What Is A VPN In Simple Terms

What is a VPN and how it works | NordVPN

A virtual private network, better known as a VPN, protects your identity and browsing activity from hackers, businesses, government agencies, and other snoops. When connecting to the internet, your data and IP address are hidden by a type of virtual tunnel. This keeps others from spying on your online activity.

Does The VPN Have A Kill Switch

What if your connection with your VPN provider drops? Usually, your laptop, smartphone or other device will revert back to public Internet Protocol address provided by your home Internet Service Provider. This means that snoops could then be able to track your online activity and see your IP address until you connect back with your VPN provider.

Some VPN providers offer a kill switch feature to deal with this. If the VPN connection drops, the kill switch is designed to instantly sever your connection to the internet. This way, your IP address and online activity arent visible to anyone else.

How Does VPN Encryption Work

Encryption is persistent when you establish a connection to a VPN server. Your data between your device and the VPNserver is encrypted. Its deciphered only at the endpoints: when the data reaches your device and leaves aVPN server.

VPNs use three types of cryptography: symmetric encryption, asymmetric encryption, and hashing.Heres how VPN encryption works:

  • When you connect to a VPN server, the connection performs a handshake between a VPN client and a VPN server.During this step, hashing is used to authenticate that the user is interacting with a real VPNserver, and asymmetric encryption is used to exchange symmetric encryption keys.A few popularexamples of asymmetric protocols used at this stage are RSA or Diffie-Hellman.
  • Once the handshake is successful, symmetric encryption is used to encrypt all data passingbetween the user and the VPN server. The most common symmetric encryption cipher used by VPNs is AES.
  • Since AES is the most popular data encryption cipher used by VPNs, lets take a look at this cipher in more detail.

    How Does A VPN Work For Torrenting

    This is a thornier issue, because some VPNs dont work for torrenting at all. Some VPNs dont support torrent users, and others may only support such P2P file-sharing on certain VPN servers .

    This could be for bandwidth reasons , or legal reasons .

    So, the initial consideration if you want a VPN for torrenting is to pick a provider which supports them and weve rounded up the best torrenting VPNs here for your convenience.

    As to how the process actually works when torrenting, its the same as a VPN normally functions, the key parts here being that your IP address will be hidden, so actions cant be traced back to you, and your traffic is encrypted, meaning no one can see what youre up to online or downloading.

    That all said, using a VPN doesn’t make downloading pirated films, music and files any more legal. And it’s not something we condone at TechRadar at all.

    You Can Save Money With A VPN

    Here’s where VPN use gets a bit more niche. Protecting privacy and accessing blocked content are both quite popular, but did you know that you can also save money on flights and hotels with a VPN? It’s all in the geographic location!

    Airlines use dynamic pricing, which means they increase and decrease airfares depending upon the country you are visiting from, said Rameez Usmani, Digital Marketing Executive at PureVPN, in an interview with Tech.co. With a VPN, you can find cheap flights by changing your current location to a virtual server in another country.

    How cool is that? VPNMentor even did a comparison between flights found through a USA server and an Indian server, and the prices are clearly different, as you’ll see below. Granted, the difference isn’t substantial, but when it comes to traveling, saving every bit of money counts.

    An even better way to save money with a VPN is to utilize a free one. Unlike many other similar services, the VPN market is filled with completely free options that can give you the basic protections and features of many of the paid models. However, as is typically the case with free services, there’s a catch.

    Both Android and iOS come with basic VPN capabilities to allow you to connect to your corporate networks securely. Your IT organization will generally advise you when you should use this feature, but as we’ve discussed, when away from your home or office, and especially if you’re using an open, public Wi-Fi connection, you should.

    If you’re connecting to web applications like email or Facebook, you should consider using a VPN service — particularly if you’re connecting via an open Wi-Fi network. Most good VPN services offer both iOS and Android clients.

