Fraud costs you twice: the product and the chargeback fee. GateKeeper stops it at both doors. On the storefront, block visitors by country, IP or CIDR — plus Tor, VPN, proxy, datacenter and bot traffic — before they reach checkout. In the back office, rules act on risky orders the moment they land: fraud risk level, COD, order value, country mismatch, first-time buyers. Fail-open by design, with a live rule tester and a full activity log showing what was blocked and why.

• Block by country, IP or CIDR — blocklist or allowlist-only mode
• Stop Tor, VPN, proxy, datacenter and bot traffic before checkout
• Auto-cancel, hold or flag risky orders the moment they come in
• Rules on fraud risk, COD, order value, country mismatch, new buyers
• Fail-open safety, live rule tester, full block + order activity log
