Business Philosophy

RedTeam Pentesting acts as a reliable partner to its clients in enhancing IT security. Absolute confidentiality regarding the conducted penetration tests is a given. Unlike many other companies, we are offering penetration tests only. In particular, this means that the execution of the test is not aimed at selling any additional services. Instead, our penetration tests provide the most objective picture of IT security possible.

Both the planning and execution of penetration tests are conducted individually and in close consultation with the client. Our high-quality results reveal real risks and provide practical recommendations and solutions directly contributing to the improvement of IT security. RedTeam Pentesting’s professional and responsible approach ensures smooth operation, even with critical production systems.

At RedTeam Pentesting, intensive collaboration among penetration testers is at the forefront. This collaboration enables us to develop creative approaches for penetration tests and achieve optimal results tailored to the needs of each client. Within the team, penetration testers complement each other with their expertise and individual skills. Together, we develop and implement innovative and tailored methodologies. In addition to direct communication within the team, the penetration testers regularly exchange ideas and knowledge. All of RedTeam Pentesting’s employees have extensive experience and comprehensive knowledge in various areas of IT security. Furthermore, they regularly share their expertise through publications in the field of IT security.


We are currently seeking additional penetration testers to strengthen our team. More information about our working methods and environment, as well as details on how to apply, can be found on our German jobs webpage.
