A Different Kind of
Security Firm

👮
Real Law Enforcement Background
As an active Sergeant with 10+ years, Byron has worked real threat scenarios — not simulated ones. That shapes every assessment.
🔒
Physical + Cyber in One Visit
Most firms do one or the other. We assess your locks and your router in the same engagement — because attackers don't specialize.
📋
Plain-English Reports
No jargon PDFs. Every report is written for humans — prioritized findings, photos, and clear next steps you can actually follow.
📍
Tennessee-Based & Local
We're not a national firm sending contractors. Byron shows up personally — someone with skin in the game and roots in the community.

Byron Sexton
Principal Consultant

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.
