What is the of usage VPN ?
- You can use it to change your IP address so you can watch the censored content in your region and you can get anonymous from your government or your ISP
Protection
Protection is the very essence of the VPN. When you are connected using a VPN, your computer or device becomes invisible to the rest of the internet. Bots, viruses, trojans and hackers which inhabit the internet simply cannot attack you, because you do not “exist” for them. If you are not using a VPN, you are especially vulnerable when you connect to the Internet via an open Wi-Fi network in the airport, coffee shop or any other public place. Because an open Wi-Fi network is unencrypted and unsecured, attackers may gain access to everything stored on your computer (e.g., important passwords) without any serious effort. They can even intercept your session with your online banking site and transfer your money to their accounts while you have your coffee. However, none of this is possible if you are connected to a VPN – for your attackers, both you and your connection do not exist.
Anonymity
Whenever you are connected to the Internet, you are assigned an IP address–a numerical combination that is essentially similar to a regular street address. With an IP address, you can be tracked down as easily as with a regular street address. You will be amazed how much one can learn about you; just visit this page: http://addgadgets.com/IPaddress/.
Many people do not like that level of access, so they use a VPN, which replaces their real IP addresses with the IP address of the gateway, which can be located in a different country.
Some websites, such as Hulu Plus, Netflix, Amazon Prime, Vudu, CBS, Spotify, Pandora, and many others, first check your IP address. If you’re not in the U.S., for example, they prevent you from accessing their services. Therefore, many people use various VPNs based in the United States so that the above-mentioned services do not see your real IP address but instead see the one in the U.S. (that belongs to the VPN) and unblock your access. In fact, this is a serious headache for many Internet users, especially for U.S. citizens abroad. Imagine what a respectable American citizen traveling abroad must feel when he or she finds out that his or her access to movies and TV series (on Netflix, Hulu, or Amazon) has been blocked, even if it has been paid for in advance.
But you should see the privacy of the VPN because some of the VPNs may sell your personal information
