The encryption and decryption processes depend on both the sender and the receiver having knowledge of a common encryption key. Intercepted packets sent along the VPN connection in the transit network are unintelligible to any computer that does not have the common encryption key. The length of the encryption key is an important security parameter. Computational techniques can be used to determine the encryption key. Such techniques require more computing power and computational time as the encryption key gets larger. Therefore, it is important to use the largest possible key size.
Google Chrome has a built-in task manager to help users find out the runtime statistics of each tab. When you open up too many tabs and what to kill some of them to release more memory or CPU, task manager is a great tool. Let’s dive in. Open Task Manager You can access Task Manager by clicking on the three-dot icon on the right side of the address bar, going down to More Tools and then select Task Manager.
Perfect Privacy holds the top spot as the best VPN for advanced online anonymity. While it may be overkill for basic users, this is a powerful VPN with advanced online anonymity features you will not find anywhere else. It is a well-regarded service that has earned high praise from the tech community for exposing vulnerabilities and flaws other VPN providers.
We are well aware that some of you are concerned about the prices while others want best vpn service in the world and some users want most secure encryption more than anything else. Considering these factors we mention some tips for your ease choosing the fast vpn for your use based on our through research about each vpn service and years of industry experience.
L2TP uses UDP messages over IP networks for both tunnel maintenance and tunneled data. The payloads of encapsulated PPP frames can be encrypted or compressed (or both); however, L2TP clients do not negotiate the use of MPPE for L2TP connections. Encryption for L2TP connections is provided by IPSec Encapsulating Security Payload (ESP) in transport mode.
Among the most critical is how to communicate and exchange information securely between employees sitting at multiple locations. Here is where a VPN or a Virtual Private Network proves to be very handy. It is a fast, reliable, and secure way to exchange information across computer networks, and an excellent, secure mode of communication from remote locations.
Here's the problem with the internet: It's inherently insecure. When the internet was first designed, the priority was to be able to send packets (chunks of data) as reliably as possible. Networking across the country and the world was relatively new, and nodes often went down. Most of the internet's core protocols (methods of communicating) were designed to route around failure, rather than secure data.
Central America isn’t the first place you’d think of when it comes to cutting edge technology, but NordVPN is up there with the best VPN services in 2018. It has 1015 servers in 59 countries, supports up to six devices simultaneously, runs 2048-bit encryption and has a feature list including an automatic kill switch, dedicated IP addresses, strong DNS leak protection and the ability to pay in Bitcoin. For relatively short connections performance was superb, although we did notice a little latency creeping in from time to time for very long distance connections. However, browsing remained snappy and performance wasn’t degraded significantly. We’d recommend hunting the site for its free trial and if you like it, signing up for the 3-year plan which is currently going for just $99!
One popular technology to accomplish these goals is a VPN (virtual private network). A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. The VPN uses "virtual" connections routed through the Internet from the business's private network to the remote site or employee. By using a VPN, businesses ensure security -- anyone intercepting the encrypted data can't read it.

Today, the Internet is more accessible than ever before, and Internet service providers (ISPs) continue to develop faster and more reliable services at lower costs than leased lines. To take advantage of this, most businesses have replaced leased lines with new technologies that use Internet connections without sacrificing performance and security. Businesses started by establishing intranets, which are private internal networks designed for use only by company employees. Intranets enabled distant colleagues to work together through technologies such as desktop sharing. By adding a VPN, a business can extend all its intranet's resources to employees working from remote offices or their homes.
Everything you do on the Internet has to pass through your own ISP before reaching the destination. So, when you request Google, for example, the information is sent, unencrypted, to your ISP and then passes through some other channels before reaching the server that holds Google’s website. Basically, VPN services privatize information that can be read by ISPs or any other agency that inspects your traffic.
VPN servers work by routing traffic through a series of external servers before they reach the server, and a traffic flow from one server to another is called a “hop.” To maximize the connection speed, you want the least hops possible. If you do not have a specific reason to connect through another country, your best course of action should connect to the server closest to your current location. For many, it means choosing your country home (and closest to the city,) if you are in a country with multiple VPN servers available. For others, i.e. selecting the country closest to your own.
A “kill switch” goes by many names, but the term describes VPN software that shuts off all network traffic in and out of your computer if the encrypted connection fails. A hiccup in your Wi-Fi or even with your ISP can cause a VPN to disconnect, and if you then maintain an unsecure connection—especially if the VPN software doesn’t alert you that it’s no longer protecting your traffic—that wipes out all the benefits of your VPN. We considered kill switches to be mandatory. And although we looked for apps that made it easy to add rules about when to activate kill switches, we considered special config files or manual firewall tweaks to be too complex. (iOS doesn’t support any kill-switch features; we address a few iOS-specific problems that apply to all VPN services in a separate section.)
We have tested dozens of VPN providers in our quest to find the most reliable and fast secure VPNs. During our test, we found that a lot of VPN services falls short on the minimum speed benchmark requirements we have set. Hence we excluded them from our fastest VPN list. This doesn’t mean that those VPNs are not good, but we aim to rank the ones that give top-notch VPN speed on the grounds of many factors. Below are the top 5 fast VPN providers that secured the position in our list of high-speed VPNs to use in 2018.

