How VPN Services Protect Your Data

Written by  Sep 23, 2019

Wherever you are, a virtual private network is still one of the best ways to secure your data on the internet. However, what is the best VPN for you? How effective would it be? What are the disadvantages?

The intent of VPNs is to give privacy and security to people as they browse the internet. But the dilemma with the internet is it is essentially insecure. When it was first created, the purpose was to send chunks of data as consistently as possible. Nearly all of the core protocols of the internet were designed to direct along with failure, instead of securing data.

These protocols leave internet users susceptible to hackers who may procure their credit card or banking info, governments who want to spy on their people, and other individuals who want to track your activities for their gain and probably your loss. A virtual private network builds a private tunnel throughout the internet. The notion is that every piece of info you send is compressed in this channel and encrypted.Thus, they cannot be deciphered. For a little help, here’s a guide on how VPNs protect your data on the internet.

How Do VPN's Work?

Imagine you want to go to a particular website. Your computer or mobile device starts a request by dispatching chunks of data. These chunks of data usually traverse through routers and switches on your local area network (LAN) before they’re transmitted to the public internet via a router.

As soon as the packets are transferred to the public internet, these chunks of data pass through multiple computers. An individual request is then created to a series of servers to render the domain name system (DNS) name of the website to an IP address.

That info is forwarded back to your internet browser, which sends the request, once more,through multiple devices on the public internet. Ultimately, it reaches the infrastructure of the particular website, which directs those chunks of data as well, then obtains a webpage, and dispatches all of that back to you or the user.

Every internet request typically produces a series of transmission between a bunch of points. VPNs work by encrypting data or information at the starting point, usually concealing not only the data but the info about your starting IP address.

The virtual private network software on your part then dispatches those chunks of data to your VPN server at some boarding point, unraveling that information.


When Do You Use Your VPN Connection?

Wherever you are, as long as you are using the internet, always use a VPN. If you are away from home, you often connect to the public internet. Often times, the connection requires a password. Sometimes, it’ll be entirely open. In both cases, you don’t know who else is using the same internet network, and thus, you won’t know who may be spying on your web traffic.

With that said, it’s best to always use a virtual private network, especially when you are connecting to someone else’s internet. It is inherently critical if you are using a service that involves personally-identifying information.

Keep in mind that many things happen behind your back, and you never know if your applications are validating in the background and jeopardising your information. Moreover, another rationale to use a virtual private network is if you have some sensitive information to hide.

How To Choose a VPN Service?

For the most part, not all paid VPN services are real and legit. Thus, it is essential to be wary of who you select. Also, some services are better than other services. Personally I use Norton Secure VPN and I would steer clear of the free ones as they are not all trustworthy and I would not feel comfortable trusting my private connection with just anybody.

If you notice many complaints, whether old or new, it may be that there has been an update of policies or management. It is always a great practice to base your decision on professional reviews as well as the tone of the reviewers. Lastly, make sure to select a VPN service that meets your needs. Therefore, consider your needs before making a decision.

Can VPNs Assure Your Privacy?

A VPN cannot guarantee your privacy. Its purpose is to ensure you are not spied on when accessing a website on your device. However, the website itself can have some privacy violations. For instance, VPNs cannot safeguard you from a website that has a tracking cookie that’ll tell other sites about you.

A virtual private network cannot protect you from a site tracking information or data about the products you are fascinated in. It cannot protect you from a website giving your email address to brokers. And many more.

However, VPNs do aid you in protecting your data and hiding your physical location. Still, do not expect VPNs to be privacy shields that’ll keep all your activities confidential and private. There are a lot of ways your privacy can be, for the most part, compromised, and VPNs will help partially.


What does a virtual private network do to safeguard your data on the internet? Well, it protects your data against data stealers, hackers, and alike. It encrypts your whole web session, bandwidth compress, lets you access anything on the internet, and hides your address. In this day and age I would not browse the internet without the assurance of a VPN.
