The short version

  • Only Windscribe has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Windscribe free tier's 10GB cap still requires email confirmation and social sharing to unlock, unlike some no-strings-attached competitors.
  • They diverge on capability: Sardine covers Device intelligence, Windscribe covers Firewall / default block.
  • 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.

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.

Windscribe

  • Free tier's 10GB cap still requires email confirmation and social sharing to unlock, unlike some no-strings-attached competitors.
  • Build-A-Plan's low cost only covers selected locations, so broad global coverage still requires the full Pro plan.
  • Server speeds and streaming reliability are inconsistent compared to larger premium VPN providers.
  • Customer support is primarily ticket/community-based rather than live chat for lower tiers.

Answered from the vendors’ own pages

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.

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.

Sardine: Is pricing published?

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