Charles has been passionate about computers since he was nine (9) and was gifted a secondhand IBM XT. Throughout high school, he assisted with IT support, giving him insight into how security can play an important role in an organization. This sparked a curiosity of why security was so often relegated to an afterthought and who else had noticed. Having an affinity for technology allowed him to explore these questions. While exploring, a whole new world appeared. Here was a passion shared by the many denizens of the nascent Internet. As his years in the computer industry expanded his experience, the passion to understand the ‘why’ continued to grow. This culminated in him landing a position as a software developer at a security company, where he spent six (6) years building the development department before moving on to working at TrustedSec.
