The short version

  • Each has a real cost: Cilium requires a recent Linux kernel, which rules out older distributions and some managed environments; Grype depends on public vulnerability databases, so coverage and false positives vary by ecosystem
  • They diverge on capability: Cilium covers eBPF datapath, Grype covers Image and filesystem scanning.
  • Prices and features above were last checked on 29 August 2026.

What each one covers

Drawn from each product's published feature list. An absence here means we hold no record of it - not that the product lacks it.

Only in Cilium

  • eBPF datapath
  • Identity-based policy
  • Hubble observability
  • Sidecar-free mesh

Only in Grype

  • Image and filesystem scanning
  • SBOM-driven
  • Wide ecosystem coverage
  • Pipeline friendly

What people use each for

The jobs each tool is most often brought in to do.

Cilium

  • Kubernetes networking at a scale where iptables-based CNI performance degradesnot Grype
  • Network policy expressed on workload identity rather than fragile IP rulesnot Grype
  • Seeing which services actually talk to each other, and what policy is droppingnot Grype

Grype

  • Re-scanning stored SBOMs as new CVEs are published, without rebuilding imagesnot Cilium
  • Failing CI when a build introduces a known vulnerabilitynot Cilium
  • Auditing what is actually installed inside a third-party imagenot Cilium

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

Grype

  • Depends on public vulnerability databases, so coverage and false positives vary by ecosystem
  • No triage, exception tracking or reporting UI — that is Anchore’s commercial product
  • Overlaps heavily with Trivy, and most teams pick one rather than running both

Questions people ask

Is Cilium or Grype better?
Neither clearly leads. Cilium starts at Free and Grype at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Cilium or Grype?
Cilium starts at Free and Grype at Free.
Does Cilium or Grype run on more platforms?
Cilium runs on Kubernetes, Linux. Grype runs on Linux, macOS, Windows, Docker.
Can I use Cilium for free?
Both have a free tier, so you can try either at no cost before committing.
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 Grype is typically brought in for.
What can Cilium do that Grype cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Grype covers Image and filesystem scanning, SBOM-driven, Wide ecosystem coverage, Pipeline friendly.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

Grype: Is Grype free?

Yes, open source from Anchore. Anchore Enterprise is the paid platform around it.

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.

Grype: What is the difference between Grype and Syft?

Syft generates the software bill of materials; Grype matches that inventory against vulnerability data. They are designed to be used together.

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.

Grype: Grype or Trivy?

They cover similar ground. Trivy is broader out of the box, including misconfiguration and secret scanning; Grype pairs more cleanly with an SBOM-first workflow.
