The Company History

2004 - The Idea

In December 2004, RedTeam Pentesting was founded as a research group at the Laboratory for Dependable Distributed Systems (Department of Computer Science 4, RWTH Aachen University). From the outset, it has been our priority to deliver high-quality work to our clients and to achieve objective and independent results. Therefore, we focus exclusively on penetration testing and do not offer any other services. Our teamwork fosters creativity, enables innovative solutions, and helps uncover even complex security vulnerabilities that might otherwise be overlooked. Our scientific approach and methodology have proven to be pioneering and significantly differentiate us from other penetration testing providers. To this day, this fundamental philosophy remains an integral part of our work, underscoring our quality and effectiveness.

2005 - The Beginning

The outstanding quality of RedTeam Pentesting’s services quickly gained recognition, revealing that a research group as an organisational structure was no longer sufficient. It became evident that an appropriate legal framework was necessary for the continued operation as an independent company. In order to achieve this goal quickly and enable the further development of RedTeam Pentesting, the transformation into an independent department of Nomis Development GmbH was completed in October 2005.

2006 - The Founding

In parallel with the already independently operating department, RedTeam Pentesting GmbH was founded to facilitate a seamless transition into a standalone GmbH. Over the following years, RedTeam Pentesting proved to be a company in consistent demand for penetration tests. While our clients initially came mainly from the German-speaking region, RedTeam Pentesting increasingly established itself as a sought-after international service provider. A central value for the company has been and continues to be absolute discretion towards our clients. In addition to our services, we maintain a presence in research and knowledge dissemination, which has been part of our company philosophy from the outset. Since its inception, we have also placed great emphasis on continuously evolving the penetration testing service in line with our clients’ needs, leveraging creativity and technical expertise to consistently achieve relevant and insightful results.


Due to its consistently outstanding performance, RedTeam Pentesting gained attention beyond the business world. In January 2016, as part of the “GERMANY AT ITS BEST” campaign by the state of North Rhine-Westphalia, we were honored for our achievement as a worldwide leading company specialised in penetration testing. “GERMANY AT ITS BEST” is a location marketing campaign by the Ministry of Economic Affairs of the state of North Rhine-Westphalia and the state-owned economic development agency NRW.INVEST. It presents North Rhine-Westphalia as an innovative business location with excellent conditions for companies. In the “GERMANY AT ITS BEST” campaign by the state of North Rhine-Westphalia, outstanding companies and achievements are recognised, contributing to strengthening and promoting the economic location of North Rhine-Westphalia. Companies are honored for their innovation, sustainability, and international success.


RedTeam Pentesting’s successes were also recognised on a local level, leading to the company’s nomination for the AC²-Innovationspreis Region Aachen in 2017. This award annually recognises companies, institutions, or individuals who have made a significant contribution to the development of the economic location in the region of Aachen.


Since September 2022, RedTeam Pentesting has been located in new, modern offices in the heart of downtown Aachen. Our new headquarter in the historic “Kapuziner Karree” was opened after an exciting several-month renovation. With spacious, modernly designed premises, our employees enjoy an optimal working environment. The central location is not only conveniently accessible but also the green courtyard and the numerous restaurants in the area invite to spend lunch breaks in a relaxed atmosphere. As part of these exciting changes, we have also modernised our company logo to emphasise our innovative and future-oriented approach.
