  • It hides your activity from anyone who might be interested in it.
  • It hides your location, enabling you to access geo-blocked content .
  • Makes you more anonymous on the web.
  • Helps you keep the connection protected when using a public WiFi hotspot.

Overall, use a VPN if your web privacy, security, and anonymity are important to you. Roughly $3-5 a month is a small price to pay for all of that.

Advantage : Prevent A Digital File

Advertising networks such as Facebook, Google, and Twitter are constantly collecting information about you through your online traffic. With this information, they can show you tailored ads but more importantly, they are free to sell this information to a third party. By encrypting your data using a VPN these networks will have a harder time collecting information on you. They will also have less influence on what you see online

Is A VPN Safe

You may wonder how safe you are with a VPN provider. Your internet traffic is redirected and runs through the servers of the VPN provider. The provider can see everything you do if it would want to. Therefore, its important that you have confidence in your VPN service. Most VPN services do not log what you do and wont store your data.

However, there are VPN services that abuse the data that travels through their servers and sell your data to advertisers, for example. This is especially the case with free VPNs. These are often not safe. Before using a VPN, it is therefore important that you do research in advance. Well give you a few recommendations for good and secure VPN services later in this article.

How Does VPN Work

Public WiFi: The Dangers That Lurk & The Tips & Tools That ...

Let’s start with the basic idea of internet communication. Suppose you’re at your desk and you want to access a website like ZDNet. To do this, your computer initiates a request by sending some packets. If you’re in an office, those packets often travel through switches and routers on your LAN before they are transferred to the public internet through a router.

Once on the public internet, those packets travel through a bunch of computers. A separate request is made to a series of name servers to translate the DNS name to an IP address. That information is sent back to your browser, which then sends the request again through many computers on the public internet. Eventually, it reaches the ZDNet infrastructure, which also routes those packets, grabs a web page , and sends all that back to you.

Each internet request usually results in a whole series of communication events between multiple points. The way a VPN works is by encrypting those packets at the originating point, often hiding the data and the information about your originating IP address. The VPN software on your end then sends those packets to the VPN server at some destination point, decrypting that information.

One of the most important issues in understanding the limits of VPNs is understanding where the endpoint of the VPN server resides. We’ll talk about that next.

A VPN Is Used Primarily For What Purpose

Youve probably heard that VPNs are used to;boost your privacy and security online. That still holds true, even though VPNs have evolved to offer a broad spectrum of features. Its always wise to go back to basics, especially when it comes to highly sophisticated technologies, like those making VPNs possible. So, the big question is a VPN is used primarily for what purpose?

Well, there are many ways to answer that question. However, it all comes down to three core things. Even today, a VPN is used primarily to hide your Internet browsing activity, access geo-blocked websites, and bypass Internet censorship. With that said, lets take a closer look.

Is There A Mobile VPN App

A VPN thats usable only on your computer isnt going to do you much good if, like many people, you spend a lot of time on your phone. According to a study by online marketing agency Semrush, 66% of website traffic in 2020 came from mobile devices. If your browsing habits are similar, you need a VPN with a mobile app.

All the VPN providers featured here offer Android and iOS mobile apps. Some also support smart devices AVG Secure VPN can be used on your Android TV. Do the following VPNs offer a mobile app?

The Advantages Of VPN

Consumer VPNs have a huge amount of advantages. You’ll be able to access sites like torrent repositories that may be blocked by your ISP. If you’re in a country like China or the UAE, you’ll be able to sidestep government restrictions. You’ll be able to watch shows on Netflix that aren’t available in your country, and even access country-specific services you pay for like Hulu and HBO Max if you’re out of your home country.

What’s more, if you take the right precautions alongside using the VPN , you can also avoid linking yourself to any activity you’d prefer to keep totally private.

The Disadvantages Of VPN

What is VPN? Benefits of VPN? How to use VPN?

It’s well-known that many VPNs do have an impact on performance. That’s almost inevitable thanks to the fact that you’re essentially making your connection travel further. However, if you pick a fast VPN you won’t notice much of a difference at all.

