# Managed Linux servers. Every change checked.

Source: https://vetosec.at/en/servers/linux-betreuung/

We keep your Linux servers current and secure. Nothing happens without a test and approval. Everything is recorded.

- **Approval** before every change
- **Log** cannot be altered
- **Fixed price** per month

## What you get

- **Updates without surprises**: First a dry run, then approval, then the update. The same on every server.
- [**Problems spotted early**](https://vetosec.at/en/services/monitoring/): We watch every server. An engineer looks at every important alert.
- [**Everything traceable**](https://vetosec.at/en/compliance/nis2/): Who changed what, when and why. The log cannot be faked. Good for NIS2 and ISO 27001.
- [**Security stays high**](https://vetosec.at/en/servers/linux-haertung/): We check regularly that every server is still as secure as on day one.

## How an update runs.

- 08:52: **Hole found.** Six servers affected.
- 08:53: **Dry run.** Nothing changed yet.
- 09:14: **Approval.** An engineer approves.
- 09:15: **Update.** The same on all six servers.
- 09:16: **Logged.** Cannot be changed afterwards.

## The log

- Audit log: Every action goes into an immutable log: backups, alerts, approvals. Entries are chained and anchored with timestamps, so nothing can be changed afterwards.

## Price

**One fixed monthly price. After an assessment.**

Fixed monthly price after an assessment. With an in-house IT team we split the tasks in writing.

- **Configuration**: Servers, hardening and firewall rules as code, idempotent runbooks, dry run before every change.
- **Approval**: Role-based approval with a reason, optional four-eyes principle with your team.
- **Audit log**: Every entry carries the SHA-256 hash of the previous one, anchored with a timestamp, export as PDF.
- **Monitoring**: Agent per server, file integrity, vulnerabilities and sign-ins in the SIEM, alerts as triggers for runbooks.
- **Updates**: Security updates in maintenance windows, staggered across nodes, service checks afterwards.
- **Compliance**: Scheduled OpenSCAP scans, report per server with open items.
- **AI assistance**: Analysis of output and logs by a language model, execution only by the engineer.
