Free Vs Paid VPN

In a world of increasing internet activities, the use of VPNs will likely continue to increase over the years. However, a common debate has always been which the better option is between Paid VPNs and Free VPNs. In order to determine which the better option between the two is, we shall conduct a comparison of the various features offered while weighing the advantages and disadvantages of both the Free and Paid VPN. Finally, we will make a recommendation based on which is the best VPN for use.

Here’s what to expect when using a Free VPN

  • Slow speeds and unstable connections
  • Sharing and selling of user information to various 3rd party advertisers
  • Inserts scripts into your PC for online advertising
  • Insecure protocols
  • No active support
  • Most VPNs ban HTTPS browsing

The following are features you will receive when using Paid VPNs

  • Premium Customer care and services
  • More (unlimited) Bandwidth
  • Multi-device use
  • High level and reliable encryption
  • Fast and stable connections
  • Multiple Servers evenly spread out

The following are important details that must be considered when choosing between Paid and Free VPN services


Free VPNs: do not rely on their servers to sustain their services; instead, they sell user bandwidth while collecting data logs. Unfortunately, Free VPNs rely on your computer activities to serve the bandwidth of other users. This consequently slows down your PC as your processors and bandwidth are used as servers for other clients

Paid VPNS: Premium VPNs have servers spread out across different countries. The presence of servers ensures that connections can be maintained at all times without compromising privacy or affecting speed of your PC

Verdict: When it comes to servers, Paid VPNs win due to their reliability in connection


Free VPNs: Cheap can turn out to expensive when using free VPNS. This is due to the lack of a reliable support team to guide the user through various steps. Additionally, the lack of support exposes users to the risk of sharing personal information or being attacked by malicious web users when attempting to navigate through the system

Paid VPNs: Paid VPNs usually offer 24/7 support with call support for selected regions. Therefore, you can learn anything or ask any question while seeking clarifications on the use of the VPN from the ever responsive support. Additionally, the support makes using the VPN easier as they promptly respond to user issues or queries.

Verdict: Support is essential when dealing with VPNs as they make usage easier and smoother. Paid VPNS win due to 24/7 responsive support

VPN Protocols

Free VPNS: Free VPN services often provide PPTP VPNS only. Unfortunately, PPTP VPN is insecure and exposes you to the risk of online attacks or stolen identity by malicious users and hackers. Using such VPNs at the airports or public places does not protect you from hackers as they can access your login details and user information

Paid VPNs: Users of paid VPNs can use PPTP, Open VPN, L2TP/IPSEC, SSH, and even SSTP to secure all connections. This means that connections are secure from hackers and malicious internet users. Paid VPN therefore, appears more reliable when it comes to privacy and security as all the protocols make it possible for users to browse from anywhere without fearing security breaches.

Verdict: Paid VPNs win when it comes to VPN Protocols

Connection Speed

Free VPNs: Users of free VPNs are mostly affected by reduced speed levels. This is due to the lack of servers and also the congested number of users limiting overall bandwidth. Thus, speed levels are usually dependent on the number of users online.

Paid VPNs: As mentioned earlier, paid VPNs rely on servers to offer bandwidth and secure connections to users. This means your processor and bandwidth is only reserved for personal PC use based on your subscription. Therefore, paid VPNs are consistent and reliable when it comes to speed due to the even distribution of servers across different countries

Verdict: Paid VPNs win due to their consistency in connection speed


Free VPNs: Free VPNs require little to no personal information when signing in. This is because no payment details are required. Further, the lack of customer support means that no contact details will be exchanged when using a free VPN. Therefore, free VPNs are effective when in need of light browsing or short access to blocked sites

Paid VPN: Personal details such as credit card number or a PayPal email address may be required due to payments. Thus, you will have to share some personal information and contact details when signing up for Paid VPN services. However, Paid VPNs secure the information provided and do not release them to third parties

Verdict: Free VPNs win due to the ease of signing up but paid VPNs also secure your login information and do not share with anyone and if you think not to share even payment details then you can get paid VPNs with bitcoin where you only have to do with email address.


