Sardine Alternatives for Fraud and Compliance (2026)

The best Sardine alternatives in 2026 are Runtime, Unit21, Alloy, SEON, Feedzai, and Sift. Unit21 is the closest match for AML and fraud operations, Alloy for identity orchestration, SEON for mid-market teams that want published pricing, Feedzai for banks, and Sift for commerce fraud. Runtime is the AI agent harness for payment and fintech teams, and it works the cases any of them raise across support, payment ops, finance, and risk.

We make Runtime, so weigh our pick accordingly. Vendor facts below come from each vendor's own site or announcements.

Why teams look for Sardine alternatives

Sardine is one of the broadest platforms in financial crime. It covers onboarding, fraud, and AML, lists ten AI agents from OSINT Search to SAR Generation, runs the Sonar consortium, and was named a Leader in the Forrester Wave for financial crime management in Q3 2026. The reasons teams still compare are about fit:

• Fit. Some teams only need AML case work and filing, or only commerce fraud, and do not want a full platform.
• Scope. Sardine's agents work inside Sardine. Cases that need the ledger, processor, or support history leave its scope.
• Deployment. Sardine is hosted. Banks with on-premise requirements, or fintechs that want agents in their own cloud, look elsewhere.
• Pricing model. Sardine does not publish pricing.

The best Sardine alternatives

Runtime

Runtime is the AI agent harness for payment and fintech teams. It does not score fraud. It gives risk, compliance, payment ops, finance, and support agents that run on isolated computers in your cloud and work the cases a risk platform raises, using the ledger, processor, bank files, help desk, and your risk vendor's case data. Agents draft the decision with evidence and wait for a person before money moves.

Best for: fintechs whose fraud and AML cases spill into other teams. Strengths: your cloud and your models; approvals and a full record per run; agents built from your SOPs with a forward-deployed engineer. Watch out for: you still need a detection platform. Runtime sits next to one.

Unit21

Unit21 calls itself AI risk infrastructure for fraud and AML. It covers real-time and AML transaction monitoring, sanctions and payment screening, case management, customer risk rating, a fraud consortium, and device intelligence. It files SARs and CTRs directly with FinCEN and STRs with FINTRAC. Its Detection and Investigation agents launched in 2025, and an Agentic Task Builder followed in July 2026.

Best for: fintechs, sponsor banks, and credit unions running AML programs. Strengths: detection through filing on one platform; named customers such as Chime, Brex, and Green Dot Bank; connectors to bank cores and data warehouses. Watch out for: no native KYC product, and its agents do not close cases or file on their own.

Alloy

Alloy is an identity and risk decisioning platform for banks, credit unions, and fintechs. It orchestrates hundreds of data partners into no-code workflows for onboarding, KYC, KYB, AML screening, transaction monitoring, fraud, and credit decisioning. Its AI Assistant, launched in February 2026, recommends decisions for a person to approve, and Alloy reports more than 900 financial institutions and fintechs as customers.

Best for: banks and lenders that want control over many data providers. Strengths: data partner choice; lifecycle decisioning past onboarding; credit decisioning on the same engine. Watch out for: it orchestrates other vendors' signals rather than running its own device consortium. Pricing is not published.

SEON

SEON combines fraud prevention and AML compliance using more than 1,100 first-party data signals. It covers digital footprint, device intelligence, and behavioral biometrics, ID verification and liveness, AML screening, transaction monitoring, case management, and SAR and STR reporting, with an AML screening agent for validating hits. Customers named on its site include Plaid, Revolut, and Afterpay.

Best for: mid-market fintech, lending, iGaming, and marketplaces. Strengths: published pricing, starting at $699 per month for 2,500 fraud checks; an average 14-day implementation; fraud and AML in one product. Watch out for: AML and case management are on the custom Premium plan, not Starter.

Feedzai

Feedzai is a fraud and financial crime platform it calls RiskOps, built for banks, payment processors, and acquirers. It covers transaction, new-account, and scam fraud, identity verification, AML transaction monitoring, and watchlist screening. In September 2026 it launched Farol, an agentic investigator with SAR drafting. Customers named on its site include Mastercard, Fiserv, and CaixaBank.

Best for: banks and processors with large transaction volumes. Strengths: bank-grade scale; cloud or on-premise deployment; agents inside the investigation flow. Watch out for: built for financial institutions, so lighter-weight fintechs may find it heavy. Pricing is not published.

Sift

Sift is a fraud decisioning platform with Payment Protection, Account Defense, and the Sift Score API. It says it processes more than 1 trillion events a year, and its Attack Detection Agent groups fraud attacks into investigations. Customers include Patreon, Yelp, and Turo.

Best for: digital businesses whose main problem is payment fraud and account abuse. Strengths: a very large event network; mature decisioning and workflows; strong in commerce and marketplaces. Watch out for: no listed KYC or AML products, so a regulated fintech pairs it with other vendors.

Where Runtime enters the picture

Every platform here decides whether something is risky, and most now ship agents that help analysts inside their own case queue. The case rarely stays there. An AML alert on a merchant becomes a payout hold for payment ops, a ticket for support, a reserve decision for finance, and an RFI from the partner bank. Today each team investigates the same merchant in its own tool, and the record your sponsor bank asks for is spread across all of them.

Runtime is the AI agent harness for payment and fintech teams. It keeps Sardine or whichever platform you choose as the detection layer and puts agents on the work around it. The agent reads the alert through the vendor's API, checks processor history, the ledger, and prior tickets, drafts the decision and the RFI response, and waits for approval before a payout is released or a reserve applied.

• No single vendor to depend on. Agents run in your AWS, GCP, or Azure account or fully self-hosted, on your choice of sandbox provider with fallbacks, using Claude, GPT, Gemini, or open-weight models, with harness routing across Claude Code, Codex, and OpenCode.
• Guardrails you set. Read-only by default, approvals before money moves, RBAC, masked credentials, PII and PCI data stripped from prompts and logs, and every run recorded for your examiner.
• Built for teams. Risk, compliance, payment ops, finance, and support share agents, templates, and one memory of every case.
• An engineer, not an account executive. A forward-deployed AI engineer with a payments background from Hulu's payments team at Disney, Finix, Modern Treasury, or BlackRock builds the first agents with your team.
