    Why Contributing to Open Source Matters for the Mission

    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.  Key Quote: “ When you try to take something that is not airgap friendly and make it airgap friendly, you quickly find out that you made a lot of assumptions about how this thing would be used and where, and kind of the underlying infrastructure and when you try to work back for them that it's, it, it's difficult. It's not something you can't overcome. It's not insurmountable, but it is difficult. But you also find out that there's just a lot of areas for. Resiliency that you didn't also plan for, that applied to connected environments. And so this is where I've kind of been diving into this more and more lately to try and to describe, and build some knowledge to around why this is important for kind of building any application today. It may be a little niche to go to the extreme of air gap, but I believe like there's still some of these underlying cloud native fundamentals that is like, if you start with the ability for knowing how your architecture adapts to varying levels of connectivity, then you're probably building a stronger, more resilient system overall.” Brandt KellerTime Stamps: (03:19) The Defense Sector and Career Path (06:15) Becoming a Cloud Native Computing Foundation Ambassador (09:48) Open Source Contributions and the Challenges (14:14) Government and the lack of Open Source (32:53) Kubernetes and Foreign Contributions (37:24) The Importance of Air Gap in Cloud Native Tools (53:16) Lightning Round   Links: Connect with Brandt Keller Connect with Rebecca Lively Learn More About Defense Unicorns

    Shipping Software Faster and Safer with Pepr

    On this episode of The Defense Unicorns Podcast, host Rebecca Lively chats with Case Wylie, Software Engineering Lead, about building security-minded software that keeps up with developer velocity. From his early days at Red Hat to architecting open-source tools at Defense Unicorns, Case shares how Pepr—a TypeScript-based operator framework—is redefining how Kubernetes clusters are secured and managed in airgapped environments. It’s not just about enforcing policy; it’s about enabling developers to move faster, safer, and smarter. Through real-world metaphors (ever been to a nightclub with strict bouncers?), Case breaks down the roles of admission controllers, operator frameworks, and how Pepr works seamlessly with GitOps without adding friction. He explains why Pepr isn’t just a tool, but part of a broader movement to standardize security postures, reduce configuration drift, and empower app teams to focus on delivering real value. With a human-first API and open-source DNA, Pepr is built to be accessible to all, not just Kubernetes power users. If you’re curious about what it takes to scale secure software in complex, mission-critical environments—or just want a fresh, practical take on DevSecOps—this episode delivers. Case also shares his philosophy on open-source collaboration and what it means to build tools that truly stand the test of scale and scrutiny. Key Quote: “Pepr will always be open source and the reason why it's open source is because frankly, open source software, when your software is open source, you expose the application or the software or the platform, whatever it is to exponentially more eyes and more eyes over time and then more people start adopting it and using it and saying like, ‘Hey, you know what? I do have this simple thing I always have to do in my cluster. Maybe I try Pepr for that.’ Right? And then they do it with a simple task, and then they say, ‘Hey, you know what? It would be great if Pepr could do this thing. And they put in a feature request. Then we develop that feature request, or they develop it, and they submit a PR to Pepr. And now Pepr as a whole is better because now you're using it. I'm using it. They're using it. The more people that use it, the better.” Case WylieTime Stamps: (02:44) Introduction to UDS and Pepr (05:59) The Importance of Air-Gapped Environments (11:40) Understanding Kubernetes Admission Control (16:05) Comparing Pepr with Other Tools (22:00) Why Pepr Uses TypeScript (34:03) The Benefits of Open Source for Pepr (43:31) Lightning Round Links: Connect with Casey Wylie Connect with Rebecca Lively Learn More About Defense Unicorns

    Why DIU Ruined Wayne Starr in the Best Way

    On this episode of The Defense Unicorns Podcast, we’re not just talking about writing code—we’re talking about what happens when you try to change the culture of software inside the Department of Defense. From flying to Qatar to debug mission-critical planning tools to reflashing smart lightbulbs with open-source firmware, Wayne Starr has done it all. Host Rebecca Lively sits down with Wayne, a Unicorn Engineer at Defense Unicorns,  to unpack what it takes to deliver secure, user-centered software in one of the world’s most complex environments. Wayne shares how his early career at DIU “ruined” him—in the best possible way—by showing what was possible when bureaucratic blockers are set aside and software teams are trusted to deliver. He dives into real DevSecOps wins and war stories, including a mission-planning app that saved hours of planner time and real dollars in fuel. Along the way, he reflects on the absurdity of battles over office headsets, the power of printing MP3s on paper, and how open source gives individuals more control over their technology. If you’ve ever tried to navigate the maze of government compliance, or if you’re just wondering what DevSecOps looks like when it’s done right, Wayne’s story offers a rare behind-the-scenes look. From tactical impact to philosophical reflections, this conversation covers what it means to ship software that matters—and why knowing the rules better than anyone else is sometimes the only way to change the game. Key Quote Options: “  I want to control technology. I don't want technology to control me. If it's closed-source software, it could suddenly require a subscription at some point, it could be connected to the cloud, and who knows what's happening with the data, who knows where that's going. And so I try to pull as much back as I can to things that I can control and that I can monitor and use.” Wayne StarrTime Stamps: (00:49) First Assignment at Defense Innovation Unit (04:28) Skepticism and Acceptance from Users (12:16) Open Source Software Journey (29:55) Creating ZARF (39:23) Other Notable Open Source Projects: Pepper and Lula (43:31) Lightning Round Links: Connect with Wayne Starr Connect with Rebecca Lively Learn More About Defense Unicorns

