Defense Unicorns, A Podcast · 2025-05-19 · 60 min
On this episode of The Defense Unicorns Podcast, host Rebecca Lively sits down with Brandt Keller, software engineer and CNCF ambassador, to explore what happens when a former Marine brings his frontline mindset to DevSecOps. Brandt’s story is one of relentless problem-solving, especially in disconnected, air-gapped environments where “cloud-native” has to mean something entirely different. Brandt unpacks how open source can be both a lifeline and a liability in government systems, and why just consuming it isn’t enough - real security means showing up, contributing, and understanding what’s under the hood. He shares his perspective on trust, transparency, and why the U.S. government’s lack of contribution to critical tools like Kubernetes might be the real risk. The conversation also explores the cultural shift required to embrace open ecosystems in highly regulated spaces. From debates over supply chain security and SBOMs to the practical challenges of deploying software in classified settings, this episode offers a grounded, behind-the-scenes look at what it takes to build tools that truly work at the tactical edge.
