TL;DR: Marketplace platforms are adding identity verification, behavioral analytics, transaction monitoring, and real-time risk scoring to reduce fraud while improving onboarding and dispute handling, according to Sumsub. The shift shows that trust and safety for marketplaces now depends on identity governance, not just fraud tooling.
Editorial analysis by NHI Mgmt Group, based on content published by SumSub: “Sumsub Introduces AI-powered Platform for Marketplaces”.
Key questions
Q: How should marketplaces set trust controls for buyers, sellers and merchants?
A: Marketplaces should not use a single onboarding policy for every participant.
Q: Why do static onboarding checks fail in marketplace fraud prevention?
A: Static checks only answer whether an account looked legitimate once.
Q: What breaks when marketplaces do not link identity to transaction monitoring?
A: Without that linkage, the platform cannot connect a verified identity to suspicious payment patterns, scam behaviour or dispute abuse.
Practitioner guidance
- Define role-specific trust tiers Separate buyers, sellers, merchants and independent professionals into distinct onboarding paths with different evidence requirements and risk thresholds.
- Link verification to live monitoring Feed identity, device and behavioural signals into transaction monitoring so suspicious activity is evaluated as it happens, not only at account creation.
- Treat promotion abuse as identity abuse Correlate referral activity, multi-accounting and bonus claims with shared devices, repeated identities and unusual transaction patterns.
Bottom line: Marketplace fraud prevention now depends on identity governance that covers onboarding, behaviour and transaction context together.

Marketplace identity governance is becoming a lifecycle discipline, not a point-in-time verification problem. The article's core message is that onboarding, transaction monitoring, and fraud controls are converging into one trust layer. That is consistent with OWASP-NHI and ZT-NIST-207 thinking: identity state must be continuously evaluated, not assumed stable after registration. Practitioners should treat marketplace participants as governed identities whose risk changes during the relationship.
A few things that frame the scale:
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to The State of Secrets in AppSec.
- Only 44% of developers are reported to follow security best practices for secrets management, according to The State of Secrets in AppSec.
A question worth separating out:
Q: How can organisations reduce manual review without losing control?
A: By using dynamic risk scoring to route only ambiguous or high-risk cases into manual review. Routine low-risk activity can stay automated, but the policy must define clear thresholds, escalation paths, and evidence retention so automation improves speed without removing accountability from fraud and compliance teams.

Marketplace trust is now an identity governance problem, not a fraud-only problem. The article shows that onboarding, verification, behavioural monitoring and dispute handling are converging into one control plane. That matters because marketplaces do not fail only when fraud is missed, but when trust decisions are inconsistent across buyer, seller, merchant and partner lifecycles. Practitioners should treat marketplace trust as governed identity policy, not as a standalone detection workflow.
A few things that frame the scale:
- Nearly 60% of companies reported that fraud losses were still increasing in 2025.
A question worth separating out:
Q: What does the shift to marketplace trust controls mean for IAM and fraud teams?
A: It means account governance, dispute handling and fraud detection need shared ownership. When identity, device and behavioural signals sit in separate workflows, the organisation sees fragments instead of trust decisions. Teams should align on one operating model for onboarding, ongoing risk review and exception management.
