Cilium Tetragon: eBPF runtime security that blocks, not just logs
Falco and most eBPF security tools can only alert after the fact. Tetragon, Cilium's runtime security engine, can do more — kill a process synchronously in the kernel before the syscall even returns. We break down the TracingPolicy anatomy, enforcement risks, and the safe rollout pattern: audit first, Sigkill later.
Sidecar-free service mesh: Cilium Service Mesh next to Istio Ambient
Cilium Service Mesh handles mTLS and L7 routing on the eBPF datapath with no separate proxy components at all — unlike Istio Ambient, which drops the sidecar but keeps ztunnel and waypoint. We compare the architectures, the honest limitations, and turn on mTLS in a cluster that already runs Hubble.
eBPF without the pain: Cilium and network observability in Kubernetes
What eBPF is in plain terms, why Cilium beats kube-proxy and sidecars, how Hubble shows flows and drop reasons, and what you need to stand it all up in a kind cluster in an evening.