    Is A VPN Legal

    VPNs are not illegal in the United States. However, not all countries have the same laws regarding these services. For instance, China, Russia, and North Korea either regulate or ban VPNs. You should know, too, that if you commit an illegal act online using a a VPN, that act is still illegal. Customers often use VPNs so that they can stream sporting events and TV shows that they may be blocked from accessing in their own region. Using a VPN to pretend that you are logging onto the internet from a different location might violate the service agreements of streaming services.

    A Quick Overview Of The Whole Process

    What is a VPN? How Does it Work? An Easy Explanation
  • You use the VPN client to connect to a VPN server. When you do that, the client starts encrypting your data.
  • The VPN client establishes a connection to the appropriate server through your ISP, and sets up the VPN tunnel.
  • The VPN server replaces your IP address with its own , starts decrypting the data it receives from you, and forwards your connections to the web.
  • Once the VPN server receives the online data you requested from various web servers, it encrypts it, and sends it back to your device through your ISP.
  • When the VPN client receives the incoming traffic, it decrypts it for you.
  • Because an encrypted tunnel is established between you and the VPN server, your ISP cant monitor your online traffic and data. Only the devices on each end of the VPN tunnel can decrypt the information since only they can encrypt it. Also, the VPN server will replace your IP address with its own as well once the connection is established, effectively hiding your geo-location online.

    All in all, unlike accessing the web without a VPN, doing it with a VPN ensures you get to enjoy private browsing, peace of mind knowing your personal info is protected, and unrestricted access to any content .

    And thats pretty much how VPNs help in private browsing and how they work. While the whole process might seem like itd take a long time, it usually happens almost instantaneously.

    Can A VPN Protect My Search History

    A VPN protects your search history through the secure connection you share. When you search for a website, or type a URL into your navigation bar, your device sends something called a DNS request, which translates the website into the IP address of the web server this is how your browser can find the website and serve its content to you. By encrypting your DNS requests, a VPN can hide your search habits and history from those that might use that info as part of building a profile of you. This type of info could be used in a wide variety of ways, from legitimately serving targeted ads to nefarious social engineering.

    Key Considerations Before Choosing A VPN

    Hopefully, you now have a better idea of how a VPN works. Before we send you on your merry way, heres a checklist of things to look out for before you choose a VPN:

    • Is it free or paid? – When it comes to a secure, speedy service, it really is worth it to pay for a VPN. Many free VPNs tend to offer only the PPTP protocol which, as we said earlier, really isnt very effective these days. They have fewer server locations and less bandwidth to offer. Very often with these free options your data is tracked and sold to third-party businesses. Paid VPN options more often than not have more powerful security protocols on offer than their free counterparts. A good paid VPN should have more server locations and more bandwidth, providing you with a faster service. They will also have customer support on hand if you run into any issues.
    • Are VPNs legal in your jurisdiction?
    • Where is the VPN server located?
    • Does the company log your activity?
    • Does it protect your whole device or is it just an add-on?
    • What are the protocols of the VPNs encryption mechanism?
    • The number of servers and amount of bandwidth a VPN service has if both are low it could make for a very slow web-surfing experience.

    Reasons Why Free VPNs Are Not Safe

    “Is VPN safe?” is a question everyone should be asking, and the answer is straightforward. Using free software is not an effective solution for ensuring VPN security because it often will not protect data and browsing activity on the internet. Key reasons not to use a free VPN include:

  • Free VPN tools compromise user security: Many free VPN tools contain malware that could be used by cyber criminals to steal users data, gain unauthorized access to their data or machine, or launch a cyberattack. Research report from the ICSI Networking and Security Group found that 38% of the 283 Android VPN apps studied contained some form of malware presence. Therefore, a VPN application may not always be safe when using free tools.
  • Free VPN tools track online activity: A secure VPN should protect a users activity while they browse the internet, but some free VPNs do the opposite by tracking users online activity. The same ICSI research found that 72% of the free VPN services analyzed embedded third-party tracking tools in their software. This enables VPN tools to collect user information and sell it for a profit to the highest bidders, which allows advertisers to target free VPN users with ads. Some free VPN tools hide information about whether they share or sell user data, but others say so in their privacy policies.