Everyone wants to keep their browsing activity safe and secure, but not at the expense of compromising on speed, right? This is where a fastest VPN service comes in. But why there’s a need for a fast VPN, don’t you trust your Internet provider? This WHY has multiple answers, but the best to quote here is that VPN slows down the internet, seriously? Yes, depends on the VPN you’re using. People all around the world use VPN services not only for their security but for various other entertainment purposes like streaming and downloading torrents. They look for the fastest VPN which not only keeps their browsing activity safe but also let them be the fastest on the radar.
ExpressVPN has a wide range of client software, a dedicated proxy service for streaming media and its own DNS service. But in our 2017 tests, it dropped many connections and its overall performance was in the middle of the pack. It also allows only three devices to be connected simultaneously per account, and it's one of the most expensive services we evaluated.
However, if you’re using a top-tier VPN service, the difference in speed usually isn’t noticeable, and can sometimes speed up your connection. You can still watch streaming videos and download large files without interruption. Our VPN servers are among the fastest in the industry and we work hard to keep it that way. Download Hotspot Shield VPN and get privacy protection without sacrificing speed.
Tunneling protocols can operate in a point-to-point network topology that would theoretically not be considered as a VPN, because a VPN by definition is expected to support arbitrary and changing sets of network nodes. But since most router implementations support a software-defined tunnel interface, customer-provisioned VPNs often are simply defined tunnels running conventional routing protocols.
Latency normally results in a poor VPN connection. If you are connected to a VPN server that is far from your location, the chances are that your VPN speed will lag. An ideal way to turn your VPN account to a fast VPN connection is to choose your VPN location smartly. Your connections will become a high-speed VPN if you select a server that is near close to your original location, and it not overfilled.
If the only use case you care about is securely accessing your home network to, then you absolutely do not need to invest in a VPN service provider. This isn’t even a case of the tool being overkill for the job; it’s a case of the tool being wrong for the job. A remote VPN service provider gives you secure access to a remote network (like an exit node in Amsterdam), not access to your own network.
VyprVPN allows you to quickly access over 200,000 IP addresses with 700+ servers in 70+ worldwide locations in North America, South America, Europe, Asia, Africa and Oceania. Connections are always available, so you can access your favorite websites quickly. With Golden Frog's fast VPN service, you can restore your freedom and bypass location-based IP blocking imposed by restrictive governments. We don't believe in limitations, so you can connect to any VyprVPN server at any time, without restrictions or download caps.
In conjunction with information security experts at The New York Times (parent company of Wirecutter), we reached out to our finalists with questions about their internal security practices. We asked how they handled internal security access, how they communicated securely with customers, in what ways they collected reports on security bugs, and of course whether their statements on logging policies matched their marketing and privacy policies. We also considered which companies had public-facing leadership or ownership, and which ones openly supported projects and organizations that promoted Internet security and privacy. (For a full breakdown of trust and VPNs, check out the section above.)
We have split our fastest VPN speed test into two parts; without a VPN connection and with a VPN. We will be testing VPN speeds from a US connection with a stable Internet connection. With VPN, we have chosen to connect to a location that is far from the United States, let’s pick the UK. It is important to understand that VPN speed is directly related to the distance of the connection. As the distance increases, chances are there that you might report slower VPN connection speed.

