Cybersecurity Expert Modern Workplace

Project overview

Context

We are looking for confirmed expertise in cybersecurity to strengthen the security of all components related to the end-user environment, particularly IT workstations, Microsoft 365, and ITSM services. We wish to benefit from support capable of defining, maintaining, and improving the security posture of the Modern Workplace perimeter, in close coordination with Cybersecurity teams, SLS, cloud teams, M-CISOs, and our outsourcing partners.

The expected expertise includes ISO 27001 governance, control monitoring, risk analysis, technical audits, and remediation plan management. It also involves structuring and managing a third-party assurance framework, including security indicator monitoring, representing the company in supplier committees, and continuous improvement of delivered services.

This expertise will contribute to cybersecurity incident management, the definition of standards and guidelines, and their communication to local operational teams and SLS. Finally, it will participate in architecture committees, Group transversal projects, the organization of penetration tests and technical audits before production deployment, as well as the production of dashboards for management.
