Our history


    In order to enjoy his well-deserved retirement, Bernard Dufrêne is selling Tenotel to Rcarré, a Luxembourg company that has been active for more than 20 years and specialises in IT networks, cloud, unified communications, security, technical resources and governance.

    This acquisition is being made in a smooth and benevolent manner towards the company's staff and Tenotel's customers.

  • 2020 - LA RELÈVE

    Nowadays, we continue to develop our range of services

    Guillaume and Laetitia, Bernard's children, are taking over gently to ensure the continuity of the family business. At the same time, this brings a new and dynamic outlook to the world of telecoms while retaining Tenotel's experience and expertise.

  • 2016 - Network and security

    Following the convergence of telephony and IT, in June 2016 Tenotel strengthened its "networks and security" service in order to be able to offer its customers a panel of skills at all levels. In addition to network management and monitoring, priority is given to security, which is essential in today's world.

  • 2013 - Acquisition

    In September 2013, when the opportunity appeared to take over Telecom Luxembourg's traditional telephony business, Tenotel naturally seized the opportunity to strengthen its presence on the market in order to ensure its growth. In order to ensure a seamless transition for customers, Tenotel took over not only the maintenance and rental contracts but also the entire team providing these services.

  • 2008 - VOIP

    Bernard has offered his services in the traditional telephony sector. Very quickly telephony changed and he adapted to provide VoIP solutions.

  • 2007 - Création

    After more than 25 years of experience in the sector, Bernard Dufrêne decided to have his own company and created Tenotel in September 2007.
