An essential function of equipment deployed in the field is accessing these devices securely.
Devices such as routers always require software upgrades or maintenance to fix newly discovered security vulnerabilities.
Often this requires a VPN solution at the customer site. Or that each router connects as a client to a central management system using VPN.
The should be no situations where equipment is directly exposed to the internet. Such a solution is fraught with troubles down the line.
The NODA routers provided by Teltonika solve this problem by providing a secure connection using secured MQTT as a transport layer. The device connects to Teltonikas Remote Management System (RMS), where all devices are accessible and easily managed.
