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.

As we said, KeepSolid VPN Unlimited is also good value, if you’re prepared to dig deep. Paying £76.45 for three years use is equivalent to paying £2.12 a month, or, if you’re really made of money, then £152.92 will net you a lifetime subscription. The standard monthly price of £7.64 doesn’t compare as well, but £45.88 for 1 year (equivalent to £3.82 a month) is slightly better than others.

All that being said, we currently name TorGuard as the fastest VPN service. It doesn't take the top spot in all of our tests, but has remarkably low latency and had the best performance in the all-important download tests. Fittingly, it offers many add-ons such as dedicated IP addresses that, along with its speed, will appeal to the BitTorrent users it is designed to protect.


If users are still double-minded about using NordVPN, take a look at this complete privacy analysis. We connected to a stealth server in Hong Kong and then performed a test via IPLeak.net. The results showed that the VPN was successful in hiding our true US location. It displayed a Hong Kong IP Address for our IPv4 and public address. The DNS address also showed that we were connected to a single server located in Hong Kong.
A recent FTC complaint alleges Hotspot Shield has been hijacking HTTP requests for e-commerce sites and directing users to affiliate sites instead. If true, that would be an unforgivable abuse of users’ trust. Hotspot Shield is already known for the shady practice of inserting tracking cookies and advertisements into users browsers whenever they use the service, which clearly defeats the purpose of using a VPN. Hotspot Shield is primarily a free service but also has a premium tier. We suggesting keeping your distance from both.
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.
Because few VPN companies offer live support, we appreciate when they at least provide easy-to-follow resources on their websites. Detailed setup guides with step-by-step instructions are available for every platform IVPN supports, and it breaks down troubleshooting advice into language that’s easy to understand. ExpressVPN also has clear, helpful support articles, but other services aren’t as straightforward. It’s harder to find the right information on TorGuard’s support site, and its articles aren’t as novice-friendly. If you need to submit a ticket for a specific problem, you can expect a quick response from all the companies we tested—IVPN and TorGuard both responded to us in minutes, and PIA took the longest at one day. ExpressVPN was the only one of our finalists that offered tech support over live chat. (Other companies provide live chat only for sales and signup support.)
This is also a good way to provide support for more than one family member on a single subscription. Generally, there's no good reason for a VPN provider to allow less than two or three connections. If your provider only allows one, find another vendor. We gave extra points in our VPN directory to those vendors who allowed three or more connections.

Once on the public internet, those packets travel through a bunch of computers. A separate request is made to a series of name servers to translate the DNS name ZDNet.com to an IP address. That information is sent back to your browser, which then sends the request, again, through a bunch of computers on the public internet. Eventually, it reaches the ZDNet infrastructure, which also routes those packets, then grabs a webpage (which is actually a bunch of separate elements), and sends all that back to you.
However, network performance is another thing entirely. First, keep in mind that if you're using a VPN, you're probably using it at a public location. That Wi-Fi service is likely to range in performance somewhere between "meh" and unusable. So, just the fact that you're remotely working on a mediocre network will reduce performance. But then, if you connect to a VPN in a different country, the connection between countries is also likely to degrade network performance.
Due to licensing restrictions, iOS developers previously couldn’t implement OpenVPN connections directly inside their applications. Since that changed in mid-2018, a few providers, including IVPN and PrivateInternetAccess, have added native OpenVPN support to their apps. This makes a secure connection on any Apple device much easier than the old method that required a clunky third-party application and complicated connection profiles. Though we haven’t done performance tests on any updated iOS apps yet, our limited use of the updated IVPN app worked without any problems. Going forward, we wouldn’t consider a VPN provider that doesn’t include native OpenVPN support on iOS.

However, you've got no choice but to run TunnelBear's client software (unless you use Linux), which may concern some privacy-minded users, and there's no option to set up TunnelBear connections on routers or other devices. Last but not least, this tiny Canadian firm is now owned by U.S. antivirus giant McAfee, which may mean TunnelBear is subject to U.S. search warrants.
NordVPN’s customer service is also quite good. They offer 24/7 live chat support directly through their website and many support guides and tutorials. Right now NordVPN is extending the 75% discount price exclusively for three-year plans. All subscriptions come with a 30 day money-back guarantee, allowing you to try the service risk free. [Learn more >]
In many cases, each of these offices also have LANs. But how do the LANs connect? For some very specialized solutions, companies lease private lines to connect the offices. That can be very expensive. Instead, most companies opt to geographically connect separated private LANs over the public internet. To protect their data, they set up VPNs between offices, encrypting the data as it traverses the public internet.

