Tune in to the Outside-IN podcast to hear Charles Riddervold, National Director of Operations and Proposal Strategy, who began his career in mail security nearly 40 years ago while screening packages for soldiers in the Army, discuss why the modern corporate mailroom is a crucial vulnerability and a potential entry point for real threats. Discover why mail security has become a massive priority, driven by the immediate danger to people from letter bombs and white powder scares, such as the mid-2010s ricin attack that cost the Department of Justice almost $7 million, as well as newer threats like industrial chemicals and drugs such as Fentanyl. This episode explores the multi-layered process of mail screening, detailing methods that range from simple visual inspection and basic X-raying to deep chemical, biological (CBRNE), and radiological screening, including the logistics of using costly onsite negative pressure air rooms or managing the typical 24-hour lag of offsite screening. Learn how IST leverages advanced technologies like Ray Secure CT scanners and "Smart Tech," which connects local X-ray operators to remote EOD experts, to secure high-risk verticals like healthcare and government contractors. The discussion also covers critical contingency planning, the fact that 90% of mail-borne threats typically arrive via USPS rather than commercial carriers, and the essential creativity required in designing a tailored security plan, focusing on asking clients the pivotal question, "What are you afraid of?" to ensure effective protection.
