RedTeam Pentesting offers individual penetration tests, short pentests, performed by a team of specialised IT security experts. Hereby, security weaknesses in IT systems (e.g. networks, applications or devices) are uncovered and can be remedied.

As there are only few experts in this field, RedTeam Pentesting wants to share its knowledge and enhance the public knowledge with research in security related areas. The results so far are public security advisories which gained national and international attention.

In contrast to many other companies, RedTeam Pentesting specialises in pentests. A detailed description of pentests can be found on the pentest pages, frequently asked questions are answered in the FAQ section.

If there are any further questions, do not hesitate to contact us via email, fax or phone.
