At a Glance

What Is ISO 27001?

ISO/IEC 27001 is the world's leading standard for information security management systems (ISMS). It defines how companies systematically manage, monitor and continually improve information security.

The current version ISO 27001:2022 introduces 93 controls across 4 themes (instead of 114 in 14 categories) and new focus areas such as cloud security, threat intelligence and data masking.

ISO 27001 is the foundation for all other standards – TISAX, CADIS, NIS2 and IEC 62443 build upon it or reference it directly.

🏆 CONSUVATION – Pioneers Since BS 7799

Our consultants were among the first certified BS 7799 auditors in Germany – the direct precursor to ISO 27001. This foundational expertise combined with current practice makes us one of the most experienced ISO 27001 consulting firms in the DACH region.

ISO 27001:2022 – Annex A

ISO 27001 & Other Standards

How ISO 27001 Relates to Other Standards

ISO 27001 is the foundation – all other relevant standards build upon it or reference it directly. Companies that already have ISO 27001 have completed most of the work.

ISO 27001 → TISAX ISA

TISAX is based directly on ISO 27001 Annex A. Companies that already have ISO 27001 reach TISAX with significantly less effort. TISAX ISA now also covers OT availability of production facilities.

AutomotiveVDAOT

ISO 27001 → IEC 62443

IEC 62443 specialises ISO 27001 for industrial control systems (OT). Implemented together, they create a complete ISMS with technical OT depth for SCADA, PLCs and DCS.

OT SecuritySCADAIndustry

ISO 27001 → CADIS

CADIS Module 1 is based entirely on ISO 27001. Companies certified to ISO 27001 have already fulfilled the most important CADIS module. CONSUVATION guides you through both standards in a single project.

DefenceDEKRA14 Modules

ISO 27001 → NIS2

NIS2 requires appropriate cybersecurity measures – without prescribing specific tools. ISO 27001 is the internationally recognised evidence of NIS2 compliance and is considered "best practice".

NIS2Critical InfrastructureBSI

ISO 27001 → GDPR

ISO 27001 directly addresses the technical and organisational measures required under Art. 32 GDPR. An ISO 27001 ISMS provides evidence of appropriate data security to supervisory authorities.

GDPRArt. 32TOMs

ISO 27001 → BSI IT-Grundschutz

BSI IT-Grundschutz and ISO 27001 are aligned with one another. Many authorities and critical infrastructure operators combine both frameworks. CONSUVATION is familiar with both approaches and integrates them efficiently.

BSICritical InfrastructureAuthorities

ISO 27001 → ISO 27005

ISO 27001 requires a risk assessment but does not prescribe a methodology. ISO 27005 provides exactly that – tailored specifically to information security and, in its current 2022 edition, closely aligned with the terminology and risk framework of ISO 31000. It is the methodological link between the ISMS requirement and generic risk management.

Frequently Asked Questions

ISO 27001 – Frequently Asked Questions

What is ISO 27001?
ISO/IEC 27001 is the international standard for information security management systems (ISMS). It defines requirements for establishing, implementing, operating and continually improving an ISMS – and is the foundation for TISAX, CADIS, NIS2 and many other standards.
What changed with ISO 27001:2022?
The new version introduces 93 instead of 114 controls, structured into 4 instead of 14 categories. 11 new controls were added – including threat intelligence, cloud security, data masking and secure coding. Existing certifications had to transition by October 2025.
How long does ISO 27001 certification take?
Depending on company size and starting point, typically 6 to 18 months. With an experienced consultant and CONSUVATION's structured approach, this timeframe can be significantly shortened – especially if related standards (TISAX, NIS2) have already been implemented.
What is the relationship between ISO 27001 and NIS2?
NIS2 requires appropriate cybersecurity measures but does not prescribe specific tools. ISO 27001 is the internationally recognised "best practice" evidence for NIS2 compliance. Companies with ISO 27001 can demonstrate NIS2 requirements very efficiently.
What is the difference between ISO 27001 and IEC 62443?
ISO 27001 addresses overall information security. IEC 62443 specialises in industrial control systems (OT – SCADA, PLCs, DCS). Both complement each other: ISO 27001 as the ISMS foundation, IEC 62443 for OT depth. CONSUVATION implements both standards in one integrated project.
Do I have to get ISO 27001 certified?
Certification is not legally mandatory – but is often required by customers, OEMs or authorities. NIS2 and TISAX don't require formal ISO 27001 certification but recommend following the ISO 27001 approach. CADIS explicitly requires an ISMS according to ISO 27001.
What methodology should I use for the ISO 27001 risk assessment?
ISO 27001 requires a risk assessment but does not prescribe a specific methodology. ISO 27005 provides the risk management process tailored specifically to information security and, in its current 2022 edition, is closely aligned with the generic risk framework of ISO 31000. CONSUVATION implements this methodology in a structured way within your ISMS.
