The short version

  • Only Brave Browser has a free tier, so it costs nothing to try first.
  • Each has a real cost: Brave Browser brave Firewall + VPN features require paid subscription; 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: Brave Browser covers Built-in ad blocker, 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.

Brave Browser

  • Brave Firewall + VPN features require paid subscription
  • Brave Talk Premium is subscription-based, not included in free tier
  • Brave Rewards programme is optional and requires user participation

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

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.

Brave Browser: Does Brave offer any paid features?

Yes. Brave offers subscription-based features including Brave Firewall + VPN (protecting every app on your entire device across up to 5 devices) and Brave Talk Premium, though specific pricing is not listed on the main page.

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.

Brave Browser: Can I earn money using Brave?

Yes. Brave Rewards is an optional program that allows users to earn BAT tokens by viewing privacy-protecting ads. Tokens earned can be stored securely in Brave Wallet.

Source
Sardine: Is pricing published?
