Sidecarless

Tech Radar Digest October 2026: Cilium 1.17, Tetragon 1.4 & eBPF Autonomous Agent Security Answer-First: The October 2026 Tech Radar establishes in-kernel eBPF as the mandatory architectural foundation for autonomous AI agent infrastructure. By pairing Cilium 1.17 sidecarless socket splicing (eliminating 15ms–35ms Envoy IPC tax with sub-1.2ms P99 latency) with Tetragon 1.4 synchronous in-kernel enforcement (SIGKILL in under 12 microseconds), platform engineering teams achieve hardware-grade zero-trust sandboxing and unassailable egress containment. ...

Tech Radar: Cilium 1.17 & Tetragon 1.4: In-Kernel eBPF Observability, Sidecarless Service Mesh & Zero-Trust Sandboxing for Autonomous AI Agents Answer-First: Deploying autonomous AI agent swarms with dynamic tool execution creates severe remote code execution exposure. Cilium 1.17 replaces high-overhead Envoy sidecars with in-kernel sockops socket splicing, reducing P99 latency by 92.3% to 1.12ms under 100K RPS. Concurrently, Tetragon 1.4 intercepts sys_enter_execve within the Linux 6.8 kernel, delivering synchronous SIGKILL termination in under 12 microseconds. ...
