Our Mission Our mission is to partner with our clients in helping law enforcement bring a greater percentage of criminals to justice through the delivery of the highest quality security equipment, installation and service. NASS strives to be large enough to service multi-branch institutions and large corporations. We maintain a level of sophistication and expertise that rivals even the largest national security companies. At the same time, we wish to remain small enough so that we never compromise the highest level of personalized service. Thus, we believe no physical security company, large or small, matches the combination of expertise and attentiveness that we provide.
