SENTRYSIX® International, LLC, is a professional security and risk management firm. We are owned, operated and managed by U.S. Military veterans, to include special operations personnel, and law enforcement experts. Our areas of expertise include threat management, counter-terrorism solutions, logistics, investigations and intelligence operations. 

Our primary focus has been to provide an unmatched level of professionalism, and provide highly experienced personnel in the private sector. The standards for private security and hiring practices have been set so low, that hiring many of the larger security companies today is simply a waste of time, money and resources. We are here to change the face of private security and raise the bar. We have raised the bar, and set the standard for others to follow.

The services we offer are tailored and focused on counter-terrorism and public safety operations. This includes the protection of critical infrastructures, our nations border against threats from transnational criminal organizations such as weapons, narcotics and human smuggling, and to ensure public safety in and around our communities.

Our firm was organized with an intended purpose of providing the highest quality of service and provide, through employment, only the highest caliber of individuals in the industry to our clients. By doing this, we are able to surpass any other firm in the level of experience, expertise, professionalism, superior protection, provided training and customer service. The world we live in today is completely different than the world we lived in fifty years, twenty, ten or even a year ago. The threats we face today from domestic criminal activity to transnational terror organizations, is on the rise and the need for trusted protection has never been greater.
