I use free VPN combined with my data. I recommend TCPVPN because it transmits data that was encrypted so that secure and remains confidential even though sent over a public network. To ensure security and data connections, TCPVPN employs several security methods such as : Firewall, Encryption, IPSec, AAA Server. The company operational costs that provides my data will also be reduced when using VPN. Thumbs up for this.
