A fascinating activity, by which we learned a lot – anytime again.
Operations Manager, Electronics
Overall, we were very impressed with the high level of professionality and competence of RedTeam Pentesting. They demonstrated deep knowledge with respect to many different systems ranging from Windows to Unix-based systems, to low-level administration tools that are hardly known, to development problems in languages such as PHP which may lead to new exploits. The knowledge that we aquired during the penetration test with them helped us to improve our system administration and increase the security of our systems.
CSO, Telecommunications
RedTeam Pentesting does an unbelievably sophisticated job in analyzing your system. Even if your software already has a high security standard, you will nonetheless be amazed and thankful for issues RedTeam Pentesting will find. Your systems will not only be more secure after they have been tested by RedTeam Pentesting, you and your developers will also be a lot wiser and will be able to design and implement systems that have a higher security level than before.
Head of Development, Software Development
Professional penetration test with very good preliminary discussion and an impressive presentation of the vulnerabilities and results.
Head of Commerce, Head of IT, Systemadmin, Food Industry
With the detailed presentation of each vulnerability in the report and the extensive evaluation during the final presentation it was possible (without further research) to develop practical actions to remedy the vulnerabilities.
Head of IT, Health Insurance
A big 'thank you' to RedTeam Pentesting for the professional advice (on short notice) and the subsequent pentest of one of our most important new applications. We can now go live in good conscience.
