Challenge Handshake Authentication Protocol (CHAP) is an encrypted authentication mechanism that prevents transmission of the actual password on the connection. The NAS sends a challenge, which consists of a session ID and an arbitrary challenge string, to the remote client. The remote client must use the MD5 one-way hashing algorithm to return the user name and a hash of the challenge, session ID, and the client’s password. The user name is sent as plain text.


Some VPN services provide a free trial, so take advantage of it. Make sure you are happy with what you signed up for, and take advantage of money-back guarantees if you're not. This is actually why we also recommend starting out with a short-term subscription—a week or a month—to really make sure you are happy. KeepSolid VPN Unlimited offers a one-week Vacation subscription, for example. Yes, you may get a discount by signing up for a year, but that's more money at stake should you realize the service doesn't meet your performance needs.
With hundreds of VPN services and clients available, it can be difficult to decide which one to use. We've extensively tested several popular VPN services that met three requirements: They had both desktop and mobile client software (with one exception), they had VPN servers in many countries, and they offered unlimited data use, at least in their paid versions.
Not all the VPN protocols work fast. It is not that VPN doesn’t work fast, but all the protocols are designed to fulfill specific needs of the users. We have already discussed the fastest VPN protocols used in our VPN speed test. We are now detailing more features about each protocol to give you more reasons to choose the best one that fits your specific needs.
The biggest advantage of RIP is that it is extremely simple to configure and deploy. The biggest disadvantage of RIP is its inability to scale to large or very large networks. The maximum hop count used by RIP routers is 15. Networks that are 16 hops or more away are considered unreachable. As networks grow larger in size, the periodic announcements by each RIP router can cause excessive traffic. Another disadvantage of RIP is its high recovery time. When the network topology changes, it might take several minutes before the RIP routers reconfigure themselves to the new network topology. While the network reconfigures itself, routing loops might form that result in lost or undeliverable data.
Some countries don't have the same protections for freedom of press, speech, and expression that most democratic countries have. In fact, some regimes resort to oppressive measures to monitor and take action against those they see as threats to the government. People who dare to stand up have to take extra precautions to protect their communications. Journalists and researchers also send messages containing data that some people may want to try very hard to intercept.
Jurisdiction – ZenMate is based in Germany, which is a country with one of the freest Internet in Europe. Online freedom is protected in the country and it does not have a history of persecution against bloggers and social media activists. Nonetheless, it is still part of the 14 Eyes alliance, which implies that users should be careful when considering ZenMate.
ProtonVPN is a VPN from Switzerland. The software is easy to use and provides all the features necessary to keep your data secure both at home and while on public WiFi. Servers are located around the world, and because ProtonVPN uses a Secure Core network of servers – it will provide fantastic speeds for streaming. Proton permits P2P for torrenting on some of its servers. In addition, it can be installed and used on five simultaneous devices. That means you can protect all your devices with one account. The VPN is zero logs (it never stores IP addresses) and the time of your last session is deleted every time a new session is started.
IVPN excels at trust and transparency, the most important factors when you’re choosing a virtual private network. After interviewing IVPN’s CEO, we’re convinced that IVPN is dedicated to its promises not to monitor or log customer activity. But a trustworthy VPN is only as good as its connections, and in our tests IVPN was stable and fast. IVPN apps are easy to set up and use with secure OpenVPN connections on Windows, macOS, Android, iOS, plus a few other platforms. Extra features like automatic-connection rules and kill switches to block data on unsecured connections add protection and value that make it worth a slightly higher price than some competitors.
It’s not suitable for users who want to unlock geo-restricted content as well as improving their privacy. The free version only offers U.S.-based servers, and access to services like Netflix Which VPNs Still Work With Netflix? Which VPNs Still Work With Netflix? Netflix is trying to stop people accessing its service through VPNs, but a handful of VPNs are managing to stay one step ahead of the streaming giant. Read on to find out which ones... Read More , Hulu, and BBC iPlayer are only available to premium users.
There are some minor disadvantages to using a dynamic IP. If someone who previously had the IP address you've been assigned did something nefarious on a service you use, it's possible that IP address might be banned. Usually, VPN providers are very careful about checking their IP addresses against blacklists, so the chances of this being a problem for you are slim.
Kodi is becoming the next biggest platform for streaming world’s content, and it’s not possible that binge-watchers are unaware of this gigantic media center. Kodi community would relate the only reality that Kodi addons are geo-restricted; you need to be in the specific region to stream your desired or better to say all the best Kodi addons. Kodi is all about streaming content using addons, means if you’re planning to use a Kodi VPN to stream addons, make sure the VPN should be uber-fast.
Hotspot Shield VPN does not log your browsing activity. Almost all Internet Service Providers (ISPs) track your browsing history. So when you use a VPN like Hotspot Shield, there is no record of the websites you have visited and which apps you use. This prevents hackers from exploiting vulnerabilities in these websites/apps to get to your personal information.

