We are a consulting and auditing company for IT security. In true
boutique quality. As in-depth specialists for manual penetration tests and
offensive IT security, we have over eight years of experience and more than 400

vulnerability analyses, well-founded risk assessments and clear, directly

security of your systems.

know the regulatory requirements as well as the operational realities
of your industry.

of equals. We stand for Hanseatic values – and for implementing IT
security clearly, honestly and effectively.
