Joshua Feldman (CISSP) is Senior Vice President for Security Technology at the Radian Group - a real estate and mortgage insurance conglomerate. His mission is focused on protecting over 10M US consumer financial records. He is the executive responsible for all aspects of Radian's technical security program. Previous security roles included work at Moody's Credit Ratings, Corning Inc, and the US Department of Defense and Department of State.

In 2008, Joshua was Eric's student when studying for the CISSP exam and was so impressed with Eric's mastery of the materials that he invited Eric to work with him at the DoD. Quickly after starting work, Eric invited Seth. That project ran successfully for over eight years - a testament to the value brought for US military cyber professionals.

Joshua got his start in the cyber security field when he left his public-school science teaching position in 1997 and began working for Network Flight Recorder (NFR, Inc.), a small Washington, DC based startup making the first generation of Network Intrusion Detection Systems. He has a Bachelor's of Science from the University of Maryland and a Master's in Cyber Operations from National Defense University. He currently resides in Philadelphia with his little dog, Jacky-boy.
