What Is A VPN?

“What does VPN stand for?” is indeed the most frequently asked question.

VPN stands for virtual private network, which creates a virtual link between your computer and a distant server owned by a VPN service provider.

Additionally, a VPN builds a point-to-point tunnel across the internet that encrypts your private information, masks your IP address, and enables you to get around firewalls and website blockages. 

This guarantees the privacy, security, and protection of your online experiences.

Virtual private network VPN meaning

A VPN connection is:

  • Virtual since there are no actual wires used in the connecting process.

  • Private since no one else can view your browser history or data over this connection.

  • Networked since several devices—your PC and the VPN server—work together to keep a connection established.

When Was the VPN Invented?

Microsoft created the VPN virtual private network in 1996 to allow remote workers to safely access the company's internal network. 

After the approach boosted corporate productivity, other businesses started using it.

As such, remote work supported by corporate VPNs is becoming a commonplace aspect of the global business setting.

When developers discovered that the World Wide Web is the greatest network on the globe, they recognized that regular people might use this secure "tunnel" to easily connect to it.

Nowadays, VPN networks are the mainstay of consumer internet privacy.

Different Types of VPN

Although there are many different kinds of VPNs, the 4 primary types are personal, site-to-site, mobile, and remote access VPNs.

Personal VPN

A personal virtual private network is what most consumer-grade VPNs fall under.

After connecting you to a VPN server, it serves as a go-between for your device and the websites you wish to visit.

Unlike a remote access VPN, a personal VPN doesn't grant you access to a private network,

Through the use of an encrypted connection, it allows you to browse the public internet instead.

Remote access VPN

With a remote access VPN, you may connect to a private network—like the office network of your business—over the Internet.

One unreliable channel for communication is the internet. 

When data is sent to and from a private network, VPN encryption is employed to protect it.

Site-to-site VPN

A site-to-site VPN connects two networks on different sites, but a remote access VPN allows a single user to connect to a network and utilize its services.

Site-to-site VPN

A site-to-site VPN  may be used to link a company's two east and west coast offices into a single network, for instance.

It can be implemented using many technologies, such as L3VPN, IPsec, and Dynamic MultiPoint VPN (DMVPN).

Mobile VPN

In case the user is unlikely to maintain a consistent connection on the same network during the session, a mobile VPN is a preferable choice over a remote access VPN.

Further, when a user uses a mobile virtual private network, the VPN connection endures even if they change WiFi or cellular networks, experience connectivity issues, or turn off their device for an extended period.

So that’s the main types of VPNs. Look at the table below to see the differences between them:

How Does A VPN Work?

A VPN works by using a private service to route a device's internet connection instead of the user's usual internet service provider (ISP). 

Because the VPN hides the user's IP address, it serves as an intermediary between them and the internet.

Whe users use VPN, their device may browse the internet while hiding their personal information, location, and other data over a private, encrypted tunnel.

Via the VPN, all network traffic is routed over a secure connection. 

This implies that instead of coming from the user's computer, any data sent to the internet is routed through the VPN. 

Why Use A VPN?

There are several benefits of VPN for anybody looking for a more free, secure, and safe internet experience.

The following are some typical reasons for using a VPN:

The benefits of using VPN

Secure your data

Particularly over a public network, sensitive data (such as work emails and payment details) is easily trackable and exploitable.

Anybody with network access might be able to view your personal information.

To avoid that, a VPN connection encrypts your data, making it unreadable to anybody lacking an encryption key. 

It makes your browsing activities invisible to other people.

Work from home

As long as they can connect to the internet, remote employees can use a VPN to access business resources from any location. 

This gives them greater flexibility while guaranteeing that corporate information is safe and secure—even while using a public Wi-Fi network.

Access or watch local content

What does a VPN do? It can help you access or watch local content easily. 

Certain types of content might not be available to you as many websites and services limit their media content based on your region.

With the use of a VPN, you may make your local server appear to be situated somewhere else, like another nation, by hiding or spoofing its location.

Bypass censorship and surveillance

Government limitations, censorship, or monitoring may prevent specific areas from accessing particular websites or services. 

Luckily, these individuals can see websites that are restricted, get over firewalls, and browse the internet without restriction thanks to location spoofing.

Beat price discrimination

There are two ways that price discrimination might affect you, one of which is by your position.

Certain businesses set up their websites so that users in places with greater cost of living see a higher cost of items (like airline tickets). 

Another is that your ISP may sell the vendor your information if you are a frequent buyer of the products, and the vendor may raise your price as they know you will purchase it.

Avoid ISP and third-party tracking

Through the unique IP address of your device, ISPs can record and monitor your surfing history for selling to third-party advertisers or leave you open to security compromise.