Our VPN reviews instead stress value and technical excellence. The number of devices that can be used with an account is, in our opinion, more important. We also prefer VPN services with lots of servers and a good geographic distribution of those servers. VPNs that are easy to set up and use for first timers and include a well-made local client also go a long way toward getting PCMag's endorsement. And, of course, price is a major issue. The average monthly price of a VPN right now is $10.48. If a VPN is charging more, it had better be offering something compelling.
We’ve shown you how to build your own VPN for remote gaming and browsing that also protects your security, shown you how to make a VPN even more secure, and shown you dozens of services that operate free and paid VPNs you can sign up for and use. We’ve even put the question to you several times to tell us which VPN service providers you think are the best. So how do you pick a solid VPN service?
In the configuration shown in the following figure, the firewall is connected to the Internet and the VPN server is another intranet resource connected to the perimeter network, also known as a screened subnet or demilitarized zone (DMZ). The perimeter network is an IP network segment that typically contains resources available to Internet users such as Web servers and FTP servers. The VPN server has an interface on the perimeter network and an interface on the intranet.
Our team also understands the individual need of vpn by our users since some users are more concerned about their online privacy and security whereas others are more focused towards speed and features. Some potential customers also want easy service. All these factors have been taken into account by our team and a detailed review has been written which will help you in selecting the fast vpn service for you.
The IVPN app’s default settings are great for most people, who should be happy just smashing the Connect button and not fiddling with settings. The desktop app defaults to a secure OpenVPN connection with AES 256-bit encryption (what we consider the standard at this point), and the mobile app can (and should) be toggled to OpenVPN as well. Our budget pick, TorGuard, defaults to the weaker (but also acceptable) AES 128-bit encryption unless you manually change it, and hasn’t added OpenVPN support on its iOS app.

Business security and strength. Businesses aren’t immune to hacking and someone getting into your system to access consumer records could be a catastrophe and lead to significant losses for everyone involved. Some businesses operate on multiple networks, potentially leaving entryways for thieves. Remote businesses are becoming the norm and employees could become targets for passage into large and secure systems. Using a VPN helps prevent such situations from happening, regardless of whether or not you’re on a public network. Your network will be encrypted, and your business will remain secure.


This is important to understand. Consumer VPN services protect your transmission from your location to their location, not from your location all the way to the destination application you're using. If you think about it, this makes sense: A consumer VPN service is operated by a completely different company than, for example, Facebook or your bank.
Some VPN services will limit the total amount of data you can send and receive, either in one connection session or over the period of a month. Other VPN services will limit the speed of the data, effectively sharing less of their pipe with you than might be optimal. That could slow your browsing experience to a crawl or completely prevent you from watching streaming video.

These VPNs have been rated as the top all-around VPN software providers and will be able to cater to any of your VPN needs. Whether that be unblocking Netflix, torrenting safely or simply browsing the internet privately and securely these 10 VPNs do it all. Let’s take a closer look and dive into the detail on exactly why we recommend these VPN services.


Torrenting/P2P Support – IPVanish makes all torrent websites and clients accessible. There is no problem with IPVanish as far as support for P2P networking is considered. However, the fact that IPVanish is based in the US and subject to its laws makes it a poor choice if your main purpose of having a VPN is to download torrents. This is because companies have no power against agencies and if they are trying to monitor a specific user, the company would probably have no choice but to comply and leak user data. In short, do not use IPVanish for torrenting to ensure your safety.

IP / DNS Leak Test – Security is another crucial factor in my best review process since one of the main purposes of a VPN is to enhance the security of users. Some poor VPN services leak the IP or DNS of the user, which can expose their activities and identity online. It goes without saying that such VPN services are a waste of money and must be avoided at all costs.
TunnelBear is the undisputed best free VPN service available today. It's a serious VPN that's serious about customer satisfaction, privacy and security. So the upside is that you're getting a VPN that works, and can be trusted not to hold loads of data on you and sell you out at the earliest opportunity! The downside is that the free tier of TunnelBear only gets you 500MB bandwidth each month. That means for many people having it always-on will leave you caught short well before the end of the month, and absolutely rules out using it to stream endless episodes of Rick and Morty on Netflix. The free VPN tear at TunnelBear is certainly designed as a gateway to the paid tier which offers unlimited data but will cost you real money. If you're going to pay for a VPN we'd suggest getting a premium one like Express, but if you're only interested in a free option then TunnelBear is the one for you unless you need loads of bandwidth.

