VPNs have increased in popularity in recent times, and not without reason. Not only do they provide an additional layer of privacy and security, but also allow you to use the Internet with total freedom.

However, let’s face it – not everyone understands what a VPN can do for them, how it works, and why they should use one. Therefore, this article will attempt to answer all your questions about VPNs in an easy-to-understand manner.

VPN Definition

VPN is the acronym for Virtual Private Networks. It’s a secure, encrypted connection that enables you to access any website or service securely, privately, and anonymously.

What is a VPN tunnel?

When you go online with a VPN, it establishes a connection between your device and the Internet that surrounds your data like a tunnel. Depending on the type of VPN protocol used, the tunnel encapsulates and encrypts data transmitted to and from your device. As a result, nobody can see what you’re up to online – whether it’s your ISP, the government, or advertisers.

Why do you need a VPN?

From secure public Wi-Fi access to enhanced anonymity, there are various benefits you can enjoy by using a VPN. Take a look at these 9 exciting things that you can do with a VPN on your device for a better idea!

What is the difference between VPN and Proxy?

A proxy server serves as an intermediary between your device and the Internet. Since all your traffic is sent through the proxy server, it appears to have originated from its IP address.

With your actual IP address hidden, you can access otherwise unavailable websites and services from your region. However, proxy servers don’t encrypt your traffic, which means cybercriminals can intercept your data.

A VPN, on the other hand, provides all the same benefits of a proxy server but also secures the data you send over the Internet using military-grade encryption. The result? You’re able to browse without the fear of your information getting stolen.

What is the difference between VPN and DNS?

DNS is the acronym for Domain Name System. What it does is translate human-friendly domain names into machine-friendly IP addresses so that browsers can load the website and its content.

By configuring your device to use Google DNS ( and or OpenDNS ( and, you can gain access to websites and services restricted by your ISP’s DNS. But, as with a proxy server, it doesn’t securely tunnel your traffic and leaves it exposed to interference by third-parties.

Moreover, changing your DNS settings doesn’t mask your IP address – not all your traffic is routed via the DNS server! If you want to protect your data and remain anonymous online, you need a VPN because it uses both encryption and IP address masking.

What is the difference between VPN and firewall?

A firewall is essentially a shield or barrier that analyzes network traffic and decides whether to block or allow specific traffic based on a predetermined set of rules.

Firewalls can be either software or hardware in nature and act your first line of defense against threats like worms, malware, and Trojans. It’s important to mention though that they only protect your device from unsolicited incoming traffic.

If you want to safeguard the outgoing traffic of your device, you need a VPN. That said, both of these tools complement each other well and provide optimal security on the Internet when used in conjunction.

VPN app vs. VPN extension vs. VPN browser

As far as VPN extensions and VPN browsers are concerned, they only protect the traffic of your web browser. The remainder of your device’s traffic is still visible to ISPs and potential bad guys, which isn’t ideal from a security standpoint.

A VPN app installed on your mobile or computer will encrypt all the traffic from your device, making it a more complete solution to your data protection woes.
