2019’s Best VPN Providers
VPN stands for virtual private network. When you connect to a VPN, all the data that gets sent from your device to the private network at the other end (and back) is "encapsulated." Each packet of data gets put inside another packet -- think putting a letter into an envelope to keep its contents from being read during transport. The envelope could still be opened, though. That's why organizations like the CIA put tamper-proof tape over the flap. With a VPN connection, encryption is the tamper-proof tape. Some VPNs use SSL for encryption (just like secure websites do). Others might use IPSec or PPTP.
