Our remote support software is based on UltraVNC SC, a mini (166k) UltraVNC Server that we customized and preconfigured for download by a Customer. UltraVNC SC does not require installation and does not make use of the registry. The customer simply downloads the little executable and Clicks to make a connection. The connection is initiated by the server, to allow easy access thru customers firewall.
How secure is UltraVNC SC?
The SC version is initiated by the person that shares his desktop: he needs to voluntary click to initiate the connection.
You can use up to 128bit encryption. The encryption level depends on the OS and installed MS Crypto api.
The server can only connect to the IP adress you have predefined.
No incoming connections, no unattended service connection.
SC is automatically and systematically unsinstalled when the connection is closed.