Free VPNs: Free VPNs are often characterized by unending user ads which might end up compromising the use. Additionally, the connection can be interrupted due to server congestions which might disrupt usage. User activities is usually monitored by bots which might lead to illegal access of user accounts and bank information

Paid VPNs: Most paid VPNs use state of the art technology that clears all user logs in a bid to secure user connections. This prevents bots from recognizing your browsing preferences and lining up relevant ads. Therefore, Paid VPNs are secure as they do not store any user information. Also, the secure and stable connection helps ensure the user remains connected and protected at all times

Final Verdict

Although Free VPNs might appear cheap and easy to access, they do come at a costly price. Free VPNs are less secure and stable which reduce their usability. Also, the lack of a 24/7 support makes it harder to navigate the sites thus limiting the scope of use. However, paid VPNS are more stable and reliable as they have servers evenly distributed across multiple countries. This makes the connection stable, and the use of multiple protocols such as Open VPN, L2TP/IPSEC, SSH make it safer for use. Paid VPNs do not monitor user activities; this makes them safer and more reliable when dealing with important and personal issues. Therefore, when compared to free VPNs, paid VPNs are more effective, reliable and secure as they offer value for money and protect you every time you are online.

VPN for Beginners – Virtual Private Networks Complete Guide

A VPN is the most commonly used tool by internet users worldwide for securing their online activities. A VPN basically means a "tunnel" that connects the internet user securely and anonymously with a website or a public network such as a Wi-Fi.

The rising instances of government tracking and hacking activities have made the VPN an ideal tool for warding off such threats. This tool has made it easier for frequent internet users to work online without any fear of unwanted tracking. A VPN is a paid service offered by numerous VPN service providers for a fee based on the duration the user opts for.

How is a commercial VPN different from a corporate VPN?

The first VPN was formulated solely for the use of business organizations to ensure confidentiality of their data. These VPNs are termed as "corporate VPNs".

On the contrary, a commercial VPN is meant for the use of ordinary users for their private usage. This guide mainly focusses on the commercial virtual private networks, while most of the providers offer both types of VPN services.

Types of VPN

Basically, there are two types of virtual private networks - the remote access VPN and Site-to-Site VPN. The former type helps the users to remotely connect to a LAN device and access their private servers or databases securely, while the latter helps the users to connect securely to a public network or website.

There are different types of VPN protocols which have their own level of encryption. The PPTP is the most commonly used protocol which requires the users to access the VPN server only after authentication via username and password.

How Does A VPN Work?

To understand how a VPN works, it is important for users to know about the various types of VPN protocols used in for encrypting data transmitted to the VPN servers.

i) PPTP:

Refers to the point-to-point transfer protocol that helps the user to securely connect to a private server from a remote location.z

ii) L2TP:

Layering-2-Tunneling Protocol is similar to PPTP and helps users to securely connect to two websites

iii) IPSec:

IP security helps to establish a secure connection between two networks or an individual device with these networks.

iv) SSL:

Secure Sockets Layer is a three-way system to ensure safety by using digital certificates for the websites.

VPN Process

VPN Process

The users are first connected to their internet service provider (ISP) which provides them the access to the websites they wish to visit or surf.

The user activity is encrypted and monitored by the ISP who can see the data being transmitted to the websites.

The VPN process starts with the user's network being connected to an encrypted server that is hidden to the ISP.

A VPN protocol is associated with the server connection to provide varying levels of encryption for the user.

The end result is a completely secure and anonymous connection for the user on a virtually created private network.

Setting up a VPN

Following is a short checklist for the users wanting to set up a VPN on their handset/desktop PC.

