Blockify Fraud Filter for Shopify — Usage Statistics

Install it before the fraud actually hits. Chargebacks and reserve holds are the punishment side of the fraud equation; the preventive side is cheaper. A store that starts thinking about fraud only after its first big wave pays for that delay. Chargeback fees and lost inventory usually cost more than the subscription would have. Blockify's free tier gives you the country-block and IP-block basics; the paid tiers add the higher-signal detection like proxy and VPN filtering.

Country blocking is a blunt tool. Use it deliberately. Blocking a whole country solves obvious problems (a store not licensed to ship there) but also throws away real orders from legitimate customers on VPNs, expat shoppers, and travelers. Before turning on any country block, run through the order log for the past few months. Check whether the fraud you saw actually came from that country or just correlated with it. A geo-block against a legitimate diaspora costs revenue, and it costs quietly.

Layer it, do not lean on it. Blockify is a filter layer that runs before payment. It catches proxy IPs, high-risk countries, and known bad actors. But it is not a substitute for the fraud tools your payment processor already runs, and it does not review disputed transactions after the fact. Pair it with strong 3D Secure rules on the payment side, an AVS/CVV posture that matches your risk tolerance, and a manual-review queue for the borderline orders your processor flags. Blockify is the front door; the payment processor is the safe.

Read your own logs before writing rules. Blockify's power comes from its rules engine (block by country, IP range, device fingerprint, or order signal) but rules only work when they match your actual fraud pattern. A store getting hit by card-testing bots writes different rules than a store getting hit by cross-border chargebacks. Spend an evening in your rejected-order log before you configure Blockify, and you will end up with a tighter policy than any default template gives you.
