Beyond remote terminal units, the S4W remote management solution features an ecosystem designed to secure and facilitate the use of remote management networks. SG4000 is a VPN server enabling secure management of communications via the public internet (GSM or ADSL link). S4-Manager is a centralised administration tool for telemetry network users and configurations. S4-Keys, a software program for network security certificate creation, completes the system.