If you choose to try out a free VPN, you’ll also be subjected to certain limitations. For example, you may have a data limit, and almost invariably you won’t be able to access streaming site â plus, free services often aren’t as secure as paid ones.

It’s also worth noting that on rare occasions you may be faced with CAPTCHA tests on some sites when using a VPN. This is because a VPN’s IP addresses are shared between users, and some sites may detect ‘unusual’ activity. In our experience, however, this is fairly unobtrusive and is preferable to the unprotected alternative.

Finally, it’s essential you make sure to sign up for a reputable VPN provider â taking your pick from any of our guides is a good place to start. If you choose to go with a lesser service you may be putting yourself in danger of having your data stolen and leaked.

When Should I Use A VPN

Should I trust this VPN provider? More often than not, you can’t and shouldn’t.

We’ve already discussed the use of a VPN when connecting offices. Any time you have two LANs that need to link over the public internet, you should consider using VPN technology or an;equivalent method of enterprise protection. In this case, the VPN software will probably run in a router, a server, or a dedicated VPN server hardware appliance.

We talked about two use cases above for consumer VPN services: Protecting your data and spoofing your location. We’ll talk more about location spoofing later, so let’s focus on data protection for now.

When you’re away from home or the office, and you connect to the internet, you’ll most often be doing so via Wi-Fi provided by your hotel or the restaurant, library, or coffee shop you’re working out of at that moment. Sometimes, Wi-Fi has a password. Other times, it will be completely open. In either case, you have no idea who else is accessing that network. Therefore, you have no idea who might be snooping on your internet traffic, browsing history or online activity.

And then, of course, there are those people in restrictive countries who need to hide their activity merely to gain access to the internet without potentially grave penalties.

The Predecessors Of The VPN

Their efforts led to the creation of ARPANET , a packet switching network, which in turn led to the development of the Transfer Control Protocol/Internet Protocol .

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 and this is where the risk of exposure became clear. In 1993, a team from Columbia University and 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 and encrypts information packets shared online. In 1996, a Microsoft employee named Gurdeep Singh-Pall created a Peer-to-Peer Tunneling Protocol .

What Does It Mean When A VPN Service Talks About Server Switching

What is a VPN?

As we mentioned in the previous section, you’re usually assigned a dynamic IP address from a pool of addresses when you connect to a VPN service. But where are those addresses located? They’re attached to servers located, usually, throughout the world.

Most VPN services allow you to connect to server locations in many different countries. In our VPN directory,;we list both the number of servers the service maintains and the number of countries. By default, you’ll usually be assigned a server located in your home country. Still, if you want to obfuscate your location, you may want to connect to a server located in a different country.

Server switching is a feature — offered by most VPN service providers — that allows you to change what region or country you’re going to connect to. Most providers allow you to switch as often as you’d like . This may be useful if you’re trying to hide your location or if you’re running into some communications glitches on the server you’re currently using…

How Does The Encryption Tunnel Work

Encryption is a method of changing normal text into an unreadable jumble of code. A key, or , unscrambles the text and renders it back into readable information. When you use a VPN, only your device and the VPN provider contain the decryption key. Anyone else trying to spy on you would only see a mess of characters.

There are three main types of encryption: hashing, symmetric cryptography, and asymmetric cryptography. Each type has its own nuanced strengths and weaknesses, but they all succeed in scrambling your data so that it is useless in anyone elses hands.

Different VPN providers offer varying degrees of encryption strength. Avast SecureLine VPN uses a combination of hashing, symmetric cryptography, and asymmetric cryptography for 256-bit AES encryption the same standard that banks and the military rely on.

Avast offers an extra layer of protection with our own DNS resolution system. The DNS is what translates numerical IP addresses into their more memorable text-based URLs. The DNS is what allows you to type in a site name like rather than a long string of numbers. Cybercriminals can monitor DNS requests to track your movements online, but a VPNs DNS resolution system is designed to thwart them with further encryption. We make sure all IPv4 traffic coming from your device is firewalled and also disable IPv6 requests.
