ASI Has Launched a New Brand Identity

American Security and Investigations (ASI) is launching a new corporate image on May 1, 2021. ASI has carried the current corporate image since our inception in 1976 and we believe this updated branding better represents who we have become as an organization. Since our origins as a Minnesota patrol company, we have become one of the largest integrated security providers in the United States, combining traditional guarding services with advanced technologies to create customizable solutions for any facility infrastructure. As we set out on this brand journey, we wanted to create a new look that would positively reflect on our history and position us for the future. We want our corporate image to visibly and proudly identify ASI for who we are today: a modern, professional, strategic thought leader in our industry.