Business VPN by KeepSolid is an affordable VPN service that supports remote access VPN  and offers premium VPN servers dedicated to your business. Built for SMBs, remote officers, on-the-go employees, and PR & Advertising companies, this platform touts an administrative portal for efficient team management alongside military-grade, 256-bit encryption to safeguard both corporate data and customer information.


CyberGhost is one of the most feature-rich VPNs with special configurations for different use cases, including media streaming, downloads, anti-censorship and safe browsing. Ultimately designed to optimize your connection, this turned out to be quite irrelevant when looking at the download speed, which came out lowest across all testing tools, with an average speed of 2.47 Mb per second.
The best VPNs offer a solid balance of features, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards getting around the location restrictions companies put on their apps and services, and others are targeted at people who do heavy downloading and want a little privacy while they do it. Here’s what you should look for.

GRE is sometimes used by ISPs to forward routing information within an ISP's network. To prevent the routing information from being forwarded to Internet backbone routers, ISPs filter out GRE traffic on the interfaces connected to the Internet backbone. As a result of this filtering, PPTP tunnels can be created using PPTP control messages, but tunneled PPTP data is not forwarded.
Proximity: Choosing a server close to your own location will result in a speedier connection. If you’re in Asia and want to access American content, then choose a server on the west coast USA. If you’re in Europe, then use an East Coast server. If you know the location of the server hosting the content you’re trying to access, you can also choose a VPN server near there.
Protocol: When you’re researching a VPN, you’ll see terms like SSL/TLS (sometimes referred to as OpenVPN support,) PPTP, IPSec, L2TP, and other VPN types. We asked Samara Lynn, Lead Analyst for Networking and Small Business at PCMag, whether or not a user shopping for a VPN should shop for one over another. “SSL is what is commonly used these days. All of these protocols will provide a secure connection,” she explained, and pointed out that most solutions are invisible to the end-user anyway. Strictly, each protocol has its benefits and drawbacks, and if you’re concerned about this (specifically, PPTP vulnerabilities,) you’re probably already aware of them. Most users don’t need to be concerned about this—corporate users on the other hand, are probably all using IPSec or SSL clients anyway.
Authentication that occurs during the creation of a PPTP-based VPN connection uses the same authentication mechanisms as PPP connections, such as Extensible Authentication Protocol (EAP), Microsoft Challenge-Handshake Authentication Protocol (MS-CHAP), Microsoft Challenge-Handshake Authentication Protocol version 2 (MS-CHAP v2), CHAP, Shiva Password Authentication Protocol (SPAP), and Password Authentication Protocol (PAP). PPTP inherits encryption, compression, or both of PPP payloads from PPP. For PPTP connections, EAP-Transport Layer Security (EAP-TLS), MS-CHAP, or MS-CHAP v2 must be used for the PPP payloads to be encrypted using Microsoft Point-to-Point Encryption (MPPE).
Providers can also log less-specific data about when or how often you connect to your VPN service. In some cases, these logs are a routine part of server or account management, and can be responsibly separated and scrubbed. In other cases, VPN providers take note of every connection and use that information to actively police individual customers. Though it’s reasonable for companies to protect their networks from abuse, it becomes a dealbreaker when companies keep extensive connection data for a longer period of time. Some VPN companies we spoke with explained how a log might note your current connection for authentication purposes, but that log is deleted as soon as you disconnect. This kind of “live log” isn’t a concern, and even those culled every few hours—or as long as the end of each day—shouldn’t be confused with logs of your traffic and online destinations.
Update: We’ve received some feedback that 10Mbps is too slow to get good test results. We would argue that 10Mbps is quite average for home internet across the world, and we run tests for average people.  While our tests might not be a good indication of speed if you’re paying for a 50 Mbps or 100 Mbps connection, the results are varied enough to get a statistically significant indication of overall performance. Furthermore, all the VPNs on the list officially offer unlimited bandwidth, so if you happen to be on an uncongested nearby server, chances are you’ll still be able to max out your available bandwidth. Finally, there is no point in having a fast VPN if it is unstable, doesn’t protect your privacy, doesn’t unblock the content you want, or doesn’t have a good range of servers to connect to. We excluded providers like TotalVPN which were very fast but had awful customer service, for example.
The user’s certificate could be stored on the VPN client computer or in an external smart card. In either case, the certificate cannot be accessed without some form of user identification (PIN number or name/password credentials) between the user and the client computer. This approach meets the something-you-know-plus-something-you-have criteria recommended by most security experts.

