Don't miss out! Join us at our next Flagship Conference: KubeCon + CloudNativeCon events in Amsterdam, The Netherlands (23-26 March, 2026). Connect with our current graduated, incubating, and sandbox projects as the community gathers to further the education and advancement of cloud native computing. Learn more at Confidential Observability on Kubernetes: Protecting Telemetry End-to-End - Jitendra Singh, Microsoft Kubernetes observability tools, like Fluent Bit, OpenTelemetry, and Loki, provide deep visibility, but they also handle sensitive data: user identifiers, tokens, and internal service metadata. Even with encryption at rest and in transit, telemetry data is often exposed during collection and processing. In this lightning talk, we’ll show how to secure observability pipelines on Kubernetes using confidential computing-enabled nodes. We demonstrate how observability components (e.g., Fluent Bit, OpenTelemetry Collector, Loki) can run inside hardware-isolated Kubernetes nodes, ensuring that telemetry data is encrypted at the source and only processed by trusted, attested workloads. Attendees will learn a practical, zero-intrusion design that combines Kubernetes-native observability tools with confidential compute infrastructure to deliver end-to-end encrypted, trusted observability, ideal for regulated workloads in finance, healthcare, and government.
