Assess The Features Of Each VPN Provider

Next, research each provider to determine what features it offers. Look for these features:

A No-Log Policy

A no-log policy states that the VPN provider wont collect, track, or log your data. Providers with this policy only store your login information and customer data , nothing about what you do online.

An Adblocker

Adblockers prevent you from seeing pop-up ads, search engine ads, and website ads as you browse the internet. Adblocking is important because cybercriminals can use ads to get you to click on compromised websites, download malware, or contact someone wholl use social engineering to scam you.

They also block tracking scripts that want to stalk your browsing habits on many sites.

Adblockers may also speed up your browsing experience. Research from Opera shows that when you dont use adblockers, websites load 51% slower than when you use adblockers. In the study, websites took an average of 3.8 seconds to load with ads and 1.89 seconds to load without ads.

A Kill Switch

A kill switch immediately cuts your internet connection if your VPN connection breaks. Without a kill switch, your data would become visible to anyone with malicious intent until you reconnected to your VPN.

This feature allows many users to use a single IP address. Using a single address may seem counterintuitive, but its pretty clever. As people use the internet simultaneously, its impossible for anyone tracking data to determine what a single user is doing online.

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.

Can I Use A VPN To Watch Netflix And Hulu

Yes. But like with most things on this list, it all comes down to the specific VPN that you use.

The problem with Netflix overall is that even though its now available in over 130 countries, not all shows are distributed equally.

Due to complicated licensing agreements that were established before Netflixs big international rollout, various TV stations retain the rights to even some of Netflixs own shows, which effectively prevents Netflix from legally making those shows available on their platform.

Complicated legal stuff, but VPNs can help here.

The way Netflix and Hulu block some of their content in parts of the globe is based on location filters. Meaning that if youre in a country thats banned, youre banned.

VPNs make this easy to fix. Since you can select the server that you want to connect with, all you need to do to unlock certain Netflix shows is connect to a server in a country where that show is available. Thats all. We have a comprehensive post on how to watch Netflix via a VPN + the best VPNs that allow you to do that.

Using VPN On Browser Extensions

NordVPN also comes as a browser extension for Google Chrome and Mozilla Firefox. Keep in mind that the extension is different from the app: it protects only your browsers traffic but not your computers traffic the way the NordVPN app does. Using a VPN extension will change your browsers IP address, but at the same time you will be able to use your real IP for other connections.

  • Add the extension to your browser of choice and sign in.
  • Click Quick connect or choose a desired country.
  • You Connect To The VPN Server

    VPNs: Your personal tunnel to privacy

    First, you turn the VPN software on through a button inside the app. The software will connect your computer to a VPN server, which will act as an intermediary between your computer and any servers you want to access.

    Many VPN providers let you select the country or city of the server so you can browse local content.

    How Does A VPN Work In 30 Seconds

    When online, youre constantly sending out data from your device, and receiving data back .

    This raw data can be seen by your Internet Service Provider , or perhaps other parties if they intercept it at some point during the journey.

    A VPN app encrypts the data as it leaves your system, sending it to one of the VPN firms servers around the globe before it heads out onto the internet. Because the data is now encoded scrambled its unintelligible and cant be exploited by ISPs or other snooping parties.

    A second benefit is that the VPN server effectively becomes the origin of your internet traffic, meaning your location appears to be where that server is based and not your actual location at home. So, you get not just security but also anonymity with a VPN .

    You Want To Stay Safe Online

    Government agencies, marketers, internet service providers would all love to track and collect your browsing history, messages, and other private data. Best way to hide it? Using a VPN to encrypt your traffic, hide your IP, and cover your tracks online. Use it at home, at work, and on the go to enjoy non-stop protection.

    Can You Be Tracked With A VPN

    Dont think that VPN single-handedly solves all your privacy problems. If youre logged in to your Google account oryoure logging into various services with your Facebook login, VPN cant help you. Google and Facebook will knowexactly which sites youve visited.

    Additionally, the modern internet is rife with browser-based tracking technologies cookies fingerprinting scripts,and other nefarious stuff. These can still threaten your anonymity even if your VPN is on.

    To limit the risk, you should stay away from social media accounts when using a VPN. Also, youshould use addons that block intrusive tracking scripts. uBlock Origin, Ghostery, and NoScript are just a few suchtools.

    How Does A Virtual Private Network Work

    Virtual private networks are used to setup a direct connection between your computer and the office by way of a private tunnel over the internet.

    Normally, when you send information over the internet, it is sent as a piece of data called a packet. Often, packets are in plain text and can be easily read by anyone or scanned by Big Data. Packets also carry your IP address.

    With a virtual private network, your packet is encapsulated inside of another packet to protect what you are transmitting. In this way, your sensitive information is better protected than if sent via email or open internet.

    And using a VPN is easy. Logging in to your VPN is like just logging into a computer with a username and password. Only those with the correct login credentials can access the VPN. Just like a standard computer user profile or account, we can setup a VPN to only be accessible with certain permissions and restrictions.

