For techies: Feilner IT is providing help and experts for the OSI Layers 8, 9 and 10.
We come in where the classical OSI standard stops. Since it actually defines only seven layers (from from hardware – Layer 1 – to Applications and User interfaces – Layer 7), Layer 8 (what is happening “in front of the screen”) is where our domain starts. We are actively supporting users , organisations (Layer 9) and government institutions (Layer 10) with strategic and hands-on writing, consulting, and research.
