Tetragon vs Tracee

Tetragon is a Kubernetes-aware security observability and runtime enforcement tool for Linux, container, and Kubernetes workloads. It uses eBPF to monitor activity, filter events, and enforce policies in the kernel in real time. Process reports can include executed binaries, command-line arguments, user IDs, parent processes, and start times. Tetragon also monitors file access and changes, and can block unauthorized file operations at the kernel level. Kubernetes policies can filter activity by namespace, pod labels, and container fields, with support for containerd and CRI-O. Network visibility ties events to processes and workloads and tracks connections, socket lifecycle, and bytes sent or received. The tool also monitors credential changes, kernel module activity, and eBPF program loads and interactions. Findings are available as JSON logs or through gRPC. Installation options include Helm on Kubernetes, released Linux packages, and a container image. Tetragon is a Cilium sub-project and a CNCF project, and is available as an open-source project with no paid plans listed.

Tracee is a free, open-source runtime security and observability tool for Linux. Using eBPF, it watches system calls, network activity, and file operations in real time, then emits events for behavior patterns that may indicate threats. Events can include process lineage, file paths, and network connections. Listed uses include security monitoring, compliance monitoring, troubleshooting, and forensic investigation. Tracee is designed to operate without code changes and lists low overhead, container awareness, and adjustable policies. Deployment options are an executable binary, a Docker Hub image, or a Helm chart in Aqua Security’s registry; the quickstart covers Kubernetes installation with that chart. Prometheus scraping is enabled by default, with metrics at :3366/metrics. It supports x86 and arm64 processors and documents long-term kernel versions 5.4, 5.10, 5.15, 6.2, and 6.5, while some distribution kernels may work. Instrumentation needs elevated capabilities, with privileged or root execution described as easiest. Tracee does not run directly on macOS.
