Cordon: VPN & Country Blocker

Cordon: VPN & Country Blocker is a Shopify App designed to block unwanted traffic such as bots, scrapers, VPNs, and country fraud before they reach the store. It offers the ability to select specific countries to block, set allow rules for trusted IPs, and detect various types of malicious traffic quickly. The app ensures fast decision-making with under 50 milliseconds per visit and fails open in case of service slowdown to allow real customers to shop normally. Additionally, it prioritizes customer data security by hashing visitor IPs with a daily-rotating salt for irreversible historical logs after 24 hours.
