Application-level logging can be disabled by a compromised process, so security visibility must not rely on attacker cooperation.
eBPF kernel-level syscall probing remains effective even with root in containers, and disabling it is significantly harder than killing a user-space agent.
Consolidating user-space security agents with an eBPF agent can reduce security CPU use by 60–80% and lower telemetry volume via kernel-side filtering.
Phased eBPF rollout—observe, then alert, then enforce—prevents disruptive enforcement that can break critical services.
