What we do for you

Two areas, one principle: we look at how things really are, explain it in plain language and implement what is actually needed.

For businesses

Gyms, building managers and small companies

Small operations rarely have their own IT department, but they carry the same risks as large ones. We close that gap project by project, with no fixed costs and no vendor lock-in.

  • Access control and badge systems A full inventory of cards, readers and controllers. You get a clear answer on what can be cloned and what cannot, and what the path to a secure system looks like.
  • Migration away from outdated card technology Concept, schedule and budget for the switch, including a comparison of the quotes from your suppliers. We do not sell hardware ourselves.
  • Network design and segmentation Guest network, staff network and operational technology (tills, cameras, access control) properly separated, so one problem does not immediately affect the whole building.
  • Firewalls, routers and switches Selection, configuration and a rule set that still makes sense two years from now. Secure remote access over VPN instead of open ports.
  • Security check with a priority list Which devices are on the network, where default passwords are still in place, which firmware is out of date, how backups are doing. The result is a report that says what comes first and what can wait.
  • Documentation Clear records of your network and your access systems, so you stay independent, including from us.

For private clients

IT help at home

On site in the Zurich area, at a fair hourly rate. We explain what we are doing as we go, so you can manage on your own afterwards.

  • A home network and Wi-Fi that works everywhere Find the real cause of poor coverage, place access points correctly, set channels and bands sensibly, instead of just buying more equipment.
  • Install and configure a router or firewall From replacing the provider's box to setting up a proper home firewall, configured deliberately rather than left at factory defaults.
  • Security at home A separate guest network, smart devices and cameras isolated from the rest, default passwords replaced, updates switched on, parental controls configured.
  • Devices and data Printers, NAS units, network storage and smart home devices connected properly, plus a backup that actually runs.
  • A second opinion Got a quote or a suspicion and want to know whether it holds up? We will look at it neutrally.

Straight talk

What we do not do

Being upfront saves everyone time. These things we deliberately leave out:

  • No hardware sales, no commissions We recommend what fits, not what pays us.
  • Clear service hours instead of a 24/7 promise We work in agreed time windows and reply within 24 hours. If you need a round-the-clock hotline, a larger provider will serve you better. We would rather say so upfront.
  • No websites, no marketing, no accounting software Networks, access and security. That is where we stay.

Not sure what you need?

That is normal, and exactly what the first conversation is for. Describe your situation briefly and we will work out the rest together.