  • Users must check the type of device, operation system (OS), and its version. This is important to make sure whether the VPN is compatible on their device or not.
  • There are different versions of VPN applications for routers, smartphones, tablets and desktops. For example, Windows 10 OS and Macintosh OS X have different VPN software. Similarly, iOS and Android have different VPN apps for users.
  • Users need to download and install the compatible VPN software on their devices from the official website of the VPN service provider. Android/iOS users can download the VPN apps from their respective app stores. Often, there are free trials offered before users can make their purchase.
  • Next, the users need to purchase the subscription of their choice from the VPN provider for the duration specified. Most commonly offered packages by VPN companies are annual and monthly subscriptions.
  • Finally, users need to log in to their VPN accounts by entering the Username & Password obtained at the time of purchase. Post login, the users can easily connect to the available VPN servers across the globe.

Phases of a VPN Connection

There are three important phases for establishing a VPN connection successfully:

a) Authentication

Users need to verify their identity before they can access the VPN server. They need to provide the login credentials like Username and Password in order to use the server. The device sends a request to the VPN server to initiate authentication of the user.

b) Secure Tunnel Creation

Post authentication, the user can connect to the available VPN server by selecting the server country/location.

Once the VPN connection is established, a virtual "tunnel" is created through which the data can be transmitted securely and anonymously.

c) Encryption

Finally, the user data is encrypted to prevent any tracking or hacking activities. The tunnel is used to transmit the coded data between the websites. Free VPN providers do not provide this privilege. The IP address of the user can be changed or hidden to prevent ISP to monitor their online activities.

Results of Using a VPN

Following are the implications the users should know before utilizing a VPN software.

1. The users' Internet Service Providers (ISP) would not be able to track or monitor any data or websites. VPN servers use high-end encryption technologies to ensure maximum user privacy.

2. The Internet Protocol Address (IP) is changed temporarily while using VPN. The user's IP address is set by the VPN server of the selected country/location, thus hiding the real IP address of the user.

3. The VPN provider can track the user data and websites visited by the user. Privacy is guaranteed by most of the VPN providers through their "no log" policies.

4. It is possible for the internet speed to reduce due to the power required by the servers to encrypt or decrypt data.

Legality of Use

Using virtual private networks is completely legal in most of the countries around the world. Such countries usually do not impose restrictions on internet access for its citizens.

But there a few countries which do not encourage unrestricted usage of internet due to security reasons.

Some of the countries which have banned the usage of VPN include China, Iran, France and Saudi Arabia. Despite the government restrictions, some of the VPN servers do operate in these countries without any legal trouble.

What is a VPN?

VPN: A Brief Overview

Virtual Private Network (VPN) is a widely used technology for enhancing the user's internet accessibility and security. The history of VPN dates back to the year 1996 when an employee of Microsoft formulated the P2P protocol which was succeeded by the modern virtual private network (VPN).

VPN is significantly different from a traditional private network. A VPN uses an internet service provider (ISP) as the mediator between the user and the public internet system unlike a private network uses a system of leased lines. Basically, a VPN is a private network connection created virtually over the internet.

Now, the question arises, is the use of VPN legal? Usage of virtual private networks is not considered to be a violation of law in most of the countries and big companies are already relying on VPNs to conduct efficient business with confidentiality. There are some countries like Saudi Arabia, France and China which do not allow the use of VPN technology for security reasons.

What Is a VPN?

1. VPN Meaning & Types of VPN

What is VPN Stand For?

A virtual private network (VPN) is a technology that is used to create a secure "tunnel" over the internet. The "tunnel" refers to a highly encrypted and private network that ensures anonymity of the user while working on a relatively unsafe public network.

VPNs are supported on a wide range of devices and operating platforms which include computers, desktops, mobiles, tablets, WiFi routers, etc. running on Windows, Mac, Android, iOS and many more.

The users are connected through a P2P (point-to-point) system in a VPN which enables them to obtain a different IP address. This helps them to transmit data at faster speeds without having their original identities revealed.

The connections are made secure through VPN protocols which help the user data to be encrypted. The level of encryption depends to the type of VPN protocol used to secure the VPN network.

Most VPN providers have a global network distribution to enable the users to access these networks from their place of work or residence. This helps them to access websites that are restricted due to geographic location or government actions.

VPNs are of three basic types namely: WAN (Wide Area Network) is often used for connecting branch offices of a company, Access VPN is used for users who are travelling and need access to location-restricted websites. Finally, the Extranet VPN is used for customer-supplier networks.