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!

A VPN (Virtual Private Network) is a technology that creates a private tunnel over the internet. All your online traffic is redirected to the VPN server. All data passing between your device and the VPN server you have connected to is securely encrypted. This means that your internet service provider (ISP) and anyone else spying on your traffic cannot see your data. Your ISP is still needed to connect you to the internet, but all it does is connect you to the VPN server. After that, it cannot see which other websites you visit or other internet resources you connect to. For the more techy of you out there, the VPN server acts as a proxy.
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.
As unprecedented amounts of data are generated and collected every day, organizations seek to infuse the power of artificial intelligence (AI) and deep learning to more effectively derive insights and new knowledge from data to optimize operations, create new products and services, and automate decisions. However, prior attempts at building and implementing do-it-yourself (DIY) platforms … Continue Reading...
CyberGhost gives Mullvad some stiff competition in the speed department, especially for locations in North America and Europe. It does a good job protecting user anonymity, too—requiring no identifying information and using a third-party service for payment processing—albeit not to the same degree as Mullvad. Add to that CyberGhost’s unique, easy-to-use interface, good price, and streaming unblocking (although not for Netflix), and this VPN is a solid choice. (See our full review of CyberGhost.)
For features, they offer multi-hop VPN cascades, advanced firewall configuration options (DNS and IP leak protection), port forwarding, NeuroRouting, Socks5 and Squid proxies, obfuscation features to defeat VPN blocking (Stealth VPN), and a customizable TrackStop feature to block tracking, malware, advertising and social media domains. They also give you an unlimited number of device connections and offer full IPv6 support across their server network.

HMA Pro (reviewed here) is slightly more complicated, but it’s far from difficult to understand. If you want to select your desired virtual location click the Location mode tab, click on the location name, and then choose your preferred location from the list. Once that’s done, click the slider button that says Disconnected. Once it flips to Connected, you’re ready to roll.


Torrenting/P2P support – Getting torrents to work with PIA is no problem. You can easily gain access to P2P sites and clients with PIA if they are blocked in your region. As with IPVanish, however, PIA complies with the DMCA (Digital Millennium Copyright Act) which protects the copyrights of content creators. Therefore, PIA should be avoided if you are looking for a safe to torrent.
If you’re seriously concerned about government surveillance—we explain above why that should be most people’s last consideration when choosing a VPN—some expert sites like privacytools.io recommend avoiding services with a corporate presence in the US or UK. Such experts warn about the “14 eyes,” a creepy name for a group of countries that share intelligence info, particularly with the US. IVPN is based in Gibraltar, a British Overseas Territory. We don’t think that makes you any worse off than a company based in Switzerland, Sweden, or anywhere else—government surveillance efforts around the world are so complicated and clandestine that few people have the commitment, skills, or technology to avoid it completely. But because Gibraltar’s status has been a topic of debate in other deep dives on VPNs, we’d be remiss if we didn’t mention it.
To verify that each service effectively hid our true IP address, we looked at a geolocation tool, DNS leaks, and IPv6 leaks. When connected to each service's UK servers, we noted if we could watch videos on BBC iPlayer, and using US servers we noted if we could stream Netflix. We also visited the sites of Target, Yelp, Cloudflare, and Akamai to check if our VPN IP addresses prevented us from accessing common sites that sometimes blacklist suspicious IP addresses.
Logging: When you connect to a VPN, you’re trusting the VPN service provider with your data. Your communications may be secure from eavesdropping, but other systems on the same VPN—especially the operator—can log your data if they choose. If this bothers you (e.g., you’re the privacy/security advocate or the downloader), make absolutely sure you know your provider’s logging policies before signing up. This applies to location as well—if your company doesn’t keep logs, it may not matter as much where it’s located. (There’s a popular rumor that US-based VPN providers are required to log, in case the government wants them. This isn’t true, but the government can always request whatever data they have if they do log.) For a good list of VPN providers that don’t log your activities when connected (and many that do), check out this TorrentFreak article.
Free VPN Providers are more likely to log your activities and serve contextual ads while you’re connected. They’re also more likely to use your usage habits to tailor future ads to you, have fewer exit locations, and weak commitments to privacy. They may offer great features, but if logging and privacy are important to you, you may want to avoid them. However, if you just need quick, painless security while traveling on a budget, they’re a great option.
VPNs secure your traffic and route it through an intermediary server so it can’t be traced. But if privacy is not of chief concern to you, then there are other alternative proxy methods that offer faster speed. A SOCKS proxy, for example, does pretty much the same thing as a VPN without the encryption. Without having to encrypt and decrypt traffic, SOCKS proxy users can get faster speeds and still mask their IP address.
You've heard the advice before: Whether you're in the office or on the road, a VPN is one of the best ways to protect yourself on the internet. But how effective are VPNs? What's the best one for you? What are the downsides? Our executive guide aims to answer all your VPN-related questions -- including a few you probably haven't thought about before.
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.

