TOSIBOX® Lock 200

TOSIBOX® Lock 200 is an intelligent remote access and networking device that serves as an endpoint for secure remote connections. Devices connected to the Lock are securely accessed over the Internet and most LAN and WAN networks through an encrypted VPN connection. NAT and firewall friendly, the Lock’s patented Plug & Go connection method takes you out of the box and into use in less than 5 minutes, without the need for software installations, network configurations or special skills.

TOSIBOX® Lock 200 is especially designed for industrial environments and its robust housing offers better installation possibilities e.g. on DIN rails.
