InterResearch's production server is placed in a basement in Søborg – one of the safest data centres in Europe.

Finger prints, identification cards, passwords, surveillance cameras and walls of steel are just some of the serurity installations to be found there.

The centre is catastrophe-proof with the same level of physical security as military plants.

The centre contains wall of steel, surveillance monitoring, an emergency electricity generator plus heat and flood alarm systems. If water forces its way in from above, gutters within the ceiling will prevent the water from damaging the hardware.

An alarm is set off if a door is open for more than 25 seconds.
