What Is A VPN | How Does It Work ?

One benefit of a VPN is its data encryption features. Encryption, or putting data into a coded format so its meaning is obscured, allows you to keep confidential information safe.

If you are an individual thinking about investing in a VPN for your company, one benefit is that workers can connect to your office network and look at sensitive materials on their own devices while away from the office. As remote work seems a possibility even after the pandemic ends, a VPN is a helpful investment to keep confidential material safe off-site.

How Secure Is A VPN

VPN security causes debate among IT pros and others in the industry, and no two services are identical in their offerings or security. There are two main factors:

  • The limitations of the type of VPN technology used by a provider.
  • Legal and policy limitations affecting what can be done with that technology. The laws of the country where the server and the company providing the VPN are located and the companys own policies affect how the company implements this technology in their service.

Lets take a closer look at these factors.

VPN Protocols

VPN protocols define how the service handles data transmission over a VPN. The most common protocols are PPTP, L2TP, SSTP, IKEV2, and OpenVPN. Heres a brief overview:

Generally speaking, most VPNs allow you to select the protocol you use. The more secure protocol you connect through , the more secure your whole session will be.

Unfortunately, not all devices will allow you to use all these protocols. Since most of them were built by Microsoft, youll be able to use them on all Windows PCs. For Apple devices, you will come across some limitations. For example, L2TP/IPsec is the default protocol for iPhone. And Android well, Android has some problems of its own, which well get to later on.

Encryption Basics

In brief, encryption works by:

  • Starting with plain data
  • Applying a key to transform the data
  • Ending with encrypted data
  • The encrypted data is only readable by someone with the original key used to encrypt the data.

    Virtual Private Network Explained

    Virtual Private Networks is a network of servers that help users maintain their privacy and security online. Typically, robust communication protocols and encryption are used to connect between servers and its users.

    VPN in deconstructed terms can be seen as:

    • Virtual Connections created exist only in cyberspace.
    • Private Servers involved are all private and not open to everyone.
    • Network Various devices are being linked together.

    Can I Use A VPN For Torrenting

    In general, yes, but that depends on the specific service youre using and also the kind of things that you are torrenting.

    Torrenting is a common name for a specific protocol used to transfer data and files over the web, but not the actual types of files. Although it gets a lot of bad press overall, it is perfectly okay and legal if youre transferring files that you have the rights to. Piracy, on the other hand, is completely illegal regardless of the tools that you use to do it.

    Then, theres the VPNs own policy regarding torrenting and how its handled. Most of the quality VPN solutions in the market will allow torrenting. According to our research, you can torrent with all popular VPNs NordVPN, ExpressVPN, Surfshark, VyprVPN and PIA.

    When it comes to the security aspect of torrenting, it all comes down to the VPNs policies regarding things like logging or sharing your user data. In general, if a VPN doesnt keep logs overall they also dont keep them for your torrent activity.

    Another aspect worth considering when choosing a VPN for torrenting is the download speeds that the service can offer. Of course, this sort of information can be hard to come by most of the time you only find out after you buy the VPN. We did some testing of our own and based on it, we can recommend these VPNs for their good download speeds: NordVPN, ExpressVPN, VyprVPN, and PIA.

    What Should You Look For In VPN Services

    What is a VPN and how does it actually work?

    The VPN market is crowded with options, so its important to consider your needs when youre shopping for a VPN.

    Think about what is important to you. Do you want to be able to surf the web anonymously by masking your IP address? Are you afraid that your information could be stolen on public Wi-Fi? Are you a frequent traveler who wants to be able to watch your favorite shows while youre on the go.

    A good VPN can help you check all three boxes, but here are some other points to consider.

    VPN Uses: Keep Your Online Chats Private

    While there are a number of secure messaging apps available , many popular apps don’t offer encryption, or require you to opt-in rather than opt-out. If your messaging isn’t encrypted there’s a chance it could be intercepted by an outsider.

    Also, while it won’t affect your regular cell signal, a VPN can help protect your VoIP calls. And, even if your service provides encryption as standard, using a VPN as an extra layer of protection will give you the reassurance that you really can speak your mind.

    In A Nutshell How Does A VPN Work

    In short, a VPN redirects your traffic away from your ISP’s servers and send it through its own. While doing that, it encrypts it so no one else can read it, even it were to be intercepted.

    VPNs use a number of different protocols to transfer your data, with OpenVPN and WireGuard now considered the most popular and secure.

    While VPNs function well to protect your data, many use them to unblock streaming content from overseas. That’s possible thanks to global networks of servers owned by a particular service, and by routing through a server in a different area, you can trick sites into thinking that you’re really there.

    Overall, VPNs are extremely handy applications and provide lots of different functions. Now that you know more about how they work, you should be in a better position to choose a VPN provider that suits all your needs.

    Free VPN Versus Paid VPN

    Running a good VPN service costs serious money robust servers, data transfer, infrastructure, employees, and so on. If the service is offered for free, consider what compromises may have been made. Are they logging activity for their own reasons? Are they displaying their own ads? Is your data being sold to a third party?

