Retired Brigadier General Joe Stringham "rose through the ranks in US Army Special Forces and has been assigned to foreign governments as a security representative for the Joint Chiefs of Staff. Post retirement he has developed security systems and teams around the world to support governments and industry." 
Stringham leads the "in-house expertise" for Alutiiq LLC, a "wholly owned subsidary of the Afognak Native Corporation, an Alaska Native corporation formed under the Alaska Native Claims Settlement Act," to "properly analyze and detect vulnerabilities, recommend sound approaches to eliminate them, and real world savvy to know which approaches really work." The Alutiiq "team also consists of former military and CIA security specialists. General Stringham and his team have the real world experience to know how to help security personnel and avoid the pitfalls of overly complex, failure/fault prone equipment, and ensure that systems are integrated to provide a seamless operating environment."
