The Virtual Private Network is a service that ensures the security of your Internet connection.
How to intercept online communications:
- a) The easiest is when you use a public wi-fiwithout a password. Anyone in the signal range and having a specially equipped computer can intercept the transmission.
- b) Even if the wi-fi service is password-protected, when the password is relatively public (for hotels, restaurants, etc.), it is almost as easy for the hacker.
- c) Even though it is not public, it can be stolen or broken by a hacker.
- d) Even if the system is secured to external attacks, the wi-fi service provider has access to the content that transmits it.
- e) If the owner of the wi-fi is trusted, the Internet Service Provider (ISP) has access to the data anyway.
- f) Even when ISPs protect your data, it can still be stolen – by private or state actors.
How a VPN works
When you use a VPN service, access is via a remote IP, use a secure connection to your computer or phone. The sites you access only see the VPN IP and any intermediary on the route, either appealed or uninvited, sees at most an encrypted data stream.
Almost the same result you get if you connect to sites that provide an SSL connection. You may have heard about VPNs, but you probably did not use this type of service until now. Well, we have to tell you that you should use a VPN as quickly as possible. At first glance, you may not see the true value of such services, but over time, you will find that VPNs are just as important as internet connections. In this article, we want to explain what a VPN is, how it works, and why it is useful for you.

So why would you still want to use a VPN?
You want to keep confidential the data you send and receive on the Internet. If you work with sensitive information (“you have something to hide”, as it is in popular language), VPN is virtually indispensable. The advantage is that you can turn it on or off as needed, or you can alternatively use multiple separate VPNs as needed.
You want to make maximum use of geographically restricted services such as Netflix or Hulu. Attention, the two services have a policy of discouraging VPNs, so they do not all work for that, and none can guarantee that it will work in the future.
You want to file-share in relative security through services like DC ++, BitTorrent or Popcorn Time. Downloading content on the Internet, whether licensed or not, is not prohibited by law. However, when the downloaded files become available to other users – with or without intent – you risk becoming a criminal.
You want to bypass the access restrictions imposed by your employer. Some companies or state institutions have restrictions – more or less reasonable – on the content that can be accessed. Likewise, employees may have more or less reasonable reasons to prefer to circumvent these restrictions. Here are some helpful hints: https://www.bestvpn.com/vpns-beginners-need-know/
In some ways, how a private virtual network works is similar to a typical proxy, as your ISP only sees the connection to the proxy and, by default, the proxy server is the source of your access requests. However, unlike a VPN, a proxy connection can easily be monitored by your ISP because it can see the access requests made by you to the proxy, as they are not encrypted. In other words, with a simple search, all your online activity is still visible.
VPN software components are available for creation and maintenance of tunnels either between two security gates or between a customer and a security gate. These solutions can run on existing servers, thus dividing resources with them. It is the most suitable solution for client-to-LAN connections. Basically, a software application is installed on the client’s computer which establishes the connection to the VPN server.
Please note, however, that a VPN does not provide full anonymity – for this, you can use the Tor browser and the TAILS operating system more suitable. The VPN also substantially reduces the connection speed you were used to – up to 50% or even more!
