Sardine alternatives: 10 tools compared (October 2026)

Socure is a US platform for identity verification and fraud prevention. Banks, fintechs, government agencies and online businesses use it to verify new customers, score fraud risk and run compliance checks such as watchlist screening in one decision workflow.

Key functions

• Sigma Identity Fraud V4.5 scores third-party identity fraud with a transformer model
• Separate models for synthetic identities and first-party fraud
• Predictive DocV checks ID documents and selfies with liveness detection

Compared with Sardine

• Publishes a price (from $0.80 per test); Sardine quotes on request.
• Targets companies under 50 employees, which Sardine does not.
• Names 3 security certificates, Sardine 0.
• Different pricing model: usage-based instead of contact for pricing.

Check before buying: Socure stores personal information in the United States, so EU and UK buyers need a transfer basis and a data processing agreement; the privacy policy names an EU representative under Article 27 GDPR. Several products rely on US data sources such as Social Security records, so test coverage for your own markets. Clarify how model scores feed into automated declines and how analysts review those cases.

Shift Technology sells AI agents that support insurers in claims handling, fraud detection, subrogation and payment integrity. It serves property and casualty, travel, health, workers' compensation and life insurers.

Key functions

• AI agents assess coverage and liability from the policy, claim and documents
• Claims fraud detection with case assignment to investigators
• Subrogation opportunity detection with negotiation guidance

Compared with Sardine

• Headquartered in France, Sardine in United States.
• Names 2 security certificates, Sardine 0.
• Strong in the same markets as Sardine: United States.

Check before buying: Claims files often contain health data, which falls under GDPR Article 9, so check the data processing agreement and hosting location. Fraud detection is excluded from the high-risk list in Annex III No. 5 of the EU AI Act, while pricing or risk assessment in life and health insurance is high-risk. Clarify outsourcing documentation under EIOPA guidelines and DORA.

Stripe Radar is the fraud prevention layer of Stripe's payment platform. It scores card and other payments, customer accounts and connected accounts in real time and suits merchants, platforms and marketplaces of any size that already process payments with Stripe.

Key functions

• AI model scores payments, accounts and customers for fraud risk in real time
• Risk scores from 0 to 99 and adaptive 3D Secure from the Plus plan up
• Radar Assistant and agentic insights help write rules and analyze fraud

Compared with Sardine

• Publishes a price (from €0.05 usage-based); Sardine quotes on request.
• Targets companies under 50 employees, which Sardine does not.
• Different pricing model: usage-based instead of contact for pricing.

Check before buying: Radar only protects payments processed by Stripe, so a bank or merchant with several acquirers needs another tool for the rest. Fees per screened transaction add up with volume, including subscription renewals that Radar reviews. Fraud detection is not high-risk under Annex III No. 5 of the EU AI Act, but review rules that decline genuine customers should be monitored.

Zest AI builds machine learning credit models that credit unions, community banks and specialty lenders use to approve or decline consumer loans automatically. The platform adds fair lending analysis, fraud detection and portfolio analytics.

Key functions

• Custom machine learning credit models trained on the lender's own data
• Automated credit decisions for a large share of applications
• Fair lending optimization with searches for less discriminatory alternative models

Compared with Sardine

• Targets companies under 50 employees, which Sardine does not.
• Strong in the same markets as Sardine: United States.

Check before buying: Automated credit decisions on consumers are high-risk under Annex III No. 5 of the EU AI Act and subject to US fair lending and adverse action rules, so every decline needs explainable reasons and human oversight. Zest AI focuses on the US market, so European lenders should check data location, outsourcing documentation under EBA guidelines and DORA, and whether support covers their market.

Credolab scores loan applicants using anonymized device and behavioral metadata collected through a mobile or web SDK. Banks, digital lenders and fintechs use it to assess applicants with little or no credit bureau history.

Key functions

• Fraud signals such as emulators, automated attacks and velocity checks

Compared with Sardine

• Publishes a price (from $4,485 per year); Sardine quotes on request.
• Targets companies under 50 employees, which Sardine does not.
• Different pricing model: flat fee instead of contact for pricing.

Check before buying: Scoring the creditworthiness of individuals is high-risk under Annex III No. 5 of the EU AI Act, so lenders need documented human oversight and explainable reasons for declines. Check the consent flow under GDPR and whether behavioral metadata counts as personal data in your market. Hosting regions are not published, which matters for outsourcing under EBA guidelines and DORA.

ComplyAdvantage offers Mesh, a platform for anti-money laundering and financial crime compliance that combines customer and payment screening, transaction monitoring and AI agents for alert handling.

Key functions

• Agentic AI resolves up to 85 percent of routine alerts on its own, according to the vendor

Compared with Sardine

• Headquartered in United Kingdom, Sardine in United States.
• Targets companies under 50 employees, which Sardine does not.
• Different pricing model: flat fee instead of contact for pricing.

Check before buying: Check whether the Starter plan's entity limits fit your customer base, since transaction monitoring requires Enterprise. Overage beyond the allowance is billed in the next cycle. AML alert decisions carry regulatory liability, so document how agentic closures are reviewed. Ask where customer data is hosted.

Compared with Sardine

• Strongest elsewhere: United Kingdom.

Check before buying: Fraud detection is expressly excluded from the high-risk list in Annex III No. 5 of the EU AI Act, but model decisions still need to be explainable to investigators and customers. A hosted setup counts as outsourcing under EBA guidelines and DORA, so contracts need audit and exit rights. Ask how the Visa integration will change the product roadmap, contract party and support.

Feedzai offers a RiskOps platform that combines fraud prevention, scam detection, identity checks and anti-money laundering for banks, payment service providers and acquirers. Its core is a set of machine learning models that score transactions in real time.

Key functions

Compared with Sardine

• Strongest elsewhere: Portugal.

Check before buying: Fraud detection is excluded from the high-risk list in Annex III No. 5 of the EU AI Act, yet blocked payments and closed accounts still need explainable reasons. Check the hosting model and data location, because a cloud setup is outsourcing under EBA guidelines and DORA. Clarify whether network intelligence shares your transaction data with other institutions and on what legal basis.
