Security Now

Steve Gibson and Leo Laporte have been hosting Security Now together since 2005, making it one of the longest-running cybersecurity shows in existence. Every Tuesday, Gibson brings his encyclopedic knowledge of computer security to the TWiT network, breaking down the week's vulnerabilities, exploits, and patches in a level of technical detail you will not find on most other security podcasts. Gibson is a programmer and security researcher who created the first spyware detection tool (OptOut) back in the early 2000s. He has a gift for explaining complex technical concepts in a way that is thorough without being impenetrable. Leo Laporte plays the role of informed audience surrogate — asking the right questions, keeping the conversation grounded, and occasionally steering Gibson back when he goes deep into the weeds (which happens regularly, and fans love it). Episodes record live on Tuesdays at 4:30 PM Eastern and typically run over an hour. The show covers specific CVEs, patches from Microsoft and others, encryption news, protocol-level security topics, and broader trends like AI-generated malware and supply chain attacks. Nearly 2,000 people have rated it on Apple Podcasts, giving it a solid 4.6 stars. The show skews technical — if you want to understand how a vulnerability actually works at the code level, this is your podcast. Gibson's methodical approach and genuine passion for security are what keep listeners coming back after two decades.
