TL;DR
eBPF is no longer academic — by 2026 it is the default substrate for Linux
observability and security. But the market has split in two: Kuberscale
platforms (Falco, Tetragon, Tracee, Cilium Hubble) that assume you run
Kubernetes, and standalone agents (Talus) that assume you just have Linux
servers and want results before lunch.
This article compares the five most used tools on standalone process
monitoring and fleet behavior — the exact criteria that matter when you
are not running a CNI and don't want a sidecar on every node.
What "ebpf monitoring tools" means today
In 2026 the category is overloaded, so let's scope it precisely. I am comparing
tools that:
- Attach eBPF programs to kernel events (not polling
/proc). - Aggregate events per process over a window.
- Can emit alerts and ideally act (kill the process).
- Scale beyond one host with a fleet view.
I am not comparing full EDR/XDR suites, distros, or SaaS SIEMs that happen
to ingest eBPF agents. Those are a different purchase committee.
The landscape
| Tool | Runtime model | K8s-coupled? | Kill? | Fleet? | Price |
|---|---|---|---|---|---|
| Talus | 1 static binary, no cluster | ❌ | ✅ SIGKILL <1s | ✅ | $50/node/yr |
| Falco | Daemonset / standalone agent | ⚠️ prefers k8s | ❌ alerts only | ⚠️ via SIEM | Free |
| Tetragon | Cilium + Hubble agent | ✅ (Cilium) | ✅ via policy | ✅ via Hubble | Free |
| bpftrace | CLI one-off traces | ❌ | ❌ | ❌ | Free |
| Tracee | Single-agent + k8s helm | ⚠️ helm-heavy | ❌ | ⚠️ via integrations | Free |
Numbers from each project’s public docs + GitHub as of 2026-09.
Falco — the CNCF default, not your laptop
Falco is brilliant if your entire world is Kubernetes. Inside a cluster its
rules engine (YARA-ish condition: language) is mature and well-supported.
But spin it up on five standalone servers and you immediately hit friction:
- It expects either a Kubernetes daemonset or a host-level install that still configures itself like a k8s workload.
- Rules ship as a big YAML ruleset you must trim; the signal-to-noise ratio on a non-K8s host is poor for weeks.
- It detects only. Response is "alert someone else" — no kill.
Talus treats those five servers like what they are: Linux. One binary, one
--auto-kill flag, verdict to SIGKILL in the same one-second window that
detects.
Tetragon — Cilium's gift to Kubernetes
Tetragon belongs to Cilium. It is the most capable eBPF security product on the
market inside Kubernetes, and its process lineage graph is gorgeous. But the
same sentence is "inside Kubernetes": it depends on the Cilium CNI, Hubble
relay, and a Kubernetes operator. If you are reading this and you do not deploy
Cilium, Tetragon is a large amount of correct software you don't need.
Talus deliberately couples to nothing: no CNI, no CRI, no kubelet. Kernel 5.8+
and root is enough.
bpftrace — debugging, not guarding
bpftrace is the strace of eBPF and that is its superpower. It is unbeatable for
one-off forensic looks:
bpftool prog | bpftrace -e 'tracepoint:syscalls:sys_enter_openat { printf("%s %s\n", comm, str(args->filename)); }'
But a monitoring product is a different shape. bpftrace is a CLI; it has no
daemon, no state across boots, no fleet, no alerting channel you can point at a
Slack webhook from a config file, and no concept of "kill the process that did
this."
Tracee — single agent, but still a project
Tracee (Aqua) can run as a single agent and has good forensic export. Its
default install path, though, is Helm, and tuning it without k8s is a doc-dive.
For an operator on three bare-metal hosts, Tracee is a reasonable second choice
only if you are already drinking the Aqua ecosystem.
Where Talus wins
- Standalone hosts. eBPF tracepoints in a single static binary; no kernel modules, no reboot, no cluster.
-
Detect + respond in the same second. Per-process open-rate heuristic in a
1-second window,
SIGKILLimmediately, guardrails + whitelists so it cannot kill your own backup job. - Privacy. Runs on your hosts. No cloud, no telemetry, no third-party.
- Fleet, not a sidecar. One dashboard for the whole fleet, keyed to a per-machine license.
- MIT core. The detection engine stays MIT and public; the paid tier is the license keys and response guards.
The honest trade-off
You give up Kubernetes-native integration. Talus is not going to sit in your
Cilium CNI graph or emit to Hubble. If you are 100% Kubernetes with Cilium
today, Tetragon is better fit. If you run any server that is not in that
cluster — edge, bare metal, a CI box, a customer's host — Talus is what closes
the gap.
Quick decision
- All workloads in k8s + Cilium → Tetragon.
- Mostly k8s, but some stray hosts → both: Tetragon in-cluster, Talus on the stray boxes, one dashboard.
- Real Linux servers, edge, air gap, or just "I want this on before lunch" → Talus.
