Cybersecurity for small and medium-sized enterprises (SMEs)

My name is Lars Marcus Wüstenberg, a cybersecurity specialist with more than 15 years of experience – from research projects at the University of Hamburg to the practical hardening of real-world systems. Together with a close-knit core team and long-term freelance experts, I help SMEs secure their IT environments in a targeted and sustainable way.

Reports from institutions such as the Federal Office for Information Security (BSI) in Germany and various industry associations show that SMEs are increasingly becoming targets of cyber attacks. Limited resources combined with growing complexity make structured security work essential.

Threats beneath the surface

The internet is a digital ocean full of invisible threats. Many attacks abuse well-known vulnerabilities and misconfigurations. With our internal methodology “FreeShark” we help you make these “sharks” visible and reduce your attack surface.

Our work is based on recognised standards and recommendations such as BSI guidelines, current security research and established best practices.
