How Do VPNs Work
VPNs work by connecting the user to a private server as opposed to a public server. The private server encrypts the users web traffic and activity in a tunnel and replaces their IP address, which makes them much less likely to be hacked while on a public Wi-Fi network. Most VPN companies have servers all around the world so users can connect as locally as possible the closer the server, the faster the speeds while connected. Some VPNs even encrypt users traffic multiple times through multiple servers, a process called multi-hop.
Web traffic is encrypted using the latest industry standards like AES-256, the SSL, or Secure Socket Layer, as well as SHA 2, the Secure Hash Algorithm. Once the VPN creates the encrypted tunnel, the users data is sent to the server using VPN protocols like TCP, Transmission Control Protocol, and L2TP, Layer 2 Tunneling Protocol. Of course, the user doesnt see any of this happening they just click connect and their web traffic is encrypted and their IP address is hidden.
What Is The Fastest VPN Connection Type
The fastest VPN connection type is SoftEther. IKEv2 is the fastest VPN connection for mobile devices.
SoftEther is faster than almost all VPN protocols because of its new VPN processing modules. Namely, the VPN processing modules are highly optimized. SoftEther is written in the C language and that also gives it the edge over other protocols. SoftEther is also one of the newest VPN protocols available and SoftEther takes full advantage of it by implementing rules that are tailor-made for high-speed throughput. Other protocols such as PPTP were not made with high-speed communication over the internet. Older protocols were more suited to packet transmission over narrow telephone lines.
The developers behind SoftEther made SoftEther with high performance in mind. SoftEther, when processing a given VPN packet, reduces the number of memory copies needed for each cycle.
SoftEther is faster than other protocols also because SoftEther can resolve Maximum Transmission Unit problems most efficiently. Unlike older protocols where VPNs must transmit data packets into tunnels, SoftEther adopts a different approach called the streaming tunneling mechanism.
For mobile, the IKEv2 protocol is the fastest since IKEv2 doesnt consume as many CPU resources. Of course, there are many other factors why IKEv2 is the fastest but the main reason why IKEv2 is the fastest especially on mobile devices is that it is very efficient at reconnecting a user whenever there is a weak VPN connection.
What Is A Kill Switch
Thanks to the vagaries of the internet, VPN connections sometimes fail. In the normal course of events, when this happens you will remain connected to the internet but without the protection of the VPN.
A kill switch protects you against this by preventing connections into and out of your device unless the VPN connection is active.

Can I Use A VPN On All My Devices
Every VPN provider allows you to install its software on as many devices as you like. Most, however, limit how many devices you can use at the same time with a single account. We refer to the number of devices a VPN allows you to use at once as the number of “simultaneous connections” it permits.
VPNs typically allow up to five simultaneous connections, although this number can vary considerably.
The majority of VPN services offer iOS VPN apps as well as VPNs for Android users, however, it may be difficult to find support for less popular mobile operating systems. When it comes to computer clients, most VPN services support Windows and Mac users, but Linux VPN clients can be more difficult to find.
Does A VPN Make Me Anonymous
No matter how a service advertises itself, VPNs provide privacy, not anonymity. This is mainly because the VPN server can see everything that your ISP normally can.
However, unlike your ISP, good VPNs do not log this information and therefore provide much higher levels of privacy than you normally have when surfing the internet. Even these, however, will start to log information if subpoenaed or issued a binding court order.
No VPN staff are going to risk jail for you! Does this mean VPNs are useless for privacy? Not at all. Such legal moves are highly targeted against individuals of interest, so are not a threat to the privacy of most ordinary VPN users.
The Edward Snowden’s of this world, however, who require very high levels of true anonymity, should use the Tor Network rather than VPNs to protect their identity.

