All of the illustrated solutions can be active in a SiteManager at the same time
On-demand Access - for Maintenance and Programming

This is the primary and most unique functionality of the Secomea Industry solution.
The purpose is to provide multiple technicians programming access to devices at multiple sites.
Who has access to what, is centrally controlled by the technician's LinkManager account on the GateManager, on which all access is logged also.
No fixed or public IP addresses are needed, and all connections by SiteManagers and LinkManagers are inside-out and using standard Web based SSL/TLS protocols, thus making the solution extremely firewall friendly. Watch Movie
Permanent Access - for Secure Data Logging

This feature allow you to make static connections between devices behind SiteManagers at different locations. This is an easy method to e.g. allow a log server to collect data from devices, and is typically used for utility installations.
The setup can be based on either a Device Relay or a Server Relay, depending on whether the devices should push log data to the server, or the server should collect them from the device. The setup is based on vitual IP addresses,which means that subnet conflicts will not occur. In fact all devices could have the same IP address.
Just as the solution above, this setup is based only on inside-out web based SSL/TLS connections, which means the it is extremely firewall friendly.
Note: if your need is for video streaming or full tunneling, you should consider the solutions below.
Permanent Access - for Secure Data Logging and Video with own GateManager Server

This setup is using the same relay principles as solution 2, but is based on the GateManager server being installed at the same site as the server.
The advantage is that you can now use the relay connections for bandwidth intensive data, such as Video.
Similar to a VPN Concentrator, the GateManager server needs to be accessible on a public IP address, but the server itself could be placed in a DMZ or behind a firewall that NATs connection to the GateManager.
As above the setup is based on vitual IP addresses,which means that subnet conflicts will not occur and all devices could have the same IP address, and the solution is based solely on web based SSL/TLS connections, which means the it is extremely firewall friendly.
Permanent Access - Full Network Access for Maintenance and Surveilance

This feature is used for having central services simultaneously monitor multiple devices at different sites.
Although it resembles an ordinary VPN infrastructure, it makes use of the Secomea EasyTunnel VPN concept and includes a Secomea TrustGate EasyTunnel concentrator.
EasyTunnel is just as secure as ordinary AES/x509 IPSec based VPN, but enable users to create tunnels with single clicks and without any networking skills.
Direct Internet Access - for Data Logging and Video Surveilance

This feature is enabled by the SiteManager Forwarding Agent. Basically this allows a device to use the SiteManager as an Internet gateway for sending log data to a web service.
Or it can be used by e.g a video surveilance system, which connects to the IP address of the SiteManager that in turn forwards the connection request to a specified port on the device (This will require the SiteManager to be assigned a public IP address, and is typically used for 3G/GPRS connected SiteManagers, with a fixed IP address ISP subscription).