Internet Protocol Security (IPsec) was initially developed by the Internet Engineering Task Force (IETF) for IPv6, which was required in all standards-compliant implementations of IPv6 before RFC 6434 made it only a recommendation.[7] This standards-based security protocol is also widely used with IPv4 and the Layer 2 Tunneling Protocol. Its design meets most security goals: authentication, integrity, and confidentiality. IPsec uses encryption, encapsulating an IP packet inside an IPsec packet. De-encapsulation happens at the end of the tunnel, where the original IP packet is decrypted and forwarded to its intended destination.
An impressive and fast VPN service, Buffered VPN offers total online security and world-class customer support. The service boasts of providing access to content from any country in the world. This is achieved through the service’s server locations in 45 countries. It supports Windows, Linux and Mac platforms, but can also be set up on Android and iOS. The service offers excellent latencies and fast upload speeds, very good for browsing.
MPPE provides only link encryption between the VPN client and the VPN server. It does not provide end-to-end encryption, which is data encryption between the client application and the server hosting the resource or service that is being accessed by the client application. If end-to-end encryption is required, IPSec can be used to encrypt IP traffic from end-to-end after the PPTP tunnel is established.
To work around this problem, instead of having the client create a new default route when a connection is made, administrators can configure the client’s routing table with specific routes that direct packets to the organization’s network over the VPN connection. While connected to the intranet, the client can obtain Internet access using the default route that points to the Internet. This configuration is known as split tunneling.
Final Verdict – NordVPN is easily one of the best all-around providers. I would especially recommend this VPN for users that value their privacy. The encryption protocols, jurisdiction, and logging policies of NordVPN make it the perfect VPN for users concerned about their privacy. And its Double VPN feature makes it stand out from the crowd, something I have covered in detail in NordVPN review.

CyberGhost’s popular free tier might not offer amazing speeds, but its paid Pro tier is a real contender.  It proved to be both quick and consistent in our speed tests. An “extra speed” feature can be toggled before you connect for an extra boost. Setup and use are novice-friendly, and live chat with customer support is available if you need a hand. Military grade encryption ensures all your data is safely tunneled to the VPN server, and CyberGhost does not store any logs of user activity or other identifiers.
If you are a torrent lover, you know speed matters. Torrent lovers usually get foiled with slow internet connection and end up finding alternatives. With fastest VPN service, you can enjoy the top-notch downloading experience without any restrictions. High-speed VPNs not only give you the best torrenting experience but also anonymize all your activities. To be in a win-win situation, use fast VPN service today and not only increase your torrent speeds but encrypt all your data and get rid of ISP throttling. We have also covered a detailed post on how to download a torrent file safely on your  PC and mobile devices, have a read!

Now coming back to the recommendation – I am a big fan of ExpressVPN as personally I have never encountered an issue while downloading torrent with this premium fast VPN connection. I download 2-3 torrent files every week, and for me the German and Florida server works like a charm. I only see a drop of 10% in speed compared to what I get without a VPN, which is a fair reduction.


In recent times, VPN services have made giant leaps in growing from niche online products hidden away in a dark corner of the internet to almost must-have services for anyone with an internet connected device. VPN is very much in the mainstream now and luckily that broadened appeal has done wonders for the usability of the services themselves - there are some brilliant options available in 2018.
They even offer the most generous simultaneous connection count, with six simultaneous connections through their network, where everyone else offers five or fewer. NordVPN's network isn't as large as some of their competitors, so if you're trying to obfuscate your tracks, you might want a company with more servers. Otherwise, this company is clearly providing a winning offering.
We're not cryptography experts, so we can't verify all of the encryption claims providers make. Instead, we focus on the features provided. Bonus features like ad blocking, firewalls, and kill switches that disconnect you from the web if your VPN connection drops, go a long way toward keeping you safe. We also prefer providers that support OpenVPN, since it's a standard that's known for its speed and reliability. It's also, as the name implies, open source, meaning it benefits from many developers' eyes looking for potential problems.
