We can say that personal online privacy is under siege from many directions. Today, we don't just have to worry about cybercriminals and organizations that want to steal our data for some reason.

Hence, adopting a VPN should be the next step every Internet user should commit to. This issue will address frustrations and concerns about the threats posed by users online. Finally, you understand the true nature and outstanding features of a VPN. If you're still wondering which VPN to choose, here are our recommendations:

  • ExpressVPN - Best for Beginners

I. What is VPN?

VPN (Virtual Private Network) allows users to establish a virtual private network with another network on the Internet. Basically, each VPN is a separate network using a shared network called the Internet to connect between two or more networks or remote users. Instead of using authentic and specialized connections such as leased-line, each VPN uses the virtual connection linked over the Internet from a separate network of companies to remote sites and staff. 

VPN is sometimes misunderstood as the alternative option to access the Internet, which is not appropriate.

VPNs were first created to connect to business networks for more secure and convenient communication. Nowadays, VPN service providers are working hard to transit all your traffic to the Internet, bypassing the government or ISP’s observation and evenly being affirmed in some cases. 

In short, it would be best to consider VPN as a type of service that is designed to help you get full access to the Internet and protect yourself while performing it.

II. VPN’s classification

1. Two Basic Types of VPN

1.1 Remote Access VPN

Using Remote Access VPN, users can connect to a private network and remotely access its services and resources. 

Besides, Remote Access VPN is suitable for business users as well as households. For instance, a staff member can use VPN to connect to his or her company’s private network and get access to the files and resources on the private network remotely. Household or individual users mainly use VPN to overcome the regional restrictions on the Internet and access blocked websites. Internet security-conscious users also use VPN services to enhance their protection and privacy on the Internet.

1.2 Site-To-Site VPN

Site-to-Site VPN is also known as Router - to - Router VPN and mainly used in enterprises. Many companies that have their representative offices located in different places use Site-to-Site VPN to connect to the network from one office to another. Site-to-Site VPN is divided into different kinds based on the office locations of the companies. Specifically, it is called Intranet-based VPN when many offices of the same company are connected by using a Site-to-Site VPN type.  If companies use a Site-to-Site VPN type to connect to other company's offices, it is called Extranet-based VPN. 

Fundamentally, Size - to - Size VPN creates a virtual link between networks in geographically distant offices and connects them via the Internet, helping maintain secure and private communication between networks.

As Site - to - Size VPN bases on Router - to - Router communication, one router acts as Since Site - to - Site VPN is based on the Router - to - Router communication, one router acts as a VPN client and another as the VPN Server. Communication between the two routers only begins after the successful authentication of the routers.

2. Types of VPN Protocols

The two types of VPNs above rely on different VPN security protocols. Each VPN protocol offers different features and levels of security, which are explained as follows:

2.1 Layer 2 Tunneling Protocol (L2TP)

L2TP is a tunneling protocol combined with another VPN security protocol like IPSec to create a more secure VPN connection. L2TP creates tunneling between the two connection points L2TP and IPSec, helping to encode data and handle secure communication between tunneling.

2.2 Openvpn

OpenVPN is an open-source VPN that is useful for creating Point - to - Point and Site-to-Site connections. It makes use of a custom security protocol based on SSL and TLS.

2.3 Secure Socket Tunneling Protocol (SSTP)

Although SSTP is a less known one among ordinary people, it is helpful because it has been thoroughly tested and assembled in every Windows version since Vista SP1.

Furthermore, it is also very secure by using SSL 256-bit lock and SSL/TLS 2048-bit certificates. SSTP has both an upside and downside when it is exclusive to Microsoft and not open to the public.

2.4 Internet Key Exchange version 2 (IKEv2)

IKEv2, which Microsoft and Cisco jointly developed, was initially intended as simply a tunneling protocol. Hence, it also uses IPSec for encryption. Its agility to reconnect to lost connections has made it very popular among those who utilize it to deploy VPNs on mobile devices.

2.5 Point-to-Point Tunneling Protocol (PPTP)

PPTP is one of the giants among the oldest VPN protocols. Although there are still some use cases, this protocol has been reduced mainly by the parties due to significant, apparent gaps in its security. It only saves the grace of its speed. As I mentioned before, the more secure the connection is, the more likely the speed is to decrease.

III. What is a VPN used for, and how to use it?

1. What VPN offers users?

1.1 To play area blocked games from anywhere

Have you ever desired to play an online game but found out it is blocked in Vietnam? You are not alone because this problem is common to gamers around the world. However, with a VPN, you can adjust your location and play any games you love from anywhere globally. 