When you connect your computer (or another device, such as a smartphone or tablet) to a VPN, the computer acts as if it’s on the same local network as the VPN. All your network traffic is sent over a secure connection to the VPN. Because your computer behaves as if it’s on the network, this allows you to securely access local network resources even when you’re on the other side of the world. You’ll also be able to use the Internet as if you were present at the VPN’s location, which has some benefits if you’re using pubic Wi-Fi or want to access geo-blocked websites.


We used to advise people to do banking and other important business over their cellular connection when using a mobile device, since it is generally safer than connecting with a public Wi-Fi network. But even that isn't always a safe bet. Researchers have demonstrated how a portable cell tower, such as a femtocell, can be used for malicious ends. The attack hinges on jamming the LTE and 3G bands, which are secured with strong encryption, and forcing devices to connect with a phony tower over the less-secure 2G band. Because the attacker controls the fake tower, he can carry out a man-in-the-middle attack and see all the data passing over the cellular connection. Admittedly, this is an exotic attack, but it's far from impossible.
If you use Intrusion Detection System (IDS) technology, you should know that if the IDS machine is between the Internet and the VPN concentrator that decrypts the encrypted packets (e.g., on a demilitarized zone—DMZ—network), it won't be able to detect intrusion activity that occurs between VPN-connected machines. Most IDS sensors match packet payloads to a database of intrusion signatures so that they know when to flag something as suspicious. If the packets are encrypted, they'll look like gibberish to the IDS machine. If you want your IDS machine to be able to monitor network traffic from VPN connections, make sure you place the IDS machine behind the VPN concentrator so that the IDS machine checks the traffic after the VPN concentrator decrypts it. You can't use an IDS on a software VPN, which operates directly from one VPN host to another.

Trust and transparency issues are the foremost concerns in choosing a great VPN, and if a service doesn’t have enough locations to be useful to you, all the security features won’t make a difference. But after those concerns have been satisfied, we recommend that most people use connections based on the OpenVPN protocol, because of security flaws and disadvantages in the PPTP and L2TP/IPsec protocols. (Experienced users may consider IKEv2, but because it has its own debated pros and cons, we ruled it out.) Though AES 128-bit encryption is fine for most purposes, we prefer services that default to the more-secure 256-bit encryption and still offer good performance.
We spent more than 130 hours researching 32 VPN services, testing 12, interviewing the leadership of five, and consulting information security and legal experts. We found that a VPN shouldn’t be your first step toward online security, but for protecting your info on public Wi-Fi (and in some other cases), IVPN is the most trustworthy provider that offers fast, secure connections and easy setup.
Once you are in the digital world, you must remember that without using the VPN, your IP address and location are available to the entire Internet. Moreover, every device you use has a personal IP-address, through which you can be easily found, as well as all your online activity, can be tracked. When using VPN, you get different solutions including anonymity, maximum protection of your data, the ability to bypass geo-blocking, censorship and bothersome advertising. The virtual private network server to which you are connecting encrypts your traffic and assigns your device a new IP address. Thus, in the online world, you will be in complete safety. Hackers and third parties will not be able to track your traffic, data or determine your actual location. 

It reduces the monthly pricing all the way down to $3.29 by giving you an amazing 72% discount! Best part of all: you have a 30-day refund guarantee available. This means, if you do not feel comfortable using the VPN, you can always request for your money back. Once you subscribe to NordVPN though, you gain access to a huge list of 4452 servers in 62 countries worldwide. They come in handy for unblocking VoDs or engaging in P2P.

TorGuard was consistently one of the fastest services we tested. When we averaged three tests performed at different times of the week with Internet Health Test, TorGuard was the fastest service when connecting in the UK and Asia, the second fastest in the US, and the third fastest in Central Europe. OVPN was the next most consistent, but that company’s small network doesn’t have any servers in Asia, and it ranked fifth in the UK. Our top pick, IVPN, was the third most consistently fast after TorGuard and OVPN. However, we tested with each app’s default settings—since we expect most people won’t change them—and TorGuard’s default 128-bit encryption gives it an advantage in speed tests over VPNs that default to 256-bit encryption, as most services do. Still, we think 128-bit encryption is fine for most people who prioritize speed, and TorGuard’s consistency makes it a good value as our budget pick.

