Security & GDPR
GDPR and data: a practical guide for leadership
What the GDPR requires when exploiting data, what responsibility falls on leadership and how to work with sensitive data without losing control or compliance.
Read articleKey takeaways
- ISO/IEC 27001 is the international standard for managing information security.
- It is based on risk management and continuous improvement, not fixed controls.
- Certification provides verifiable trust to customers and partners.
- It complements GDPR compliance.
- Working with certified providers reduces whole-chain risk.
Information security is not demonstrated with good intentions or a sales pitch, but with a verifiable system. ISO/IEC 27001 is the international reference standard for structuring that security so an independent third party can audit and certify it.
What it is
ISO/IEC 27001 is the international standard for information security management systems (ISMS): it defines how to identify risks, apply controls and continuously improve information protection.
What it involves
The standard does not impose fixed controls but a method: identify risks to information, decide which controls to apply and review the system continuously. It includes a reference control annex covering access, encryption, physical security, incident management and more.

Why it builds trust
- Verifiable: certification is audited by an independent third party.
- Comprehensive: covers people, processes and technology.
- Recognised: a globally accepted international standard.
- Continuous: it requires review and improvement.
Relation to the GDPR
ISO 27001 and the GDPR are not the same, but they reinforce each other. The GDPR requires appropriate security measures (Art. 32); an ISMS compliant with ISO 27001 is one of the best ways to demonstrate they exist and are managed. Working with providers that follow these standards reduces the whole chain’s risk.
ISO 27001 turns security from "trust us" into "an independent third party has audited it".
In summary
ISO/IEC 27001 is the international standard for managing information security through a risk-based, continuously improving system. Its value is being verifiable: a third party certifies that security is taken seriously. It complements the GDPR, and choosing certified providers reduces whole-chain risk.

Frequently asked questions
Is ISO 27001 mandatory?
Not by law, but it is the reference standard for demonstrating serious information-security management and is often required in B2B contracts.
Does ISO 27001 cover the GDPR?
It does not replace it, but reinforces it: it helps demonstrate the appropriate security measures the GDPR requires.
What does certification provide?
Verifiable trust: an independent third party audits that security is managed to the standard, rather than relying on the provider’s word.
Does it impose specific controls?
Not a fixed list. It defines a risk-based method and includes a reference control annex; each organisation applies what its risk analysis justifies.
Is it a one-off effort?
No. It requires continuous improvement with periodic reviews and follow-up audits. Certification is maintained, not obtained once and forgotten.
Why does a certified provider matter?
Because your data security depends on your supply chain too. An ISO 27001-certified provider passes on those guarantees verifiably.