What Are VPN Protocols
Letâs start with the basics. VPN stands for virtual private network, which is a secure tunnel between two or more devices. When you use a VPN, you are connected to the internet through an intermediary server run by the VPN provider .
The security of your connection is dictated by the VPN protocol, a set of instructions that defines how your device communicates with the VPN server.
Selecting Your VPN Provider
What makes for a VPN provider? Aside from the most obvious matter, a good price point that sits well with your budget, other elements of VPN selection can be a bit opaque. Lets look at some of the elements youll want to consider.
Its up to you to answer these questions by reading over the documentation provided by the VPN service provider before signing up for the service. Better yet, read over their documentation and then search for complaints about the service to ensure that even though they claim they dont do X, Y, or Z, that users arent reporting that they are in fact doing just that.

What Is The Most Secure VPN Protocol
Lightway, IKEv2, L2TP, and OpenVPN are all secure protocols, but the title of the most secure VPN protocol should go to Lightway, which uses wolfSSL, a well-established cryptography library that is FIPS 140-2 validatedâwhich means it has been rigorously vetted by third parties. Lightway core code has been audited and open-sourced so that it can be transparently and widely scrutinized for security vulnerabilities.
OpenVPN is also recommended, because it has been extensively audited by multiple neutral experts. Its open-source implementations are available for anyone to inspect and improve.
Free Vs Paid VPNs: Which Is The Best For You
In general, paid VPNs are better than the free ones. The latter have to rely on ads and selling your data , unless they are offered by a premium VPN provider. However, that doesnt mean you cant find a good free VPN its just that they will have one or more limitations that often are a deal-breaker.
The most common free VPN limitations are as follows:
- Speed. Most free services are slower than paid ones. While you might be able to stream in full HD using some VPNs, expect a serious drop-off in speeds.
- Servers. Free VPNs usually offer only a few servers in the US, the Netherlands, and some other countries. Also, those servers tend to be overloaded and have high latency, which is bad for gaming and VoIP calls.
- Data limit. Freemium VPN services will often give you a certain amount of GBs per month or MBs per day. Therefore, downloading large files or streaming high quality videos will soon leave you blocked until next month.
- Number of devices. Expect to get only one connection per account. This means that you wont be able to use a free VPN on both your computer and your smartphone.
- Geo-blocking and P2P. You wont be able to use Netflix and other streaming platforms with most VPNs. Whats more, some of them also prohibit torrenting, especially if they dont have a data limit.

Faq: Connection Protocols For VPNs
The following are the most common questions asked about VPN connection standards.
What is the best VPN protocol?
Each VPN protocol serves a different purpose and has different strengths and weaknesses. Therefore, the best depends on your use case. For example, proven security points to OpenVPN, while speed and agility might require the newer Wireguard.
What is the fastest VPN protocol?
The fastest connection standard is generally considered to be PPTP, which stands for point-to-point tunneling protocol. Its great for streaming video content, but its important to note that it doesnt offer a high degree of security.
What is the most secure VPN protocol?
OpenVPN and Wireguard are widely considered the most secure optionss available to most people. Both offer 256-bit encryption and an open source code base that has been critically reviewed. SSTP is also quite a secure connection, but since its controlled by Microsoft, it doesnt work on all devices.
Why should I change the connection protocol on my VPN?
In most cases, you shouldnt change the VPN connection protocol often. The best VPN services will automatically choose the fastest connection for you. There are times, however, when you just wont connect. Its also possible that you might want faster speeds, more stability or greater security.

How To Configure Your VPN
VPN software is designed to be easy to use, and should “just work” without the need for any additional configuration. Unfortunately, this is not always the case. This is especially true if you have an IPv6 internet connection as many VPN apps struggle to handle the new internet standard correctly. It is therefore always a good idea to check that your VPN is correctly configured to protect you as it is supposed to.
Examples Of Personal VPN Services
Weve tested hundreds of personal VPNs over the years. Currently, our top five recommended services are:
Heres how it works:
The user connects to the VPN and is authenticated.
Authentication options might include passwords, physical tokens such as smart cards, or biometric devices such as fingerprint scanners. In some cases, certificates can be used so the authentication happens automatically in the background.
The VPN tunnel is established between the users device and the server.
In a remote access VPN, the VPN tunnel connects to the devices physical IP address, which is tied to its internet connection. In a mobile VPN, the VPN tunnel connects to a logical IP address, which is tied to the device, and so is independent of the internet connection.
The VPN connection persists as the user switches between different networks.
If the user is mobile, they might switch between networks . Their physical IP address can change, but the logical IP address the VPN tunnel uses stays the same. The virtual network connection remains intact, so the user can continue working seamlessly as long as they have any connection.
If the device is turned off to preserve the battery life, the VPN connection is still available when the device is switched back on.

