David always has great topics and guests. I listen to other security podcasts where there’s only one person speaking…man they’re boring! Not David’s! Always engaging!

This podcast is by far my favorite infosec podcast. The in-depth knowledge we are party to from the industry’s best is so invaluable. What I like most is that it gives context to the decisions that shape the workday of those of us on the lower tiers. It also helps shape our thought process into how the work we do everyday affects the arching business decisions that keep our companies at the forefront. For anyone in infuse that has an aspiration to one day be at the top, this podcast is for you.
