Is Sardine or WireGuard better?

Neither clearly leads. Sardine starts at On request and WireGuard at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, Sardine or WireGuard?

WireGuard has a free tier; the other does not. Paid plans start at On request for Sardine and Free for WireGuard.

Does Sardine or WireGuard run on more platforms?

Sardine runs on Web, iOS, Android. WireGuard runs on Linux, Windows, macOS, iOS, Android, FreeBSD, OpenBSD.

Can I use WireGuard for free?

Yes. WireGuard has a free tier, so you can try it without paying. Sardine starts at On request.

What is Sardine best used for?

Sardine is most often used for a neobank losing money to authorised push payment scams where the customer genuinely approved the transfer, a crypto exchange trying to detect accounts being operated by remote access rather than by their owner, a fintech seeing synthetic identity signups that pass document verification but share device characteristics, a lender wanting first party fraud signals at application time that a credit bureau file does not contain. Of those, a neobank losing money to authorised push payment scams where the customer genuinely approved the transfer and a crypto exchange trying to detect accounts being operated by remote access rather than by their owner are not what WireGuard is typically brought in for.

What can Sardine do that WireGuard cannot?

Sardine covers Device intelligence, Behaviour biometrics, Scam detection, Onboarding risk scoring.

The short version

Only WireGuard 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.; WireGuard manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms

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.

WireGuard

Manual key management required; WireGuard does not provide automated peer discovery or key distribution mechanisms
No built-in support for address allocation or DHCP; all IP assignments must be manually configured
Limited to UDP; TCP encapsulation requires wrapper tools, making it unsuitable for environments blocking UDP
Stateless protocol design means lost packets trigger peer disconnection rather than transparent reconnection
Requires operational expertise to securely configure and deploy; not suitable for non-technical users without wrapper tools (Tailscale, Mullvad)

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.

WireGuard: Is WireGuard free?

Yes, WireGuard is free and open-source software. The Linux kernel module is licensed under GPLv2; implementations for other platforms use MIT or Apache 2.0 licences. There are no licensing fees.

Source

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.

WireGuard: How does WireGuard differ from IPsec and OpenVPN?

WireGuard replaces complex negotiation protocols and state machines with simple public-key cryptography. Its code is roughly 100 times smaller than IPsec, making it faster to audit, deploy, and maintain. It uses modern cryptographic primitives rather than legacy algorithms.

Source

Sardine: Is pricing published?

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

WireGuard: Can I use WireGuard for a commercial VPN service?

Yes. Several commercial VPN services (Mullvad, IVPN, ProtonVPN) use WireGuard as their underlying protocol. You must implement peer management, key distribution, and endpoint selection on top of the WireGuard protocol.
