ZSD Specializes in setting up and supporting systems based on Debian Linux Servers.
We use Debian Linux as our tool. It is stable, secure, flexible, runs on modest hardware and has modest electricity consumption. No licence fees are payable, hence lower costs to our customers. It is Open Source and free from political and business interference from corporate licence holders.
We provide solutions for our customers with initial installation and ongoing support.
We support remotely and telephonically, wherever our customers are located. Our office hours share European time zones and our staff speak English as their first language.
Our customers do not need any Linux specific knowledge.
We have been using Debian Linux for over 20 years. We have over 200 servers under active support. Some of these installations have been in service for many years (with regular software and occasional hardware upgrades).