Windscribe  offers unlimited device connections. Yes you heard that right! The reason is that unlike the others above on this list, it doesn't offer unlimited data. So you're limited by bandwidth and data, not by devices. You get 10GB every month, and there's a free plan also but that only allows one device. There are apps for Windows, Mac and iOS but not Android, and the service also offers browser add-ons with useful features such as ad-blocking. Short range performance (to US sites) is good, but we noticed lag with transatlantic connections. However, if you’re looking to protect the data from a whole bunch of devices - an office, perhaps, or just a smart home - the support for unlimited connections is a real stand-out feature.


Since it takes research to find out if a VPN service has a history of good or bad behavior, we’ve done the legwork to find the best VPN out there. In order to win our seal of approval, the service has to protect online privacy; allow you to keep anonymity; offer a good variety of locations from which to direct your traffic; offer fast, reliable performance; and provide an easy-to-use interface.
Multi-hop cascades + NeuroRouting – Perfect Privacy gives you the ability to create multi-hop VPN cascades across up to four different servers in the network. This protects you against the possibility of a rogue data center logging traffic, targeted monitoring, and other threat scenarios. Additionally, the NeuroRouting feature dynamically routes all traffic through multiple hops in the server network, and can be used with any device (explained more here).
Unlike ExpressVPN, CyberGhost has a section of its interface dedicated to streaming. Version 7 has specialty servers for over 50 streaming platforms, with everything from movies to music in the mix. Each server is optimized for a particular platform based on its location. For example, Channel 4 is optimized on a U.K. server and Netflix is optimized for the U.S.

Many VPN services also provide their own DNS resolution system. Think of DNS as a phone book that turns a text-based URL like "pcmag.com" into a numeric IP address that computers can understand. Savvy snoops can monitor DNS requests and track your movements online. Greedy attackers can also use DNS poisoning to direct you to bogus phishing pages designed to steal your data. When you use a VPN's DNS system, it's another layer of protection.
If HTTP browsing is a postcard that anyone can read as it travels along, HTTPS (HTTP Secure) is a sealed letter that gives up only where it’s going. For example, before Wirecutter implemented HTTPS, your traffic could reveal the exact page you visited (such as https://thewirecutter.com/reviews/best-portable-vaporizer/) and its content to the owner of the Wi-Fi network, your network administrator, or your ISP. But if you visit that same page today—our website now uses HTTPS—those parties would see only the domain (https://thewirecutter.com). The downside is that HTTPS has to be implemented by the website operator. Sites that deal with banking or shopping have been using these types of secure connections for a long time to protect financial data, and in the past few years, many major news and information sites, including Wirecutter and the site of our parent company, The New York Times, have implemented it as well.
ExpressVPN is also one of the best VPNs for streaming. Whether you are using a VPN with Kodi or streaming Netflix with a VPN, ExpressVPN offers great apps for streaming devices and high-capacity bandwidth for HD videos and downloads. Their customer service is also top-notch, with 24/7 live chat support and a 30 day money-back guarantee with all subscription plans. [Learn more >]
IPSec supports several different enciphering algorithms. The most commonly used algorithm, Advanced Encryption Standard (AES), is widely acknowledged as one of the strongest algorithms available for data encryption. With a minimum key length of 64 bits, AES is strong enough for almost any commercial application. Some vendors' IPSec implementations use the Data Encryption Standard (DES) or Triple DES (3DES) ciphers. DES, whose 40-bit key has been cracked, is generally considered a weak algorithm for all but the lowest security levels. 3DES fixes DES's problems by using the algorithm three times and providing an effective key length of 168 bits. Note that if your VPN solution supports only one algorithm, any devices you add in the future must use that algorithm as well.

Netflix blocking paying customers might seem odd, but it's all about regions and not people. Just because you paid for Netflix in one place does not mean you're entitled to the content available on the same service but in a different location. Media distribution and rights are messy and complicated. You may or may not agree with the laws and terms of service surrounding media streaming, but you should definitely be aware that they exist and understand when you're taking the risk of breaking them. Netflix, for its part, lays out how that it will attempt to verify a user's location in order to provide content in section 6c of its Terms of Use document.

