Cordon blocks unwanted traffic before it reaches your store. Pick countries to block, add allow rules for trusted IPs, and enable detection of VPNs, proxies, Tor exits, datacenter networks, bots, and headless scrapers. Decisions happen in under 50 milliseconds per visit, and if our service is ever slow Cordon fails open so real customers shop normally. Visitor IPs are SHA-256 hashed with a daily-rotating salt before storage, so historical logs become permanently irreversible after 24 hours.
