Katy Winterborn is a Senior Security Consultant with NCC Group where she works primarily with a diverse range of companies to secure their infrastructure, both internally and externally as well as providing advice on web application security.

In addition, Katy enjoys working in exploit development and has written a whitepaper on exploiting a vulnerability in Internet Explorer. This work has led to her being one of the team who deliver NCC’s training on reverse engineering fundamentals and exploit development.

With a background in network defence and intrusion analysis Katy believes that in order to fully secure a system an understanding of both offense and defence is critical. This has resulted in the publication of a paper for the Institute of Engineering and Technology on Network Security Monitoring and Analysis as well as the creation of a course on penetration testing for network analysts.

Katy gained her Master of Mathematics in Maths and Computer Science from the University of York and has gained numerous industry qualifications including CISSP, Crest Certified Network Intrusion Analyst (CCNIA) and Crest Registered Tester (CRT). In her free time Katy is a keen photographer and enjoys cooking a wide range of cuisines.
