Justin Garrison
Field CTO @ Sidero Labs
10.00 - 10.40, Mainstage
The “starter cluster” has evolved from the simple days of kube-up to powering the largest platforms in the world. Kubernetes is the application interface developers expect, but it doesn’t fit everywhere. Justin has spent years trying to meet that challenge. He’s built some of the smallest and largest clusters in the world using old, new, and custom-built hardware. He’ll share lessons learned from putting Kubernetes into places it wasn’t originally designed to run—and how those experiences are shaping a simpler path forward with Talos Linux.
Justin serves as Field CTO at Sidero Labs and hosts the Fork Around and Find Out podcast. He has been called the Steven Spielberg of Cloud Native and the Bill Nye of tech. His career includes contributions to Oscar-winning films, the Disney+ streaming platform, and Amazon EKS. In his free time, Justin enjoys building modern-retro computers and watching Moana.
Shantanu Gattani
SVP, Product @ Sysdig
11.00 - 11.40, Mainstage
For over a decade, cloud security has been a dashboard discipline. That assumption is breaking, and not because a vendor decided so.
Like their engineering counterparts, the most AI-mature security teams are rebuilding their workflows around the coding agent as the control surface: from posture and identity to runtime data through MCP, defining policy in natural language, and running end-to-end remediation from signal to merged pull request without opening a UI. Enter: Headless cloud security.
This keynote is a field report on that shift. Attendees will explore what these security teams are building, what holds up in production, where it breaks, and what it takes for a headless security platform to meet AI-mature teams where they already work.
With headless cloud security, the dashboard does not disappear, but it does stop being the destination. Keynote attendees leave with a way to evaluate the same evolution in their own program.
Shantanu Gattani is the SVP, Product at Sysdig, where he leads the development of cloud security solutions. With over 15 years in the security industry, he has a proven track record of creating and maintaining products that fill necessary market gaps. Before Sysdig, Shantanu held senior product management roles at Tenable and Accurics, focusing on cloud security and exposure management.

William Rizzo
Global Field CTO @ Mirantis + Kairos Maintainer
13.30 - 14.05, Mainstage
Most inference scenarios assume a datacenter: gigawatts of power, fat pipes, and an operator who can SSH into any node. The edge breaks all three. You're serving models on hardware in a factory floor, retail site, vehicle or remote facility, the link drops for hours at a time, and "just patch the node" means dispatching a human.
This talk shows how an immutable, image-based operating system turns those constraints into guarantees. We'll walk through serving an LLM on read-only edge nodes: packaging model + runtime + GPU drivers into atomically-updated images, doing A/B upgrades and rollbacks with no remote shell, and keeping inference healthy across disconnected fleets.
You'll leave with a concrete reference architecture, the failure modes we hit in production across several nodes and sites, and an honest account of where edge inference still hurts. Built entirely on CNCF and open source projects.
William is a CNCF Ambassador and Linkerd Ambassador currently working at Mirantis as Global Field CTO. He’s focused on helping customers designing, building, and running their initiatives on Edge, AI and Platform Engineering. He wore many hats in the IT world, Engineering, Pre-Post sales, Product Owner and Consulting. from HPC, Storage to Distributed Systems.
William enjoys volunteering in several Cloud Native groups and organizing the KCD Netherlands events.
Merijn Keppel
Principal Consultant @TrueFullstaq
14.05 - 14.40, Mainstage
Earlier this year at KubeCon EU, a wild live demo appeared: we deployed and upgraded a Talos Kubernetes cluster in a completely air-gapped environment using Zarf, going from bare metal to a running cluster with zero internet connectivity, then upgrading it live on stage. Critical hit, crowd loved it. What we didn't get to show was the training montage behind the scenes: everything that had to go right to make that "magic" actually work.
This time, I'm revealing the moveset. In this session, I'll break down the real automation driving that demo, including how Talos Linux gives you a rock-solid, predictable OS built specifically for Kubernetes, and how Zarf bundles the OS, Kubernetes itself, and your applications into a single portable package you can deploy anywhere. I'll dig into the tooling that evolved "spin up a cluster with zero connectivity" from a flashy one-off into something repeatable and reliable, and where TrueFullstaq is taking this "magic" component next.
Merijn is Principal Consultant at TrueFullstaq, focused on declarative infrastructure such as NixOS, Talos Linux, and Zarf, with a particular interest in reproducibility challenges in disconnected and air-gapped systems.

