ISO/IEC 27001 is an international standard that defines the requirements for implementing an Information Security Management System (ISMS). It guarantees the confidentiality, integrity and availability of your organization’s data.
The timeframe depends on the size of the organization, its maturity and the complexity of the information system. On average, a well-managed project takes between 6 and 12 months from initial audit to certification.
No. ISO 27001 is suitable for all sizes of company, including SMEs, startups and associations, as long as they handle sensitive data or wish to demonstrate their commitment to security.
An ISMS includes:
The standard does not formally require this, but recommends clarifying roles and responsibilities. It is therefore highly advisable to appoint an information security manager, whether in-house or outsourced.
Yes, and it’s even recommended. Support from ISO 27001-certified experts like those at Netsystem helps to structure the project, avoid common mistakes and save time on the road to certification.
Certification is valid for 3 years, with surveillance audits every year. It is therefore essential to keep your ISMS up to date, and to pursue continuous improvement actions.
ISO 27001 is the certification standard that defines the requirements. ISO 27002 is a best practice guide detailing the security measures to be applied. They are complementary.
“Accompanying Docoon in obtaining its ISO 27001 certification was a demanding, stimulating project, perfectly aligned with our approach: pragmatism, proximity and operational excellence. Right from the initial audit phases, we built up a relationship of trust with the in-house teams, which enabled us to rapidly structure a robust ISMS, adapted to the challenges of the sector, while ensuring an increase in the skills of all stakeholders. The commitment of the Docoon teams, coupled with our step-by-step support methodology, enabled us to achieve our objective in less than 10 months, with certification obtained right from the first audit. It's a source of shared pride, and a fine example of a project where compliance becomes a real lever for credibility and performance.”

ISO 27001 is much more than a security standard: it's a true governance framework that transforms the way an organization protects its most critical assets. At Netsystem, we have designed our support offer to be rigorous, structured... and pragmatic. Each customer starts from a different level of maturity: our role is to lead them towards certification by helping them build an Information Security Management System (ISMS) tailored to their culture and challenges. We intervene throughout the entire cycle: initial audit, definition of the action plan, implementation, preparation for the certification audit and post-certification support. And always with a view to transferring skills. We take pride in the fact that our customers not only emerge certified, but above all better prepared to manage cyber risks, meet regulatory obligations and win the trust of their partners.
