How do VPNs Actually Work?

Back to the beginning. A virtual Private Network is a VPN. Your online safety, privacy, and freedom may all be increased quickly and easily by using a VPN.

Your device is constantly sharing data with other parties on the internet when you are using the internet. A VPN builds a safe connection between your computer, smartphone, or other device and the internet. The VPN enables you to communicate data to the VPN server, an external server, over a secure, encrypted connection. Your data will then be transmitted further to reach its online destination.

There are various benefits to redirecting your internet traffic through a VPN server. It first aids with online identity concealment. It also protects your info. Thirdly, it gives you more freedom to utilize the internet.

What a VPN Does

In order for your data to be transmitted to the internet from the VPN and not your computer, a VPN works by redirecting your device’s internet connection through the private server of your preferred VPN rather than your ISP.

Your ISP assigns your device an IP address, which is a string of numbers, and the VPN functions as a type of middleman as you connect to the internet, masking your IP address and safeguarding your identity. Additionally, until it reaches its intended location, your data will be unintelligible if it is somehow intercepted.

A VPN uses encryption to build a secure “tunnel” between your device to the internet and conceal your sensitive information.

The Basics Of VPN Encryption

When utilizing a VPN, your data is kept private using a process known as encryption.

With encryption, data is concealed in such a way that it can’t be read without an extremely strong password, often referred to as a “key” (essentially turning it into gibberish). This key effectively decodes the complex code that was created using your data. This key is only known by your computer and the VPN server. Decryption, or the act of making encrypted data readable once more through the use of a key, is the process of decoding your data.

As a common illustration, consider entering your credit card information into a purchasing website. Until it reaches its final destination, the information is encrypted and rendered unreadably.

Although different VPN providers employ various encryption techniques, the basic VPN encryption procedure is as follows:

  • Your data is encrypted when you connect to a VPN through a secure tunnel. As a result, your data is converted into an unintelligible code and sent between your computer and the VPN server.
  • Your device is now perceived as being connected to your VPN’s local network. As a result, the IP address of one of the servers owned by your VPN provider will actually be your IP address.
  • You can use the VPN as a barrier to safeguard your personal information, allowing you to access the internet as you choose.
  • Your VPN provider’s encryption mechanism’s protocols, which we will cover in more detail later, determine how well your data is encrypted.

Types of VPN

The type of software you use will determine how much or how little your VPN impacts your device.

Every app that connects to the internet, such as browsers, banking apps, or social media apps, is protected by many VPNs since they integrate seamlessly with the settings of an operating system, such as Windows, Mac OS, iOS, or Android.

Standalone VPN Services

Namecheap provides the kind of VPN that is most frequently used by homes and small companies. It makes use of a program to establish an encrypted connection to the private network, which you can then use to access the public internet.

Browser Extensions

Some VPNs function as browser extensions. While browsers like Google Chrome or Firefox provide a wide variety of add-ons, Opera already has a VPN built in. The drawback of this is that only when you use that particular browser will your data be safe.

Other applications won’t be shielded. Additionally, IP leaks can happen and browser VPNs tend to be a little more open to attack.

If you do choose to use a browser extension or add-on, it is better to stick with reliable providers that also provide other types of VPN services. There are many dubious browser add-ons available; to avoid a scammy, data harvester, check reviews and always read the terms of service in their entirety.

VPN Routers

By using a router with VPN support, you can implement a VPN in another way. If you wish to protect multiple devices, this is the best option because it will secure every device linked to the router, saving you the trouble of installing the VPN on each one separately. Furthermore, your router will always be linked to your VPN; you just need to sign in once.

The process of connecting your router to a VPN is simpler than you may imagine. You must first join up for a VPN service, and after that, a router is required. The most practical router to purchase is one that is made to support VPNs out of the box, so all you have to do is enter your VPN information. Although these routers can cost a little more than standard routers, the convenience is priceless.
