Linux Managed Services
We operate Linux and Proxmox servers, OPNsense firewalls and other open source systems. You choose one of three service levels: Basic, Plus or Premium.

The problem
Building a Proxmox VE cluster takes days. Running it takes hours every week, for years. Security updates keep arriving. Certificates expire. Disks fail. A firewall rule suddenly blocks a service, and the alert goes to a mailbox nobody reads.
In small IT teams this operational knowledge often sits with one person. When that person is on holiday, updates wait. When they leave, the knowledge leaves with them.
What inett does
We operate your Linux and Proxmox servers, your OPNsense firewalls and other Linux and open source systems. inett is a Proxmox Gold Partner.
You commission the service from us, inett SARL, and we are your point of contact. Operations are carried out by inett GmbH, our sister company in Germany, as our partner. The two companies are legally independent.
The systems can run in two places:
- in the SAAR1 data centre in Saarwellingen (Germany), if you would rather not run your own infrastructure. inett SARL rents resources there from inett GmbH.
- in your own data centre, if the systems should stay on your premises
Our work covers three tasks:
- Monitoring: we watch your systems and spot faults before your users report them.
- Updates: we apply security and feature updates, for example to Linux, Proxmox VE, Proxmox Backup Server and OPNsense.
- Troubleshooting: when monitoring flags a problem, we find the cause and fix it.
How far each task goes depends on the service level you choose.
Three service levels
The higher the level, the tighter the SLA. Premium gets a faster guaranteed response than Plus, and Plus a faster one than Basic.
| Basic | Plus | Premium | |
|---|---|---|---|
| Guaranteed response time | longest of the three | shorter than Basic | shortest of the three |
We state the exact response and service times and the scope of each level in our quotation.

Who this is for
Managed services suit organisations that run Linux servers, a Proxmox VE cluster or an OPNsense firewall and want to take load off their IT team. Typical clients are SMEs, public sector bodies and IT service providers in Luxembourg and the Benelux region.
They are not a fit if your servers run mainly on Windows: our focus is Linux and open source. Nor are they the right choice for a one-off project. Consulting covers that better.
If you need on-call cover outside our office hours, this is available through inett GmbH. We agree the details with you in the quotation.
Frequently asked questions
Do our servers have to move to your data centre?
No. We look after systems in the SAAR1 data centre and in your own. You decide.
Which service level do we need?
That depends on how long your systems can be down. The shorter that window, the higher the level should be. We work this out with you in a first meeting.
What happens to our Proxmox subscription?
It stays in place. The subscription gives you access to the enterprise repository and, depending on the level, to support from Proxmox itself. Our service does not replace it.
