In today's world, the security and privacy of data that travels through the cyberspace have become an essential concern for the individual users and the organizations. Apart from this, the government of many countries has also imposed many censorship rules on the way their citizens should use the Internet. All this has resulted in VPNs (Virtual Private Network) becoming very popular as it allows the users and organizations to secure and circumvent their Internet connection to a great extent. In this paper, we mainly study three types of most common VPNs and present a comparative study of their features, performance, security and a few other aspects. We hope that our research will offer a clear understanding of the users and will help them make their decision on choosing the correct VPN based on their need and priority regarding security, speed, and cost.
