Martin Brünn

Martin Brünn is a passionate IT expert who began exploring cybersecurity and hacking as early as the age of 14—long before the internet boom. In the era of acoustic couplers, BTX, phone phreaking, and FIDOnet, he laid the foundation for what would become a lifelong career in IT security.

He turned his passion into a profession by founding ADVANCED Systemhaus GmbH during his computer science studies. Early on, he recognized both the enormous potential and the growing risks that digital connectivity through the internet would bring. He also saw that many businesses and IT departments were becoming overwhelmed by rising demands, regulatory requirements, and increasingly complex threats—prompting him to develop practical and effective security solutions.

Martin Brünn is a cybersecurity and Zero Trust specialist from the very beginning. For decades, he has advised mid-sized companies on IT security strategies and has implemented modern, holistic protection concepts. His work is driven by a focus on efficiency, sustainability, and real-world applicability—always with the goal of safeguarding business operations while significantly relieving the burden on internal IT teams.

Long-term, Hanseatic-style partnerships and trusted business relationships form a core pillar of his approach. One of these vital partnerships is with ThreatLocker, a leading security provider whose product suite we leverage to establish a strong and stable First Line of Defence and a comprehensive Zero Trust Protection for our customers — especially effective against emerging and unknown threats.
