VPN stands for "Virtual Private Network" & describes the opportunity khổng lồ establish a protected network connection when using public networks. VPNs encrypt your mạng internet traffic and disguise your online identity. This makes it more difficult for third parties khổng lồ track your activities online và steal data. The encryption takes place in real time.

How does a VPN work?

A VPN hides your IP address by letting the network redirect it through a specially configured remote vps run by a VPN host. This means that if you surf online with a VPN, the VPN vps becomes the source of your data. This means your mạng internet Service Provider (ISP) và other third parties cannot see which websites you visit or what data you send & receive online. A VPN works lượt thích a filter that turns all your data into "gibberish". Even if someone were to get their hands on your data, it would be useless.

What are the benefits of a VPN connection?

A VPN connection disguises your data traffic online & protects it from external access. Unencrypted data can be viewed by anyone who has network access và wants lớn see it. With a VPN, hackers and cyber criminals can’t decipher this data.

Secure encryption: to lớn read the data, you need an encryption key . Without one, 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 : VPN servers essentially act as your proxies on the internet. Because the demographic location data comes from a vps in another country, your actual location cannot be determined. In addition, most VPN services vày not store logs of your activities. Some providers, on the other hand, record your behavior, but bởi not pass this information on to third parties. This means that any potential record of your user behavior remains permanently hidden.

Access to regional content: Regional web nội dung is not always accessible from everywhere. Services và websites often contain content that can only be accessed from certain parts of the world. Standard connections use local servers in the country lớn determine your location. This means that you cannot access content at home while traveling, & you cannot access international content from home. With VPN location spoofing , you can switch lớn a server 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’s network. For security reasons, this kind of information requires a secure connection. To gain access khổng lồ the network, a VPN connection is often required. VPN services connect khổng lồ private servers và use encryption methods lớn reduce the risk of data leakage.


Why should you use a VPN connection?

Your ISP usually sets up your connection when you connect to lớn the internet. It tracks you via an IP address. Your network traffic is routed through your ISP"s servers, which can log and display everything you vày online.

Your ISP may seem trustworthy, but it may nội dung your browsing history with advertisers, the police or government, and/or other third parties. ISPs can also fall victim to lớn attacks by cyber criminals: If they are hacked, your personal & private data can be compromised.

This is especially important if you regularly connect to lớn public Wi-Fi networks. You never know who might be monitoring your mạng internet traffic and what they might steal 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 to lớn perform one or more tasks. The VPN itself should also be protected against compromise. These are the features you should expect from a comprehensive VPN solution:

Encryption of your IP address: The primary job of a VPN is lớn hide your IP address from your ISP and other third parties. This allows you khổng lồ send và receive information online without the risk of anyone but you và the VPN provider seeing it.Encryption of protocols: A VPN should also prevent you from leaving traces, for example, in the size of your internet history, search history & cookies. The encryption of cookies is especially important because it prevents third parties from gaining access lớn confidential information such as personal data, financial information và other nội dung on websites.Kill switch: If your VPN connection is suddenly interrupted, your secure connection will also be interrupted. A good VPN can detect this sudden downtime và terminate preselected programs, reducing the likelihood that data is compromised.Two-factor authentication: By using a variety of authentication methods, a strong VPN checks everyone who tries lớn log in. For example, you might be prompted to lớn enter a password, after which a code is sent khổng lồ your điện thoại device. This makes it difficult for uninvited third parties lớn access your secure connection.

The history of VPNs

Since humans have been using the internet, there has been a movement to lớn protect và encrypt internet browser data. The US Department of Defense already got involved in projects working on the encryption of mạng internet communication data back in the 1960s.

The predecessors of the VPN

Their efforts led khổng lồ the creation of ARPANET (Advanced Research Projects Agency Network), a packet switching network, which in turn led to the development of the Transfer Control Protocol/Internet Protocol (TCP/IP).

The TCP/IP had four levels: Link, internet, transport and application. At the internet level, local networks and devices could be connected to the universal network – và this is where the risk of exposure became clear. In 1993, a team from Columbia University & AT&T Bell Labs finally succeeded in creating a kind of first version of the modern VPN, known as swIPe: Software IP encryption protocol.

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

Early VPNs

Contiguous to Singh-Pall developing PPTP, the mạng internet was growing in popularity và the need for consumer-ready, sophisticated security systems emerged. At that time, anti-virus programs were already effective in preventing malware and spyware from infecting a computer system. However, people & companies also started demanding encryption software that could hide their browsing history on the internet.

The first VPNs therefore started in the early 2000s, but were almost exclusively used by companies. However, after a flood of security breaches, especially in the early 2010s, the consumer market for VPNs started to lớn pick up.

