What is a vpn

You may ask yourself; what Is a VPN? A VPN stands for Virtual Private Network and describes the opportunity to establish a protected network connection while using a public network. A VPN encrypts your internet traffic and disguises your online identity. This makes it harder for third parties to track your online activity and Steal data. Encryption happens in real time.

How does a VPN work?

A VPN hides your IP address by having the network redirect it through a specially configured remote server run by the VPN host. This means that if you use a VPN to surf online, the VPN server will be your data source. This means that your Internet Service Provider (ISP) and other third parties cannot See which websites you visit or what data is sent and received online. A VPN acts like a filter that turns all your data into gibberish. Even if someone gets your data, it’s useless.

What are the benefits of a VPN connection?

A VPN connection disguises your online data traffic and protects it from outside access. The unencrypted data can be viewed by anyone with network access and who wishes to view it. This data cannot be deciphered by hackers and cybercriminals using a VPN.

 Secure encryption: To read data, you need an encryption key. Without it, it would take millions of years for a computer to decipher the code in the event of a brute force attack. With the help of a VPN, your online activities are hidden even on public networks.

 Disguising your whereabouts: A VPN server essentially acts as a proxy for you on the Internet. Since the demographic location data comes from a server in another country, your actual location cannot be determined. Also, most VPN services do not store logs of your activity. On the other hand, some providers log your conduct, but do not pass this information on to third parties. This means that any potential records of your user behavior are permanently hidden.

 Access to regional content:  Regional web content is not always accessible from anywhere. The Services and Websites often contain content that is only accessible from certain regions of the world. A standard connection uses a country-local server to determine your location. This means you can’t access content from home You can’t access international content at home while you’re on the go. With VPN location spoofing, you can switch servers to another country and effectively “change” your location.

 Secure data transfer:  If you work remotely, you may need to access important files on your company network. For security reasons, such information requires a secure connection. To access the web, a VPN connection is usually required. VPN service connects to a private server and uses encryption Ways to reduce the risk of data breaches.

Why should you use a VPN connection?

Your ISP usually sets up your connection when you connect to the Internet. It tracks you by IP address. Your web traffic is routed through your ISP’s servers, which record and display everything you do online.

Your ISP may appear trustworthy, but it may share your browsing history with advertisers, the police or government and/or other third parties. ISPs can also fall victim to attacks by cybercriminals: if they get hacked, your personal and private data can be compromised.

This is especially important if you frequently connect to public Wi-Fi networks. You never know who might be monitoring your internet traffic and what they might be stealing from you, including passwords, personal data, payment information or even your entire identity.

What should a good VPN do?

You should rely on your VPN for one or more tasks. The VPN itself should also be protected from compromise. These are the features you should expect from a comprehensive VPN solution:

  • Encrypt your IP address:The main job of a VPN is to hide your IP address from your ISP and other third parties. This allows you to send and receive information online without the risk of being seen by anyone but you and the VPN provider.
  •  Encryption of protocols:  A VPN should also prevent you from leaving traces in the form of internet history search history and cookies. Encryption of cookies is particularly important as it prevents access by third parties to confidential information such as personal data, financials, etc. Information and Other Content on the Site.
  •  Kill switch: If your VPN connection suddenly drops, so will your secure connection. A good VPN can detect this sudden downtime and terminate the preselection process, reducing the chances of a data breach.
  •  Two-factor authentication: By using various authentication methods, a strong VPN can check everyone trying to log in. For example, you may be prompted for a passcode and a code sent to your mobile device. This makes it difficult for uninvited third parties to gain access to your secure connection.

The history of VPNs

Since humans have been using the internet, there has been a movement to secure and encrypt internet browser data. As far back as the 1960s, the U.S. Department of Defense has been involved in data encryption programs for Internet communications.

The predecessors of the VPN

Their efforts led to the creation of ARPANET (Advanced Research Projects Agency Network), a packet-switched network that led to the development of Transmission Control Protocol/Internet Protocol (TCP/IP).

TCP/IP has four layers: linking Internet transport and applications. At the Internet level, local networks and devices can connect to the general network—and this is where the risk of exposure becomes apparent. In 1993, a team at Columbia University and AT&T Bell Labs finally Successfully created the first version of a modern VPN called swIPe: the Software IP Encryption Protocol.

The following year, Xu developed IPSec networking, an internet security protocol that authenticates and encrypts packets of information shared online. In 1996, a Microsoft employee named Gurdeep Singh-Pall created the Peer-to-Peer Tunneling Protocol (PPTP).

