What is a VPN?

VPN definition

VPN expands private network across a shared or public network. It allows the users to get and receive information across shared networks, like, the computing devices used by them were connected to the private network directly. Therefore the benefits which applications are running across a VPN are management, security and functionality of the private network.

In simple words, a VPN connects your tablet, smartphone, or PC to the server ( or another computer) on the Internet, and permits your surfing the Internet using that computer’s connection. Hence, if that server is in another country, it will look like you are coming from that country, and you can get access to the things that generally, you couldn’t.

The purpose of developing a VPN was making corporate applications and resources accessible to remote users, mobile users, and to branch offices. Users may have to pass various authentication for getting access to the VPN, and encrypted layered tunnelling protocol may be used to establish a network connection for security reasons. For keeping personal identity and location, safe and anonymous users may make their connections safe with a VPN to circumvent geo-blocking and censorship or to connect to proxy servers in other applications. However, to prevent avoid ion of geo-restrictions, some Websites block access to known IP addresses used by VPNs

For creating a VPN, a virtual point-to-point connection is made by using dedicated circuits or with tunnelling protocols over existing NETWORKS. Some of the benefits of WAN (Wide area network) can be provided by A VPN available from the public Internet.

Types of VPN

Mainly, there are three main types of VPNs, i.e. remote access, intranet-based site-to-site, and extranet-based site-to-site. Individual users often interconnect with remote-access VPNs; businesses use site-to-site VPNs more frequently.

Earlier, VPN-style connections were permitted to remote places by leased line connections using X.25, ATM virtual circuits and frame relay made available by telecommunication carriers owned and operated networks or via dial-up modem. As these secure data by creating logical data streams, passively, these can’t be called as true VPNs. Because of the reduced costs and increased bandwidth by latest technologies VPNs based on IP and IP/Multi-protocol Label Switching (MPLS) Networks have replaced this dial-up modem one or other earlier.

For connecting a single computer and the network, it can be characterized as host-to-network, and for connecting two networks, it can be described as site-to-site. Remote-access VPNs permits employees to have access to the company’s intranet from outside the office, in a corporate setting. Site-to-site VPNs allow the sharing of the same network of collaborators in geographically disparate offices. It can also connect two same networks over a different intermediate network.

Why do I need VPN service?

One of the essential advantages of VPN is that it keeps data safe and secure and maintains the privacy of online activities. There are some organisations which can keep an eye on your all online activities if they want to. When you surf the web or work on an unsecured Wi-Fi network, there is a risk of exposing your private information or browsing habits. Thus, for online privacy and security, one must think about having one. As if you are working on an unsecured Wi-Fi network, then any of your essential data used during that online session can be vulnerable to the strangers using the same network as yours.

When you connected your device to a public Wi-Fi network, the biggest worry is of security and privacy. And you can’t say what level of protection these public connections are providing. Some of them can even steal your important data and information through these public connections. But at such time you definitely will feel relaxed if you are using a VPN. And online banking is not suggested on these public connections without VPN. A VPN encrypts your data; this increases the level of security. And some of them provide extra security features like protection from malware also. Your online activities, like online shopping, bill payments and sending and receiving emails, are protected by the anonymity and encryption provided by VPN. VPN also ensures that web browsing remains anonymous.

You may need to connect to an internal network at work if working in any corporate office. A VPN allows easy connection to the office network and work remotely. You can get any required confidential information which could be earlier found in office only. And it is safe too as the data is encrypted when it travels. But the corporate VPNs which connect to office networks and the consumer-grade services which are for personal use are quite different. Manual set up of VPN on the device will be required to confirm that you have access to the office network. Many VPN services promise they can help you circumvent geolocation restrictions which make it in more demand. Many streaming services, subscriptions, software and online booking rates are different in different parts of the world. And there are chances of finding all these at a cheaper rate.

You might have come across expansive claims about how a VPN can help you save thousands of dollars. You can supposedly do so by finding cheaper subscription plans for software, streaming services, and other apps and programs. Even airfare, rental car rates, and hotel prices could be much less high when using a VPN. But there is a significant risk and a great chance of failure too in this advantage.

Why is VPN secure?

From ISP and cybercriminals, VPNs secure your public internet connection by shielding your online activity and encrypting your data and information. And almost every VPNs are clear about their privacy policies. When you enter a website address, ISP taps into the router to forward your internet traffic to that website. ISP assigns an Internet Protocol (IP) address to the router and to each device connected to that router. For marketing purpose, some websites, ad networks, and platforms use this IP address for tracking location information.