VPNs và their current use

According to lớn the GlobalWebIndex, the number of VPN users worldwide increased more than fourfold between năm 2016 and 2018. In countries such as Thailand, Indonesia và China, where mạng internet use is restricted & censored, one in fiveinternet users uses a VPN. In the USA, Great Britain & Germany, the proportion of VPN users is lowerat around 5%, but is growing.

One of the biggest drivers for VPN adoption in recent years has been the increasing demand for content with geographical access restrictions. For example, clip streaming services such as Netflix or YouTube make certain videos available only in certain countries. With contemporary VPNs, you can encrypt your IP address so that you appear lớn be surfing from another country, enabling you lớn access this content from anywhere.

Here’s how khổng lồ surf securely with a VPN

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

Once you are online, start your VPN. The VPN acts as a secure tunnel between you & the internet. Your ISP và other third parties cannot detect this tunnel.Your device is now on the local network of the VPN, & your IP address can be changed to an IP address provided by the VPN server.You can now surf the internet at will, as the VPN protects all your personal data.

What kind of VPNs are there?

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


Often not all employees of a company have access khổng lồ a company laptop they can use to lớn work from home. During the corona crisis in Spring 2020, many companies faced the problem of not having enough equipment for their employees. In such cases, use of a private device (PC, laptop, tablet, điện thoại phone) is often resorted to. In this case, companies fall back on an SSL-VPN solution, which is usually implemented via a corresponding hardware box.

The prerequisite is usually an HTML-5-capable browser, which is used to gọi up the company"s login page. HTML-5 capable browsers are available for virtually any operating system. Access is guarded with a username and password.

Site-to-site VPN

A site-to-site VPN is essentially a private network designed to lớn hide private intranets & 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 lớn the WAN (Wide Area Network). Site-to-site VPNs are also useful if you have two separate intranets between which you want khổng lồ send files without users from one intranet explicitly accessing the other.

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

Client-to-Server VPN

Connecting via a VPN client can be imagined as if you were connecting your trang chủ PC lớn the company with an extension cable. Employees can dial into the company network from their trang chủ office via the secure connection and act as if they were sitting in the office. However, a VPN client must first be installed and configured on the computer.

This involves the user not being connected to the mạng internet via his own ISP, but establishing a direct connection through his/her VPN provider. This essentially shortens the tunnel phase of the VPN journey. Instead of using the VPN lớn create an encryption tunnel to lớn disguise the existing mạng internet connection, the VPN can automatically encrypt the data before it is made available khổng lồ the user.

This is an increasingly common form of VPN, which is particularly useful for providers of insecure public WLAN. It prevents third parties from accessing & compromising the network connection and encrypts data all the way khổng lồ the provider. It also prevents ISPs from accessing data that, for whatever reason, remains unencrypted & bypasses any restrictions on the user"s internet access (for instance, if the government of that country restricts mạng internet access).

The advantage of this type of VPN access is greater efficiency and universal access to lớn company resources. Provided an appropriate telephone system is available, the employee can, for example, connect to the system with a headset và act as if he/she were at their company workplace. For example, customers of the company cannot even tell whether the employee is at work in the company or in their home office.

How vày I install a VPN on my computer?

Before installing a VPN, it is important khổng lồ 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 the VPN, the endpoint executes the VPN link and connects lớn the other endpoint, creating the encryption tunnel. In companies, this step usually requires the entry of a password issued by the company or the installation of 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 means of credentials known khổng lồ him/her.

Browser extensions

VPN extensions can be added khổng lồ most web browsers such as Google Chrome & Firefox. Some browsers, including Opera, even have their own integrated VPN extensions. Extensions make it easier for users to quickly switch & configure their VPN while surfing the internet. However, the VPN connection is only valid for information that is shared in this browser. Using other browsers và other internet uses outside the browser (e.g. Online games) cannot be encrypted by the VPN.

While browser extensions are not quite as comprehensive as VPN clients, they may be an appropriate option for occasional mạng internet users who want an extra layer of mạng internet security. However, they have proven khổng lồ be more susceptible to breaches. Users are also advised to choose a reputable extension, as data harvesters may attempt to use giả VPN extensions. Data harvesting is the collection of personal data, such as what sale strategists vày to create a personal profile of you. Advertising content is then personally tailored lớn you.

Router VPN

If multiple devices are connected khổng lồ the same mạng internet connection, it may be easier to implement the VPN directly on the router than khổng lồ install a separate VPN on each device. A router VPN is especially useful if you want to protect devices with an internet connection that are not easy to configure, such as smart TVs. They can even help you access geographically restricted nội dung through your home entertainment systems.

