VPN Watcher Monitors VPN Client Security
Virtual private network (VPN) is a network that uses primarily public telecommunication infrastructure, such as the Internet, to provide remote offices or traveling users access to a central organizational network. VPNs typically require remote users of the network to be authenticated, and often secure data with encryption technologies to prevent disclosure of private information to unauthorized parties. At some moment we can be disconnected from the VPN and we start to use the public network to transmit sensitive information without noticing the change.
VPN Watcher is an application that will solve this issue by closing certain applications from sending any data to a network when VPN connection is not working. After installing the software you connect to your VPN and launch VPN Watcher, next you add all application you are looking to use over the VPN and software will start to check VPN/Server connection at each second. If the VPN connection goes down it will stop selected applications and as a result avoid confidential data from being leaked.
VPN Watcher has both a free and paid version. The paid version (worth $9.95) provides the utility to temporarily suspend (instead of closing) restricted applications. VPN Watcher works on Windows XP, Windows Vista and Windows 7.
