The Cybersecurity Defenders Podcast

LimaCharlie

300 episodes

An accessible but technical podcast about cybersecurity and the people who keep the internet safe. The podcast is built as a series of segments: we will be looking back at the last couple of weeks in cybersecurity news, talking to different people in the industry about areas of their expertise, we're going to break apart some of the TTPs being used by adversaries, and we will even cover a little bit of hacker history.
