Five Decades of Trusted Protection

Built on Stability and Experience

Since 1972, Fleenor Security has protected the Tri-Cities’ most trusted institutions—hospitals, universities, manufacturing facilities, and residential properties. Our NICET-certified consultants conduct comprehensive vulnerability assessments specific to your property and location, analyzing operational workflows and regional security challenges that distant competitors overlook. You receive strategic security infrastructure that protects what matters most and adapts to evolving needs.

Growing Stronger, Serving Smarter

The Tri-Cities region’s growth demands more sophisticated security solutions. Fleenor Security has evolved alongside this community for five decades—from local alarm company to full-service integrator offering fire detection, video surveillance, access control, and data networking. Our second-generation ownership delivers enterprise capability with local commitment and personal relationships.

“I have been extremely pleased with Fleenor Security for 2.5 years. Having had other security systems in other states, it was a unique and happy experience to find one that is local, with real people that will work with you 24/7.”

“Love Fleenor Security! They completed all of the necessary installations at our house, and we really find comfort in knowing that we will be alerted if anything amiss happens when we are not home or that someone will reach out to help when things run awry when we are here. Overall, it’s a wonderful service to have in a world where uncertainty and feelings of insecurity abound. Thank you Fleenor for giving us some peace of mind!

“The installers were very polite and careful. We felt very comfortable having them in our home, and they left their work areas cleaner than they found them.”

B.H., ErwinResidential April 1, 2026

“We have used Fleenor Security with two different homes over the past years. The Fleenor team has always been great to work with. They are most knowledgeable and professional in all aspects of the business.”

Rene H.Residential May 1, 2023

Fleenor Security Systems has provided the best alarm service, that I have ever had. Their service is far beyond the national advertised security companies. When you have an alarm, or you are having a system problem, you are talking to a local well trained person, located in East Tennessee, not a call center in some far reach location.”

Neal J.Residential November 1, 2019

“Fleenor and Sewell & Company Construction, Inc. Have had a very long term relationship, dating back into the 1990’s. Fleenor provides security services and monitoring of our residential and commercial projects both during the construction phase and after the projects are turned over to the owners. They provide exceptional service to us and to our clients over the phone and physically on the jobsites.”
