TL;DR: This week's episode features a long-time-coming discussion with Richard Bird discussing his book "Famous with 12 people", and the "influencer culture" in cybersecurity. It's an interesting discussion on how our industry works, and who makes it really turn.

TL;DR: This week's episode is all about a growing issue in CyberSecurity (and I'm sure it's there in other disciplines as well) - "specialization" or more to the point "over-specialization". Why is it a problem? Matt Shufeldt, a returning guest and friend of the pod, joins us to talk about it and suggests some ways we can avoid the giant iceberg we're careening into.

TL;DR: On this episode Amanda Berlin, Senior Product manager at Blumira, joins Jim and Rafal to talk about her career, the second edition of her book, and building products for SMBs that "don't suck". The unfortunate fact is that there aren't a lot of products designed for the unique challenges of companies that can't afford an army of security analysts, or consultants.
