Cilium’s new Tetragon component enables powerful real-time, eBPF-based Security Observability and Runtime Enforcement.

Tetragon detects and is able to react to security-significant events, such as

  • Process execution events
  • System call activity
  • I/O activity including network & file access

When used in a Kubernetes environment, Tetragon is Kubernetes-aware - that is, it understands Kubernetes identities such as namespaces, pods and so on - so that security event detection can be configured in relation to individual workloads.

Getting started

Refer to the official documentation of Tetragon.

To get started with Tetragon, take a look at the getting started guides to:

Tetragon is able to observe critical hooks in the kernel through its sensors and generates events enriched with Linux and Kubernetes metadata:

  1. Process lifecycle: generating process_exec and process_exit events by default, enabling full process lifecycle observability. Learn more about these events on the process lifecycle use case page.
  2. Generic tracing: generating process_kprobe, process_tracepoint and process_uprobe events for more advanced and custom use cases. Learn more about these events on the TracingPolicy concept page and discover multiple use cases like:
