How Does A VPN Work In Practice
A VPN masks a users true location to the one they set their VPN to. This enables them to access content or websites typically restricted to that region. For example, a user in the U.S. can set their location to the United Kingdom and watch content from streaming websites aimed at British audiences. A U.S. citizen can also continue streaming their favorite shows even when they are away from the country on holiday.
Let us take a look at some of the common uses of VPNs.
Protecting Browsing History
A VPN enables users to keep search informationsuch as medical conditions, required surgery or treatment, travel plans, or even gift idea researchprivate and prevents their ISP and web browser from serving related ads.
Securing IP Address and Location Data
An IP address is the internets equivalent of the return address on a handwritten letter. Therefore, anyone that knows a users IP address can access the information they have searched for on the internet and where they were when they searched for it. Furthermore, a users search history can be viewed if they connect to a web browser on a public or work computer.
VPNs use IP addresses that do not belong to a user, which enables them to connect to and browse the web anonymously while maintaining their privacy online. Using a VPN also enables users to prevent their search history data from being collected, viewed, and sold.
Hiding Streaming Location
Ensuring Internet Freedom
When Should I Use A VPN
For the best security, you should use a VPN as often as possible, whether you’re using public Wi-Fi or working from homeall the time, ideally. But that’s an aspirational goal, and it’s not always achievable. If your VPN is causing problems and you need to switch if off, don’t beat yourself up. At minimum, you should use a VPN whenever you’re using a network you don’t control, and especially if it’s a public Wi-Fi network.
VPNs for Android and iPhones are a little trickier, particularly if you frequently move in and out of cellphone coverage. Each time you lose and regain data connectivity, the VPN has to reconnect, which adds a frustrating wait. It’s also just less likely that your cell traffic can be intercepted by bad guys, but we’ve seen researchers prove that it can be done.
Most mobile devices can automatically connect to any familiar looking Wi-Fi network. That’s out of convenience to you, but it’s trivially simple to impersonate a Wi-Fi network. Your phone may be connecting to a digital honeypot without you even realizing it. At minimum, you should use a VPN when connecting via Wi-Fi to keep your data safe, even if your device falls for an attack like this one.

How Can A VPN Help Protect Against Identity Theft
Identity theft occurs when thieves steal your personal information and use it to commit crimes in your name like taking over or opening new accounts, filing tax returns in your name, or renting or buying property. A VPN can help protect against identity theft by helping protect your data. It creates an encrypted tunnel for the data you send and receive thats out of reach of cyberthieves.
If your smartphone’s Wi-Fi is enabled at all times, your device could be vulnerable without you ever knowing it. Everyday activities like online shopping, banking and browsing can expose your information, making you vulnerable to cybercrime.
A VPN can protect the information you share or access using your devices. Thats especially important when using a public Wi-Fi network, where a cyberthief on the same network could capture your login credentials and the credit card number you type in when you shop online.
You cant prevent identity theft. No one can. Some security aspects like a data breach at an organization where you have an account are out of your control. But a VPN can help safeguard the information you send from and receive on your devices.
Enable The Kill Switch
Many VPN services have a kill switch that will stop any data being sent over the internet connection if the VPN connection drops unexpectedly. This helps to protect your privacy by ensuring your real location is never leaked.
Often you have to go into your VPN apps settings to enable the kill switch, as its not turned on by default. A kill switch may not be available in all the apps a VPN provider offers. Some, such as NordVPNs iOS app, dont show a kill switch option because its permanently enabled and you cant turn it off.
Theres a good reason why kill switches arent on by default, though: you wont be able to access the internet unless the VPN is connected.
If available, you might prefer to use the App Kill Switch option which Nord offers in its Windows app. This lets you pick which apps should have their internet connections cut off if the VPN stops working, and leaves all others working as normal.
A similar feature called split-tunneling lets you choose which apps use the VPN connection and all others use the normal connection.
There are other options, but thats really all you need to do to: using a VPN is very easy.
The only other tweak you might want to make is to get the VPN to connect automatically if your device connects to an unknown Wi-Fi network. This ensures you dont forget to enable the protection a VPN offers.

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.

Data Privacy From Your Government
While many ISPs, apps and internet data hubs suggest they dont sell your browsing data to governments, the information nonetheless finds its ways into their handseven in the U.S.
Since 2013, when Edward Snowden first revealed that Verizon had been selling users internet and phone data to the NSA, Americans have become more aware of the different ways the government surveils and collects their data. Following the Snowden leaks, and subsequent outrage, several laws were enacted to curb government surveillance.
However, as recently as January of this year, the Defense Intelligence Agency bypassed a law demanding that government agencies produce warrants before compelling phone companies for their user data by paying third-party data brokers for that same data, according to the New York Times.
If you have qualms about governmental overreach, a VPN is a good investment in protecting your data.

How To Understand VPN Protocols
Traditionally, there are five VPN protocols. Here’s more about each protocol:
- OpenVPN is an open-source protocol. This makes it easier to adapt to a wide range of configurations and purposes. It is not the fastest connection, but it is one of the most versatile, especially when incorporating third-party resources.
- L2TP/IPSec is the most common VPN protocol of all. It is an older protocol but still plenty secure and is ideal for creating specific secure tunnels. It is fairly fast, universally applicable and has no documented vulnerabilities.
- PPTP is another widely used protocol. It was designed for dial-up networks. There are, unfortunately, a number of known security flaws with PPTP.
- SSTP is also known as secure socket tunneling. It was designed for Windows and is not widely used because of its restricted design. Despite that, it ranks competitively in terms of security and speed.
- IKEv2 is designed for mobile devices. Technically speaking, it is not a VPN, but it serves a similar role in mobile spaces.

Double Check Your Internet Connection
If none of the above steps have helped improve your VPN connection speed, then maybe the problem is with your internet connection itself. Even a premium VPN cant give you high speeds on a slow internet connection.
You can ascertain whether the problem lies with your internet connection by running a speed test. If the speeds are below what you usually get or what your ISP has promised, then its a clear sign that your network connection is performing sub-optimally.
Rebooting your router can sometimes resolve underlying connectivity issues and get your speed back up. But if the problem persists, then you may need to take it up with your ISP or switch to an internet plan with higher bandwidth.

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.
Setting Up And Using The VPN

Once you dont need to be connected to a VPN anymore, click the Disconnect button and your connection will be back to normal.
In case you want to tweak a feature or two , youll need to open the Settings menu. There, youll be able to see all the extra features offered by your VPN.
It’s always a good idea to enable a kill switch. That way, your Internet will be shut down each time the connection to a VPN server drops. This can protect your online safety from accidental IP address leaks.

Data Privacy From Your Internet Service Provider
While connected to your home Wi-Fi, you are less likely to be attacked by strangers than on a public connection. However, your data is still vulnerable.
Your ISP or internet service providerComcast, Spectrum, Verizon or other company who you pay for Wi-Fi each monthcan access all your internet data. Your ISP can see when, where and how you browse.

What Are The Downsides Of Setting Up Your VPN Server
Like in every method, creating and using your VPN server has several disadvantages.
- If you lack the necessary technical and networking knowledge, this can be a difficult task.
- If you miss out on any essential security setting, your devices can be vulnerable to cyber threats.
- If you do not upgrade your system with the latest security patches, ideally, your VPN connection is not as secure as most commercial VPNs that automatically update.
- Your home network can have slower upload and download speeds. Therefore, the VPN connection can become slower.
- You cannot guarantee that your ISP is not spying on you since there is only encrypted traffic between the VPN server and the client.
