What is it?
The PACS standard (Prestataire d'Accompagnement et de Conseil en Sécurité des Systèmes d'Information) is a qualification issued by ANSSI (Agence Nationale de la Sécurité des Systèmes d'Information). Its purpose is to attest to the competence, impartiality and reliability of service providers offering cybersecurity consulting and support services. A PACS-qualified service provider demonstrates its ability to deliver top-quality services, in compliance with a rigorous ethical and methodological framework, particularly in the fields of security certification, risk management, architecture security and cyber crisis management preparedness. This qualification is a guarantee of confidence for our clients, in particular OIVs (Opérateurs d'Importance Vitale) and OSEs (Opérateurs de Services Essentiels), but also for any company concerned about the protection of its sensitive information.
The challenges of PACS certification


Calling on an LSTI Certification-qualified PACS service provider provides fundamental guarantees for your cybersecurity projects:
- Trusted expertise: the assurance of working with consultants whose skills are officially recognized and validated by ANSSI.
- Security and quality of services: Guaranteed high quality of deliverables and methods, based on PACS requirements.
- Risk reduction: Better control of cyber risks thanks to expert support in IS security risk management.
- Regulatory compliance: Invaluable help in obtaining security certification for your information systems, simplifying the process of achieving compliance.
- Architectural reinforcement: Obtain relevant advice to secure your IS architectures in the face of current threats.
- Crisis preparedness: Improve your organization's ability to anticipate and effectively manage a cyber incident or crisis.
How does PACS certification work?
This qualification follows an audit of your organization, your business processes and your information systems, and verification of your consultants' skills. LSTI carries out the audit and competency testing.
The service provider can choose to be qualified for all or some of the scopes covered by the PACS standard. However, it is not possible to qualify only for the Homologation de sécurité des systèmes d'information scope.
PACS qualification attests to a company's skills and the quality of the support services it provides to its customers.
Qualification is issued by ANSSI for a period of three years, with a surveillance audit after 18 months and a renewal audit in the third year.
As certain requirements of the PACS standard are common to PASSI, ANSSI has set up a gateway system for PASSI-qualified companies wishing to become PACS-qualified.
