![]() By aggregating user traffic through those endpoints, the providers could offer users a measure of anonymity, plus the protection of in-transit data encryption. Instead of using protected networks as endpoints, they set up geographically dispersed endpoint servers for users to connect to. In recent years, however, commercial VPN providers have used the technology differently. Plus, the business's network firewall would only allow external traffic in if it came from an authorized remote VPN connection. The user's PC would encrypt all network traffic using a key that only it, and the business network destination, had. At first, businesses used VPNs as a way to offer employees secure remote access to protected business networks while they worked from home or on the road. But they weren't necessarily intended for use as an internet privacy tool - at least not at first. ![]() The core purpose of a VPN is to encrypt data as it passes through the networks that make up the internet. VPNs Offer Point-to-Point Encryption and Anonymity Here's an overview of the data privacy benefits of today's commercial VPN services and how PIA is elevating location shifting into the next must-have VPN feature. Some, like Private Internet Access (PIA), are expanding their ability to provide location shifting and creating a whole new reason for users to turn to VPNs. And VPNs make up a data privacy market that's already worth an estimated $41 billion worldwide. It's a software encryption solution that prevents anyone from accessing data traversing the public internet other than its intended recipient. The de-facto tool most people use for that purpose is a VPN. Today, network administrators and individual internet users spend significant amounts of time and money trying to keep their data safe from prying eyes. And that probably explains why none of the researchers who thought up its core technologies - things like packet switching and TCP/IP - gave much consideration to the need to secure the data passing through it.īut by 1989, hackers like Robert Morris had already spotted the security weaknesses of the fledgling global network and started to exploit them. Back when the internet consisted of a handful of computers networked together across a few research institutions, nobody could have imagined that it would one day form the backbone of a new digital way of life.
