We are using the Debian operating system on more than 100 servers, for our internal servers (homemade applications and virtualization), and also for external web servers as our corporate website and our eLearning system, https://www.formation-cybersecurite.com/. Debian is definitely easy to upgrade and manage, it has lot of available packets. We like it :)
As an IT security company, AKAOMA is considering security as a major priority. Having a huge and active community, Debian is thus the operating system we recommend to our customers.