Kris Budde
Product Owner @ STACKIT Edge Cloud
15.55 - 16.30, Mainstage
(A duo talk with Fabian Schmitt)
Building a platform sounds right until every team builds its own. At one of the world’s largest retailers, one platform didn’t fit all, but many siloed platforms did not scale. Different products, constraints, and experience levels drove divergence.
In this talk, we show how we addressed this by building an Open Source Platform Framework not as a rigid product, but as a shared foundation. It allows teams to own their platforms while sharing common practices, from standard cloud setups to 15,000+ edge locations.
I’m an infrastructure enthusiast turned Product Owner, with a deep background in SRE, virtualization, and Kubernetes. Today, I drive the product strategy for STACKIT Edge Cloud at Schwarz Digits, building the next generation of edge infrastructure management for modern cloud-native applications

Alessandro Lo Prete
Threat Detection Engineer @ Sysdig
14.05 - 14.40, Security stage
In 2026, the Sysdig Threat Research Team started observing an AI operator targeting popular AI infrastructure with a fully agentic ransomware campaign. We call it JADEPUFFER, and it is the clearest case we have of what an autonomous attacker does to the infrastructure you run every day.
In this talk, we'll show how agentic threat actors are changing the security landscape. We'll walk through the intrusion the way it happened, from CVE exploitation to ransomware deployment, and see how JADEPUFFER recovered from its own failures and ran dozens of operations a minute in parallel, faster than any human could keep up with. Finally, we'll look at how this shifts the security baseline that defenders and builders have to meet, given how easily a campaign like this can now be automated.
You will leave with the anatomy of an agentic intrusion and a clearer sense of what is changing, and what is not. The tooling is new and getting cheaper, but the doors it walked through are the same ones we have always been responsible for closing.
Alessandro Lo Prete is a Threat Detection Engineer at the Sysdig Threat Research Team, specializing in cloud security and Linux runtime detection. His current research explores integrating AI into defensive detection workflows and detecting agentic threats. Previously, he collaborated with the European Space Agency (ESA) on time-series anomaly detection for Delay Tolerant Networks as part of his MSc thesis.
Daniëlle Wagemakers
Lead Cybersecurity Technology Specialist @ Sogeti
15.15 - 15.55, Security stage
Somewhere in the last few years, platform teams became security teams. They run the admission controllers, patch the base images, own the pipeline everything ships through, and now review the code AI agents write. Most never applied for the job.
This panel brings engineering and security leaders from large enterprises on stage to compare notes on how that shift is going: which open source security tools earned a permanent place in their stacks, what changed in how they secure running workloads once AI coding agents started committing to production, where they draw the line between platform work and security work, and how they keep shipping fast while the security surface grows.
You'll hear how teams like yours split the work today, and what they would change if they were starting over.
Daniëlle is a Lead Cybersecurity Technology Specialist, at Sogeti. There, she specializes in threat modeling, coaches teams through their threat modeling journeys and security in DevOps, and advocates for the responsible use of GenAI. You might also recognize Daniëlle from her other roles: she is on the organizing team of WICCON, one of the Digitale Dolle Minas, and is a speaker at various events on threat modeling, inclusion, and consent. If she's not doing any of that, she's probably in a theater somewhere enjoying a musical.

Marcel Claassen
Principal Solutions Engineer @ Sysdig
15.55 - 16.25, Security stage
Agentic attacks run end to end with no human at the keyboard, and a defense that waits for someone to read an alert has already been lost.
In this session, Marcel replays one of these attacks live against a real cluster and lets Falco-powered threat detection answer at the same speed. You'll watch the eBPF event stream show what the kernel sees, detection rules fire as the intrusion unfolds, alerts land in the channels your team already pages on, and automated responses kill the compromised workload before a human could have read the message. This is the same engine behind Sysdig Secure's runtime detection, hardened by a decade of community engineering and production use at more than 9,000 organizations.
You'll leave knowing what Falco catches against the newest class of attacker, and what it looks like to respond at the speed the attack demands.