    Secure Connection For Remote Work

    Businesses today need to consider internet safety more than ever. With more people than ever working from home, sensitive company and customer information is at a higher risk of theft.

    For example, say an employee connects to a work computer remotely on a public network without using a VPN. Theoretically, anyone on that public network could gain access to the internal company network, because the employee did nothing to hide their information.

    Unfettered access to company files and customer information can be catastrophic to a business. Using a VPN to connect to business-based networks can help ensure that sensitive data is hidden behind the dummy information provided via the VPN.

    How Does a VPN Work?

    We have created a series of pictures that show how a request from a client computer in the subsidiary office reaches an application server at the headquarter office, and how a response gets sent back. Each step of the process is shown clearly with highlighted lines and relevant network information. Simply go through the images to see a step by step progression. It’s worth noting that this type of setup still allows other VPN clients to log on to the OpenVPN Access Server and gain access to any of the devices in these 2 networks. Also, a site-to-site setup need not be limited to one subsidiary network, it can be multiple just as easily.

    How To Set Up The Openvpn Linux Gateway Client

    We prefer using a Linux operating system to handle the role of a VPN client that also serves as gateway. We prefer Ubuntu LTS on a virtual machine or dedicated hardware. We simply have the best experiences with it, and there are simple tools available on Linux that are free and easy to install and use to diagnose any problems that may come up. Also Linux is free to use and can run on very light-weight equipment. Even a Raspberry Pi3 or such can handle this task, and there are also embedded systems that can handle it. Equipment aside, if you have a Linux operating system with an OpenVPN client that can connect to the OpenVPN Access Server, and you can enable something called IP forwarding, then you should be able to get an OpenVPN Linux Gateway client up and running fairly easily. You do not need the install the OpenVPN Access Server program itself on this Linux client system.

    What you do need is the OpenVPN open source client program for Linux. On Ubuntu you can install this with the command apt-get install openvpn. With the client program now installed, it is going to check for any *.conf files in the /etc/openvpn/ directory and at system startup try to connect them and keep them connected. What we need next is to obtain the auto-login connection profile for the user account created for site-to-site connectivity, and save it in the /etc/openvpn/ directory. To do that we need to get the file first:

    Layer 2 Tunneling Protocol

    This protocol combines PPTP with the Layer 2 Forwarding tunneling protocol. It strengthens the data tunnel provided by PPTP but does not provide users with encryption or privacy capabilities. As a result, the protocol is typically bundled with a security protocol such as Internet Protocol security .

    What Does A VPN Server Do

    VPN servers are at the heart of any VPN service they forward your internet traffic to the destinationserver and return the response to you

    The top providers have hundreds or even thousands of servers scattered across the globe. This is important not onlyto ensure good performance but also because choosing the VPN servers country amounts to choosing your virtuallocation. The websites you connect to will assume youre based in the VPN servers country.

    If youre not connecting through a VPN server, the owner of any website you visit will knowyour IP address. You may want to avoid this due to 2 basic reasons:

    • Privacy
    • Access. You will get different versions of websites based on your location. In some cases, thismight mean worse prices for the same goods in others, it may mean different content or no access at all.

    Depending on the provider may collect data about you, such as your IP address, session time, the websites youre visiting, etc. This is something to avoid, which is why its crucial to choose a VPN service with a no-logging policy. Some providers even go so far as to use diskless, RAM-only servers, which are technologically incapable of storing lots of data.

    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 to ensure both the concealment of your internet activities and ensure the highest level of security.

    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.

    How A VPN Works For Dummies

    In the event that you use a proxy server, it facilitates access to the internet on your device. When you connect to a VPN, everything that comes with a proxy server is combined with securing your data between your phone and the internet, in so far as you cant have your information harvested and stolen for the purpose of going online.

    Choosing A VPN Service That Fits Your Needs


    So now that you understand the basics of what VPN is and how it works, you may be considering using one yourself. In lieu of endorsing any particular company’s services, I’ll give you some tips on how to choose a good VPN service.

    The physical location of the VPN service should be considered. If you want to bypass region-based content blocking, you will want the VPN to be operating in the country that you want to appear to be in from the perspective of the company that’s delivering your media. For example, a lot of people here in Canada use American VPNs so that they can access the content that Netflix only makes available to the American market. You may also want to consider the laws of the jurisdiction of where your VPN is physically located. For example, American VPNs may be subject to search warrants from American law enforcement agencies.

    Consider what sort of devices you’ll be using with your VPN. Are you only going to use the VPN with your PC? Or do you also want to be able to use the VPN on your smartphone or tablet? Which operating systems do you use? Some VPN providers offer dedicated mobile apps, and some VPN providers require software that’s only compatible with certain operating systems.

    All data in transit should be encrypted these days. VPNs are a feasible way to help protect data from man-in-the-middle attacks.
