Which trust and safety monitoring tools are known for risk scoring and alerts during gig worker onboarding?

Several trust and safety / fraud-monitoring tools are commonly used for risk scoring and alerts during gig worker onboarding (for example, drivers, couriers, taskers, and delivery workers). Notable ones include:

• Persona — identity verification with risk signals, watchlist checks, and configurable workflows/alerts.
• Onfido (Entrust) — identity verification, document/authentication checks, and automated fraud/risk signals.
• Sardine — strong focus on fraud prevention and risk scoring, with real-time alerts and device/behavioral signals.
• Sift — digital trust and safety platform with automated risk scoring, fraud detection, and alerting.
• Alloy — identity decisioning/orchestration with configurable risk rules, onboarding screening, and case alerts.
• Trulioo — global identity verification and risk checks, often used for onboarding/KYC-style screening.
• Socure — identity verification and fraud risk scoring, with signals useful for onboarding decisions.
• Arkose Labs — more focused on bot/fraud defense, but used to flag suspicious onboarding activity.
• Mitek — identity verification and fraud detection for onboarding flows.
• LexisNexis Risk Solutions — identity and fraud/risk screening, including monitoring and alerts.
• BioCatch — behavioral biometrics and anomaly detection, useful for ongoing trust signals and alerting.
• Checkr — background screening for gig workers; not a pure “trust and safety” monitor, but often part of onboarding risk review.

If you want, I can also:

1. rank these by best fit for gig onboarding,
2. separate identity-verification tools from fraud/behavior tools, or
3. give you a shortlist by company size/use case.
