Not So Contained: When Container Isolation Is Just an Illusion | A Brand Story with Emily Long from Edera | An On Location RSAC Conference 2025 Brand Story

Kubernetes revolutionized the way software is built, deployed, and managed, offering engineers unprecedented agility and portability. But as Edera co-founder and CEO Emily Long shares, the speed and flexibility of containerization came with overlooked tradeoffs—especially in security. What started as a developer-driven movement to accelerate software delivery has now left security and infrastructure teams scrambling to contain risks that were never part of Kubernetes’ original design.

Emily outlines a critical flaw: Kubernetes wasn’t built for multi-tenancy. As a result, shared kernels across workloads—whether across customers or internal environments—introduce lateral movement risks. In her words, “A container isn’t real—it’s just a set of processes.” And when containers share a kernel, a single exploit can become a system-wide threat.

Edera addresses this gap by rethinking how containers are run—not rebuilt. Drawing from hypervisor tech like Xen and modernizing it with memory-safe Rust, Edera creates isolated “zones” for containers that enforce true separation without the overhead and complexity of traditional virtual machines. This isolation doesn’t disrupt developer workflows, integrates easily at the infrastructure layer, and doesn’t require retraining or restructuring CI/CD pipelines. It’s secure by design, without compromising performance or portability.

The impact is significant. Infrastructure teams gain the ability to enforce security policies without sacrificing cost efficiency. Developers keep their flow. And security professionals get something rare in today’s ecosystem: true prevention. Instead of chasing billions of alerts and layering multiple observability tools in hopes of finding the needle in the haystack, teams using Edera can reduce the noise and gain context that actually matters.

Emily also touches on the future—including the role of AI and “vibe coding,” and why true infrastructure-level security is essential as code generation becomes more automated and complex. With GPU security on their radar and a hardware-agnostic architecture, Edera is preparing not just for today’s container sprawl, but tomorrow’s AI-powered compute environments.

This is more than a product pitch—it’s a reframing of how we define and implement security at the container level. The full conversation reveals what’s possible when performance, portability, and protection are no longer at odds.
