What is a VPN? A virtual private network creates a secure tunnel between two sites via the Internet to protect your privacy. This is usually a paid service to ensure web browsing is secure and private while using public wifi or less secure wifi networks.
What happens? Your PC connects to a VPN server, and then your web traffic passes back and forth through that server. This VPN server can be located anywhere in the world whether it be the United States or Thailand. Therefore when you are surfing the web, those websites you are visiting see you as browsing from that VPN server’s geographical location, not where your laptop is really located.
Why is that important? When you are hanging out on your laptop in a public space such as a coffee shop, perusing Amazon for some deals, hackers are far less likely to be able to steal your login credentials, your credit card information, email address, or direct you to a fake banking site or other spoof. Even your internet service provider will have a hard time trying to snoop on what websites you are visiting.
Free services are offered, but they are slow with considerably less bandwidth, so pay the $5 a month and get a service of quality. Ask questions such as what kind of logging does the VPN provider do? How long do they keep information about your VPN sessions? Are they going to be recording the IP addresses you use? Answers to these questions should be taken into consideration based on how much privacy you want and need.
