Pixie is an eBPF-based observability platform for Kubernetes that can detect data exfiltration on the edge. Pixie's edge architecture involves a cloud control plane and Vizier data planes that are deployed to each cluster to collect and process data in-memory within each cluster. Pixie uses eBPF probes to trace protocols at the kernel level, covering all traffic with minimal overhead. This allows Pixie to detect potential data leaks by searching traffic patterns for sensitive data like credit cards or social security numbers that are egressing the Kubernetes cluster.
