We are PASSI qualified!

Since November 2020, we are Prestataire d'Audit de la Sécurité des Systèmes d'Information (PASSI). This French qualification, delivered by ANSSI, confirms our audit expertise as well as the care with which we ensure the confidentiality of our clients' data. This qualification also confirms our respect of the ISO 19011 audit procedure. We are qualified on pentests, configuration audits, architecture audits, as well as organisational and physical audits.

We are ISO 27001:2022 certified!

In addition to our PASSI qualification, we have chosen to obtain ISO 27001 certification for the perimeter of our infrastructure from which we conduct our PASSI audits. On the one hand, this certification allows us to raise our security level even higher, not only from a technical point of view, but also and especially from an organizational and process management point of view. On the other hand, it demonstrates that we apply to ourselves the advice we give to our customers. Obtaining this certification is the result of several months of work, but it is worth the effort to enable us to better protect the sensitive data we may be handling.
