Dr. Andreas Rieke was already interested in "security in fast networks" when he obtained his doctorate from the FernUniversität (distance learning university), Hagen. Afterwards, at the beginning of 1999, he founded ISL, with the intention of putting into practice the theoretical knowledge he had acquired during his studies. The result – which already materialized in 2003 – was ARP-GUARD, a solution specifically aimed at protecting against unauthorised hardware and internal attacks.

Supplementary to this, training is provided for external and internal sales staff, and presentations and exhibitions are organised and staged.
