Born from the Linux kernel, eBPF allows sandboxed programs to run inside the kernel without modifying kernel source code or loading modules. This means you can intercept network packets, trace system calls, monitor application performance, and enforce security policies — all with near-zero overhead and no instrumentation changes to your applications.</p>
