# Infrastructure for companies with 30+ staff.

Source: https://vetosec.at/en/industries/sme/

Own servers, a cluster, a production online shop or ERP. We build for resilience and run the whole environment or single services. Your internal team gets a second line.

- **30+** staff
- **Services** single or full
- **NIS2** in scope or supplier

## Typical problems

What often happens in growing companies.

- **One server everything depends on**: If it fails, shop, ERP or file server stop until a replacement arrives.
- **Everything depends on one person**: Holiday, illness or resignation, and nobody knows the systems.
- **Updates get postponed**: Nobody wants to risk downtime, so vulnerabilities stay open for months.
- **Customers ask for NIS2 evidence**: Questionnaires on backup, access and incidents land on your desk.

## What we take care of

What we build and run for you.

- **Highly available servers**: Proxmox clusters: if a node fails, systems keep running on the others.
- **Patches in maintenance windows**: Planned, tested, applied outside business hours.
- **Monitoring and SIEM**: Infrastructure and security events in one view on our own platform, with a human checking every relevant alert.
- **Single services or everything**: File server, SSO or backup as a managed service, or operation of the entire environment.
- **Immutable backup**: Offsite, ransomware-proof, restores rehearsed regularly.
- **Documentation for evidence**: Network plan, runbook and change log. The basis for NIS2 and ISO evidence.

## Typical environments

Environments we run.

- **Online shop & e-commerce**: Production B2B and B2C shops with databases, integrations and peaks.
- **Manufacturing**: Office IT and machine network separated, remote access controlled.
- **Hospitality & shift work**: Systems that must run evenings and weekends.
- **Multiple sites**: Branches connected via VPN, monitored centrally.

## Three ways to start with us.

- [**IT security check (from €1,299)**](https://vetosec.at/en/services/it-check/): We come by and check how easily a hacker gets in. After two weeks you have a list of what to do.
- [**External security analysis (from €249)**](https://vetosec.at/en/external-security-analysis/): We look at your company from outside, like a hacker. No access needed. Report in 5 working days.
- [**Ongoing support (fixed monthly price)**](https://vetosec.at/en/services/it-support/): We look after servers, updates and backups. One contact, one fixed monthly price.

## Frequently asked questions

### Do you replace our internal team?

No, we complement it. Typically we take servers, backup, security and on-call, internal IT looks after users.

### Is around-the-clock on-call available?

It is possible together with cooperation partners. Availability is agreed individually.

### Do you help with NIS2?

Technically yes: backup, access, monitoring, incident handling and documentation. Legal assessment stays with your counsel.

### What does it cost?

Builds as fixed-price projects, operations at a fixed monthly price. We quote after an assessment, often an IT Check.

## Managed services and infrastructure for mid-sized companies in Austria

vetosec works with companies of about 30+ staff whose business depends on IT, building HA infrastructure and running it with monitoring, SIEM, patching and backup.

Many are in scope of NISG 2026 or asked for evidence as suppliers. Documented infrastructure, tested backups and traceable incident handling are the technical basis.
