Corey Quinn sits down with Avery Pennarun, co-founder and CEO of Tailscale, for a deep dive into how the company is reinventing networking for the modern era. From finally making VPNs behave the way they should to tackling AI security with zero-click authentication, Avery shares candid insights on building infrastructure people actually love using, and love talking about.

They get into everything: surviving 100% year-over-year growth, why running on two tailnets at once is pure chaos, and how Tailscale makes “secure by default” feel effortless. Plus, they dig into why FreeBSD firewalls needed some tough love, the uncomfortable truth behind POCs, and even the surprisingly useful trick of turning your Apple TV into an exit node.
