Virtual server appliance
A G/On server is made up of one or more G/On gateway servers and the G/On management server. It provides all the functions needed for secure user access to their applications without the complexity typical of VPN environments. This brings with it vast scope for simplifying IT structures and cutting costs.
In terms of technology, the G/On server is a port-forwarding proxy with an integrated firewall, that runs at application level and supports a protocol at the same level for communication with the G/On clients.
Unlike a standard Network Admission Control (NAC), G/On does not provide access to the network. In fact, the G/On architecture is structured so that detailed information about end user devices is collected and used as part of a complete decision-making process for authorization (device authentication).
A 2-factor authentication process with hardware tokens ("something you need to have") plus user name/password ("something you need to know") is used with G/On. Authentication takes place online with random factors that are generated by the server and cannot be calculated, intercepted or spied on (unlike a PIN or OTP).
