“As part of delivering services to our clients we are regularly requested to conduct penetration tests on our applications and servers. As part of our own due diligence we engaged Prism Infosec to review some of our web sites and their team found issues and vulnerabilities that other providers failed to identify. We were impressed with Prism Infosec’s level of service and the quality of their deliverables and will certainly use them again for future assessments”.

“Schroders required us to procure the services of a CREST approved penetration testing company to review the security of our web application and its implementation in the cloud on Amazon Web Services. We engaged Prism Infosec who assisted us with the end-to-end delivery of the requirement, including scoping the work, conducting the review and providing the report and summary of results. Prism Infosec produced a statement of work which offered real value and they understood and identified the type of tests that our client needed to ensure adequate assurance of the security of our implementation. We were impressed with the quality of the service and report that they delivered as well as their communication throughout the process and it helped us to move the project forward successfully with our own client. We would have no hesitation in recommending Prism Infosec.”

“I have worked with Phil Robinson and his team in two of my previous positions as Information Security Manager at Yorkshire Building Society (UK) and Vanquis Bank UK / Provident Financial Group. This included the delivery of internal enterprise class web application assessments and red team reviews respectively. The tests have always been delivered with the utmost professionalism with respect to the banks’ service levels, the quality of test delivery onsite and the detail in the subsequent reports. Additionally, risks and results were well articulated to all levels of the business and were at all times pragmatic and prioritised correctly. I would have no hesitation in recommending Prism Infosec for the delivery of cyber assessment work within a Financial Services environment.”

“Prism Infosec were the perfect partner for our pen testing needs. Right from the start they were highly engaged and extremely responsive, supplying?quick feedback to all our queries. They provided timely updates throughout the testing engagement and delivered a detailed technical report, complete with remediation?advice for all identified issues, at the end. Their experience with API testing was obvious from the start due to the questions their testers asked and their testing methodology. I thoroughly?enjoyed working with Prism and cannot wait to work with them again”.