First I just want to say what a great website you have created, very informative. I am using Avast VPN on a Windows computer and Google Chrome browser. Without a VPN I am getting download speeds up to 180 MB, and 24 MB up, using Ookla to test speeds. Using Avast VPN drops that to 40-60 MB down and 2-3 MB up, and I have tried using multiple locations from Miami to Atlanta, NY, Chicago and Jacksonville. Miami and NY are classed as P2P. My location is S Florida. When I download torrents my speed falls drastically. With one torrent downloading I get 6 MB down and up. 2 torrents simultaneously 2.5 MB down and 1.4 MB up. 3 torrents 2 MB down and 1.5 up, and 4 torrents 1 MB down and up. I have conducted dozens of tests over the course of the day to get an average of the speeds. I had previously used Private Internet Access, which was faster at the beginning of my one year subscription, but the speeds deteriorated towards the end of that one year subscription to speeds similar to Avast’s. Do you have any suggestions for a fastest VPN for streaming and torrenting? I only download torrents once or twice a month.
Cost: To pay for NordVPN on a monthly basis will cost you $11.95/month. However, you can get it cheaper at $9.00/month or $6.99/month if you buy 6 or 12 months at once for $54.00 or $83.88, respectively. Nord is also running a special that allows you to purchase 2 years of service for $3.99/month when you pay the full $95.75 upfront every two years. There's a 30-day money back guarantee and a free 3-day trial option.  
As a business grows, it might expand to multiple shops or offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations.
TorGuard also lacks extra features that are nice to have, like automatically connecting to the VPN when you’re on an unknown Wi-Fi network (which IVPN offers) or split-tunneling to choose which apps do and don’t route through the VPN (which ExpressVPN supports). And it offers no option to automatically connect to the fastest server, a feature our top pick lacks as well. But if you have above-average knowledge of networking, you’ll appreciate TorGuard’s more in-depth settings pane, which allows you to add scripts or kill specific processes when the VPN disconnects—neither our top pick nor popular services like Private Internet Access allow that kind of control.
The only issue i've had with my OG Pixel XL is the fingerprint scanner died after a drop (My bad) but screen is still good. GPS seems to be going out, and has gone out in one of my friends, that is way more of a show stopper than the fingerprint. With that said every single Samsung I've ever had was replaced withing 8 months for something like the speaker or microphone breaking. My Pixel is almost 2 years old with a lot of use daily.
ExpressVPN sets the bar when it comes to download speed. It’s always near the top of the rankings, albeit never at the peak. Consistency is a defining factor of Express; volatility is rarely an issue that affects the outcome of test results. Connections drop a little more often than we’d like them to, but the company has done a remarkable job considering the size of the network it manages.
Required only when the VPN server is acting as a VPN client (a calling router) in a site-to-site VPN connection. If all traffic from TCP port 1723 is allowed to reach the VPN server, network attacks can emanate from sources on the Internet that use this port. Administrators should only use this filter in conjunction with the PPTP filters that are also configured on the VPN server.
The best VPNs offer a solid balance of features, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards getting around the location restrictions companies put on their apps and services, and others are targeted at people who do heavy downloading and want a little privacy while they do it. Here’s what you should look for.
Despite some of the drawbacks, ZorroVPN is a very interesting service if you are looking for advanced online anonymity. With their OpenVPN file config generator, you can create unique VPN chains with the Tor network and proxies (up to four hops). Unlike with Perfect Privacy, however, these multi-hop configurations cannot be dynamically changed within the VPN client.

