Security gateway SG6 series

industrialModbus TCPVPN

Security by encrypted communication and cross certification Authentication without using login ID/password HTTP server can be operated as HTTPS server Certificates can be generated by using LCA-SG Local Certification Authority Creater. Basic industrial protocols such as Modbus/TCP with no authentication or encryption system, need other means such as VPN (Virtual Private Network) to secure communications via the internet, which may be costly and over performance it if is employed only for Modbvus/TCP. A pair of SG6 placed at the gateway to the internet provide TLS (Transport Layer Security) to common but vulnerable Modbus/TCP, SLMP or HTTP. Security of a currently running system can be easily upgraded by introducing the SG6.