Early VPNs

As Singh-Pall developed PPTP, the Internet grew in popularity and a need arose for sophisticated security systems that were consumer-ready. Back then antivirus programs were already effective at preventing malware and spyware from infecting computer systems. However, people and Companies have also started requiring encryption software to hide their browsing history on the Internet.

So, the first VPNs started in the early 2000s, but were used almost exclusively by corporations. However, after numerous security breaches, especially in the early 2010s, the consumer market for VPNs started to pick up.

VPNs and their current use

According to GlobalWebIndex, the number of VPN users worldwide more than quadrupled between 2016 and 2018. In countries where internet use is restricted and censored, such as Thailand, Indonesia, and China, one in five internet users use a VPN. in the US UK and Germany, The percentage of VPN users is low, around 5%, but growing.

One of the biggest drivers of VPN adoption in recent years has been the increasing demand for content with geographically restricted access. For example, video streaming services like Netflix or YouTube make certain videos only available in certain countries. With a modern VPN, you can Encrypts your IP address to make it appear that you are surfing the web from another country, allowing you to access this content from anywhere.

Here’s how to stay safe online with a VPN

A VPN encrypts your surfing, which can only be decoded with the help of a key. Only your computer and the VPN know this key, so your ISP cannot tell where you are surfing the Internet. Different VPNs use different encryption processes, but generally there are three steps:

  1. Once you are online start your VPN. A VPN acts as a secure tunnel between you and the internet. Your ISP and other third parties cannot detect this tunnel.
  2. Your device is now on the VPN’s local network and your IP address can be changed to the one provided by the VPN server.
  3. You can now surf the web as much as you want because a VPN will protect all your personal data.

What kind of VPNs are there?

There are many different types of VPNs, but there are three main types you should definitely be familiar with:


Often not all employees in a company have access to company laptops that they can use to work from home. During the corona crisis in spring 2020, many companies faced the problem of not having enough equipment for their employees. In this case, using a personal device (PC Laptop Tablet Phone) is Often resorted to. In such cases, companies turn to SSL-VPN solutions, usually implemented through corresponding hardware boxes.

A prerequisite is usually an HTML-5 capable browser for calling the company’s login page. Browsers that support HTML-5 are available for almost any operating system. Access is protected by username and password.

Site-to-site VPN

A site-to-site VPN is essentially a private network designed to hide private intranets and allow users of these secure networks to access each other’s resources.

A site-to-site VPN is useful if you have multiple locations in your company, each with its own local area network (LAN) connected to a WAN (wide area network). A site-to-site VPN is also useful if you have two separate intranets, and you want to send files between the two without users from one intranet Explicit access to another.

Site-to-site VPNs are mostly used in large companies. They are complex to implement and do not offer the same flexibility as SSL VPNs. However, they are the most effective way of ensuring communication within and between large departments.

Client-to-Server VPN

Think of connecting through a VPN client as if you were using an extension cord to connect your home PC to work. Employees can dial into the corporate network from their home office over a secure connection, just as if they were sitting in the office. However, the VPN client must first Install and configure on your computer.

This involves the user not connecting to the internet through his own ISP but establishing a direct connection through his/her VPN provider. This essentially shortens the tunneling phase of the VPN journey. Instead of using a VPN to create an encrypted tunnel to disguise the existing Internet Connecting to a VPN can automatically encrypt data before it is served to the user.

This is an increasingly common form of VPN that is especially useful with unsecured public WLAN providers. It prevents third parties from accessing and disrupting network connections and encrypts data all the way to the provider. It also prevents ISPs from accessing data for any reason reason remains unencrypted and bypasses any restrictions on the user’s internet access (for example, if the country’s government restricts internet access).

The advantage of this type of VPN access is that it is more efficient and provides universal access to corporate resources. If a suitable phone system is available, the employee can use a headset to connect to the system, just as he or she would at the corporate workplace. E.g the company’s customers can’t even tell if the employee works for the company or from their home office.

How do I install a VPN on my computer?

Before installing a VPN, it is important to be familiar with the different implementation methods:

VPN client

Software must be installed for standalone VPN clients. This software is configured to meet the requirements of the endpoint. When setting up a VPN, an endpoint performs a VPN link and connects to another endpoint creating an encrypted tunnel. In companies, this step usually requires entering company-issued password or install an appropriate certificate. By using a password or certificate, the firewall can recognize that this is an authorized connection. The employee then identifies him/herself by his/her known credentials.

Browser extensions

VPN extensions can be added to most web browsers such as Google Chrome and Firefox. Some browsers, including Opera, even have their own integrated VPN extensions. The extension makes it easier for users to quickly switch and configure their VPN while surfing the web. But the VPN connection is Only valid for information shared within this browser. Use of other browsers and other Internet usage outside of browsers, such as online gaming, cannot be encrypted through a VPN.

