Why open source

What open source gives you
Cost-control Independence Security

Our stack is open source. There are three reasons for that:

No licence costs
You pay for our work, not for licences. No price hikes, no hidden costs.

No vendor lock-in
You decide, not the vendor. Open standards, so you can take over or switch whenever you want.

Security through openness
Open code instead of a black box: many eyes review it, gaps get closed fast. Your own AI can check it too.

We run the stack for you, document everything in full and hand it over at any time — to you or the next provider — free of charge. That doesn't make us cheap. It makes our pricing honest.

13 categories

What we use
category by category

We didn't invent these 13 categories: they follow the technical measures that ISO27001 (Annex A) and NIS2 require from organisations — from identities and access to logging, backup and awareness. Every requirement is mapped to a specific tool.

Just as important: we replace nothing that already works well for you. Proven tools stay, we just fill the gaps instead of selling you expensive licences.

Where ITAT is listed, we have built open-source components that make integration easier and extend functionality.

Why we build it this way

Three sentences that apply to us

We walk you through the stack

Because it's open. With a closed system that wouldn't be possible. That thoroughness lands directly with you.

No licence cost for you

What we save on licences goes into the price, not into the margin.

No vendor lock-in

No vendor lock, no commissions. Our recommendations fit you, not our sales partner.

Build less, use it better

Technology with direction
not more but the right fit

You don't have to rebuild everything for things to get better. We look at your existing stack with you, sort the options and say clearly which solution makes sense, what it costs and what effort is involved.
