What is a VPN service?


What is a VPN service? The technology described.

What is a VPN service? The past, the present and… the future.

Let’s face it, the Internet has an important role in our lives. Just like any other regular thing we use, we have to handle this tool with a lot of care. Being irresponsible while using the Internet might put us in front of serious online threats.

The VPN technology was continuously developed to compensate for the Internet’s lack of security. Nowadays, one out of four internet surfers use a VPN for various reasons.

For a better understanding of this concept, we’ve put together this comprehensive article where we’ve described what is a VPN service, how it works, its advantages/disadvantages and many more useful information.

The VPN technology – The conception.

Nowadays the VPN technology is used mostly for privacy matters by a significant number of internet users.

At the very beginning, before VPNs became popular, this privacy solution was mostly used within large companies. The technology allows remote users and branch offices to access in a secure way all the corporate applications, other resources, and documents. The secure connection is granted by the tunnel that the VPN creates and the encrypted connection.

Not long after VPNs became mandatory for companies, internet users started to recognize the real advantages of the technology.

From a software implemented by the large corporations, VPNs turned to be indispensable for any internet user concerned about online privacy and freedom matters.

What is a VPN service and what makes it so popular?

A VPN (Virtual Private Network) is a technology that is able to extend a private network across a public network.

In other words, a VPN will create a secure tunnel between your device and the final destination on the web. This tunnel will securely guide your data to its destination.

A common definition that every Internet user can understand, no matter the technical knowledge he/she has, is that VPN is a safe communication method between two points through a public network.

What is a VPN service and how does it work?

The main components of the VPN are the VPN server, the VPN protocol, and the encryption.

For your VPN connection, the VPN server works like a bridge between your device and the internet. The VPN server is actually a combo of hardware and software technologies.

The VPN protocol and the encryption level are also very important.

A VPN protocol combines different encryption standards for data transmission between your device and the VPN servers. There are many VPN protocols used, but each protocol has its advantages and disadvantages. If some protocols can prioritize your speed, others are less fast but super secure.

The encryption component of a VPN is a process of encoding the data transmitted over the internet. There are different encryption standards and one of the most powerful and used by VPN providers is AES.

How does a VPN work?

What we’ve understood so far?
The VPN stands like a protection bridge between your device and the internet.
The real question is how does the VPN technology create this private scope of communication?

In the first instance, you connect to the VPN client via the VPN server. Right from this point, the VPN client encrypts your traffic and sets up the VPN tunnel (or the VPN tunnels, if we speak about Double VPN).

During this process, the VPN will replace your real IP address with the one that belongs to the VPN server you chose to connect to.

At this point, the VPN server is able to hide your real location and is at the phase where it directs your connection to the destination server.

As soon as the destination is reached before it sends all the information back to you, the VPN reads it, encrypts it and, after that, it decrypts it so you’re able to read it too.

The whole process is pretty tangled, but it happens in the blink of an eye.

Why is VPN so popular among internet users?

Right after understanding the whole concept of the VPN and its pluses, is really easy to understand why is used by more and more people every day.

In practice, the VPN is able to do more than remotely access various files in a secure way or help you stay anonymously online by changing your real IP.

Hare are some things you can do with a VPN:

  1. Enhance your online security. People’s online privacy is put under scrutiny these days. If a private network is not safe, just imagine which are the threats behind a public WiFi network. Traffic encryption is mandatory while sending sensitive information over the web.

  2. Enhance your privacy while using Tor. Tor over VPNTor over VPN is a solution that helps you take your online security to a whole new level. Basically, when combining Tor with a VPN you make sure your ISP is not able to see your online activities, as your connection is encrypted by the VPN. This is an important thing you should do, as Tor is not very safe and accessing Onion websites often can put you under surveillance.

  3. Unblock geo-restricted websites and bypass filters. The VPN technology is able to help you gain access to websites that are restricted to some locations. Also, another problem that internet surfers might face is traffic filtering. In some countries, the government regulates the internet traffic and blocks any internet connection that uses a VPN. By using VPN and technologies like Stealth VPN, Shadowsocks or Socks5 proxy, you can forget about deep packet inspection and internet censorship.

