Quality Guard Services

Our Business is Protecting Your Business​

Who We Are

Horizon Security, locally owned & operated, is a distinguished provider of premium contract security services throughout Northeast Texas. Based in Dallas, the culture of Horizon Security is both client and employee focused.

Supporting and winning our “internal” customer – security officers, is instrumental in providing outstanding service to our “external” customers, our clients. Our employees are not guards – they are security ambassadors. One of our unique service features that sets us apart from other companies and exhibits our passion for world class service is that top management personally interviews, hires and orients each new security officer to our company’s culture. The same management team trains those employees on our client accounts, to ensure a consistently high level of service..

We are dedicated to serving our clients with the upmost professionalism. This means well trained officers AND responsive local management, experienced in solving issues that arise in day to day operations. This is our quality pledge that is the heart of the service we provide. Regardless of industry or type, no two security contracts are the same. The Horizon Difference means working together with our clients on their individual needs and implementing service to those needs.

With a senior management team that has over 45 years of experience in Security Service Management, Law Enforcement, Investigations, business management.  Our motto is simple: 

“Horizon Security, Where Quality Guard Service Meets Your Expectation.”
