Work History

Radiant Systems


Patrick started work at Radiant Systems immediately after graduating from Georgia Tech. He joined the Epsilon product development team; Epsilon is a middleware application that processes electronic tenders, connecting points of sale to a variety of payment processing hosts. Patrick implemented several new host interfaces, primarily for the Petroleum Convenience Retail market. He also worked to institute security improvements to bring Epsilon into compliance with Visa’s PABP/CISP standard.



At about the same time that Radiant Systems was acquired by NCR, Patrick began acting a security subject matter expert for the PCR division of NCR, including the Epsilon, Sigma, and RPOS products. In this capacity, he was responsible for ensuring that these products were implemented in compliance with PA-DSS and remediating security issues. Beyond guidance, he directly implemented the security architecture of the Epsilon and Sigma products. At the same time, Patrick took over leadership of the Epsilon Continuous Improvement team. In this role, he ensured that Epsilon defects from over 150 payment host interfaces were quickly resolved.



Patrick Watson is an Application Security Architect specializing in electronic payment systems. He joined Radiant Systems, later acquired by NCR Corporation, to build payment middleware for point of sale suites. Working with over 50 payment processor interfaces, primarily in the petroleum market, Patrick has designed and implemented many of the security systems protecting your credit card and personal data. No stranger to PA-DSS and PCI DSS, he continues to champion security beyond compliance. He holds a Bachelor of Science in Computer Science from the Georgia Institute of Technology in addition to CISSP, CSSLP, and CIPP/US certifications. In his spare time, he might be found playing games, reading, browsing the web, or playing with his cats.