For those who are unaware, net neutrality is the much-discussed concept that ISPs treat web services and apps equally, and not create fast lanes for companies that pay more, or require consumers to sign up for specific plans in order to access services like Netflix or Twitter. Federal net neutrality rules would ensure that the internet effectively continues to operate the way it has for its entire existence.

DNS Leaks are incredibly dangerous for users who regularly stream pirated content or engage in P2P/Torrenting. However, when you sign up with NordVPN, you can feel assured that there are no dangers of your DNS leaking out. Nothing will reveal your true identity or location. As you can see, the results below show that there is only a single DNS server detected. It does not indicate or hint towards our real location!
What that means in practice is that VPNs are fine for bypassing geo-blocks, for protecting your online banking and for keeping business communications free from interception. However, if you’re using the internet to fight repressive regimes or to do anything else that could attract the attention of the authorities where you live, a VPN is not a magic wand that’ll make you invisible.

Users gain access to a huge list of 2000+ servers in 140+ countries and 180 locations worldwide, multiple security protocols (PPTP, L2TP, SSTP, IKEv2, OpenVPN & the revolutionary Stealth protocol), and simultaneous connections on more than five devices at the same time. In addition to this, PureVPN even goes the extra mile in protecting your data by offering IPV6 and DNS Leakage.
Selecting a suitable provider involves more than just exploring the pricing, support, features, and servers availability. You need to make sure that you receive maximum security online. Luckily, you do get what you pay for with CyberGhost. We conducted a WebRTC Leak Test on the provider by connecting to a server in Germany.As you can see, the public IP Address is that of a German Server. The local IP is also different than the one from our local ISP.
They’re Based in Romania – A Safe Jurisdiction, if they do collect some of your personal data, (say logs – it’s aggregated into a combined form and represents a collection of the mass or sum of all VPN.ac users). Besides possibly being on an altogether different server than your selected surfing point from, they won’t share it with any other countries. Rest assured…
VPN services are offered to give you the mandate to surf the Internet with ease of knowing you are safe. Today, VPN is more popular with people who are looking to have anonymity and keep their activities in secret. Most of the people have gone to the extent of having top VPN app that will guarantee them online security and conceal their online activities. VPN services are essential for keeping malicious people and hackers from accessing your information during your Internet session. There are frequent cases of people getting their personal information in the wrong hands or either unsuspecting hackers accessing your Wi-Fi device either at work or home. In simple terms, VPN is the remote server that encodes and routes all received and sent information. After going through the VPN server identification and successfully passing the authorization process, its algorithms hide your identity and your real geolocation.
When it comes to servers, more is always better. More servers mean that you're less likely to be shunted into a VPN server that is already filled to the brim with other users. NordVPN, Private Internet Access, and TorGuard currently lead the pack with well over 3,000 servers each—NordVPN is at the forefront with 5,130 servers. But the competition is beginning to heat up. Last year, only a handful of companies offered more than 500 servers, now it's becoming unusual to find a company offering fewer than 1,000 servers.
ExpressVPN’s “#1 Trusted Leader in VPN” claim may be a bit difficult to prove, but the service offers a compelling list of features nonetheless. It also constantly tries to make consistent improvements in speed and simultaneous streaming capabilities, and with support for all major platforms (Windows, MacOS, Android, etc.), you won’t need to worry about compatibility. ExpressVPN shows up on a number of “best VPN” lists, and so its relatively high prices are justified.

A representative from the VPN Company informed that they are already under review. They have gone through negotiations with three different independent audit companies. We received no exact dates for the audit being available to the public. However, the process can take anywhere from a few weeks to two months During our conversation, the representative also revealed details about releasing “Transparency Reports” for their service.

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.
The last virtual private network we are going to review for being of the most secure ones, is VyprVPN. The service is based in Switzerland, but some discrepancies are found in the VPN’s Story page. With around 70+ worldwide server locations, a L2TP/IPSec protocol implementation and OpenVPN support, VyprVPN has what to offer to the table of the most secure VPNs.

Think about all the times you’ve been on the go, reading emails while in line at the coffee shop, or checking your bank account while waiting at the doctor’s office. Unless you were logged into a private Wi-Fi network that requires a password, any data transmitted during your online session could be vulnerable to eavesdropping by strangers using the same network.

Since we last tested VPNs, we've given special attention to the privacy practices of VPN companies and not just the technology they provide. In our testing, we read through the privacy policies and discuss company practices with VPN service representatives. What we look for is a commitment to protect user information, and to take a hands-off approach to gathering user data.
