Besides being a HAM I am an IT Security Expert at Ventus IT Professionals. You can find my profile (in dutch only, sorry) for the more intimate details, but I will give a short summary here.
For Ventus IT Professionals I help customers get the most secure cloud, network, server and the like. I secure, design, build and sometimes support (virtual) infrastructures, built around Microsoft Windows, Citrix, VMware, Cisco and VOIP. Sometimes it's dull and boring, sometimes its fun and challenging, but it pays the bills. =8-)
