What is VPN?

If you answered yes to any of these questions, you may have noticed that the Internet works like a radar that captures, stores and passes on all the activity you do on it. If you are not happy with this situation and want to browse with more privacy and security, then this guide is for you. In this video, we are going to cover everything about VPNs you need to know.

What is VPN?

A VPN (or Virtual Private Network) is an online service that helps to connect to another network securely over the Internet. To simplify, it acts as a switch that creates an encryption tunnel between you and a remote server operated by a VPN server.

  • To explain in technical terms, a VPN will encrypt your connection so all your actions will be untraceable.
  • As all your traffic will be routed through a VPN server, you will be anonymous. Since they will mask your IP address.
  • VPNs offer more security than public wifi hotspot and help you in accessing geo-blocked content in streaming apps like Netflix, Hulu, Amazon Prime, and many more.

VPN provides an option to establish a protected network connection using your network’s ISP. This will keep your private information safe as the encryption will happen in real-time. 

How VPNs Work?

VPNs work by creating a secure tunnel between your computer and the rest of the internet. This shield will protect your data when it leaves your computer.

  • VPN will mask the IP and change your location to VPN remote servers so that all the traffic will go into the VPN server first before hitting the internet.
  • When you visit a website they will see your VPNs IP, not your actual IP. As they provide encryption your data will remain safe.
  • VPNs make it difficult for others to track your details.  VPNs will boost your privacy and security while you are online.

How a VPN Works

To make it practically let’s consider a scenario if there is public Wi-Fi near airports, railways station. You will connect to them instantly without any second taught. But, you might don’t know who is watching your traffic. Is it secure?. But, if you connect to the same Wi-Fi network using a VPN you can rest assured that no one can track your internet activities. None of them can track or steal your data, nor even the network operator.

Everyone should carefully think before they are connecting to the public Wi-Fi, don’t go over with the names as they are. When it comes to the home you don’t need to worry about someone watching your data. Even here also VPN will prevent your IPS from knowing what you are doing online.

Do I Need a VPN?

VPN will be a security tool to ensure your privacy and security online. Here are a few reasons why you need a VPN:

  • Encryption: A VPN will encrypt your traffic data. So that it is much more difficult for hackers or other third party people to know what the data contains.
  • Avoid being hacked: It is relatively easy to hack on a public WiFi network. Even in private, it is also if the criminal in question has data such as IP or has managed to sneak malware into your PC. A good security measure is to hide your IP address behind a VPN, which will provide the attacker with a bogus address.
  • IP Masking: VPN will mask your IP so that the website or anyone will never know your original IP to track your details.
  • Access Netflix and Sports Streaming from Other Countries: With the help of a VPN you will be able to access the geo-blocked content in different streaming apps like Netflix, Hulu, Amazon Prime, and many more in any country.
  • P2P Sharing/Torrenting: VPN will also allow you to download the torrents so that you will get access to huge content which is not available to the open world. Since P2P is illegal in many countries we cannot access it directly.
  • Firewall Bypass: A firewall block certain websites from users. With the help of a VPN, you can take advantage of accessing Facebook, YouTube, Google, and other sites.

As you can see a VPN is offering all these features you can rest assure using a VPN without any fear. While some of the VPNs will also provide anti-malware protections.

What will a VPN help you with online Privacy?

You might already know that a good VPN will hide your IP as well as helps in encrypting your data using some of the toughest encryption algorithms available like 256-bit AES. But how does this will help in the real world?

  • Browsed History: When you surf in browsers your ISP(Internet Service Provider) and websites you visit tracks your data, where most of the data is being used for profit for companies. Also browsing history is linked to IP address as well.
  • Location: Your location can be found accurately with IP addresses. But with the help of a VPN, it becomes difficult to track the place of the device and this will also help in accessing the geo-blocked content in different streaming apps.
  • Internet Activities: Since most of the good VPNs will have a zero log policy, you will be fully secured. You can also be sure that your IPS nor the other party members will never be able to track your activities.

VPN Classification

We can classify the VPN into different ways either by the device type or for what they have been used. There are two types of VPN are Remote Access VPN and Site to Site VPN.

Remote Access VPN

If you are looking for a personal VPN for Streaming, torrenting, etc then you will end up with this Remote Access VPN. This kind of VPN will use remote servers and hide your IP to encrypt the traffic making it difficult to track by other people.

