ISO 27001: the trusted standard for information security.
A structured approach to protecting corporate information.
The ISO/IEC 27001 Standard
ISO 27001 is the leading international standard for information security, designed to support organizations of any size or industry in adopting an Information Security Management System (ISMS), ensuring a structured and effective approach to data protection.
It serves as a key tool for designing a comprehensive and effective corporate security plan. Today, ISO 27001 is recognized as one of the most thorough standards, consisting of carefully selected guidelines and controls. It goes beyond IT security, encompassing physical/environmental and organizational security as well.
ISO 27001 safeguards the core aspects of information security, summarized in the three pillars of cybersecurity:
Confidentiality
Ensures that data is accessible only to authorized individuals, preventing unauthorized access.
Integrity
Ensures that information is accurate, complete, and unaltered without authorization, preserving its reliability.
Available on
Ensures access to data and systems when needed, preventing disruptions or data loss.
How ISO/IEC 27001 certification works
ISO/IEC 27001:2022 certifies that an organization manages information security through a risk-based Information Security Management System (ISMS). The standard has two parts: the mandatory management clauses (4-10) and Annex A, the catalogue of security controls to be selected based on risk.
The mandatory clauses (4-10)
They define how the ISMS is built and maintained. They are requirements, not options.
- Context of the organization and scope definition
- Leadership and management commitment
- Planning and risk assessment
- Support: resources, competence, documentation
- Operations and risk treatment
- Performance evaluation and internal audits
- Improvement and management of nonconformities
Annex A: 93 controls across 4 themes
The 2022 revision reorganized the controls from 114 to 93, grouped into four themes and with 11 new controls (including threat intelligence, cloud security, and data masking).
- A.5 - Organizational controls (37)
- A.6 - People controls (8)
- A.7 - Physical controls (14)
- A.8 - Technological controls (34)
The applicable controls are documented in the Statement of Applicability (SoA), the cornerstone document of the certification.
The certification path in five stages
Gap analysis
Defining the ISMS scope and comparing it against the standard's requirements.
Implementation
Policies, risk assessment, treatment plan, and Statement of Applicability.
Internal audit
Internal verification and management review before the certification body.
Certification audit
Stage 1 (documentation) and Stage 2 (control effectiveness), conducted by an accredited body.
Surveillance
Annual surveillance audits and full recertification every three years.
ISO 27001, NIS2, and GDPR: how they fit together
An ISO 27001 ISMS does not replace regulatory obligations; it provides the risk-management structure that NIS2 and GDPR require - and produces reusable evidence. Most NIS2 baseline measures and the security-of-processing principle (GDPR Art. 32) are already addressed by Annex A controls.
In Italy, the UNI/PdR 174:2025 reference practice explicitly links ISO/IEC 27001 to NIS requirements, letting already-certified organizations build on the work they have done.
ISO/IEC 27001 certification is not mandatory - so why get certified?
The main information-security regulations and standards — such as the NIS 2 Directive and the ISO/IEC 27000 family — provide an essential framework to ensure operational continuity, protect sensitive data, and manage cyber risks. Within the European landscape, the DORA regulation for the financial sector also helps shape the regulatory context, although it is not currently part of Aegister's service offering. Implementing an ISMS in accordance with ISO/IEC 27001 requires significant commitment, but the benefits are substantial.

Frequently asked questions about ISO 27001
ISO/IEC 27001 is the international standard that certifies an Information Security Management System (ISMS). Certification attests that the organization manages information security with a systematic, risk-based approach, validated by an accredited certification body.
For most organizations the path takes 6 to 12 months, depending on size, number of sites, and the maturity of existing controls. After implementation, the Stage 1 (documentation) and Stage 2 (control effectiveness) certification audits take place.
The cost depends on the ISMS scope, the organization's size, and the number of sites, and consists of the implementation effort plus the certification body's fee. Aegister starts with an assessment to define scope and gaps and provide a realistic estimate.
ISO 27001 is the certifiable standard: it contains the ISMS requirements and Annex A with its 93 controls. ISO 27002 is the implementation guidance that explains in detail how to apply each control, but it is not certifiable.
No, ISO 27001 is not mandatory. However, a certified ISMS covers most NIS2 baseline measures and the security-of-processing principle (GDPR Art. 32), producing reusable evidence. In Italy, the UNI/PdR 174:2025 practice explicitly links ISO/IEC 27001 to NIS requirements.
