To strengthen the security of its IT infrastructure, the SIAAP wanted to equip itself with a solution that would address two main issues: controlling access to external service providers and securing access to SCADA monitoring.Both managing the access of external service providers to the VPN and opening the rules teams were becoming a major workload for the IT teams. In addition, Stéphane Corblin wanted the functional managers of the applications to be aware of the operations performed by their service providers.It was also necessary to ensure access to SCADA monitoring for certain agents, especially during on-call service. Since the latter are connected via RDP to a station located between the IT and industrial firewalls, better visibility was essential. The SIAAP also had to replace the servers located in the exchange areas that did not necessarily meet the security standards to be applied.The Paris Sanitation Authority wanted to implement a solution that was quick to deploy, easy to administer and had French-speaking support available.
