VPN (Virtual Private Network) refers to the ability to establish a secure network connection when using public networks. Virtual Private Networks encrypt your internet traffic and conceal your identity online. This makes it more difficult for third parties to follow your internet activities and steal information. The encryption happens in real-time.
How does a VPN work?
A VPN conceals your IP address by routing it through a specially configured distant server maintained by a Virtual Private Network host. This means that if you use a Virtual Private Network to surf the web, the Virtual Private Network server becomes the source of your data. This means that your ISP and other third parties cannot know which websites you visit or what data you send and receive online.
A Virtual Private Network acts as a filter, converting all of your data into “gibberish.” Even if someone were to obtain your data, it would be useless.
What is a VPN app?
A Virtual Private Network, sends all of your internet activities over a private, encrypted connection, preventing others from knowing what and where you’re doing online.
A Virtual Private Network, in essence, adds an extra layer of protection and secrecy to all of your online activity.
What are the benefits of a VPN connection?
A Virtual Private Network connection masks your online data transmission and protects it from prying eyes. Anyone with network access and a desire to read unencrypted data can do so. Hackers and cyber thieves are unable to decode this data when using a Virtual Private Network.
- Secure encryption
- Hide your location
- Access to regional content
- Secure data transfer
Why should you use a VPN connection?
When you connect to the internet, your ISP normally configures your connection.
It follows you using your IP address.
Your network traffic is routed through the servers of your Internet service provider, which can log and display everything you do online.

Your internet service provider may appear trustworthy, but it may disclose your surfing history to advertising, the police or government, and/or other third parties.
ISPs can also be targeted by cybercriminals:
Your personal and confidential information may be compromised if they are hacked.
This is especially critical if you use public Wi-Fi networks frequently.
You never know who is watching your internet activity or what they might steal from you, such as passwords, personal information, financial information, or even your complete identity.
What should a good VPN do?
You should use your Virtual Private Network to complete one or more tasks.
The Virtual Private Network should also be secure against compromise.
A comprehensive Virtual Private Network solution should include the following features:
- IP address encryption: The fundamental function of a Virtual Private Network is to conceal your IP address from your ISP and other third parties.
This allows you to communicate and receive information online without worrying about anyone else seeing it except you and the VPN provider.
- Protocol encryption: A Virtual Private Network should also prevent you from leaving traces, such as internet history, search history, and cookies. Cookie encryption is very significant since it prevents third parties from accessing confidential information such as personal data, financial information, and other website content.
- Kill switch: If your Virtual Private Network connection is unexpectedly terminated, your secure connection will be terminated as well. A decent Virtual Private Network can detect this unexpected downtime and terminate pre-selected apps, limiting the possibility of data compromise.
- Two-factor authentication: A powerful Virtual Private Network examines everyone who tries to log in using several authentication methods. For example, you may be asked to provide a password before receiving a code on your mobile device.
This makes it unwelcome for third parties difficult to gain access to your encrypted connection.
The History of VPNs
There has been a trend to safeguard and encrypt internet browser data since humans began using the internet.
Back in the 1960s, the US Department of Defense was involved in research aimed at encrypting internet connection data.
The predecessors of the VPN
Their efforts resulted in the formation of ARPANET, a packet switching network, which in turn resulted in the development of the Transfer Control Protocol/Internet Protocol (TCP/IP).
TCP/IP was divided into four levels: link, internet, transport, and application. Local networks and devices may be connected to the universal network via the internet, and this is where the risk of exposure became obvious.
In 1993, a team from Columbia University and AT&T Bell Labs succeeded in developing swIPe: Software IP encryption protocol, the earliest version of the current VPN.
Wei Xu created the IPSec network the next year, an internet security protocol that authenticates and encrypts information packets shared online. Gurdeep Singh-Pall, a Microsoft employee, invented the Peer-to-Peer Tunneling Protocol in 1996. (PPTP).
Early VPNs
Concurrent with Singh-development Pall’s of PPTP, the internet’s popularity grew, and the demand for consumer-ready, advanced security systems evolved. Anti-virus software was already successful at preventing malware and spyware from infecting a computer system at the time. However, people and businesses began to seek encryption software that could conceal their internet browsing history.
