Until now, our employees have been using very common 'general public' tools such as instant messaging applications and our objective is to change this, switching them to a more secure tool. Citadel Team is part of that logic. I am happy to contribute to its deployment within CNES.
Reputation management of an executive clientele requires the use of perfectly secure tools. For the validation of contents and confidential documents, we prefer Citadel Team, the French solution of excellence.
