Win 1 year's access to Information Security E-Learning at our 50th Cyberzone(register)
This guide is aimed at CEOs, CTOs and technical managers who wish to initiate an ISO 27001 certification process, but lack the guidance they need to choose the right service provider.
At FeelAgile, we have supported numerous companies in this type of project. Many have also approached us after a difficult first attempt, often linked to poor support or a partial understanding of the standard's requirements.
We have therefore structured this guide around two objectives: to explain what makes an ISO 27001 project a success, and to identify the key elements for choosing the right support.
The ISO 27001 standard has become a reference standard for companies wishing to structure their information security management.
It requires the implementation of an ISMS (Information Security Management System), i.e. a set of security processes, policies and measures covering technical, organizational and regulatory aspects.
Today, this certification is a real lever of commercial credibility, particularly in calls for tender or relations with demanding principals.
In 2025, it is seen as a prerequisite in many sectors, with a direct impact on commercial growth, corporate image and the ability to structure processes.
The ROI of ISO 27001 :
Watch our CEO, Thomas de Mota, explain why ISO 27001 is a must-have for information security.
Choosing a service provider forISO 27001 support is more than just a one-off assistance: it's a strategic decision that involves the entire certification project.
Attempting to carry out such an approach on your own means navigating a dense and complex standards environment, combining the requirements ofISO 27001, related regulations such as the RGPD or the NIS 2 directive, and technical and organizational constraints.
For an SME, a project that is poorly framed or poorly supported can lead to :
An experienced service provider provides multidisciplinary expertise, covering :
It also draws on real-life feedback, helping toavoid critical errors and ensure long-term compliance.
In addition to our expertise, we provide personalized advice and proven, directly applicable solutions to meet the requirements of the standard.
This partnership makes it possible to build a maintainable ISMS, i.e. a security system :
In short, the right support transforms a complex, high-risk project into a structured, managed and controlled process, geared towards the continuous improvement of information security. This is also the key to achieving ISO 27001 certification.
It's essential to understand that ISO 27001 isn't just about writing documents to tick boxes.
It is the implementation of an Information Security System that involves three key elements:
Companies that fail or run into difficulties are often those that underestimate this structural dimension. Understanding the spirit of the standard is a prerequisite for any certification process.
A poorly designed ISMS is like a poorly organized company - it doesn't necessarily have a happy ending.
It's a question that needs to be asked right from the start of the project. Obtaining a certificate is not enough: success is measured on several levels.
Successful ISO 27001 certification means :
To succeed, it's also essential to define your objectives in advance, distinguishing between the expected results (certification, compliance, risk reduction) and the method of implementation (timeframe, resources mobilized, method).
Last but not least, solid certification rests on four critical pillars:
👉 To better understand what differentiates a formally certified project from a truly successful one, we invite you to view our video resources: The worst mistakes in ISO 27001 certifications.
Before committing to ISO 27001 support, it's essential to know exactly what your level of maturity is in terms of information security and compliance. The success of the project depends on this scoping stage.
Two approaches are possible at this stage:
This analysis also helps to define the fundamental elements for framing the project:
Involving an expert in this initial phase ensures that you get off to the right start, avoid framing errors, and build a support package that's truly tailored to your needs.
The success of a project depends on rigorous management: a structured schedule, clear milestones and monitoring indicators. A good service provider not only provides documentation and technical expertise, but also acts as project manager, guaranteeing progress and overall consistency.
Training is often overpriced or poorly targeted. Some companies mobilize their teams massively on highly theoretical ISO 27001 training courses, sometimes disconnected from reality in the field. The challenge is to provide teams with the keys to understanding their role in the project, without overwhelming them. Well-designed e-learning formats, accessible on demand, are often more effective than a catalog of classroom sessions. Take a look at our ISO 27001 e-learning!
The service provider's experience with concrete certification projects is a decisive criterion. Good command of the standard is not enough. They must also know how to adapt the requirements to the reality of internal processes, propose a structured method, and support the production of deliverables (risk analysis, safety policies, indicators, etc.).
A mock audit or end-of-project document review is used to check the conformity of the ISMS before the official audit. It's not just a question of simulating an audit, but of carrying out a methodical review, supported by checklists, to identify areas of fragility and secure the outcome of the process.
Certification support does not stop at preparing for the big day. The service provider must also help you choose a suitable certification body, put together the certification file, and prepare for the interviews. This final phase is a strategic one: it determines whether or not you obtain certification, and whether or not surveillance audits are carried out in the years that follow.
Successful ISO 27001 certification is as much about method as it is about substance. Choosing the right service provider for your ISO 27001 support guarantees that your project will be structured, controlled and maintainable. It also means ensuring that your company makes real progress in its security maturity, over and above obtaining a certificate.
In the second part of this guide, we analyze the different types of service providers, their profiles, and the concrete criteria for making the right choice according to your sector and level of maturity.