As a result, the first Virtual Private Networks appeared in the early 2000s but were almost exclusively utilized by businesses.
However, following a slew of security breaches, particularly in the early 2010s, the consumer market for Virtual Private Networks began to heat up.
VPNs and their current use
According to GlobalWebIndex, the number of Virtual Private Network users more than quadrupled between 2016 and 2018.
One in every five internet users in countries where internet access is restricted and regulated, such as Thailand, Indonesia, and China, uses a Virtual Private Network.
The proportion of Virtual Private Network users in the United States, the United Kingdom, and Germany is less than 5%, but it is growing.
The growing need for material with geographical access restrictions has been a major driver of VPN use in recent years.
Specific videos, for example, are only available in certain countries via video streaming services such as Netflix or YouTube. You may encrypt your IP address using a modern Virtual Private Network to appear to be surfing from another country, allowing you to access this content from anywhere.
Here’s how to use a VPN to surf safely.
A VPN encrypts your browsing activity, which can only be deciphered via a key. Because only your computer and the Virtual Private Network have access to this key, your ISP will not be able to determine where you are surfing. Different Virtual Private Networks utilize different encryption methods, however, they all work in three steps:
- Once online, launch your Virtual Private Network. The Virtual Private Network establishes a secure connection between you and the internet. This tunnel is invisible to your ISP and other third parties.
- Your device is now on the Virtual Private Networks local network, and your IP address can be changed to one provided by the Virtual Private Network server.
- You can now freely browse the internet because the Virtual Private Network secures all of your personal information.
What kind of VPNs are there?
There are other varieties of Virtual Private Networks, but you should be familiar with the three most common:
SSL VPN
Often, not all firm employees have access to a company laptop that they can use to work from home.
During the corona crisis in Spring 2020, many businesses confronted the issue of insufficient equipment for their staff. In such instances, the usage of a personal device (PC, laptop, tablet, or mobile phone) is frequently employed.
In this instance, businesses rely on an SSL- Virtual Private Network solution, which is often deployed through a corresponding hardware box.
The standard requirement is an HTML-5-capable browser, which is used to access the company’s login page.
HTML-5 browsers are available for almost every operating system.
A username and password are required to gain access.
Site-to-site VPN
A site-to-site Virtual Private Network is simply a private network designed to conceal private intranets and allow users of these secure networks to access the resources one another.
A site-to-site Virtual Private Network is handy if your firm has numerous locations, each with its local area network (LAN) connected to the wide area network (WAN) (Wide Area Network).
Site-to-site Virtual Private Networks are also beneficial if you have two independent intranets and wish to send files across them without allowing users from one intranet to expressly access the other.
Site-to-site Virtual Private Networks are mostly employed in large organizations. They are difficult to set up and do not provide the same level of flexibility as SSL Virtual Private Networks. They are, however, the most effective means of ensuring communication within and between huge departments.
Client-to-Server VPN
Connecting with a Virtual Private Network client is analogous to connecting your home PC to the company using an extension cable. Employees can use the secure connection to dial into the company network from their home office and act as if they were in the office. A Virtual Private Network client, however, must first be installed and configured on the computer.
This includes the user not connecting to the internet through his or her ISP, but rather through his or her VPN provider. This effectively shortens the Virtual Private Network journey’s tunnel phase. Rather than employing the Virtual Private Network to construct an encryption tunnel to mask the user’s existing internet connection, the Virtual Private Network can automatically encrypt the data before it is made available to the user.
This is a growing type of Virtual Private Network that is especially useful for providers of insecure public WLAN.
It protects the network connection against unauthorized access and encryption to the provider.
It also prohibits ISPs from seeing data that is unencrypted for whatever reason and circumvents any limits on the user’s internet connection (for instance, if the government of that country restricts internet access).
This type of Virtual Private Network connectivity provides increased efficiency and universal access to company resources.
If a suitable telephone system is available, the employee can, for example, use a headset to connect to the system and pretend to be in their company’s workplace.
Customers, for example, are unable to identify whether the individual is working at the company or home.
How do I install a VPN on my computer?
