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.

See more about how Tetragon is using eBPF.

Getting started

Refer to the official documentation of Tetragon.

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

• Try Tetragon on Kubernetes
• Try Tetragon on Linux
• Deploy Tetragon
• Install the Tetra CLI

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:
   • 🌏 network observability
   • 📂 filename access
   • 🔑 credentials monitoring
   • 🔓 privileged execution
