In an earlier article, we have featured some of the popular proxy services that allow users to browse the web anonymously and to unlock geo-restricted web content from across the world. But proxy services usually have some limitations. They can offer only limited security and access to limited web content (usually text and images). Websites implementing Flash, JavaScript, etc., usually do not render properly over proxy servers. Additionally, proxy servers don’t have global set up options; they have to be configured individually for each program. A Virtual Private Network (VPN) can address these drawbacks of proxy servers. In this article, we’ll explore some of the popular VPN services.

A VPN service allows users to access the Internet by remotely joining them to a private network. Each user is then considered as an individual node in the network. All the traffic within a VPN is encrypted with a minimum of 128-bit AES encryption, so user activity is not visible to the outside world. Thus, users can anonymously send requests to a host server, which can only trace back the requestor’s IP address back to the VPN as a whole, and not to the individual user within the network.

Thus, if users connect to a US or UK based VPN service, they will be able to access US/UK-restricted websites even from countries other than the UK or US. VPN services are required to be configured individually for each device. But once set up, the settings work across all applications, and the entire network traffic is tunneled through the VPN. If traffic is high within the VPN, users may sometimes experience slow connections. These services vary in price, performance, reliability and availability.

Popular VPN services

These are some of the most popular VPN services based on the features they offer:

Private Internet Access

Private Internet Access is one of the most popular VPN services that protect the user’s privacy and security by creating an encrypted tunnel for you to access the web.

It supports Windows, iOS and Android devices and it’s also configurable on routers.

Pros and cons

Here are some of the advantages and disadvantages of using VPN services:


  • User requests are tunneled through the VPN network; hence individual IP address is hidden from the target server, and the user can anonymously browse websites.
  • Once set up on a device, the VPN settings work across all applications.
  • End-to-end encryption (ranging from 128-bit to 2048-bit) protects user activity within the network.
  • Can usually access and unlock a variety of geo-restricted web content.


  • Software-based or manual configuration is required for setting up VPN service.
  • Network speed may be slow when traffic is high depending on the infrastructure of VPN service.
  • End-to-end encryption protects network activity against snooping from the outside, but the VPN service may log user data.

Free v/s Paid VPN services

After going through our list of best VPN services, you might be wondering, why opt for a paid VPN service when free ones are also available. This is because paid services usually invest your money in the maintenance of their infrastructure, which is a key requirement for running a scalable  VPN service. As the number of users increase, these services need to upgrade their hardware so that the servers can withstand the additional load.

If a VPN service is a paid one, it is usually more reliable compared to a free service that may not be able to provide sufficient resources required to handle a growing user base. Due to improper maintenance and unavailability of sufficient funds to upgrade the infrastructure, such a service may be abruptly shut down at any time. So, if you want to use a dedicated VPN or Smart DNS service which is reliable, it is recommended that you go for a paid solution rather than a free one.

Thus, if you are willing to spend money on a service dedicated to let you browse the web anonymously and unlock geo-restricted web content, a paid VPN service is usually more preferable.

But since the entire network traffic is tunneled through VPN, users may experience latency in accessing websites due to several factors like encryption/decryption, high network traffic, etc. If media streaming is your priority and you want to access geo-restricted audio and video streaming services from anywhere in the world, SmartDNS would be more suitable for you.
