Tetragon is a sub-project under Cillium and a proud CNCF project

eBPF-based Security Observability and Runtime Enforcement

Tetragon is a flexible Kubernetes-aware security observability and runtime enforcement tool that applies policy and filtering directly with eBPF, allowing for reduced observation overhead, tracking of any process, and real-time enforcement of policies.

Why Tetragon?

  • Minimal Overhead

    eBPF enables deep observability with low performance overhead mitigating risks without the latency introduced by user-space processing.

  • Kubernetes-Aware

    Tetragon extends Cilium's design by recognizing workload identities like namespace and pod metadata, surpassing traditional observability.

  • Simplified Operation

    Tetragon offers pre-defined policy libraries for rapid deployment and operational insight, reducing setup time and complexity at scale.

  • Kernel-level enforcement

    Tetragon blocks malicious activities at the kernel level, closing the window for exploitation without succumbing to TOCTOU attack vectors.

  • Real-time Policy Engine

    Synchronous monitoring, filtering, and enforcement are performed entirely within the kernel using eBPF.

  • Advanced Application Insights

    Tetragon goes beyond traditional monitoring, capturing events like process execution, network communications, and file access.

How does Tetragon work?

Tetragon monitors processes, syscalls, file and network activity in the kernel, correlating threats with network data to identify responsible binaries. It shares insights via JSON logs and a gRPC endpoint.

How to Install Tetragon?

  • Install Tetragon on Kubernetes Download via helm chart


                        helm repo add cilium https://helm.cilium.io
                        helm repo update
                        helm install tetragon cilium/tetragon -n kube-system
                        kubectl rollout status -n kube-system ds/tetragon -w