  4. Avoid bandwidth throttling. This “bandwidth chocking” technique helps your ISP minimize bandwidth congestion. Normally, your ISP is able to see all your online activities and, for example, if you’re a heavy streamer of a torrent downloader, your ISP can throttle your bandwidth. By using a VPN service, you will keep your online activities private and your bandwidth untouched.

The disadvantages of a VPN.

The advantages of a VPN are responsible for all the buzz the VPN creates and rightly so, we can understand why.

However, the VPN technology has its downsides too, like:

  1. A good VPN is not free. Of course, after a one-minute search, you can find plenty of free VPN service. We highly recommend you not to take into consideration such services as they represent real threats. For example, such internet providers sell data related to their customers to third-party companies for certain reasons. And, between all the horrible things that could happen, this is the most pleasant one.

  2. A VPN service can affect your internet speed. In general, your internet speed is affected by many factors. When you use a VPN, you can affect your speed and this thing can be caused mainly by the VPN protocol. For example, SSTP is a super-secure VPN protocol but, because it uses a high level of encryption it might affect your speed. On the other hand, PPTP (Point to Point Tunneling Protocol) is a fast VPN protocol that doesn’t affect your speed but it doesn’t protect your privacy either. The best thing to do it to take speed tests and check which VPN protocol is better meeting your needs.

  3. Some VPN providers can keep connection logs. Even if you opt for a paid VPN provider, you can face this unpleasant situation. Before subscribing to a VPN provider, make sure you check their privacy policy so you can make sure nobody spies on your activity.

  4. The complexity of a VPN. If you’re at the beginning of your VPN journey, you might find VPNs a little bit complicated. The multitude of features, types of servers or VPN protocols can put you in the situation where you won’t understand a thing. Still, there’s a blessing in disguise. A trustworthy VPN provider should have a support team always ready to assist its customers in solving their issues or having their questions asked.

How to choose a VPN service?

After reading the article till this point, we can say that you’ve made a solid idea about what is a VPN service.

One thing is for sure – using a VPN service is necessary these days. Here is a checklist you should take into consideration while looking for the best VPN provider:

  • Customer support. Even if you’re a tech-savvy you might need support so, the technical assistance is an important matter you should take into consideration. Having your questions asked within minutes by a friendly tech department is a total delight.

  • Privacy policy. If you don’t want your ISP to spy on your online activity, then why would you want your VPN provider to do it? Makes sure you choose a provider with a clear and transparent privacy policy and that keeps NO logs on your activity.

  • Look for a provider that allows a free trial. Reading reviews about a VPN on tech-related websites can help you. However, the performance of that VPN service can be less satisfying than the one described in the article. This doesn’t mean that the reviews are lying but the performance of a VPN can be influenced by many factors like your ISP, your own device and many more. A free VPN trial will help you test the VPN on your own so you can make sure it meets your needs.

And this is not all…

You still have to look for:

  • Servers’ location. The servers’ location is important especially when you want to use a server from a certain country. So, before subscribing to a provider, double check that it has a generous number of server locations.

  • The VPN apps. Yes, is true, you can manually set up a VPN connection on your PC or mobile device yet, using a VPN client is easier. For instance, a VPN client for Windows usually comes fully-featured, with all the servers and protocols in the same place. For an awesome online experience, while using a VPN, we definitely recommend you to take in consideration the VPN client for your device.

  • Last but not least, check their own reviews page. Knowing what the actual customers of a VPN service have to say about the performance of that VPN is super helpful. So, if your future VPN provider has its own reviews page on the website, make sure you throw an eye on it.

In an internet era where the Wi-Fi networks have serious privacy issues and expose a lot or your online data without your knowledge, the “mobile VPN” will be mandatory.

It’s not enough to use a VPN on your PC or laptop. You should protect the traffic generated via your smartphone too.

Using a VPN on the phone is as simple as you can see in the video above.

Hand in hand with the cyber-attacks, the number of governments that will start to regulate traffic and require online restrictions will grow. Each year, more and more countries adopt different internet censorship measures that restrict users from surfing free.

In the end, we want to ask you a question:
Would you allow your neighbor to read your correspondence?
No, right?
Then why would you allow your ISP or other third-party companies?

Let’s make the online world a better place by helping VPN technology receive the awareness it deserves.
