Don't worry, At TechFeral, we are here to help and brought a short guide on What is a VPN and where to find the safe and most reliable best VPN for free as well paid.

If you still wonder what a VPN is, how it works, where you can use it and which one to choose, you've come to the right place. And please don't bother about the technical parts!

Let's begin, shall we?

What is a VPN (Virtual Private Network)?

Virtual Private Network (VPN) is a type of private network based on the backbone of a public network such as the WAN (Wide Area Network) or the Internet.

                                                 In today's digital world of 24x7 always-online work culture, the majority of users of this concept or technology are organizations of mid to large sizes and segments that use VPN to allow remote offices and employees to connect securely to their private network, using conventional Internet connections (public or private or leased line circuit).

The concept of VPN originated from two requirements:

1 -  To replace conventional private lines with financially viable technologies that allow connecting people or employees and business units at a low cost.

2 - Use old and less secure communication networks to share data or information more securely.

If you think as a free-mind internet user like you and me, let's have a look at How do things work in practice?

VPNs are very useful in many online kinds of stuff. Not only VPN do provide better security and privacy for you and your devices, but they can also help you avoid censorship and access geographically blocked content on the Internet from anywhere.

Let's have a few cases of practical life:

Case 1:

If somebody wants to access Netflix USA from abroad or watch television broadcasts from other countries, or simply be an advocate of an Internet without borders, a good VPN with an excellent list of servers and high speeds will completely open up new worlds of entertainment to enjoy it.

Unblocking Netflix, Amazon Prime Video, BBC, Hulu, and Other Geo-blocked Content.

Case 2:

Most organizations use VPNs so that their employees can commercial applications, and access files, printers, and other resources on the VPN network through secure remote access.

other cases:

In addition, many people who value your privacy, like to use virtual private networks to minimize exposure and stay protected from the many threats that can be found online.

Simply needs a way to avoid censored content in their country or geographical restrictions on transmissions and services abroad.

Whatever the case, the bottom line is that VPNs help improve the freedom of access of the Internet use.

Why do we need a VPN service?

  • A virtual private network (VPN) gives you privacyencryption and protection online by creating a private network from a public Internet connection or over an unsecured Wi-Fi access point.
  • VPNs mask your Internet Protocol (IP) address so that your online actions are virtually impossible to track.
  • Browsing the web or making transactions over the internet anonymously and privately.
  • The encryption and anonymity that a VPN provides help protect yourself from online activities like online buying, sending emails, or paying bills.
  • Mask your location- By using Virtual Private Network, you can select the country of origin for your Internet traffic.
  • Access blocked websites:  VPN can bypass the restriction or censorship imposed by governments and you can access blocked websites easily.
  • Virtual Private Network Security:
    Security over the network is the main reason why organizations are using VPN for years. VPNs use advanced encryption protocols and secure tunnel techniques to encapsulate all online data transfers. The constantly evolving security threats and the growing dependence on the Internet make a virtual private network an essential part of integral security.

Integrity checks ensure that no data is lost and that the connection has not been hijacked. Since all traffic is protected, VPNs are more preferable compared to proxies.

How a VPN (Virtual Private Network) Works?

Let's have a look at how your connection to the Internet would work if somebody uses a VPN for an internet connection:

  • To use a VPN service, he or she has to use a VPN app to connect to a VPN server through a VPN tunnel before you are exposed or has access to the public web. Incoming traffic is sent to your device through the VPN server and the client through private networks over the internet. That is the essence of how VPN connections work.
  • As an encrypted "tunnel" is established between users pc and the VPN server, your ISP (or anyone else) cannot sniff your traffic and data online. In addition, the VPN server will replace your IP address (provided by ISP) with a new one, once the connection is established, effectively hiding your geographic location online.
  • In general, unlike accessing the web without a VPN, doing so with a VPN guarantees that you can enjoy private browsing, the peace of mind of knowing that your personal information is protected and unrestricted access to any content (since hiding your IP address means you can avoid annoying firewalls and ISP blocks).

