Byron Sexton is an active Law Enforcement Sergeant with over a decade of real-world threat response experience. After recognizing that the families and businesses he protected faced serious digital vulnerabilities alongside physical ones, he pursued certified cybersecurity training — earning CompTIA Security+, A+, ITF+, Cisco Ethical Hacker, and placing as a SkillsUSA Cybersecurity State Champion.
Sentinel Shield Sec was founded on a simple observation: physical security firms don't understand networks, and cybersecurity firms don't understand physical entry points. Attackers use both. Byron bridges that gap — delivering the only combined physical and digital security assessment in Tennessee.
Every client gets Byron personally — not a subcontractor. Every report is written in plain English. And every engagement is backed by real-world experience from someone who has responded to actual threats, not just simulated ones.
