IT Audit

Linq42 is the IT security advisory company of Marc Smeets. I'm a seasoned IT security consultant that understands IT security on the most technical level. But I believe IT security isn't solely about the technical issues. I recognise the equal importance of a quality report and advice that you can actually use and that aligns with the culture, people and processes within your organisation.

I see IT security engagements not as the goal, but as a measure. The goal is to become more resilient to attacks. If you share that goal, contact me to see if I can help you out.


I'm passionate about IT security done right, experienced in helping clients and qualified in relevant fields.
