The short version

  • Only Nebula has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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; Nebula the open source project has no user interface, no enrolment workflow and no revocation service, so certificate issuing, distribution and expiry become scripts you write and then have to keep working.
  • They diverge on capability: Juniper Mist covers AI-driven assurance, Nebula covers Certificate carried identity.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

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

Juniper Mist

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

Nebula

  • Flattening a network across several clouds and datacentres without VPC peering or route tablesnot Juniper Mist
  • Very large fleets where a central policy service on the connection path is unacceptablenot Juniper Mist
  • Environments that already run an internal certificate authority and want the network to use itnot Juniper Mist
  • Replacing per host iptables rules with policy written against roles that follow the hostnot Juniper Mist

Where each one falls short

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

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

Nebula

  • The open source project has no user interface, no enrolment workflow and no revocation service, so certificate issuing, distribution and expiry become scripts you write and then have to keep working.
  • Revoking a compromised host means distributing a blocklist entry to every other host and reloading them, which is a fleet wide operation rather than a click, and easy to get wrong under pressure.
  • Changing a host group membership means reissuing and redeploying its certificate, so policy changes are a deployment rather than a configuration edit.
  • There is no identity provider integration or single sign on in the open source version, so it maps well to servers and badly to a fleet of user laptops.
  • NAT traversal is best effort and hosts behind symmetric NAT need a relay configured deliberately, so connectivity failures show up as intermittent rather than immediate and are awkward to diagnose.

Answered from the vendors’ own pages

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.

Nebula: Does it use WireGuard?

No. Nebula predates the common WireGuard mesh tools and uses the Noise protocol framework with its own certificate format.

Juniper Mist: Is pricing published?

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

Nebula: Can I run it without Defined Networking?

Yes, entirely. Defined Networking sells the control plane conveniences, not the network itself.

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.

Nebula: How do I revoke a host?

Add its certificate fingerprint to the blocklist in the configuration of the other hosts and reload them. There is no online revocation check.

Nebula: Is it a good fit for laptops?

Less so than the identity provider based tools. There is no single sign on, so every laptop needs a certificate issued and renewed by whatever process you build.
