Tom Arnold is a cybersecurity expert, digital forensics investigator, and educator. He lectures on digital forensics and incident response at San Jose State University and the University of Nevada, Las Vegas, where he is also helping to develop a new digital evidence and forensics degree program. A co-founder of Payment Software Company (PSC), now part of NCC Group, Arnold has led large-scale breach investigations-some involving more than 7,000 servers-and served as lead investigator in complex threat-hunting operations. He has testified before the U.S. Senate and House on cybersecurity legislation. He also serves as a producer and writer for Cloud 10 Studios, a full-service animation studio that creates original series, long-form content, and commercial projects.His novel The Digital Detective: First Intervention was inspired by a real-life cybersecurity scare when Arnold's grandson was approached by a stranger on Roblox despite parental controls. That moment launched Arnold's mission to help families and schools recognize hidden online dangers-and to give kids the tools they need to stay safe in the digital world. The Digital Detective: First Intervention was released early 2025. The story is about young teenagers who inadvertently fight cyber terrorism. It's a quick read that even adults will enjoy, and the story exposes youth in an educational way to the pitfalls of Internet technology.
