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; NordVPN a server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.
  • They diverge on capability: Cilium covers eBPF datapath, NordVPN covers NordLynx.
  • Prices and features above were last checked on 30 August 2026.

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

NordVPN

  • A buyer choosing on evidence rather than claims, who wants a no-logs policy that has been audited more than once by a named firmnot Cilium
  • Households and individuals wanting one subscription across ten devices including a smart TVnot Cilium
  • Travellers and remote workers on hotel and airport networks who need obfuscation where plain VPN protocols are blockednot Cilium
  • Small teams needing basic remote access to a shared resource, via the NordLayer business product rather than the consumer appnot 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

NordVPN

  • A server in a Finnish datacentre was accessed in March 2018 through a remote management interface left exposed by the hosting provider, and NordVPN did not disclose it until October 2019, so a buyer relying on the company's transparency is relying on a track record that includes a nineteen-month delay.
  • Pricing depends on a long initial term and reverts to the standard rate at renewal, so the monthly figure that justified the purchase is not what the subscriber pays in the third year, and the cheapest way to stay is usually to cancel and re-subscribe.
  • Panamanian registration is selected for the absence of a data retention law, but it also means a subscriber with a dispute has little practical recourse, and the protection rests on a corporate structure the customer cannot inspect or enforce against.
  • NordLynx is unavailable for manual and router configurations, so the one device that could cover an entire home network falls back to OpenVPN or IKEv2 with the associated throughput loss, and obfuscated servers likewise only run over OpenVPN.
  • Features such as Threat Protection are implemented in the client rather than in the network, so any device using a manual configuration, a router or an unsupported platform receives a bare tunnel without the protections the subscription is sold on.

Answered from the vendors’ own pages

Cilium: Is Cilium free?

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

NordVPN: What jurisdiction is NordVPN under?

The VPN service company is registered in Panama, which has no mandatory data retention law for these services. The wider Nord Security group operates from Lithuania.

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.

NordVPN: Has the no-logs claim actually been audited?

Yes, more than once. PwC Switzerland examined it in 2018 and 2020 and Deloitte in later engagements. Each is a point-in-time assurance report over stated policy and server configuration, not ongoing monitoring.

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.

NordVPN: What happened in the 2018 breach?

An attacker reached one rented server in Finland via an insecure remote management tool left in place by the datacentre provider, and obtained a TLS key that had expired. NordVPN disclosed it in October 2019, nineteen months later, and afterwards moved the estate to RAM-only servers.

NordVPN: How many devices does one subscription cover?

Ten simultaneous connections. A router configured with the service counts as one connection regardless of how many devices sit behind it.

NordVPN: Does it work on restrictive networks?

There are obfuscated servers intended for networks that block VPN protocols, but they run over OpenVPN only and no provider can guarantee access in a country that actively filters. Treat it as best effort.