1.2 To get better privacy and anonymity

Have you ever sent your banking information to friends online? How often do you use public Wi-Fi networks? If so, you might have given hackers the chance to hack into, especially if you are using the public Wi-Fi hotspot.

A good VPN utilizes the most advanced encryption to secure your data. It also makes sure that your data processing websites cannot know where it comes from, helping to keep you (almost) completely anonymous online.

1.3 To bypass the censorship

It would be best for numerous countries over the world to censor the content. The reason is that it is not appropriate with their political or religious beliefs. If you plan to have a holiday in a country with heavy Internet censorship, China, for example, you'll need a VPN to help you get around the restrictions. But for VPN, you cannot perform simple tasks such as Google Search or Facebook status update. Thus, a VPN helps you to unblock these websites and keep your data safe from prying eyes at the same time.

Also, you can make use of a VPN to bypass the standard firewalls found on office or school networks.

1.4 To improve your Internet speed and access 

Sometimes, your ISP can deliberately slow down your Internet connection. The reason can be that they find out that you're torrenting or exceeding a specific data limit. Several ISP evenly uses this strategy to make you upgrade your connection, which is known as "squeeze bandwidth.”

Nevertheless, your activities are still kept private with the help of a VPN, and even your ISP also cannot see them. It means that they cannot squeeze your bandwidth so that you can see the speed increase.

1.5 To save money

Occasionally, a VPN is capable of helping you to save your budget. So how? Many e-commerce platforms show different price tags to users based on their locations. Thus, connecting to a server in a different country may offer you cheaper rates. For instance, if booking a flight from the US to the UK seems too expensive, you might find cheaper fares by connecting to a server in India. 

2. Which type of VPN is suitable for you?

So how can you choose the best VPN? That depends on what do you use VPN for. Let’s take a look at the below situations and consider which is the most suitable for your need. Here we will share some tips to find out the most appropriate VPN for you, based on the following points:

  • Super-secure encryption: Your VPN should have the most secure, military-grade 256-bit AES encryption in the field. It will protect your information from hackers.

  • Security protocols: Make sure that the VPN includes the OpenVPN or IKEv2 protocols. These are the most potent available protocols and will ensure that your data is kept private at all times.

  • DNS leak protection: Occasionally, software problems can result in your IP address being seen even when using a VPN. That's not what you want as you're on a public network. So how can you solve it? Well, some VPNs, ExpressVPN, for instance, have built-in protection that helps prevent this from happening.

  • Disconnect feature: This feature disconnects you from the Internet if the VPN connection fails. This is important because it ensures that your data is never exposed to others on the same network. Not all VPNs will have disconnections, so make sure you choose a VPN that has this feature.

IV. What is the way to set up using a VPN?

V. Frequently Asked Questions (FAQs)

1. Can my VPN service be locked?

Some countries are stringent Internet censorship and even made to block VPN services. Although they cannot decrypt the data, blocking VPNs in those countries means blocking VPN access successfully by stopping access to ports which popular VPN protocols commonly use. 

For example, China's Great Firewall is a small part of the country's ways to maintain public security by closely monitoring information systems.

2. How can I know whether my VPN is secured well or not?

VPN services, of course, rely on selling their privacy and security. So how do you know if the service you've chosen is working as advertised? Is your IP secure? What about leaks you've heard about? These concerns are sometimes the things I call a 'broken feature' by some VPN providers. That means they aren't performing as advertised, and your identity is at risk.

4. Does VPN slow down my Internet connection?

The answer is Yes. Because of the nature of this service, the network connection will be a bit slower. However, with most reputable VPN services, the network connection is not noticeably slow. 

Nevertheless, if your ISP adjusts your Internet speed for some reason, then using a VPN might improve it. Many of the top VPN providers have networks that are suitable for level 1 bandwidth providers. As a general rule, the farther server you choose to connect to, the slower your connection will be.

5. Can I use a VPN on multiple devices?

Most VPN providers have apps that are specific to certain types of operating systems and devices. If you want to operate your VPN across multiple devices, make sure the provider you choose allows simultaneous connections and has apps for all your favorite devices.

6. Can I pay for my VPN service if I do not have a credit card?

Credit cards make our digital lives easy because they are successful means of making payments for suppliers. Yet, when it comes to VPN services, it seems a bit strange to pay an anonymous person in a way that has to identify yourself.

 Fortunately, several service providers have started accepting payments in Bitcoin or other cryptocurrencies. To see if the service provider you use accepts Bitcoin, check the Bitcoin symbol on the accepted payment methods page on the VPN website.

Of course, if you choose to pay with Bitcoin, there will be no automatic renewal, and you will have to make payments each time the service renews.
