VPN networks are becoming an increasingly popular solution among companies and private clients. Many people connect to the Internet using the “Virtual Private Network”, because it allows us to hide our identity and thus increase security on the Internet. What are the other features of the VPN? What are its pros and cons?
What is a VPN and how does it work?
VPNs are non-public networks that act as a tunnel connecting computers to the public Internet. Using a VPN client, we connect, using an encrypted connection, first to a special server, and then to the Internet, already at a changed IP. This means that the websites we visit do not see our identity, but only get information about the VPN server we use.
This connection is quite secure, as the packets sent are encrypted on the fly and even if they are taken over, there is not much to do with them. The cipher keys are encoded on servers and change regularly, which is why it is almost impossible to trace our history on the Internet.
What is the VPN for?
VPN servers are used by people primarily to hide their identity on the Internet. Why share your IP address with visited sites if you can easily mask it?
Of course, this is not the only profit of using a VPN. Streaming services such as Netflix block some content from people in given countries. In order to bypass this blockade, you must use a VPN server located in another country. So if we go on vacation abroad, in a place where the series is blocked, VPN is our only salvation.
Social network blocks work on a similar principle. Facebook and Instagram are banned in many countries and the only way to circumvent this restriction is to use a VPN.
The service of masking your identity should also be used when using public networks available at airports or cafes. Such sites are highly vulnerable to cyber criminals.
Advantages and disadvantages of using a VPN
VPN, like almost every service, has its advantages and disadvantages. It all depends on how and where the virtual servers have been shared.
A VPN enables secure internet use. By using it, we make it difficult for unauthorized persons to break into our device and intercept sent and received data.
Changing the IP address significantly improves online privacy and anonymity. By turning on the private mode in the browser, we leave fewer traces on the network.
All packets sent to and from the VPN server are encrypted, so that even if someone manages to take them over, nothing will be obtained from them.
Possibility of using services and services blocked locally. A VPN hides our real IP address by sending its own pages to visited sites, so we can check in from a different location in a few seconds.
Thanks to VPN, you can bypass Internet censorship and use the network freely in countries such as China or Iran
Disadvantages of VPN
It is not easy to find a good and trustworthy VPN. Not every company that offers a VPN service cares about users’ safety and privacy
Most free VPN services are dangerous because they usually earn their living in an unethical way (Check list of the best VPN available). It has been heard more than once that VPN owners sell their users’ data or allow others to use our internet connection.
Using a VPN usually involves a reduction in the maximum connection speed guaranteed by your internet provider.
