Cory is a senior penetration tester at KPMG. He has worked across the trade in testing infrastructure, web, desktop, and mobile applications, and cloud environments. He primarily focuses on the Defence & National Security space, but has worked with a range of clients in industries from banking to health & care, CNI, and NGOs. He became a penetration tester after reading War Studies at King's College London, during which he exchanged at Yonsei University, South Korea, where a budding love of all things tech began.

Having come from a non-traditional subject, he seeks to support the the entry of individuals from non-traditional backgrounds into the trade, the sharing of new techniques, and the professionalisation of the trade as a whole.