But on using software, the device connects to the servers of VPN provider. The internet traffic passes through the internet connection of VPN, that means private information is protected and hidden from ISP and websites so they can’t log web surfing. The VPN server mixes your web traffic with others on the server; in this way, your IP address seems similar to one associated with the VPN. And all this make gathering information about you and what you are doing online more complicated.

Now many people believe that private browsing will also work significantly for them, and it can protect the devices from viruses, malware, theft and fraud and hacking attempts, as local data will not be stored. But it is not valid. Private browsing can stop the browser from storing device information, but it doesn’t take guarantee of sharing between device and ISP. And some chances third parties can get traces of activities.  And hence the only secure way is VPN.

What does VPN hide?

A VPN will hide the user’s IP address and block their browsing history and location and allows sharing and receiving information and data on public internet networks in a more private way. Your cookies, cached data, and cookies are the digital footprints left behind by a user while web surfing or communicating online. And ISP, Government, and some other third parties like some website or Google or some hackers or cybercriminals can track what you searched, visit, and download.

And your IP address can be collected in private browsing mode also. When enabling a VPN before surfing, it ensures online privacy and increased security. Any third party or anyone else will be able to see the IP address of the remote VPN. This will not allow accessing your location, browser history, or personal information.

  1. Web browsing activities
  2. From a browser, you can remove search and cookies history. But still, your ISP has recorded the visited websites. And VPNs can hide browsing activity, like websites visited, searched terms, links clicked, and search history. It can also mask your IP address. You are removing the file references from your directories, but these data will not be deleted from your operating system. It will be moved to a particular area on your device. And if you are using a VPN every time you surf the web. This feature disables them from getting and tracking your location, ISP and, other personal information.
  • IP address
  • What identifies your device on the Internet or a local network is your IP address. And this IP address is the key to your every information, your location, ISP, and web search history. Sensitive information related to you, including your physical location, city, state, ZIP code, state and country can be shared by IP addresses. It can trackback to your home ISP, revealing your name, home address, phone number, and credit card numbers.
  • Location
  • We know that the IP address can identify your geolocation. Browsers and websites use this information and data to map web traffic from different cities, states, and countries. Like, while using Google Maps, you must enable your phone to detect location. Websites use this same technology. One of the critical benefits of a VPN is geo-spoofing. VPN makes others fool; it will show a different location than yours.
  • Device
  • By masking IP address, VPN can hide your online identity. It encrypts your data location used online and thus helps in protecting personally identifiable information. And If a hacker somehow gets access to your computer, your PII could be vulnerable. You can secure many other things like medical diagnosis and condition and travel accommodations too. It can hide your device and every information stored in your device.

How to choose the right VPN for me?

Everyone has different needs, and everyone expects different from a VPN. And the most important thing for this is finding what do you want or expect from VPN and knowing what criteria do you want to be fulfilled. Many measures can distinguish VPN services from each other. These include: Some unique IP addresses, Number of individual countries, Number of servers, Number of simultaneous connections, Devices and apps, Protocols, Logging and jurisdiction, Kill switch, Speed, Trail period and Price.

Each of these factors may affect your decision less or more into your purchase decision, based on your own needs. Let’s take a look a what matters most.

Trial Period

Trial period is one of the most important primary and initial aspects in choosing a VPN service. Sometimes, it is the period where you are allowed to use the service and get a refund if you don’t like it good enough for your needs and request a refund or you’re allowed to use the service without any charge.

Whatever is the case, it merely means it is the duration when you try to decide that the service is fulfilling your requirements and is right for you or not. And this is one of the essential factors in getting a VPN for you. The only way through which you can get satisfied if a VPN is right for you is testing it yourself. And that’s the reason why the trial period is so critical, and also why we tend to rate VPN services with more extended trial periods higher when we recommend them.

All those numbers

Whenever you see and list of VPN services, you will find numbers that describe the number of locations, countries, servers, and IP addresses. To some extent, this information is useful in gauging the scope of a VPN provider’s network. But this necessary information might not be that important.

Sometimes, VPN services tell that the number of IP addresses increases anonymity. The reason for that is an IP address is less likely to be reused if there are many. The smaller services have fewer customers, and hence your IP addresses and similarly the most extensive services have the largest number of customers and therefore many IP addresses. But in reality, you can be using a recently used IP address despite a large number of IP addresses.

