For shopify merchants hit by fraud
Blocks countries, VPNs and bots on your storefront, and holds risky orders before they ship.
Portcullis has two gates. The storefront gate decides who may browse: blocked or allowed-only countries, single addresses and ranges, VPNs, proxies, Tor, data-centre networks and bots reading faster than a person. The order gate scores every order and holds risky ones before anything ships, with every point explained. Watch mode at install shows what a rule would have stopped before it blocks anyone. Your allow list and paying customers come first, and real search engines are never blocked.

The problem
Portcullis has two gates.
The incumbent, Kedra Fraud Filter & IP Blocker (re-opened 2026-10-16: 4.3 stars from 103 reviews), blocks countries and addresses free, and puts VPN, proxy and bot detection behind $7.99 a month — $12.99 on the Shopify plan and $22.99 on Advanced and Plus. Its own reviews name the fear: a foreign customer on a corporate VPN, blocked. Portcullis is built around not doing that:

What happens to my data if I uninstall?
