OUR APPROACH

We know what works—and what doesn’t.

Cybersecurity only delivers value once it's understood as a business risk. That's exactly where we start.

Many organizations invest in security without a clear view of their most critical risks. We provide that clarity by identifying risks, assessing resilience, and prioritizing measures by impact and effort so investments target the areas of greatest need.

Our roots are in practice. Years in the industrial cyber insurance industry showed us where the real costs of an incident arise — and they're rarely where you'd expect. This knowledge shapes which measures we recommend, and which we don't.

WHY TEUTOSEC

We know what works —
and what doesn’t.

Technical depth meets business thinking
Cybersecurity only delivers value once it's understood as a business risk. We think in both dimensions at once: technical substance and business consequence.
The true cost of a cyber incident
Years in the industrial cyber insurance industry showed us where the real cost of an incident lies — and it's rarely where you'd expect. This knowledge shapes which measures we recommend.
At home in two worlds
Experience across NATO operations, European finance, and international insurance, paired with a deep understanding of small and medium-sized businesses.
Advice that serves your interests
No product recommendations, no vendor lock-in. Our recommendations are guided solely by your business and operational priorities.

Sebastian Hess

Co-Founder & Managing Director, TeutoSec | Cybersecurity and Cyber Risk Expert
Sebastian Hess, co-founder and managing partner of TeutoSec, brings more than 20 years of cybersecurity and cyber risk management experience across NATO, the German Armed Forces, and the international insurance industry to small and medium-sized businesses.br>
He combines operational and strategic cybersecurity experience with commercial thinking and executive-level governance — a combination rarely found in the market. His career spans NATO cyber operations, CISO responsibility in the Belgian financial sector, and several years in the international cyber insurance industry, where he assessed the real financial consequences of cyber incidents for a wide range of companies. With experience across the US, Europe, LATAM, and APAC, he is equally at home in English- and German-speaking business environments.

After finishing school, Sebastian chose an officer career and served in various IT leadership positions in Germany and the US from 2001 to 2008. In 2008 he joined NATO, initially leading part of the AWACS software development effort in Germany. In 2011 he was appointed Chief Theater Information Assurance Officer — the in-theater equivalent of a CISO — for the NATO mission in Afghanistan, responsible for securing the network in the field. From 2012 to 2015 he then led the build-out of NATO's Cyber Defense Capability across the alliance as Deployment Manager, based in Belgium.

In 2015 Sebastian moved into the private sector: as the first CISO of Isabel Group, Belgium's largest fintech company, he built the information security function from the ground up. From 2017 he led the build-out of the Cyber Risk Engineering & Consulting function across EMEA, APAC, and LATAM at AIG as Head of International Cyber Risk Advisory. In 2023 Sebastian joined the RiskPoint Group as Chief Cyber Risk Officer. In 2026 he founded TeutoSec to bring cybersecurity and cyber risk advisory — built on this experience from defense, NATO, and the international insurance industry — to small and medium-sized businesses.

Sebastian is a co-author of the German, European, and North American editions of the Cyber Risk Handbook for Corporate Directors. He holds a Master's in Computer Science from the Bundeswehr University Munich, a Master's in Executive Leadership from Georgetown University, and an LL.M. from KU Leuven, Belgium. He is a Certified Chief Information Security Officer (C|CISO) and a Certified Information Systems Security Professional (CISSP).
