The management team is led by Thierry Bardy.
Capital Croissance supports the Group in the acceleration of its development in France and abroad, and in the ramp-up of its latest offerings and the development of Custocy.

Created in 1997 in Castres in the context of the opening of telecoms to competition, IMS Networks was the first local company in France to design, deploy and operate a very high-speed optical fibre network. Today, IMS Networks assists its 350 customers in France and abroad with their network issues (choice of infrastructure, site interconnection, network outsourcing, etc.) but also with their cybersecurity challenges.


More recently, the Group has expanded its range of services in the field of cybersecurity with the launch of a cybersecurity audit and consulting activity through its subsidiary Cyblex Consulting. It is also developing Custocy, a Network Detection & Response solution that enables real-time 3D visualization and detection of cyberattacks on its customers’ networks.

Muriel Bouyssière (CFO of IMS Networks): “With Thierry Bardy, President of the Group, we are very pleased to be associated with Capital Croissance, whose entrepreneurial DNA, expertise and active support made the difference in the process led by Adviso Partners. Their support, as well as that of our other shareholders, will help us to accelerate our development in France and abroad.”