Before establishing a Virtual Private Network, it is critical to understand the various implementation methods:
VPN client
For standalone Virtual Private Network clients, software must be installed.
This software is set up to meet the needs of the endpoint.
When the Virtual Private Network is configured, the endpoint executes the VPN connection and connects to the other endpoint, forming the encryption tunnel. In most cases, this stage needs the entry of a company-issued password or the installation of an applicable certificate. The firewall can recognize an authorized connection by utilizing a password or certificate. The employee then identifies himself/herself using credentials that are familiar to him/her.
Browser Extensions
VPN extensions may be applied to most online browsers, including Google Chrome and Firefox. Some browsers, such as Opera, even have their VPN plugins built in. Users can utilize extensions to rapidly switch and set up their Virtual Private Network while browsing the internet. The VPN connection, however, is only valid for information transferred in this browser.
Other browsers and internet use outside of the browser (for example, online games) are not secured by the Virtual Private Network.
While browser extensions are not as extensive as VPN apps, they may be a good solution for casual internet users looking for an extra layer of security.
They have, however, proven to be more vulnerable to breaches.
Users should also select a trustworthy extension, as data harvesters may attempt to employ bogus VPN extensions.
The acquisition of personal data, such as what marketing strategists do to construct a personal profile of you, is known as data harvesting.
The advertising content is then personalized for you.
Router VPN
If numerous devices are linked to the same internet connection, it may be easier to set up the Virtual Private Network directly on the router rather than on each device separately. A router VPN is especially beneficial if you want to safeguard internet-connected devices that are difficult to configure, such as smart TVs. They can also assist you in gaining access to geographically restricted content via your home entertainment systems.
A router Virtual Private Network is simple to set up, always provides security and privacy, and keeps your network safe when insecure devices connect. However, if your router does not have its user interface, it may be more difficult to manage. Incoming connections may be banned as a result of this.
Company VPN
A company VPN is a tailored solution that necessitates specific configuration and technical support.
The Virtual Private Network is typically set up for you by the company’s IT department.
You have no administrative control over the VPN as a user, and your activity and data transfers are tracked by your organization.
This allows the company to reduce the danger of data leaking.
The primary benefit of a business Virtual Private Network is that it provides a completely secure connection to the company’s intranet and server, even for workers who work outside the company and use their internet connection.
Can I also use a VPN on my smartphone or other devices?
Yes, there are Virtual Private Network services available for cellphones and other internet-connected devices.
If you use your mobile device to store payment information or other personal data, or even merely to browse the internet, a Virtual Private Network is vital.
Many Virtual Private Network providers also provide mobile solutions, such as Kaspersky Virtual Private Network Secure Connection, which can be downloaded directly from Google Play or the Apple App Store.
Is a VPN Safe?
It is critical to understand that Virtual Private Networks do not work as comprehensive anti-virus software.
A Virtual Private Network connection, although protecting your IP and encrypting your internet history, does not safeguard your computer from outside infiltration.
You should utilize anti-virus software, such as Kaspersky Internet Security, to accomplish this.
Because a Virtual Private Network does not protect you from Trojans, viruses, bots, or other malware on its own.
Once the malware has infiltrated your device, it can steal or harm your data regardless of whether you are using a Virtual Private Network.
To achieve optimal protection, you should use a Virtual Private Network in conjunction with a robust anti-virus package.
Selecting a secure VPN provider
It is also critical that you select a Virtual Private Network provider you can rely on. While your ISP will not be able to view your internet traffic, your VPN provider will. If your Virtual Private Network service provider is compromised, you are as well. As a result, you must select a reputable VPN service provider to assure both the concealment of your internet activities and the maximum level of security.

But keep the following in mind
A Virtual Private Network is just as secure as the provider’s data usage and storage practices.
Remember that the VPN service sends your data to their servers, which then connect to the internet on your behalf.
If they keep data logs, make it obvious why.
Serious Virtual Private Network services will usually prioritize your privacy.
As a result, you should use a reputable supplier.
Keep in mind that only internet traffic is encrypted.
Anything not utilizing a cellular or Wi-Fi connection will not be broadcast via the internet.
As a result, your Virtual Private Network will not encrypt normal voice or text messages.
