Decoding VPNs: Functionality, risks and best choices (2024)

In an era dominated by digital connectivity, concerns about online privacy and security have become more pronounced than ever. Virtual Private Networks (VPNs) have emerged as powerful tools to address these concerns, offering users a secure and private online experience. This article delves into the world of VPNs, exploring their functionality, the best VPN providers, the allure of free VPNs and the crucial question – do VPNs really work?

What do VPNs do?

Decoding VPNs: Functionality, risks and best choices (1)

A Virtual Private Network (VPN) is essentially a secure tunnel that encrypts your internet connection, providing a layer of privacy and security. Here's a closer look at what VPNs do:

1. Encryption and privacy

VPNs encrypt your internet traffic, making it nearly impossible for anyone to intercept and decipher your data. This is particularly crucial when accessing public Wi-Fi networks, where cyber threats abound.

2. Masking IP address

By routing your connection through servers in different locations, VPNs mask your IP address. This not only enhances privacy but also allows you to access content that might be restricted in your region.

3. Bypassing geo-restrictions

VPNs enable users to bypass restrictions imposed by certain websites or streaming services based on geography. When a nation or state has specific laws that limit content you can see on the internet, a VPN connects you to servers in a region where that content is accessible.

The effectiveness of VPNs is a common question among users. Let's delve into the key aspects that contribute to the functionality of VPNs:

1. Security protocols

The security of a VPN largely depends on the protocols it employs. Leading VPN providers utilize robust protocols like OpenVPN, IKEv2/IPsec and L2TP/IPsec, ensuring a secure connection. It's crucial to choose a VPN with up-to-date security protocols.

2. Server locations

The number and distribution of servers play a significant role in a VPN's functionality. More servers, strategically located around the globe, mean better performance and the ability to bypass geo-restrictions effectively.

3. No-logs policy

A trustworthy VPN provider adheres to a strict no-logs policy, meaning they don't record your online activities. This ensures that even if someone were to request your data, there would be nothing to share.

4. DNS leak protection

A DNS server, also known as a Domain Name System server, functions as a computer tasked with translating domain names into corresponding IP addresses. This process is referred to as DNS resolution. The significance of DNS leaks lies in their potential to compromise user privacy by exposing browsing activities. Fortinet highlights that a DNS leak is a security vulnerability wherein requests are inadvertently directed to an Internet Service Provider's (ISP) DNS servers, even when a VPN is actively safeguarding users. VPNs are crafted to encrypt a user's internet connection, establishing a private tunnel that conceals all online activities. This shields internet searches and website visits from external scrutiny, with the exception of the VPN provider. A dependable VPN incorporates DNS leak protection mechanisms to avert such vulnerabilities.
