Cordon: VPN & Country Blocker

Cordon: VPN & Country Blocker is a Shopify App designed to block bots, scrapers, VPNs, and country fraud before they reach the store. It allows users to select countries to block, set allow rules for trusted IPs, and detect various unwanted traffic sources such as VPNs, proxies, Tor exits, datacenter networks, bots, and headless scrapers. The app ensures fast decision-making in under 50 milliseconds per visit and fails open if the service is slow, allowing real customers to shop normally. Visitor IPs are securely hashed for privacy protection.
