What our clients say about us

UnderDefense stands out in the field of penetration testing because they understand the importance of security risks and are able to map it to the domain in which their client is operating. Simply using automated scanning tools is not a replacement for smart, intelligent people with a deep understanding of security related issues. Taking penetration testing to the next level, using real people to test systems and interpret the results.

Understanding the risks involved we wanted to guarantee our users with a hack-proof application for them. Working with UnderDefense we were able to gain better visibility of the techniques used against mobile applications, which helped us set preventative measures to protect our key systems, resources, and client data.
