For more than 18 years, Tranquil IT has been helping her customers to better operate their local networks with the aim of making their users more efficient and happy. Our missions are structured around 2 main areas of work: (1) WAPT fleet management software (apt-get for Windows). WAPT is designed to help fleet managers deploy, update and remove applications and configurations on their Windows, Linux and macOS fleets (see https://wapt.tranquil.it/) (2) Samba-AD; TIS is the first Samba-AD integrator in Europe and a well known specialist on all things Active Directory (https://samba.tranquil.it) Our vision is that the combining the two methods highly simplifies and secures the management of users, devices and applications. In short, Tranquil IT is a condensed version of DevOps and Cybersecurity, simple! Tranquil IT works closely with the cyberdefense bodies of the French State.
