The No Password Required podcast is dedicated to introducing and celebrating the practitioners, leaders, researchers, and individuals who are shaping the cybersecurity industry. Join us for an in-depth conversation that explores our guests' personalities, expertise, and the path that led them into cybersecurity. The team also discusses current cyber threats and readiness tips for security professionals and business leaders alike. On this episode, we sit down with Rob Allen, chief marketing officer at ThreatLocker, live from the 2024 Sunshine Cyber Conference. From his early days “locked” in an IT closet to his current role in the C-suite, Rob’s journey is one of curiosity, adaptation, and a passion for cybersecurity. At ThreatLocker, he takes customer ideas and use cases and transforms them into solutions for organizations of all sizes. Rob shares why businesses shouldn’t fear the “deny by default” approach, explaining how the zero-trust mindset is essential in today’s threat landscape. He also discusses with hosts Jack Clabby of Carlton Fields and Kayley Melton, director of strategic initiatives at the Cognitive Security Institute and the Bob Ross of infosec, how media coverage often distorts public perception of cybersecurity by only highlighting major breaches and incidents. In the lifestyle polygraph segment, Rob reveals his love for Apple products, why he wishes he could have met Steve Jobs, and his obsession with Buc-ee’s brisket sandwiches. He also shares a hilarious (and perhaps exaggerated) story about the Cyber Florida team “infiltrating” ThreatLocker and taking his backpack back to Tampa!
