Netsystem is PASSI qualified

The PASSI qualification is issued by the Agence Nationale de Sécurité des Systèmes d’Information (ANSSI).

It is aimed at trusted service providers who carry out organisational and physical security audits, as well as audits of technical scopes, on their own behalf or on behalf of their customers.

It is a real guarantee of quality and expertise for organisations looking for a cybersecurity consultancy to carry out an audit of their structure.

Call on a service provider officially recognised by the Agence nationale de la sécurité des systèmes d’information (French national agency for information systems security) to assess, improve the reliability and strengthen the security of your information system.

Why carry out a PASSI cybersecurity audit?

Why carry out a PASSI audit?

Strengthen your security posture with a certified audit

PASSI audits are essential for:

  • Meeting security obligations (NIS2, OIV/OSE, sensitive projects…)
  • Identifying organisational or technical vulnerabilities
  • Evaluating the compliance of your IS architecture
  • Preparing for certification (ISO 27001, SecNumCloud, etc.)
  • Securing your critical projects (cloud, infrastructure, etc.)
How long does a PASSI audit last?

The duration of a PASSI audit varies according to the scope and complexity of the system being audited. On average, a full PASSI audit (organisation or architecture) takes between 5 and 15 days, including the scoping, analysis and reporting phase.

Is a PASSI audit compulsory?

A PASSI audit is mandatory for certain sensitive players such as OIVs (Opérateurs d’Importance Vitale) or OSEs (Opérateurs de Services Essentiels). It may also be required as part of NIS2 compliance or for projects such as SecNumCloud.

What are the deliverables of a PASSI audit?

At the end of a PASSI audit, you receive a full report containing:

  • detailed findings (strengths and vulnerabilities)
  • a compliance analysis
  • a prioritised action plan
  • concrete recommendations tailored to your context
Can I use the PASSI audit to support ISO or SecNumCloud certification?

Absolutely. The PASSI audit can complement an ISO 27001, SecNumCloud or TISAX certification process. It provides an independent, qualified assessment of your security posture.