VyprVPN is a powerful contender if you’re after performance and security. It boasts great speeds due to a staggering network of 700+ serves and more than 200K IP addresses. They own and manage their servers, which translates into reliable uptime, lag-free performance, top-notch support and great speeds. Add in unlimited bandwidth and P2P support, successful handling of Netflix and Steam geo blocks, and you can check all your VPN must-have features right off the bat.
Most VPN providers don’t give you the option, anyway, but don’t disable encryption altogether. Additionally, 128-bit AES is the minimum strength encryption necessary for a VPN to do its job and keep your data safe. It’s effectively un-crackable and is slightly faster than 256-bit AES, which is also common. A handful of VPNs use Blowfish encryption, which tends to be slower than its AES counterpart. We recommend at least 448-bit Blowfish encryption if you go that route.
If VPN connections get blocked by your network because of strict network management or government censorship, TorGuard offers a “stealth” connection to avoid deep packet inspection. Specifically, TorGuard uses Stunnel (a clever portmanteau of SSL and tunnel) to add an extra layer of encryption and make your traffic look like normal, secure Web traffic. If you’re having connection issues, you can enable Stunnel with a checkbox on the main application window, but only if you select TCP from the protocol list. (Otherwise, the box is unclickable, with no explanation as to why.)

With the single-adapter model, also known as the NBMA model, the network for the frame relay service provider (also known as the frame relay cloud) is treated as an IP network and the endpoints on the cloud are assigned IP addresses from a designated IP network ID. To ensure that OSPF traffic is received by all of the appropriate endpoints on the cloud, the frame relay interface must be configured to send unicast OSPF announcements to all of the appropriate endpoints. For the server running Routing and Remote Access, this is done by designating the interface as an NBMA network and adding OSPF neighbors.


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.
While VPNs are an important tool, they are far from foolproof. Let’s say you live in an oppressive country and want to evade censorship in order to access the unrestricted web. A VPN would have limited use. If you’re trying to evade government restrictions and access sites like Facebook and Twitter, a VPN might be useful. Even then, you’d have to be somewhat dependent on the government’s willingness to look the other way.
There is a PPTP control connection between the IP address of the PPTP client using a dynamically allocated TCP port and the IP address of the PPTP server using the reserved TCP port 1723. The PPTP control connection carries the PPTP call control and management messages that are used to maintain the PPTP tunnel. This includes the transmission of periodic PPTP Echo-Request and PPTP Echo-Reply messages to detect a connectivity failure between the PPTP client and PPTP server. PPTP control connection packets consist of an IP header, a TCP header, a PPTP control message, and a data-link trailer and header as shown in the following figure:
The solution is downloadable and supports platforms such as OS X, Windows and Linux. Mobile systems like Android and iOS are also supported. These capabilities enable users to use the product on desktops, laptops, smartphones or tablet computers. The software can also be downloaded onto network routers, ensuring that all devices connected to such routers enjoy the same level of protection.
With a StrongVPN account, customers have the ability to choose which server location they want, even down to the specific city. This type of personalized, user-friendly service is also seen with their unlimited server switching, as well as the ability to have up to six simultaneous connections on different devices. StrongVPN supports Mac, Windows, iOs, Android, and even multiple routers, which is a huge plus. 
Mobile VPNs are designed and optimized to ensure a seamless user experience when devices are switching networks or moving out of coverage. It generally has a smaller memory footprint, and because of that, it also requires less processing power than a traditional VPN. Therefore, it enables your applications to run faster while the battery pack is able to last longer.
Prices – PureVPN is currently offering three subscription plans: 1-month, 1-year, and 2-year deals. The cheapest subscription deal is the 2-year plan which you can avail for only $2.49/month. It is always a pleasure to have a great product being sold for so cheap. A new addition that I found during PureVPN review was its bumped-up 31-day money-back guarantee, which means that you can even go for a refund if you are not satisfied with it.
At fast vpn service all reviews are carried by an experts and knowledgeable team who have a lot of experience in the vpn field. We provide unbiased reviews which help you in selecting the fast vpn provider and through our concentrated effort we filter the best one for you. Every feature of different vpn providers is clearly researched and then highlighted in the review with explanation categorically.
Challenge Handshake Authentication Protocol (CHAP) is an encrypted authentication mechanism that prevents transmission of the actual password on the connection. The NAS sends a challenge, which consists of a session ID and an arbitrary challenge string, to the remote client. The remote client must use the MD5 one-way hashing algorithm to return the user name and a hash of the challenge, session ID, and the client’s password. The user name is sent as plain text.
In short, it's time to start thinking about protecting your personal information. That's where virtual private networks, or VPNs, come in. These services use simple software to protect your internet connection, and they give you greater control over how you appear online, too. While you might never have heard of VPN services, they are valuable tools that you should understand and use. So who needs a VPN? The short answer is that everyone does. Even Mac users can benefit from a VPN.
