Become an auditor

Become a key player in digital confidence by conducting audits for ISO 27001, ISO 27701 certification and ANSSI qualification (PASSI, SecNumCloud...). We're looking for independent, certified experts with a passion for compliance and information systems security. Join our ecosystem of excellence and make the most of your technical expertise!

Become an external LSTI auditor and contribute to demanding assessments in our three areas of expertise: cybersecurity, digital trust and information security. You will be involved in certification assignments for companies, services and management systems, using recognised standards and proven audit methodologies.

 

Your proven experience in information systems, your mastery of cybersecurity issues and your structured analytical skills are essential levers for producing impartial, high-value-added assessments.
By joining the LSTI family of auditors, you will become part of a network of experts committed to quality and rigour. LSTI provides you with a professional, organised and collaborative environment based on strong values: integrity, impartiality, high standards and trust. You will exercise your expertise independently, while benefiting from the support of a recognised organisation.
