VPN Shield monitors connection quality to protect user information and to ensure maximum browser efficiency. The app lets you communicate with public networks as if the connections were private. Users must specify the country whose network they are connecting to, based on the recommendations made by VPN Shield, prior to establishing a connection. VPN Shield warns you if your connection is potentially not safe and encrypts all communication that is sent to its secure servers from your devices. VPN Shield hides device IP address and location to create anonymous Internet browsing. Its newest version offers IPv6 support and VoIP calling.