Here is a brief overview of the entire VPN process:

  1. Use the VPN client or app to connect to a VPN server. When you do that, the client begins to encrypt your data.
  2. The VPN client establishes a connection to the appropriate available server through ISP and configures the VPN  virtual secure "tunnel".
  3. The VPN server replaces your IP address with yours (hides user's geographic location), begins to decrypt the data it receives from users and routs its connections to the web.
  4. Once the VPN server receives the online data you requested from several web servers, it encrypts and returns it to your device through your ISP.
  5. When the VPN client receives incoming traffic from a VPN client, it decrypts it for you.

Setting a VPN on your PC and smartphone

Setting up a VPN is a simple process. It is often as simple as entering a username and server address. Dominant smartphones can configure virtual private networks using PPTP and L2TP / IPsec protocols. All major operating systems can configure PPTP VPN connections.  

On PC or Laptop:

There are two ways of installing and configuring VPN in the PC or Laptop :-

1. Downloading and installing VPN setp.exe file and installing on PC.

2. Or you can install a VPN extension in the browser (Chrome, Safari, Firefox, etc) itself.  

On smartphones or tablets or i-pads:

Download VPN apps form app stores and simply install them.

VPN protocols

One of the most important parts is to choose the correct VPN protocol. The number of protocols and security features available continues to grow over time. The most common protocols are:

Most VPNs use one or more of the following protocols: PPTP, L2TP, SSTP, IKEV2, and OpenVPN. In general, you can easily switch between them through the configuration menu.

As a general rule, use OpenVPN whenever possible: it offers the best balance between speed and safety.

How Does a VPN Guarantee Privacy of end-user?

You may wonder how you can enjoy complete anonymity when your VPN provider basically replaces your ISP as the watchdog of your Internet traffic. That is a valid concern, and the answer is that you can never be 100% anonymous, even with a VPN.

No-Logs Policies:

It is crucial to understand that privacy is not equal to anonymity, and there is a big difference. No matter what, your VPN provider can view your activity online. Unless it works under a no-logs policy.

Many VPN services with strong privacy promise that your connection and bandwidth data will never be collected, stored or shared. This means that your zero-registration VPN provider cannot delve into your confidential information. In addition, the lack of records will prevent your data from being delivered to the authorities, if requested.

In summary, a non-registration policy is a mandatory feature of any VPN that claims it can improve your privacy.

VPNs vs Proxy Servers

You might wonder why you should choose a VPN instead of a simple proxy server to access geo-blocked content, for example. A proxy server is an intermediary that masks your IP address on the Internet, doing nothing to protect your data. If changing the IP address is the only task you are looking for, a proxy may be a good option.

However, a VPN will change your IP address while encrypting your information. You can consider it as a two-in-one service.

For more information on the difference between the two and decide which one to use, you can consult our VPN vs proxies guide.

VPN and Tor

Tor, also known as The Onion Router, is an anonymous network that sends its data through at least three relays before reaching its destination but has its limitations. That is why if anonymity is particularly important to you, it is a good idea to use a combination of VPN and Tor.

There are two ways to do it:

Tor over VPN

In this model, it connects first to your VPN and then to Tor; in this way, third parties who may be spying on your connection will not be able to see that you are using Tor (which could arouse suspicion).

VPN over Tor

When you connect to Tor first, your data enters Tor, it goes through an exit node and then is passed to a VPN server.

Are VPNs are legal?

The short answer is yes! Citizens in most countries have a legal right to privacy, and VPNs do not violate any laws as pieces of software, so, in essence, their use is rarely illegal.

While VPNs are generally legal, there are several countries that try to actively monitor and restrict them. It is also important to know that, in most cases, it is not about whether you are using a VPN or not, but what you are using it for.

Some countries (such as China, Russia, and Iran) do not prohibit the use of VPN, but there is a catch. Technically, you can only use government-approved VPN services.

