Who is this for? The tools and courseware here are for network and security practitioners, integrators, and IT generalists working on systems that have to actually work in the field.

What does "boutique" mean? Boutique means small-scale, high-specificity work. Hans does not run a 50-person consulting firm. The practice is one person, deeply specialized, working on problems that do not fit a tidy category.

Where is Hans based? Ontario, Canada. Work spans Canada and the United States.

What sectors does Hans work in? Government, public safety, defence, critical infrastructure, healthcare, airports, and enterprise environments.
