO 27001 Annex A. ISO 27001-certified organizations meet most TISAX-required controls with minimal additional work. TISAX adds automotive-specific expectations: prototype protection, data classification with OEM-specific labels, external audit by TISAX-accredited auditor. Typically 3-6 months additional effort after ISO 27001.
What's the overlap with NIS2 for manufacturing?+
Manufacturing is NIS2 Annex II (important entity) if you exceed 50 FTE or EUR 10M turnover. ISO 27001 covers ~75% of NIS2 Art. 21 measures. Gaps: formalized supply-chain management, board-level accountability, sector-specific incident notification timelines. Matproof's NIS2 module layers on top of ISO 27001 evidence without duplicating work.
