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; Juniper Mist wi-Fi Assurance is a required subscription, not optional support, so the AI-driven monitoring that is the product's core selling point cannot be declined while still running the hardware in a supported way
  • They diverge on capability: Cilium covers eBPF datapath, Juniper Mist covers AI-driven assurance.
  • Prices and features above were last checked on 1 September 2026.

  • Hubble observability
  • Sidecar-free mesh

Only in Juniper Mist

  • Location services

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 Juniper Mist
  • Network policy expressed on workload identity rather than fragile IP rulesnot Juniper Mist
  • Seeing which services actually talk to each other, and what policy is droppingnot Juniper Mist

Juniper Mist

  • A large campus or retail network operations team wanting AI-assisted root-cause analysis rather than manual log correlation for wireless issuesnot Cilium
  • An organisation already standardised on Juniper wired infrastructure wanting a unified wireless and SD-WAN management platformnot Cilium
  • A network team that wants subscriptions decoupled from specific device serial numbers, easing hardware refresh cyclesnot Cilium
  • An enterprise wanting natural-language network troubleshooting through the Marvis virtual assistant rather than raw dashboardsnot 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

Juniper Mist

  • Wi-Fi Assurance is a required subscription, not optional support, so the AI-driven monitoring that is the product's core selling point cannot be declined while still running the hardware in a supported way
  • Pricing is entirely quote-based with no published list price, and third-party estimates of typical contract size vary widely, making it hard to budget before engaging Juniper sales
  • Premium Analytics is priced as a further add-on beyond the already-required base subscription, so the full-featured cost is higher than the headline Wi-Fi Assurance price alone
  • As with other cloud-managed hardware in this category, ongoing cloud connectivity is required for full functionality, and local resilience during an internet outage should be verified before purchase
  • Deployment-level licence attachment eases hardware swaps but still means the licence, not the hardware, is the thing actually being renewed and paid for indefinitely
  • Juniper's acquisition of Mist folds product direction into Juniper's broader roadmap and pricing strategy, which has already shifted since acquisition and may shift again

Can I use Cilium for free?
Yes. Cilium has a free tier, so you can try it without paying. Juniper Mist 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 Juniper Mist is typically brought in for.
What can Cilium do that Juniper Mist cannot?
Cilium covers eBPF datapath, Identity-based policy, Hubble observability, Sidecar-free mesh. Juniper Mist covers AI-driven assurance, Marvis virtual network assistant, Device-agnostic subscriptions, SD-WAN integration.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

Juniper Mist: Is the Wi-Fi Assurance subscription optional?

No, Juniper lists it as a required subscription for Mist wireless deployments; Premium Analytics is a further optional add-on.

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.

Juniper Mist: Is pricing published?

No, Juniper does not publish per-device or per-site pricing; it is quoted per deal.

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.

Juniper Mist: Are licences tied to specific hardware serial numbers?

No, Mist subscriptions attach to the deployment and are not bound to individual device serial numbers, which eases hardware refresh.
