Filtrex · Shopify

Stop fraud before it sells.

Bots swallow stock in seconds. VPN shoppers test stolen cards. Fraudulent orders get shipped, then charged back weeks later. Filtrex screens every visitor on arrival and stops bad traffic before it reaches checkout.

5-signal weighted risk scoring

Read the room before checkout.

Filtrex scores every visitor in real time with five weighted fraud signals, then returns a clear verdict — allow, block, or flag — before the page even settles.

How it blocks

Three layers. One verdict.

Most fraud protection reacts after the damage. Filtrex stops bad traffic at every step of the buying journey, before the order exists.

01

Storefront blocking

Every visitor is screened in real time through the Shopify App Proxy. VPNs, proxies, TOR, bots, and suspicious IPs are stopped on arrival — before they ever see a product.

02

Checkout validation

A Shopify Function (WASM) re-checks every order at checkout, blocking by email, phone, and name on top of the scorecard. Clean shoppers flow through with zero friction.

03

Geographic blocking

Block whole countries or regions (ISO 3166-2) with smart cascades — when a visitor switches countries, Filtrex re-screens and recalculates the verdict instantly.

Features

Everything to keep fraud off the ledger.

Built around the real patterns of fraud, not noisy rule piles. Fast, transparent, and tuned for Shopify.

5-signal risk scoring

Five weighted signals — country risk, anonymity network, bot detection, historical fraud, timezone mismatch — combine into one transparent verdict, Low to Critical. No black box: every score is explainable and tunable.

Block page designer

Five templates — glassmorphism, minimal, alert, dramatic, split — with per-block-reason message overrides, so even blocked visitors stay on brand.

Analytics & heatmaps

Visitor logs, fraud orders, risk distribution, and geographic heatmaps give you a live picture of where the bad traffic comes from — and where it goes.

Live shopper screening

Storefront screening runs on every page load via the App Proxy — real-time allow, block, and flag verdicts with no checkout friction for clean visitors.

Shopify Function (WASM)

Checkout is re-checked by email, phone, and name inside a compiled Shopify Function. Fast, sandboxed, and available on every Shopify plan.

Works on all Shopify plans

No enterprise upgrades required. App Proxy screening plus a Shopify Function means Filtrex protects stores on any Shopify subscription.

FAQ

What merchants ask us first.

Will Filtrex block my real customers?

No. Filtrex only acts on traffic it has solid reason to distrust — VPNs, proxies, TOR, bots, and known fraud signals. Verdicts are transparent and explainable, and you control the thresholds. If a genuine customer ever gets flagged, one click allowlists them and they shop normally from then on.

Will it slow down my store?

No. Filtrex screening is lightweight, returns sub-second verdicts, and adds zero checkout friction for clean visitors. The risk check runs in parallel with the page render, so shoppers barely notice it.

Which Shopify plans does it work on?

All of them. Filtrex combines storefront App Proxy screening with a Shopify Function (WASM) for checkout validation, and this combination works on every Shopify plan — no enterprise upgrade required.

How accurate is the risk scoring?

Filtrex combines five weighted signals — country risk, anonymity network, bot detection, historical fraud, and timezone mismatch — into a transparent Low, Medium, High, or Critical verdict. The weighting is visible and each block can be explained and tuned.

How do I customise the block page?

The block page designer ships five templates — glassmorphism, minimal, alert, dramatic, and split — plus per-block-reason message overrides, so blocked visitors always see a page that matches your brand.

Is merchant or shopper data stored?

Only what's needed to generate fraud signals is retained — nothing more. For full details on what we collect and how it's handled, contact us and we'll share the policy.