While browser extensions are not as comprehensive as VPN clients, they may be a suitable option for the occasional internet user who needs an extra layer of internet security. However, they have proven to be more vulnerable to breaches. Users are also advised to choose a reputable extension Data collectors may try to use fake VPN extensions. Data harvesting is the collection of personal data, such as what a marketing strategist does to create your profile. Then tailor the ad content just for you.

Router VPN

If multiple devices are connected to the same internet connection, it may be easier to implement a VPN directly on the router than to install a separate VPN on each device. Router VPNs are especially useful if you want to protect your device over an internet connection that is not easily configured Such as smart TV. They even help you access geo-restricted content through your home entertainment system.

Router VPN is easy to install, provides security and privacy at all times, and prevents your network from being compromised when unsecured devices log in. However, if your router doesn’t have its own user interface, it can be more difficult to manage. This may cause incoming connections to be blocked.

Company VPN

A corporate VPN is a custom solution that requires individual setup and technical support. VPNs are usually created for you by your company’s IT team. As a user, you are not under the governance of the VPN itself, and your activities and data transfers are logged by your company. this Enables companies to minimize the potential risk of data breaches. The main advantage of a corporate VPN is completely secure connections to a company’s intranet and servers, even for employees working outside the company using their own internet connections.

Can I also use the VPN on my smartphone or other device?

Yes, there are many VPN options for smartphones and other internet-connected devices. If you use a VPN to store payment information or other personal data, or even just to surf the web, a VPN may be essential for your mobile device. Many VPN providers also offer mobile solutions – many Downloads such as P33k@boo VPN‘s Secure Connection can be downloaded directly from Google Play.

Is a VPN really so secure?

It’s important to note that a VPN doesn’t function like a comprehensive antivirus. While they protect your IP and encrypt your internet history, a VPN connection does not protect your computer from outside intrusion. For this, you should definitely use an antivirus such as Kaspersky cyber security. Because a VPN alone won’t protect you from Trojan horse virus bots or other malware.

Once malware is on your device, it can steal or corrupt your data, whether you’re running a VPN or not. That’s why it’s important to use a VPN with a comprehensive antivirus program for maximum security.

Selecting a secure VPN provider

It is also important to choose a trustworthy VPN provider. While your ISP cannot see your internet traffic, your VPN provider can. If your VPN provider has been hacked, so have you. Therefore, it is crucial to choose a trustworthy VPN provider to keep your privacy safe. Internet activity and ensure the highest level of security.

How to Install a VPN Connection on Your Smartphone

As mentioned, there are also VPN connections available for Android smartphones and iPhones. Fortunately, smartphone VPN services are easy to use and typically include the following:

  • The installation process usually only downloads an app from the iOS App Store or Google Play Store. Although free VPN providers exist, it is wise to choose a professional provider when it comes to security.
  • The setting is very user-friendly, as the default settings are mostly designed for the average smartphone user. Just log in with your account. Most apps will then walk you through the main functions of the VPN service.
  • For many VPN apps, turning on the VPN is like a light switch. You may find this option directly on the home screen.
  • If you want to fake your location, server switching is usually done manually. Simply select the desired country from the quote.
  • Users who require a higher degree of data protection can use the advanced settings. Depending on your VPN, you can also choose other protocols for your encryption method. Your application may also provide diagnostic and other functionality. Learn about these features before you subscribe to find The right VPN for your needs.
  • In order to surf the web safely from now on, all you have to do is first activate a VPN connection through the app.

But keep the following in mind: A VPN is only as secure as its provider’s data usage and storage policies. Remember, VPN services transfer your data to their servers, which connect through the internet on your behalf. If they store data logs, make sure it is clear what they are storing them for. Serious VPN providers usually put your privacy first. Therefore, you should choose a trusted provider such as Kaspersky Secure Connection.

Remember, only internet data is encrypted. Any content not using a cellular or Wi-Fi connection will not be transmitted over the Internet. So your VPN won’t encrypt your standard voice calls or text messages.


A VPN connection creates a secure connection between you and the internet. With a VPN, all your data traffic is routed through an encrypted virtual tunnel. This disguises your IP address when you use the internet so that no one can see where it is. VPN connections are also secure external attack. That’s because only you have access to the data in the encrypted tunnel — no one else because they don’t have the key. A VPN allows you to access region-restricted content from anywhere in the world. Many streaming platforms are not available in every country nation. You can still access them with a VPN. P33k@boo VPN solutions are available for Windows PCs and Android.