Several exit points on the network of VPN provider is described by the number of locations countries and servers.

Usually, one should pay more attention on, if the VPN provider one wants to have has a large number of servers in the country one wants to access or not, not on the number of overall service countries and locations the VPN provider has.

And here once again be felt the need of trial period. Without trying the VPN Service Provider, we can’t 13 that it has a good number of service in the interested country or not.

Number of simultaneous connections

Several simultaneous connections are different from what we saw earlier and the bigger the number of concurrent connection, the better it is. This is the number which controls how many devices you have connected at one time.

Device support and VPN apps

Almost all VPNs have clients from users of different software and different devices. But it can not be stated that a VPN can have facilities for all the software available in the market; for example, many must not have facilities for the uses of Linux. At the same time, some provide facilities for setup boxes and routers too. And you must know that the VPN you are interested in works for your device or your or not.


The reality is this that some Communication protocols give better protection and security when compared to others. At the same time, some are made earlier and are old and hence are broken in general cases. VPN providers provide protocols which are secure for their customers. But if you ask someone who wants guaranteed privacy, then you must do some research by yourself.

Logging and jurisdiction

Primary connection and billing information and details surfing information are the two types of data logged by VPN vendors. Many people do not prefer the VPN vendor that logs detailed surfing information as this can be sold for marketing purpose, and even the government can have access to these surfing data. And it this is also right that everything promised by a provider is not right and proper. So, you must checkthe vpn if you want to hide your identity on a deep level.

Kill switch

Kill switch is the capability of a VPN client app to stop sending information as soon as the VPN provider ends. And it is not advisable to have a VPN which doesn’t have the facility of killswitch. And even if it has a kill switch, every time it doesn’t need to work.

VPN speed

One of the most crucial aspect before having VPN is speed. Never trust the velocity claimed by the provider or any test it claims to be done every VPN Banda claims to be the world’s fastest. For this again try period is significant as you can know how fast the VPN vendor is only by testing it for some time.

Can I use a free VPN? Is it secure?

If you want to use a free VPN, you must know, and you must be aware of some of the points which we have listed below. First of all, if a VPN vendor is providing free service 10, it will depend on advertising for its profit. It can be called that free VPNs are most likely to be infected with Malware.

Secondly, most of us want things which cause lest or are free of cost, and hence we ignore some of the problems or issues related to that free thing or cheap thing. Days free VPN may have embedded tracking for various purposes. It is also possible that cybercriminals order hackers or terrorists make it for trapping people.

It is also possible that the VPN main make your internet speed slow. You might notice that when you surf without VPN, you find result faster. Some of the free VPNs can also hijack your browser and direct you to some other website without your permission.

And some of these VPNs might give information about you to the government or might use this for marketing purpose too.                                                                                                                        

So, it can’t be said that a free VPN is safe and secure to use there are such VPN vendors also which will cost you and is not secure. But such VPNs which cost you and are still not secure are very few in number, almost negligible.

How are users benefited from VPN?

At a fundamental level provides privacy and security. Advantages provided by VPN.  No more geographic restrictions on websites and other information available in other areas but not in yours. There are some information or shows which are available in a particular reason and can’t be accessed by people by other regions. But with the help of VPN, as you can hide your real identity and you can look like someone belonging to that particular religion, you can have access to that information which were not accessible from your region.

Protection from snooping on untrustworthy Wi-Fi hotspots.

There are chances that through public Wi-Fi services like in restaurants or on railway stations, other users like you can get some vital information. And that provider is not secure. But if you are using a VPN, you can hide your identity and secure your data very well.

The gain of anonymity through hiding the exact location.

As the IP address can be proven to help find your location and country and ZIP CODE and beauty and doesn’t let your IP address know about your search or web history so it can make you anonymous.

Protection from being logged while torrenting.

A VPN directs connection through the servers of its own; it changes IP address and encrypts your traffic. If you are using an excellent torrenting VPN your will be made anonymous and if Noone can track you back.

VPN Prices

The least important criteria for getting a VPN provider should be the price. If a $5 per month VPN Service is not working correctly from your location to the destination server, it doesn’t matter that it is cheaper than $20 per month one.

Of course, VPN should we choose based on the performance and the testing and features provided by it.

A quality, safe VPN service will usually cost you $5-12 per month if you pay every month or as little as $30-50 per year. Will while having VPN Service you can have a significant profit if you pay for a longer duration at one time and in this way you can save some money.
