Importance of VPN – Online Security and Privacy




Ever wondered why you see ads relevant to your browsing history? When you search for a product on Amazon even without logging in, you see an Amazon ad wherever you go afterward. This is a very usual experience for every internet user these days, but this should be alerting for you. This can be negative for your online identity if you are a user who does browsing on different networks and do a search on different miscellaneous content online (torrents to the dark web).

Data tracking is a major threat these days, showing ads via data tracking is the most common example and yet people are unaware that they can be tracked and their whole system can be hacked by a mistake of few clicks. This blog is for those who do really care about their online tracks and do understand the potential threats of insecure browsing.

In this blog, we are going to clear the three recurring questions regarding Virtual Private Network and going to clear you out the importance of VPN and online security. So let’s get right into it…


Not going with the generic definition (like an encyclopedia or other), a VPN is something that can be used as a mask for you to hide your face from potential threats. A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. Trackers/hackers trace you with your system’s IP address, VPN helps you to cover and encrypt your IP to create a virtually untraceable network, basically a private network of your own.

A VPN can hide a lot of information that can put your privacy at risk. Like your browsing history, your IP address and location, your device, and your location for streaming. These are the most common abilities of VPN to create online security but in actual, the ability factors are far more than to be written in a single blog.


Moving to the confusing “WHY”, the straight forward answer to this is; if you do browse miscellaneous content (like torrents and dark web) and you use different networks very often, then you should go for it.

If you use public Wi-Fi or any other open hotspots that are free for public use, then you’re openly exposing your IP and other traceable data like your location, your device, your browsing data, etc. Surfing the web or transacting on an unsecured Wi-Fi network can be a threat to your private information and browsing habits. That’s why a virtual private network, better known as a VPN, should be a must for anyone concerned about their online security and privacy.

VPNs use encryption to scramble data when it’s sent over a Wi-Fi network. Encryption makes the data unreadable. Data security is especially important when using a public Wi-Fi network because it prevents anyone else on the network from eavesdropping on your internet activity. Though Wi-Fi is not the only threat to your security, your own network can be troubleful if you browse for the content that is not secure and illegal in some countries. Most people don’t use VPNs while downloading torrents and surfing the dark web and get caught up hacking situations and more often lose their device and data on the mistake of a few clicks.

VPNs keep your web browsing anonymous, the encryption and anonymity that a VPN provides help protect your online activities: sending emails, shopping online, or paying bills. If you care about all these, then there should be no more “why?” against the importance of VPN on your daily use.

WHEN should I use VPN?

So many “when” situation is already mentioned above, but still we’re mentioning the quite possibilities when you should VPN for sure, so here’s the list:

  • When you’re on public Wi-Fi
  • When you’re traveling
  • When you’re a remote worker or student
  • When you browse for any kind of miscellaneous content
  • When you just want some privacy

So if you do understand the importance of online privacy then may have understood the importance of VPN by now.

At last, a word of caution about VPNs:

With a VPN, indeed, your ISP may no longer have access to your browsing data, but the VPN provider now does. Some VPNs even sell that data to third parties, so in that way, you could be right back where you started. That’s why you should be especially cautious of “free” VPNs. Those services still have to make money, and chances are your data is the primary revenue source. That said, the VPN’s terms may be more favorable to your privacy than, say, Comcast’s. However, if you want to play things safer, you’re better off paying for a VPN.
