Understanding the Threat Landscape

From account takeover to triangulation fraud, criminals remix the same tactics: stolen credentials, synthetic identities, and socially engineered urgency. Recognizing patterns early helps you tune defenses, educate users, and route suspicious activity before money moves.

Building Trust with Verification

Combine email and device signals with government ID verification and liveness checks for higher-value actions. Progressive friction ensures low-risk users breeze through while risky profiles face deeper scrutiny at precisely the right moments.

Building Trust with Verification

Transparent ratings, dispute history, delivery reliability, and verified business details create a reputation graph stronger than any single score. Encourage users to complete profiles and celebrate trustworthy behavior to elevate marketplace-wide safety norms.

Payment Security Foundations

Encrypt sensitive data in transit and at rest, then replace raw numbers with network tokens. This shrinks your exposure surface, eases compliance, and blunts the value of stolen details if attackers breach adjacent systems.

Payment Security Foundations

Use adaptive authentication like 3‑D Secure 2 with risk-based exemptions. Reduce friction through trusted beneficiaries and device recognition, so legitimate customers sail through while high-risk attempts face step-up verification.

Protecting Users with Thoughtful Design

Warnings work when they feel timely and relevant. Highlight unusual payment routes, mismatched shipping addresses, or urgent off-platform requests. Encourage users to pause, verify, and report—then reward helpful reports with visible community appreciation.

Data and Machine Learning Defenses

Combine velocity checks, device fingerprinting, proxy detection, and historical behavior into a single score. Route low-risk transactions instantly, challenge medium risk, and block high-risk to protect both conversion and safety.

Data and Machine Learning Defenses

Typing cadence, mouse travel, and mobile motion patterns differentiate humans from bots and owners from impostors. These subtle cues add silent protection without adding friction, especially powerful during login and payment confirmation flows.

Incident Response and Transparency

Write clear playbooks for account compromise, data exposure, and payment abuse. Rehearse cross-functional drills so engineers, legal, and support move as one team when minutes truly matter.

Global Compliance and Ethical Guardrails

Map PSD2, PCI DSS, and local KYC/AML rules to user journeys. Use exemptions thoughtfully, log decisions, and test flows frequently. Great compliance feels invisible because it is seamlessly woven into the product.