This means that approved providers have probably met the requirements against privacy and censorship, which makes their VPN services useless for many.

The United Arab Emirates is another notable example, where the threat of jail is added in addition to the six-figure fines. But, contrary to popular belief, the use of a VPN in this country is not totally prohibited: what is prohibited (and punishes) by law is to use one for "illegal purposes." These range from the game and hate speech to access Skype and Wikipedia, so, as you can see, it is quite easy to commit a crime with a VPN according to UAE law.

Other countries such as Iraq, Belarus, and Turkmenistan go even further by completely banning the use of a VPN. Whether to curb the terrorist presence in social networks, establish political control or simply restrict access to foreign media, the online privacy of citizens in these regions is severely restricted by law.

What is the main takeaway here? With the exception of some extreme cases, the use of a VPN is perfectly legal. However, some countries have unique requirements and restrictions on what VPN to use and what to use them for.

If you are planning a trip to Russia, China or the Middle East, it is important to familiarize yourself with the way VPNs are treated within the legal context of these countries. Otherwise, you probably have problems.

In the market, there is a lot of VPN services are available. Unfortunately, such plenty of options can also be very confusing and difficult to choose the right VPN for you. Don't worry! You can find the right VPN for you if you set your priorities directly. Let us help you with that.

What should you be looking for in a VPN?

What should you be looking for in a VPN?

It may seem that people get a VPN for " security & privacy and," but such a statement does not really help with their choice. Also, you know that VPNs can do much more for you. The fact is that VPN users are different in their needs and preferences. Now it is clear that it's up to you to find out why exactly you want a VPN.

  • To surf the Internet and public wi-fi safely and privately

You can opt for a low-cost VPN or free VPN service if you are a casual user who needs simple protection without frills, or you can take a look at the best services if you want excellent performance and a host of features. In any case, do not compromise your privacy and be sure to choose a provider of zero records.

  • To eliminate strong censorship

If you are planning a trip to China, you probably don't want to deal with the Great Firewall there. To avoid VPN crashes and access your favorite websites and services from regions with serious censorship, you need a VPN that offers concealment and stealth settings.

  • Unlock popular broadcasts

Many use VPN to unblock Netflix from abroad, and that requirement may take priority over any other feature. However, Netflix and other popular streaming platforms have made it extremely difficult for many VPN services to gain access without being detected.

  • To download torrents 

Not all VPNs support point-to-point (P2P) connections on their servers and even some that are not ideal for torrents. What you are looking for here is a good variety of P2P servers near your actual location. And like transmission, torrent is an intensive task of bandwidth, so your VPN must also be fast.

VPNs are available for almost all major platforms, including desktop computers, laptops, smartphones, and tablets. While some VPN service providers will limit you to one device at a time, others will allow you to simultaneously connect several different devices to their servers at the same time. Pay special attention to this if you need multiple simultaneous connections.

Q6.How good is the customer service of the supplier?
When reading customer reviews and ratings for each VPN service provider, you can choose a provider that responds to your queries or concerns in a timely and professional manner.

Q7.Does the provider offer a free trial?

Q8.Does the provider offer cross-platform support?
To easily use the VPN on any device, find out if the service website offers native customers. If not, you will want to get clear instructions for manual settings; make sure your VPN has them.

Q9.Are there additional features or advantages?
Last but not least, some VPN features are essential, and you absolutely must have them. The main elements of your list are the interrupt switch and DNS leak protection. Others, such as hidden configuration, double encryption, static IP addresses, and split tunnel, can be useful, depending on your needs.

  1. Good article for new VPN users. Good and quality content for new beginner with VPN. are you new to VPN? “No worries – everyone has to start somewhere!”

  2. Free ones are not trustful, and they definitely log, but I’m a student and I can’t afford an expensive service, so I've landed on Nordvpn which is offers great service for a decent price. Also found this discount on reddit, maybe still works:
