Cilium is an open source, cloud native solution for providing, securing, and observing network connectivity between workloads, fueled by the revolutionary Kernel technology eBPF.
Cilium is used to provide and transparently secure network connectivity and load balancing between application workloads such as application containers, processes, or VMs. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC, and Kafka. Cilium is a part of the Cloud Native Computing Foundation and is their most advanced and widely used CNI for Kubernetes. Check out the Getting Started Guides to try it out.
Cilium has hundreds of adopters around the world including Bell Canada, Capital One, Google, The New York Times, and Yahoo. If you are using Cilium, add yourself to the list today!
Hubble is a fully distributed networking and security observability platform for cloud native workloads. It is built on top of Cilium and eBPF to enable deep visibility into the communication and behavior of services as well as the networking infrastructure in a completely transparent manner. Hubble helps teams understand service dependencies and communication maps, operational monitoring and alerting, application monitoring, and security observability.
Tetragon enables powerful realtime, 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 and pods - so that security event detection can be configured for specific individual workloads.
