NSE is certified in the activities of Maintenance (level 1), Preparation, Storage, Logistics and Distribution. An official body is responsible for auditing certified activities based on a set of requirements. By working with a Remparts certified company, the client no longer has to worry about auditing the service provider themselves. Working with NSE means ensuring that security processes are ensured from end to end, whether physical security (alarm, access control, cameras, etc.), logical security (firewall, controlled IT rights, etc.) or business security. This certification confirms NSE's ambition to structure its organization with the aim of continually improving the level of services provided to its customers.
