# Servers & clusters. For systems that must not stop.

Source: https://vetosec.at/en/servers/

We build servers that keep running when one fails. We secure them and look after them. That is our core business.

- **Proxmox** instead of VMware
- **Linux** hardened
- **15 minutes** to a hardened server

## What we do

- [**Server clusters on Proxmox**](https://vetosec.at/en/solutions/proxmox-cluster/): If a server fails, everything keeps running. Also as a move off VMware.
- [**Linux hardening**](https://vetosec.at/en/servers/linux-haertung/): Set up to a security standard, with a report for auditors.
- [**Managed Linux**](https://vetosec.at/en/servers/linux-betreuung/): Updates and monitoring. Every change checked and recorded.
- [**Rootkit analysis**](https://vetosec.at/en/servers/rootkit-analyse/): Suspect a hacker? We check down to the system core.
- [**File server instead of NAS**](https://vetosec.at/en/solutions/fileserver/): Storage that notices errors, with a second copy.

## What we run

Real systems running for clients.

- [**Server cluster**](https://vetosec.at/en/solutions/proxmox-cluster/): Several servers, one interface. If one fails, the machines start on another.
- [**One login for everything**](https://vetosec.at/en/solutions/single-sign-on/): One sign-in for every app, confirmed on the phone. When someone leaves, you lock one account.
- [**Company cloud**](https://vetosec.at/en/solutions/managed-nextcloud/): Share files like with Dropbox. The data stays with you or in the EU.
- [**Firewall**](https://vetosec.at/en/solutions/firewall/): Separate networks for office, servers and guests. A break-in stays in one area.

Also: [File server instead of NAS](https://vetosec.at/en/solutions/fileserver/), [Backup](https://vetosec.at/en/solutions/backup/), [Working from home](https://vetosec.at/en/solutions/fernzugriff-vpn/)

## Technology

Proven software, no licence tie to us.

- [**Rocky Linux · RHEL · AlmaLinux**](https://vetosec.at/en/servers/linux-haertung/): Hardened server OS
- [**SELinux**](https://vetosec.at/en/servers/linux-haertung/): Locks in every service
- [**ZFS**](https://vetosec.at/en/solutions/fileserver/): Storage that detects errors
- [**OPNsense**](https://vetosec.at/en/solutions/firewall/): Firewall and separate networks
- [**Authentik**](https://vetosec.at/en/solutions/single-sign-on/): One login for everything

## VMware

**VMware got expensive. Proxmox needs no licence.**

Since the Broadcom takeover many pay several times as much. We move your servers machine by machine. The way back stays open until everything runs.

## NIS2

**NIS2 applies since 1 October 2026. We implement the technology.**

Affected companies must register by the end of 2026. Suppliers need evidence too. Hardened servers and a clean log are a big part of it.

## Frequently asked questions

### We have our own IT team. Does that fit?

Yes, that is common. We take on single tasks or all of operations. Who does what is in the contract.

### What does moving off VMware cost?

It depends on the number of servers and machines. After a call you get a project price. Proxmox itself needs no licence.

### Do we get your automation?

No, that is our tool. You get network plan, runbook, reports and all credentials.

### Who is this for?

For companies with about 30+ staff and anyone whose servers must not stop. With or without an in-house IT team.
