Born in the aftermath of September 11, 2001, Zistos Corporation is a purpose-driven manufacturer founded by engineers Bob Levine and John Kennedy to help people see into dangerous spaces before entering them. From its Holbrook, New York facility, the company designs and assembles visual inspection systems for organizations whose work can put personnel at risk, with deployments in more than 25 countries. That original focus on protecting first responders still defines Zistos after more than two decades.