What Are The Benefits/advantages Of Using A VPN
Why Is Online Privacy So Important
The internet is expanding exponentially. As more people start using smart devices, they risk exposing intimate personal data online. And with ISPs tracking, storing, and selling the browsing history, habits, and behavior of their customers, its essential to lock down your private data.
Your personal information should be just that personal. Without privacy protections, you may be exposing yourself to identity theft and other cybercrimes, as well as tracking by advertisers, your ISP, and your government.

What Do VPNs Cost
There are free VPN services, but if you want reliable download speeds, support, easy set-up and the most features, the cost of a paid VPN is well worth it. Most VPN services will generally cost anything from $5 to $15 per month for an individual user, but choosing one based on the cheapest price isn’t the best way to go. While price can play a part in your final decision, where multiple services offer similar benefits, you need to look at how each provider meets your particular needs.
How Do You Test VPNs
When testing VPNs, we check every aspect that might be of concern. To begin with, we look at what personal details a service needs, and any essential features like encryption. Then we consider pricing, and whether money-back guarantees are on offer, and whether it works on other operating systems as a Mac VPN or Linux VPN as well as on Windows.
During the physical testing, we test speeds over a number of servers, check for DNS leaks, test kill switch functionality plus any and all other additional features, and measure connection time and if the apps crash.
Finally, we review how easy the apps are to use, and test the services on desktop and mobile devices.

Are There Any Downsides To Using A VPN
The added security and privacy youll get with a VPN makes them an essential tool for internet safety. VPN disadvantages are few, but one side effect might be a slight reduction in your internet speed. This is because a VPN encrypts your internet connection and redirects it through a VPN server.
The VPN marketplace is highly competitive, and many leading VPN providers are committed to keeping their services as fast as possible.
What’s The Fastest VPN
When a VPN is active, your web traffic is taking a more circuitous route than usual, often resulting in sluggish download and upload speeds as well as increased latency. The good news is that using a VPN probably isn’t going to remind you of the dial-up days of yore.
Most services provide perfectly adequate internet speed when in use, and they can even handle streaming HD video. However, 4K video and other data-intensive tasks like gaming over a VPN are another story.
When we test VPNs, we use the Ookla speed test tool. This test provides metrics for latency, download speeds, and upload speeds. Any one of these can be an important measurement depending on your needs, but we tend to view the download speed as the most important. After all, we live in an age of digital consumption.
To evaluate VPNs, we first run several speed tests without the VPN. Then, we compare that figure to speed tests taken with the VPN active and find a percent change. Our speed tests stress comparison and reproducibility. That means we stand by our work, but your individual results may vary. After all, perhaps you live on top of a VPN server, or just happen to have a super-high bandwidth connection. Please read our feature, conveniently named How We Test VPNs, if you want the full details.

A VPN keeps your secrets especially financial information safe. A VPN secures your computer’s internet connection so that all the data you’re sending and receiving is encrypted. It does this by creating a secure ‘digital tunnel’ between you and your online destinations. Others can’t see what’s going on in the tunnel, so they can’t spy on your web browsing or know where you’re located.
As far as websites can tell, you’re at the location of one of many worldwide servers that your encrypted data passes through. That’s how you can get around geographical restrictions or extra costs that can come from shopping overseas online. To them, it’ll look like you’re based at the location of the nearest server used by your VPN service.