Site to Site VPN

The site to Site VPNs is composed of intranet and extranet VPNs. Those functionalities follow like below. This(Intranet) type of VPNs will be used for organizations when they have more than one branch. Since site-to-site VPNs will be stored into extranet and intranet-based VPNs. If companies want to extend their Local Area Network to another company, then they use Extranet.

VPN Protocols

Double VPN

VPN Protocols will helps in establishing a secure connection between two networks. These protocols make the VPN varies in speed, connectivity, and compatibility. While most of the VPN will support at least two tunneling protocols. But, when it comes to the desktop you will have an option to choose which protocol to enable. For mobiles, the VPN Provider will judge which protocol will be used in your Android or iPhone.

WireGuard: This is next-generation split tunneling and a new protocol in the market. This is only available in NordVPN and Private Internet Access VPNs as of now. We can expect that every premium VPN will include this in the future.

OpenVPN: OpenVPN is the most popular protocol which is supported by every VPN virtually as this one work with either UDP or TCP network protocols.

IKEv2: This is another most common protocol to add security for the device and this one will look after the transport part. While this is supported by iOS.

L2TP/IPSec:  This is the same as the IKEv2 protocol but used in iOS devices mostly. So you should avoid it as this one has Snowden leaks.

SSTP: This protocol is created by Microsoft and works only in windows which makes this less popular and this can pass firewalls pretty easily.

PPTP: This is totally outdated protocol that is not secure and you shouldn’t use this. This is also developed by Microsoft when Windows 95 are the trend.

What is a Double VPN?

What is this double VPN sounds crazy right? By the name reflects that a double VPN will create a dual connection instead of one. For example, if you want to reach a server in the US then you will be redirected to the UK first and then the USA. If you are still confusing that, what’s the purpose in doing that. Well, it makes it really sweat to track you down.

Note that this is not the same as double encryption. But, there will be some cons too. Using this feature will reduce your internet speed as redirection happening twice.

Ok, now we know about VPNs thinking which VPN is best? But before we discuss which VPN you should use. Here are few things you need to consider while choosing a VPN.

What should we look at while choosing a VPN?

The VPN market is crowded with tons of new VPN applications every day. So you need to be aware of the VPN best features which will help you in choosing.

1. Privacy: This is the main concern while looking for a VPN. The VPN should support a Zero-log policy to ensure that your online activities are never tracked.

2. Protocols: The VPN you choose must support most of the protocols that are available like PPTP, OpenVPN along with the latest protocols.

3. No Data Limit: While some of the VPNs will limit your data usage. A true VPN should offer a large bandwidth to download using torrenting or by other means.

4. Server Location: Servers’ location also plays a major role in accessing the content. Since some of the sites are blocked in certain countries, make sure that the VPN will have a huge database.

5. Multiple Devices Access: When you take the VPN subscription you should be able to use the VPN simultaneously on multiple devices.

6. Kill Switch:  If you suddenly drop out of the VPN connection. You should not connect to the internet to keep your identity private. This feature will ensure that.

7. Tor Over VPN: Firstly connecting to a VPN and then using Tor will be referred to as Tor Over VPN. Which yields you the privacy protection of Tor along with the VPN protection prevents Tor node to track IP address.

8. Split Tunneling: If you want to access the local content still insisting on the other countries’ content you don’t need to turn VPN off. Split tunneling will make it done.

9. Cost: This one also should be taken into account as many of the VPNs will cost you much for fewer services while some of them will be upside down to the actual scenario.

Although there are other factors that need to be considered as well if you want to choose the best fit for you. Regardless of the provider, a VPN should also offer security, privacy, and malware detection as well. Now let’s see best VPNs available.

Yes, there are tons of VPNs that are available for free. But they do have their limitations. Here are few limitations of free VPNs:

  • Selling Users Data: Some free VPNs makes money by selling users data to companies and then companies use this data to a target user and sell their product. Which is against the main purpose of VPN i.e, privacy.

  • Speed: There are some VPNs that can’t offer the desired speed you want due to their limitation of server traffic.
  • P2P Services: Not all VPNs will offer you P2P services. So make sure that your VPN will have these features before buying a VPN.
  • Accessing Websites: VPNs might not be able to access some websites like Bank sites. As they will prevent the VPN traffic to prevent frauds. While some good VPNs provide you the privileges to access these sites by whitelisting them.
  • Data Caps: Some of the VPNs will have Data Cap and some platform limitations. So make sure that you won’t have these things on your way while you are choosing.
