Brad Deflin
Founder of Total Digital Security

-
Visionary and Pioneer of Cybersecurity for the Private Domain
Brad Deflin founded Total Digital Security in 2013 to solve a growing problem: individuals and their personal technology were facing sophisticated digital threats with no clear path to protection. Brad saw what others missed—cybersecurity wasn’t just an IT issue; it was a personal one. His mission ever since has been to provide real people with the same level of protection once reserved for corporations and governments—without the complexity, invasiveness, or loss of control.

A Vision Rooted in Autonomy and Resilience
Brad’s work is driven by a belief that cybersecurity is essential to personal safety, privacy, and freedom in the Digital Age. He advocates for digital autonomy—empowering individuals to own, control, and protect their technology and information across every device, location, and network they use.
As a speaker, writer, and advisor, Brad makes the complex simple. He’s helped thousands of people—from families to executives to professional advisors—understand digital risk and take practical steps to stay protected. His approach blends enterprise-grade tools, concierge-level service, and an unwavering focus on people over infrastructure.
With decades of experience in high-trust environments—including a career on Wall Street and executive leadership in wealth management—Brad brings a uniquely human-centered lens to cybersecurity. He’s led TDS from its founding through a decade of growth, innovation, and real-world impact, serving private clients and organizations around the globe.