    Breaking the Myths of DevSecOps

    On this episode of The Defense Unicorns Podcast, the question isn’t just how to deliver software—it’s how to do it faster, safer, and smarter. According to Bryan Finster Distinguished Engineer at Defense Unicorns, the answer isn’t in rigid frameworks or bloated processes but in embracing continuous delivery, shortening feedback loops, and eliminating the bureaucratic roadblocks that hold teams back. Host Rebecca Lively sits down with Bryan to debunk DevSecOps’ myths, tackle the frustrations of “Agile theater,” and explore why real software success comes from a culture of ownership, not just following a set of rules. Bryan makes a compelling case that rigid processes, review boards, and bureaucratic bottlenecks don’t make software safer—they make it fragile. He argues that adaptability is the real key to security, and that organizations clinging to outdated waterfall-style contracts are setting themselves up for failure. Drawing on experiences from Walmart’s supply chain to government defense systems, he explains how fostering a culture of ownership, feedback, and accountability leads to better outcomes—not just for users, but for the engineers who build the systems. If you’re tired of buzzwords and top-down mandates that miss the mark, this conversation will hit home. Bryan isn’t just here to talk about DevSecOps—he’s here to challenge the way you think about software, leadership, and even history. Whether you want to deliver better software or just hear an unfiltered take on why Agile often fails in practice, this episode is worth a listen. Key Quote: “ The goal we have is number one, I need to be able to respond to the realities of what's happening in production as quickly as possible safely. I don't want to be making up ways to. Make change, I don't want to be cowboying change in when something's going wrong in production, either with security breach or functional problems or whatever it is, then I don't want to be throwing gasoline on a fire  at three o'clock in the morning. I need to be able to recover from what's currently occurring as quickly and safely as possible. So operational responsiveness is key. The other part is, if I'm building something new, software development is not the same as building a car.  Unless you think of it as designing the car we're going to build. We're prototyping everything all the time. And the bigger the thing is that we deliver.  The more wrong is in that prototype. And so it's not about speed. It's about feedback.” Bryan FinsterTime Stamps: (01:39) Balancing Speed and Safety in DevOps (03:53) The Role of Feedback in Software Development (12:35) The Power of Feedback and Continuous Improvement (18:35) Understanding Conway's Law (23:55) Building a Strong Engineering Community (28:26) DevOps and Quality Assurance (33:48) Being Agile in High-Risk Environments (40:13) Lightning Round Links: Connect with Bryan Finster Connect with Rebecca Lively Learn More About Defense Unicorns

    Keeping Open Source Software Secure with Eddie Zaneski

    This week on, Defense Unicorns Podcast we welcome Eddie Zaneski, the tech lead for open source here at Defense Unicorns, who takes us through his fascinating career journey from aspiring math teacher to a key player in the tech industry. Eddie shares his experiences transitioning into computer science, his passion for developer relations, and his significant contributions to the Kubernetes project. We dive into the evolution of software deployment, from bare metal servers to virtual machines and containers, and how Kubernetes has become essential in managing large-scale containerized applications. Eddie also reflects on his time at DigitalOcean, Amazon, and ChainGuard, highlighting his work on software supply chain security projects like Protobomb and Sigstore. Our conversation then turns to the security of open-source communities, challenging the misconception that open-source software is less secure than its closed-source counterparts. Eddie discusses the advantages of transparency in open source, using the XZ library's recent security breach as a case study to emphasize the importance of trust and identity verification. We also explore the potential for similar vulnerabilities in closed-source projects and the growing importance of supply chain security measures, including building integrity and software bills of materials (SBOM). The episode concludes with a thought-provoking discussion on the benefits of transparency in open source and whether proprietary software incidents would be as openly shared or understood. Eddie shares his enthusiasm for leveraging government funding to support open-source projects. He expresses his excitement about engaging with soldiers, airmen, and guardians to understand their challenges and explore open-source solutions. We also touch on innovative tools for air-gapped environments, like Zarf, and their applications across various industries. Listen in as Eddie recounts his experiences at Bravo hackathons, the unique challenges faced by developers in constrained environments, and offers valuable career advice for those passionate about open source and software development. Key Quote “There's lots of misconceptions and I'm sure you and I can talk about all of them. One of the big ones is, just. It's less secure, right? that's a massive myth. Open source security is less secure because all the code is in the open and everyone can go find the holes and generally quite the opposite actually, because the code is in the open, everyone can do their own audits and everyone can see what's happening under the covers of the magic box that you usually can't peer into with proprietary software. We have entire teams of like security. So the Kubernetes project is divided up into special interest groups or SIGs. So we have SIGs for security, we have a product security council and committee that is the incident response people for when there is a new CVE or a bug found, and all sorts of different types of things that are just tailored around security.” -Eddie Zaneski Time Stamps: (00:02) Kubernetes and Open Source Evolution (08:17) Security in Open Source Communities (20:43) Software Bill of Materials for Cybersecurity (24:04) Exploring Defense Unicorns and Open Source (31:43) Navigating Careers in Open Source (42:25) Breaking Barriers in Defense Innovation (46:42) Collaborating for Defense Open Source Links Connect with Eddie
