The short version

  • Each has a real cost: 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.; Sardine signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • They diverge on capability: NordVPN covers NordLynx, Sardine covers Device intelligence.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

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.

Sardine

  • Signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • Behavioural and device telemetry collection needs a documented lawful basis under GDPR, and EU privacy reviews frequently delay rollouts that were scoped as engineering work.
  • Pricing is per session or per active user, so a consumer product with many low value sessions pays in proportion to traffic rather than to fraud exposure.
  • As a younger private company it lacks the enforcement-tested audit history that a bank examiner expects, which makes it a harder sell inside a regulated bank than inside a fintech.
  • It is strongest on session-time signals and weaker as a system of record for long horizon AML typologies, so larger institutions end up running it alongside a traditional monitoring platform rather than instead of one.

Answered from the vendors’ own pages

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.

Sardine: Does Sardine do document verification?

It focuses on device, behavioural and transaction signals, and integrates identity verification providers rather than being one. Treat it as complementary to a KYC vendor.

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.

Sardine: What does it need from us to work?

An SDK in your web and mobile applications plus transaction feeds. Without the client side collector you lose the signals that differentiate it.

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.

Sardine: Is pricing published?

No. It is quoted, typically per session or per monthly active user with an annual volume commitment.

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.
