Are VPNs worth it?

It stands for “virtual private network.”  But what is that exactly—and is it safe?


It puts your system in lock down

Here’s what happens whenever you access a website without using a VPN:

You first connect to your internet service provider (ISP), and they redirect you to the website you’ve chosen. Everything you do online passes through your ISP’s servers, so they know all about you. They can also log everything you do—and hand this over to third parties like advertisers or even government agencies. 


And here is what happens when you use VPN:

Your internet traffic is redirected through a remote server, which hides your IP address (your device’s unique identifier) and encrypts all your internet traffic. VPN is essentially a secure, private tunnel through which all your communications run. 


No one can get their hands on your private information, and thanks to high-level encryption, they can’t read it even if they do find it! With a VPN, you’re an online phantom. You’re invisible, so none of your activities can be traced back to you, your device, or your location. That’s bad news for hackers, advertisers, and snoops, but great for your online safety and privacy. 

Online risks you avoid

The internet is full of scams, and in particular, using public WiFi without a VPN makes you vulnerable. Here are 4 popular methods used to gain access to your data, including passwords and banking details.


Man-in-the-Middle (MITM) attacks occur when a malicious third party intercepts your communication.


Using packet sniffing software, hackers can intercept and log data traveling over a free WiFi network. These streams of data, or packets, can be downloaded and saved.


Session hijacking exploits a vulnerability with cookies, which are small data files saved by your browser on your device. By hijacking your browser session over a public WiFi network, hackers can easily capture this data and log in to a website as you.

Malicious hotspots are quick to be set up and can look like legitimate WiFi networks. They can easily trick you into logging in and, with your device connected to their networks, hackers can steal your personal information.

Should I use a VPN?

If you’re serious about your security and privacy, then, yes! Even if you have nothing to hide, do you like the idea of being watched and tracked?

A VPN is for everyone, but most strongly recommended if:

You regularly use public WiFi

These are not secure, and hackers use many methods to intercept your internet traffic. They can then steal your passwords and other confidential data, access your private photos, and even steal your identity.

You use file sharing services

Many ISPs try to limit file sharing services, like P2P (Peer-to-Peer). They restrict your choices and might even slow down your internet speed. Using a VPN makes it difficult for an ISP to detect your file downloads and uploads.

You’re a journalist or anyone who shares sensitive info

If you’re in a line of work that involves sending sensitive information, then protecting your data, identity, and information sources is essential.

What are the other advantages of a VPN?

It does so much more than hiding or changing your IP address.


Safely use public WiFi

Public WiFi (in restaurants, cafes, etc.) is unsafe as others in this network can access your data. Surfing with an active VPN connection encrypts all data received and sent, so you’re safe from hackers.

Unblock websites

By hiding your IP address, you can bypass regional censorship. So, if you’re abroad, choose a VPN server from home to watch your favorite show and beat geo-blocking! And gamers can play with the world!

Evade tracking

Advertisers track your IP address to send you targeted ads. Not with Phantom VPN! It assigns you a different IP addresses with every connection, and none of them can be traced back to you.