    Paying for a VPN isnt a huge investment. Weve tested some great solutions for as little as $3-5 per month, which doesnt seem a lot in exchange for peace of mind and improved online privacy.

    How Much Does a VPN Cost?

    The average out of 70 popular VPNs is $4.99 a month, which tells you a lot about what sort of an expense this usually is. VPNs that cost more than $10 are uncommon, and theres not a lot of reason to buy them since there are more affordable solutions out there.

    Most services give out big discounts if youre willing to subscribe for two to three years up front, instead of renewing your subscription monthly. For example, NordVPN a VPN that we very much enjoy costs $11.95 if paid monthly, but you can grab their 3-year plan for just $3.49/month .

    VPNs And Their Current Use

    Do VPNs Really Make You Anonymous?

    According to the GlobalWebIndex, the number of VPN users worldwide increased more than fourfold between 2016 and 2018. In countries such as Thailand, Indonesia and China, where internet use is restricted and censored, one in fiveinternet users uses a VPN. In the USA, Great Britain and 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, video 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 to be surfing from another country, enabling you to access this content from anywhere.

    VPN Uses: Protect Your Identity

    When most people think of a VPN, they think of a privacy solution first and foremost and with good reason. The original primary VPN use is to protect the user and their data, ensuring safe internet use whatever the activity.

    A core element of a VPN is tough encryption usually AES-256 combined with a secure protocol and this means every last bit of traffic sent through the VPN is unreadable by anyone who intercepts it. That interceptor might simply be your ISP trying to log or limit what you use their connection for, or it could be a malicious individual or program looking to steal your data.

    Who or whatever they are, VPNs avoid them by using a ‘tunnel’ that starts at your device and ends at your destination be that Netflix, a geo-blocked social network or your online banking.

    In between your device and your destination is where your data is at risk, so a VPN eliminates that by both encrypting your data and routing your connection through one of its own servers, masking your IP address and any other identifying information. If you’ve chosen a quality, zero-logging provider, you should be able to trust your VPN’s servers more than your ISP’s.

    In essence, a VPN removes or encrypts any information that could link you or your device to your activity on the web. It’s a one-stop shop for taking back personal privacy online.

    What Are The Disadvantages Of VPN

    What is VPN and How Does it Work?

    The first obvious downside of using a VPN is that it could slow down the performance of your internet connection. That’s particularly the case when using servers in far-flung countries, as the distance of the server matters.

    While that might sound drastic, the reality is that in most cases, any performance impact will probably not be that noticeable certainly with the top VPNs which we fully test for performance in our reviews. Even with a more average VPN in speed terms, with some careful choice of servers, you probably wont notice much, if any, difference in everyday computing either. The main scenario where you might want to switch off a VPN is online gaming, an area thats very sensitive in terms of latency. Although gaming VPNs certainly have their uses, too!

    Another potential thorny area is that while using a VPN means your ISP can no longer snoop on your data, instead that data is going through the VPN providers system, and an unscrupulous VPN could play fast and loose with your data. Every VPN will insist that it maintains your privacy, though , and claim not to keep any logs. They’re small bits of logged data relating to the service, which can but hopefully shouldnt include how you use it.

    In short, most of the potential disadvantages of adopting a VPN can be neatly swerved around by choosing a highly-rated and trusted provider.

    Can I Still Be Tracked Online When Using A VPN

    If you pay for your VPN with a credit card, your VPN provider will likely know who you are. Since youre connecting to your VPN from your device, theyll also have your IP address. But thats it most VPNs dont monitor your online activity, and many include explicit no-logging policies that prevent them from collecting any information about what you do while using their services.

    A VPN protects your data along its trip between your device and the VPN server. If youre connecting to websites that use HTTPS encryption, your data will be safe along its entire journey. But if youre connecting to unsecured websites, your data will be exposed after it leaves the VPN server.

    While VPNs can prevent people from tracking you based on your IP address, they cant block other web tracking methods such as cookies and browser fingerprinting. And once you log in to a site, such as a social network, that site can still track what you click on, share, and like even if youre using a VPN because youre logged in.

    Security and privacy extensions for Chrome and, especially, truly secure and private browsers can block cookies and protect you against browser-based web and ad tracking, while a VPN insulates your data and hides your IP address.

    VPNs that offer give you another layer of protection. By grouping multiple users under a single IP address, these VPNs make it very difficult for anyone to pinpoint the actions of any specific user.

    VPN Uses: Access Free Voip Services Like Whatsapp

    Strict national governments with huge stakes in mobile networks will often restrict access to free VoIP services like WhatsApp, Skype, Messenger and more because doing so ensures they make more money.

    This is a huge reason why you might want a UAE VPN when living or traveling to Dubai or elsewhere, and while rules change frequently, it’s been known for UAE residents to have to use a VPN to even access voice chat on video games.

    Paying for a VPN and using free VoIP services usually ends up costing much less than spending money on the monopolized telephone networks. For those who are short on money, a cheap service like Surfshark less than $2.50 a month is a great way of saving cash and staying in contact with loved ones.

    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.

    What Is VPN How It Works Types Of VPN

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

    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 method 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 from the ICSI Networking and Security Group found that 38% of the 283 Android VPNs 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.
