ISO/IEC 27001
Information Security Management System
ISMS Certification
ISO/IEC 27001 is the internationally recognized standard for information security. Certification builds trust with enterprise customers, unlocks tenders, and provides solid evidence for NIS2 and GDPR. THE BARK guides you from scope to certificate.
More and more enterprise customers, tenders, and supply chains require an ISO 27001 certificate as a prerequisite. Those who start the build early secure contracts that would otherwise go to the competition.

Who benefits from ISO 27001?
ISO 27001 is not a legal obligation but a strategic advantage. Certification is especially relevant for companies that must demonstrate trust and stay competitive in the market.

- Data processors (GDPR)
- Handlers of sensitive data
- NIS2-affected entities
- Public-sector vendors
- Finance & healthcare sector
Note on applicability: ISO 27001 is a voluntary standard – there is no legal obligation to certify. In practice, however, it is increasingly required contractually: by enterprise customers, in public tenders, and as recognized evidence in the context of NIS2 and GDPR. Companies of any size can become certified.
What does ISO 27001 specifically require?
The standard defines a continuous management process (PDCA) as well as binding controls. These six building blocks form the foundation of an audit-ready ISMS.
ISMS scope & context
Definition of scope, internal and external issues, and relevant interested parties. The ISMS must be clearly delimited and tailored to the organization.
Risk assessment & treatment
Systematic identification, analysis, and evaluation of information security risks. A documented treatment decision is made for each risk.
Statement of Applicability (SoA)
The central applicability statement: which of the 93 Annex A controls are relevant, which are implemented – and which are excluded with justification.
Annex A controls implementation
Implementation of the selected measures across four themes: organizational, people, physical, and technological.
Internal audit
Regular internal audits verify that the ISMS is effective and conforms to the standard. Nonconformities are documented and corrected.
Management review & improvement
Top management regularly reviews the ISMS. Findings feed into continual improvement – the core of the PDCA cycle.
The path to certification
A typical ISO 27001 certification journey – from kickoff to certificate.
Project start & scope
Definition of scope, assembly of the team, and assignment of responsibilities. The foundation of the ISMS is laid.
Gap analysis & risk register
Comparison of the current state against ISO/IEC 27001:2022 and creation of a complete risk register with treatment plan.
Controls & documentation
Creation of policies, implementation of Annex A controls, and build-up of the audit-ready ISMS documentation including the SoA.
Where we step inStage 1 & 2 audit
An external certification body reviews the documentation (Stage 1) and effectiveness (Stage 2). On success: a certificate valid for 3 years.
