WHY TRUST CODESHIELD

Trusted & Independently verified.

“We recently engaged CodeShield to carry out penetration testing for one of our clients, and the service was nothing short of excellent. Both Tom and Dan were extremely knowledgeable and professional throughout the process. Their clear communication and technical expertise made the entire experience smooth and efficient. We look forward to working with them again when the need arises and would highly recommend their services.”

Darren Walsh

“We’ve used a number of CREST assured pen testing companies over the last 10 years, however CodeShield have been the first to exceed my expectations. The team listened to what we wanted, added their own expertise and recommendations and then performed a bespoke test with meaningful, well set out results. The follow-up meetings between our dev team and the testers was well run and respectful. I highly recommend CodeShield and will be engaging them again for our future testing.”

Daren Martin

“We used CodeShield for a security and penetration testing audit for one of our clients. As well as being technically competent and very efficient in carrying out the audit, they were extremely communicative and collaborative throughout the whole process. The result is that we are now very well equipped for the big launch and rolling out the platform to Schools securely.”
