Defender Fridays: A look back

For 115 weeks, Defender Fridays brought together practitioners from across the InfoSec world for candid, unscripted conversations about the defensive side of security. No slide decks, no sales pitches — just a half hour of honest dialogue on threat hunting, incident response, detection engineering, security operations, and everything in between.

Organized by the LimaCharlie team and created by Eric Capuano, the series was built around a simple premise: the people doing this work have hard-won knowledge worth sharing. Week after week, guests showed up and spoke openly about what they'd built, what had broken, and what they'd learned along the way. We're grateful to every guest, host, and viewer who was part of it.

A few worth revisiting:

Johan Berggren, Staff Security Engineer at Google, walked through OpenRelik, an open source platform built for collaborative digital forensic investigations. A practical look at how tooling can change the way DFIR teams work together.

Philip Martin, CSO at Coinbase, got into the specific security challenges that come with running a crypto exchange and the strategies his team developed protecting billions in digital assets. A rare window into security at that scale.

For the final episode, Eric Capuano, creator of Defender Fridays and co-founder of Digital Defense Institute, came back to close out the series with a look at how he's actually building and running agentic workflows in the SOC today.
