VPN and Proxy Fraud Blocker for Shopify
The Opportunity
A merchant-facing app that detects VPN, proxy, and anonymizer traffic at the storefront and checkout, then blocks or challenges suspicious visitors before they can place an order. It helps merchants reduce fraud attempts that reuse different cards and identities.
"The merchant is dealing with repeat fraud attempts and wants a reliable way to stop customers using VPNs or web proxies from completing purchases."
Market Validation
Detailed Analysis
Proposed Solution
Provide IP intelligence and device-risk checks to detect VPN/proxy use, then let merchants choose actions such as block access, hide checkout, require verification, or flag orders for review.
Target Audience
Shopify merchants experiencing fraud, chargebacks, or abuse from masked traffic
Competitive Landscape
NoFraud, Signifyd, Fraud Filter apps, and some geo/IP risk apps with VPN detection features
Implementation Notes
Use IP intelligence APIs and a maintained VPN/proxy reputation database, combine with Shopify storefront/app proxy or theme app extension logic to warn or block suspicious sessions, and provide configurable rules for cart, checkout redirection, and order tagging; note that hard blocking at checkout may be limited by Shopify checkout constraints depending on plan and extension surface.
Evidence from Merchants
Real quotes from Shopify community forums
"I would like to strongly suggest that Shopify implement a built-in ON / OFF toggle that would allow a store owner from immediately preventing anyone using a VPN from being able to complete a purchase on their store."
"I’ve been running a month-long battle with a fraudster (I’m pretty certain it’s the same individual) who seems to have access to a variety of different credit cards and matching customer info."
"it’s incredibly frustrating that Shopify doesn’t have a built-in option to prevent VPN use since VPN usage is a pretty bright sign that someone is likely up to some shady stuff."