2. Types of VPN Protocols

What is VPN Protocols?

The users often use the VPN networks to secure their sensitive data from being misused on a public internet network. Businesses can connect securely to their different branch locations easily with VPNs. The level of security/encryption provided depends on the type of VPN protocol associated with the connection.

Here are the basic types of VPN protocols which are commonly used:

a) IPsec (IP Security):

What is IPSec VPN?

This protocol refers to the Internet Protocol Security and is the mostly commonly used encryption method in a VPN. It helps to establish a secure connection between two networks or an individual device with these networks. This protocol is used as a layer of security for other types of encryption protocols too.

b) P2P Protocol:

What is VPN P2P?

This refers to the Point-to-Point protocol which uses the "tunneling" technique to establish an encrypted connection between a remote client server and a private server. This helps the users to share and transmit data securely to a dedicated private server.

c) L2TP:

What is VPN L2TP?

It is another type of VPN encryption which refers to the Layering to Tunneling Protocol. It is a combined encryption of Cisco's L2F and Microsoft's PPTP algorithms used to establish a secure connection between two websites.

d) SSL:

What is SSL VPN?

Secure Sockets Layer refer to the VPN protocol which uses digital certificates in order to authenticate servers for their safe and security. The coded information is stored as a security certificate to define the website as "safe" and "secure".

3. Basic Components of a VPN

i) IP-Address

The internet protocol address acts as the identification component of a VPN network. The IP Address refers to a 32 bit number which identifies the sender and receiver of data on the network. It is a 32 bit system, hence is popularly referred to as IPv4 (version 4).

The newer version is IPv6 which offers a greater number of addresses than the IPv4 and is expected to be supported by the VPN providers soon.

The role of VPN is to provide a different IP address to the users in order to avoid unwanted tracking from the internet traffic which include government agencies. The changing IP addresses allows the users to hide their actual location, making it possible to access geographically restricted websites while on a VPN server.

ii) IP-Packet

The IP-Packet is simply the load on the VPN server. It is the specified set of data transmitted over the server by the user while uploading, downloading or streaming data over the network. Technically, the IP-Packet is defined as a "payload" on the VPN server.

The IP-Packet consists of a set of communication rules which include the "address headers" and other identification indicators. There are specific limits to the amount of data transmitted by the user depending on the packet length used.

The packet length limits for a standard IPv4 protocol is by default: 20 bytes minimum and 65,535 bytes maximum. So for IPv4, the maximum transmission limit is 65,535 bytes on that particular IP address.

Security Mechanisms

Virtual private networks offer a wide range of security and privacy options to the users with the help of various encryption techniques. Most of the VPN servers have a 256-bit encryption for the user's safety and privacy. This may vary from the different IP protocols associated with the server.

What is VPN encryption?

Encryption refers to the coding of the simple text or characters that are readable into a unique ciphertext. This code can only be read by the authorized user computer. This helps to protect the user data from being exposed to the internet traffic, thus preventing risk of data theft.

There are encryption protocols implemented with the help of different methods explained below:

Encapsulation Mode: This method of encryption is associated with the IPSec protocol described above. It helps to establish a secure connection between two networks through "tunneling". A tunnel helps to encrypt the data securely in the server's IP-address, which is "encapsulated". This method enables the users to hide their actual IP addresses to avoid tracking.

Transport Mode: This method is a shorter version of the encapsulation mode. The difference is that the IP address of the target website remains the same. Only the user data is encrypted on the VPN server.

Future Scope of VPN

With advancing technology, the risks and threats to cybersecurity will increase. Virtual private networks (VPN) are expected to be in high demand in the near future.

Businesses would be greatly benefited from an evolution and upgradation of the VPN technology. It would make it much easier to transact securely over the internet.

VPN would be the best technology that would promote free flow of data and information over the internet irrespective of the user's geographic location.

The launch of the IPv6 protocol in the VPN industry would be a great boost to its performance and user satisfaction.
