Is Cilium or Wiz better?

Neither clearly leads. Cilium starts at Free and Wiz at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Cilium or Wiz?

Cilium has a free tier; the other does not. Paid plans start at Free for Cilium and On request for Wiz.

Does Cilium or Wiz run on more platforms?

Cilium runs on Kubernetes, Linux. Wiz runs on web, api.

Can I use Cilium for free?

Yes. Cilium has a free tier, so you can try it without paying. Wiz starts at On request.

What is Cilium best used for?

Cilium is most often used for kubernetes networking at a scale where iptables-based cni performance degrades, network policy expressed on workload identity rather than fragile ip rules, seeing which services actually talk to each other, and what policy is dropping. Of those, kubernetes networking at a scale where iptables-based cni performance degrades and network policy expressed on workload identity rather than fragile ip rules are not what Wiz is typically brought in for.

What can Cilium do that Wiz cannot?

Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Wiz covers Cloud security posture management, Code security (Wiz Code), Runtime threat detection (Wiz Defend), AI security agents.

The short version

Only Cilium has a free tier, so it costs nothing to try first.
Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Wiz no public pricing; licensing requires a custom quote based on workloads and sensors.
They diverge on capability: Cilium covers eBPF datapath, Wiz covers Cloud security posture management.
Prices and features above were last checked on 29 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cilium

Requires a recent Linux kernel, which rules out older distributions and some managed environments
eBPF is genuinely hard to debug when it misbehaves, and the skill is rare on most teams
Broad scope — CNI, policy, mesh, observability — means the learning curve covers several domains at once

Wiz

No public pricing; licensing requires a custom quote based on workloads and sensors.
Modular licensing across Cloud, Code, Defend, and Sensor products can complicate cost planning.
Full runtime protection value depends on deploying Wiz Sensor agents, adding operational overhead.
Primarily aimed at mid-to-large enterprises despite the smaller Wiz Go bundle.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

Yes, open source and CNCF-graduated. Isovalent sells an enterprise distribution and support.

Wiz: How much does Wiz cost?

Wiz does not publish standard pricing. The platform uses modular licensing based on workloads, active developers, log ingestion, or sensors. All pricing requires requesting a custom quote directly from the company.

Source

Cilium: What does eBPF change?

It lets Cilium run packet-processing programs inside the kernel instead of relying on iptables rule chains, which behave poorly as the number of services grows.

Wiz: Does Wiz offer a free trial?

No free trial information is mentioned on Wiz's pricing page. Pricing is determined by custom quote based on organizational needs.

Source

Cilium: Does Cilium replace a service mesh?

It can cover much of what a mesh does without sidecars, though full mesh feature sets still favour Istio or Linkerd.

Wiz: What products does Wiz offer?

Wiz provides five modular licensing options: Wiz Cloud, Wiz Code, Wiz Defend, Wiz Sensor, and Wiz Go Bundle for SMBs, allowing organizations to scale based on specific security requirements.
