IT care and infrastructure for businesses in and around Kraków. We design, deploy and maintain your systems so your team can forget about them.

B.A.C.K.U.P.

Our IT care model: six areas we secure for every client. The name is no accident – in IT, everything comes down to a good backup.

B – Bastion security

Firewalls, VPN and network segmentation. Intruders stay out, while your staff work safely from anywhere.

  • FortiGate
  • Ubiquiti
  • VPN
  • Segmentation

A – Automation

Infrastructure as code and automated deployments. Every change is reviewed, repeatable and reproducible.

  • Terraform
  • Terragrunt
  • GitLab
  • GitHub
  • CI/CD

C – Cloud & compute

Virtualisation and cloud: rollouts, migrations, expansion. Your hardware works harder and your services are reachable from anywhere.

  • VMware
  • Proxmox
  • Ubuntu
  • Azure

K – Knowledge

Documentation, procedures and change control ready for audits and GDPR. You know what you have and who can access it.

  • Documentation
  • Audit
  • GDPR

U – Uptime

Ongoing care on a subscription: round-the-clock monitoring, updates and a helpdesk. We often know about a problem before you notice it.

  • Zabbix
  • Landscape
  • Helpdesk

P – Protected data

Backups with regular restore tests and a disaster recovery plan. An outage becomes a short pause, not the end of your business.

  • Veeam

Banking-grade standards for every business

We work where downtime is measured in minutes and every change goes through an audit. We apply the same rules for every client, whatever the industry.

  • 82.32%

    Finance & banking

    Infrastructure for companies serving banks and financial institutions: high availability, controlled changes and regulatory compliance.

  • 14.13%

    Healthcare

    Clinics and medical practices: protected patient data, GDPR compliance and equipment that never fails mid-appointment.

  • 3.32%

    Hospitality

    Hotels and restaurants: networks for guests and staff, reliable booking and sales systems, data backups – even in peak season.

  • 0.23%

    Manufacturing

    Production companies: networks for offices and shop floors, and systems that keep production running.

Technology, in plain words

You don't need to know these names. Just what they do for your business.

  • FortiGate

    A business-grade firewall guarding the entrance to your company network. It blocks attacks, filters traffic and handles secure VPN connections.

  • Ubiquiti

    Switches and Wi‑Fi managed from a single dashboard. A stable network in the office and on the shop floor, without complicated upkeep.

  • VPN

    An encrypted tunnel into your company network. Your staff work remotely as if they were in the office.

  • VMware

    Runs many independent “virtual computers” on a single server. Less hardware, faster system recovery.

  • Proxmox

    An open-source alternative to VMware. The same virtualisation benefits without expensive licences.

  • Ubuntu

    A stable, free operating system for servers. Long-term support and regular security fixes, with no licence costs.

  • Azure

    Microsoft's cloud: servers, email and data available from anywhere. You pay only for what you use.

  • Zabbix

    Watches servers, networks and disks around the clock. When something starts failing, we get an alert before you feel it.

  • Veeam

    Backs up your servers and data automatically. After a failure or an attack, we restore everything quickly.

  • Landscape

    Manages updates for Ubuntu servers from one place. We automate patching so updates are promoted from dev through test to production – only what has already worked reaches production.

  • GitLab

    Your infrastructure configuration with a full change history. You know who changed what and when – and can roll it back.

  • GitHub

    A platform for storing code and configuration. Every change is described, reviewed by a second person and kept in history.

  • CI/CD

    An automated “production line” for changes. Every fix is tested and deployed the same way, without manual mistakes.

  • Terraform

    Infrastructure written down like a recipe. Your environment can be rebuilt from scratch, identically every time.

  • Terragrunt

    Keeps many environments – test and production – in order. Less repetition, less room for error.
