Unlike a VPN, it secures data from end to end, from client to server. It operates whether or not a firewall is in place. There is no need to put firewalls inside your network to secure sensitive data from those without a need to know, or to protect it from disgruntled employees. ICE.PPN enables secure use of the Internet for transmitting confidential data , eliminating the need for dedicated dial-up equipment and support, and reducing national and international long distance charges. It can also be used to build secure extranets to business partners.
Passwords authenticate the client.
Easy Installation and Operation ICE.PPN includes both client and server software. It can be installed on any unused socket. When an application using a standard telnet or FTP is started the first time, the user is asked if the connection is to be secured. Non-secure telnet or FTP connections can still use standard daemons on the server if desired. Secure connections use the ICE.PPN daemons.