A router VPN is easy to lớn install, always provides security & privacy, and prevents your network from being compromised when insecure devices log on. However, it may be more difficult lớn manage if your router does not have its own user interface. This can lead khổng lồ incoming connections being blocked.

Company VPN

A company VPN is a custom solution that requires personalized thiết đặt and technical support. The VPN is usually created for you by the company"s IT team. As a user, you have no administrative influence from the VPN itself and your activities và data transfers are logged by your company. This allows the company lớn minimize the potential risk of data leakage. The main advantage of a corporate VPN is a fully secure connection to the company"s intranet & server, even for employees who work outside the company using their own internet connection.

Can I also use a VPN on my điện thoại thông minh or other devices?

Yes, there are a number of VPN options for smartphones & other internet-connected devices. A VPN can be essential for your mobile device if you use it lớn store payment information or other personal data or even just to lớn surf the internet. Many VPN providers also offer điện thoại solutions - many of which can be downloaded directly from Google Play or the Apple ứng dụng Store, such as nuhoangthoitrang.vn VPN Secure Connection.

Is a VPN really so secure?

It is important to note that VPNs bởi not function like comprehensive anti-virus software. While they protect your IP and encrypt your mạng internet history, a VPN connection does not protect your computer from outside intrusion. To vày this, you should definitely use anti-virus software such as nuhoangthoitrang.vn internet Security . Because using a VPN on its own does not protect you from Trojans, viruses, bots or other malware.

Once the malware has found its way onto your device, it can steal or damage your data, whether you are running a VPN or not. It is therefore important that you use a VPN together with a comprehensive anti-virus program to lớn ensure maximum security.

Selecting a secure VPN provider

It is also important that you choose a VPN provider that you can trust. While your ISP cannot see your internet traffic, your VPN provider can. If your VPN provider is compromised, so are you. For this reason, it is crucial that you choose a trusted VPN provider lớn ensure both the concealment of your internet activities và ensure the highest cấp độ of security.

How lớn install a VPN connection on your smartphone

As already mentioned, there are also VPN connections for apk smartphones & iPhones. Fortunately, điện thoại cảm ứng thông minh VPN services are easy to use và generally include the following:

The installation process usually only downloads one app from the iOS app Store or Google Play Store. Although không tính phí VPN providers exist, it’s wise to lớn choose a professional provider when it comes khổng lồ security.The setup is extremely user-friendly, as the default settings are already mostly designed for the average điện thoại cảm ứng user. Simply log in with your account. Most apps will then guide you through the key functions of the VPN services.Switching on the VPN literally works like a light switch for many VPN apps. You will probably find the option directly on the trang chủ screen.Server switching is usually done manually if you want to giả your location. Simply select the desired country from the offer.Advanced setup is available for users requiring a higher degree of data protection. Depending on your VPN, you can also select other protocols for your encryption method. Diagnostics và other functions may also be available in your app. Before you subscribe, learn about these features khổng lồ find the right VPN for your needs.In order to surf the internet safely from now on, all you have to vày is first activate the VPN connection through the app.

But keep the following in mind: A VPN is only as secure as the data usage and storage policies of its provider. Remember that the VPN service transfers your data to lớn their servers và these servers connect over the internet on your behalf. If they store data logs, make sure that it is clear for what purpose these logs are stored. Serious VPN providers usually put your privacy first và foremost. You should therefore choose a trusted provider such as nuhoangthoitrang.vn Secure Connection .

Remember that only mạng internet data is encrypted. Anything that does not use a cellular or Wi-Fi connection will not be transmitted over the internet. As a result, your VPN will not encrypt your standard voice calls or texts.


A VPN connection establishes a secure connection between you & the internet. Via the VPN, all your data traffic is routed through an encrypted virtual tunnel. This disguises your IP address when you use the internet, making its location invisible lớn everyone. A VPN connection is also secure against external attacks. That’s because only you can access the data in the encrypted tunnel – và nobody else can because they don’t have the key. A VPN allows you to access regionally restricted nội dung from anywhere in the world. Many streaming platforms are not available in every country. You can still access them using the VPN. VPN solutions from nuhoangthoitrang.vn are available for both Windows PCs and Apple Macs.

There are now also many providers of VPN connections for smartphones which keep thiết bị di động data traffic anonymous. You can find certified providers in the Google Play Store or the iOS tiện ích Store. However, remember that only your data traffic on the mạng internet is anonymized và protected by using a VPN. The VPN connection does not protect you from hacker attacks, Trojans, viruses or other malware. You should therefore rely on an additional trusted anti-virus software.
