DMZ Gateway®

Globalscape DMZ Gateway® for EFT secures transfers across firewall boundaries without opening inbound ports in the firewall. DMZ Gateway does not store or process data. It acts as a liaison between external connections and your internal network, ensuring that your data remains safe behind the firewall for EFT to store and process. Using a two-way connection originating inside EFT, the DMZ Gateway acts as a communication proxy that replaces inherently insecure inbound connections from the Demilitarized Zone (DMZ) to your network.
