The ISO 27001 certification guide: how to obtain it and successfully manage your compliance?

The path to certification is often perceived as an exhausting administrative marathon. Between risk analysis, policy drafting, and evidence gathering for the audit, how can you avoid getting lost? How can you obtain ISO 27001 certification in France in a structured and efficient manner?

We review the key steps, best practices for implementation, and tools to transform your compliance project into a sustainable strategic advantage!

How to obtain ISO 27001 certification in France?

In France, the certification process follows a rigorous procedure supervised by accredited bodies (such as AFNOR or LSTI). It is not just a simple exam, but a continuous improvement process that proves that your company proactively protects its data.

The 4 essential steps of the compliance project

To achieve ISO 27001 compliance, you must structure your approach around four pillars.

1. Risk diagnosis and analysis: this is the mandatory starting point. You must identify your assets (data, servers, know-how) and assess the threats to them. This is where you define your certification scope.
2. Implementation of the ISMS: you deploy the security measures (technical and organizational) identified during the analysis. This includes drafting the Information Systems Security Policy (ISSP) and raising awareness among employees.
3. Internal audit (dry run): Before the final audit, you must verify that your ISMS is operational. This step allows you to correct any non-conformities before the external auditor arrives.
4. Certification audit: conducted by an independent third party, this audit takes place in two stages (document review followed by on-site verification). If successful, your certification is issued for a period of three years, with annual surveillance audits.

How to choose a provider for ISO 27001 certification?

To obtain certification, you must use a certification body accredited by COFRAC (French Accreditation Committee). You should also ensure that the service provider has specific expertise in your sector of activity to ensure a relevant assessment of your business risks.

What software solutions help with ISO 27001 compliance management?

Given the complexity of the standard, the days of managing it using Excel spreadsheets are over. To keep an ISMS alive and effective, the use of a GRC (Governance, Risk & Compliance) platform has become the norm. Dedicated software does more than just store your documents: it structures your approach.

• Centralization of the repository: all ISO 27001 requirements are preloaded and translated into concrete actions.
• Real-time dashboards: instantly view your maturity level and any remaining risk areas that need to be addressed.
• Simplified collaboration: you assign tasks to the various managers (HR, IT, Legal) and track overall progress without endless follow-ups.

What are the best tools for conducting an ISO 27001 audit?

The success of your audit depends on your ability to provide irrefutable evidence to the auditor. The best tools for preparing for this deadline are those that automate data collection.

Rather than manually collecting screenshots, Tenacy connects to your technical ecosystem (EDR, Cloud, IAM) to automatically report evidence of compliance. During the audit, you no longer have to search for information: it is already there, documented and archived.

Why choose Tenacy for your ISO 27001 certification?

FAQ – Everything you need to know about ISO 27001 certification

What is the cost of ISO 27001 certification?

The cost varies depending on the size of the company and the complexity of the scope. You need to factor in the fees charged by the certifying body (audit), the internal time allocated to the project, and possibly the support of a consultant or investment in a compliance management tool. In the long term, automation drastically reduces the costs of maintaining certification.

How long does it take to obtain ISO 27001 certification?

On average, a certification project lasts between 6 and 18 months. This timeframe depends on your initial maturity in cybersecurity and the resources mobilized. Using a platform such as Tenacy often speeds up the structuring and evidence collection phase.

What is the difference between ISO 27001 and ISO 27002?

ISO 27001 defines the requirements for implementing ISMS (the management framework).ISO 27002 is a collection of best practices that details how to implement the security measures (controls) listed in Annex A of ISO 27001.

Conclusion: Don't just endure compliance, manage it!

Obtaining ISO 27001 certification is a major milestone that validates the strength of your cybersecurity strategy. But the real challenge begins after the audit: implementing your ISMS on a daily basis without weighing down your operational processes.

By centralizing your risks, your reference systems, and your technical evidence, Tenacy transforms an administrative constraint into a true strategic dashboard.
