From a CNET report: A VPN redirects your internet traffic, disguising where your computer, phone or other device is when it makes contact with websites. It also encrypts information you send across the internet, making it unreadable to anyone who intercepts your traffic. That includes your internet service provider. Ha! Problem solved -- right? Well, sort of. The big catch is, now the VPN has your internet traffic and browsing history, instead of your ISP. What's to stop the VPN from selling your information to the highest bidder? Of course, there are reputable VPN services out there, but it's incumbent on you the user to "do your homework," Ajay Arora, CEO of cybersecurity company Vera said. In addition to making sure the VPN will actually keep your data private, you'll want to make sure there's nothing shady in the terms and conditions. Shady how? Well, in 2015, a group of security-minded coders discovered that free VPN service Hola was selling its users' bandwidth to the paying customers of its Luminati service. That meant some random person could have been using your internet connection to do something illegal. So, shady like that. "I would recommend you do some cursory level research in terms of reputation [and] how long they've been around," Arora said, "And when you sign up, read the fine print." From a report on Wired: Christian Haschek, an Austria-based security researcher, wrote a script that analyzed 443 open proxies, which route web traffic through an alternate, often pseudo-anonymous, computer network. The script tested the proxies to see if they modified site content or allowed users to browse sites while using encryption. According to Haschek's research, just 21 percent of the tested proxies weren't "shady." Haschek found that the other 79 percent of surveyed proxy services forbid secure, HTTPS traffic.
