Each protocol on your computer operates on its own port (like a channel). This way your computer knows which incoming data belongs to which program. The problem is all data has to go through your router first. If your router has alot of devices connected to it, it may not be sure which data/ports to forward to each specific computer. This can cause data bottlenecks and slower speeds.
Although HideMyAss!’s logging policy states that the network does, in fact, keep data logs, it is important to mention that these logs are for diagnostic purposes only, meaning they record your connect/disconnect activities as well as bandwidth usage – not the websites you’ve visited nor the data that’s been transferred! Without getting too technical, it simply means your internet service provider (ISP) won’t know what you’ve downloaded or streamed, nor whom you’ve emailed or the content of your correspondence.
Anonymity and Privacy: In like manner to a web proxy, the VPN service is also a hit for customers who wish to gain a measure of anonymity on the internet and also protect their identity and privacy. However, unlike a web proxy, the VPN service affects all applications on your computer, not just your web browser. This, therefore, enables users to protect their entire internet connection and not just their web browser traffic.
One basic test for a VPN service is to check how long a VPN client takes to connect to a VPN server and get online. For our 2018 reviews, we installed each vendor's VPN client software on an HP EliteBook x360 1020 G2 laptop running Windows 10, an iPad mini and a Samsung Galaxy S8 Android phone. (In 2017, we used a Lenovo ThinkPad X1 Yoga notebook, an Apple MacBook Air, a Samsung Galaxy S6 phone and the iPad mini.) We used each device with each VPN service we tested.
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.

Mullvad is not that easy to use, with a bare-bones desktop interface and, unlike every other VPN service we've reviewed, no mobile client apps. (You do get instructions on how to manually set up OpenVPN apps.) This service's network speeds were far from great in our tests, and it's fairly expensive, with no discount for paying yearly instead of monthly.
Various countries around the world restrict access to one type of online content or another. Social networks, games, chat apps – even Google itself is not beyond the reach of censorship. In addition, many academic institutions and workplaces enable firewalls to limit access to websites for various reasons. These range from seeking to increase productivity to restricting inappropriate content.

Cator promoted the tool in online forums[3] and it was featured on the front page of Digg.[2][5] After attracting more than one thousand users, Cator incorporated ads.[2] HMA! did not take any venture capital funding.[3][2] It generated about $1,000 - $2,000 per month while the founder went to college to pursue a degree in computer science.[2] In 2009, Cator dropped out of college to focus on HMA! and added a paid VPN service.[3][2][1] Most early HMA! employees were freelancers found on oDesk.com.[2] In 2012, one of the freelancers set-up a competing business.[3] HMA! responded by hiring its contractors as full-time employees and establishing physical offices in London.[3][5]

The service prides itself with airtight security achieved with the help of its split-tunneling feature which lets you route some of your device or app traffic through the VPN while other devices or apps maintain direct access to the internet. This is an especially useful feature when it comes to torrenting as you can choose to protect only the torrent client, while all your other online activities remain unaffected.
Well I mostly use Zenmate Chrome extension if I need to unblock site or streaming normally its free and fast. I have used IPVanish VPN and its really great. IPVanish offer fast speed, data encryption, protocols, features, multiple IPs, gaming support etc. If you guys need suggestion and recommendation for best VPN you can visit bestvpnservice.com for premium VPN provider reviews and discount details.
If you’ve played with torrents before you’ll know it’s a hobby that requires a degree of patience. Large files can take hours, days or even weeks to download. If your VPN connection drops for even a moment during the download, your IP address could be exposed, revealing your true identity. If you’re serious about protecting yourself when torrenting, the most important feature to look out for is a ‘kill switch’. A kill switch is part of your VPN's software that, when enabled, will make sure your IP address isn't exposed by instantly killing your connection if your VPN connection fails.
Torrents get a bad rap, and if we’re honest, that’s for good reason. Using torrents is the number one way to download pirated material including movies, TV shows, music, and games. But that’s not all there is to torrenting. It’s a very efficient way to download legitimate software such as Linux distributions and authorized content from sites such as BitTorrent Now.
Which means you’re wide open to all sorts of advertiser schemes. They could even charge you more for your favourite subscription services once they know how much you love it! As well as this there’s the access to your private messages, adult content viewings and entire browsing history — all open to tracking, storing and selling by your ISP when you don’t have a VPN service.
Despite leaks and disclosures about government data-collection efforts in recent years, it’s hard to determine the exact reach of current operations and how vulnerable encryption technologies like VPNs are to those efforts. Given the more immediate threats to security and privacy from other avenues, none of the experts we interviewed highlighted government data collection as the foremost reason for most people to get a VPN. A VPN could help prevent some types of passive data collection—and a trustworthy VPN certainly can’t hurt—but there’s no guarantee against government tracking.
IPVanish is one of the most recognisable names among all the VPN services out there. They've been going for years and if you've read about VPNs in the past you've probably seen some of their ads! IPVanish certainly isn’t going after the budget market here but it's still a bit cheaper than ExpressVPN. Like Express, IPVanish doesn’t offer a free trial (although there is a seven day money back guarantee if the service doesn’t live up to your expectations). It promises to be the world’s fastest VPN, with more than 40,000 IP addresses, 850 servers in 60 countries, unlimited peer to peer sharing and up to five simultaneous connections. That's certainly a bonus over ExpressVPN which only offers three connections at a time - IPVanish could be the better option for you if you want to get the whole family on one plan, for example. There’s a no logging policy, too, which means the service isn’t gathering stacks of data about what you’re doing.
Hide me VPN Download for both Mac and Windows is the finest application for hiding IPs. It can conceal a greater part of your projects and matches IP out of hackers, stop fraud, and shield against hacker interruptions. You can operate all the above functions with a single click. Your IP address may connect your online exercises straight for you. Hide.me VPN License Key also gives protection to your internet identity by changing your IP address into our own host’s IP.
I've been using PIA for awhile. The only problem I have had with it is on torrents being uploaded. I like to keep up on what's popular in the UK and I've been pinged by my ISP a couple times for having (unknown to me) files in the uploading torrent that are flagged by a takedown filter. Coming down has had no issues. I suspect that the problem lies with the seed torrent going out to other people, but I don't understand how the file is traced back to me if it is going through the VPN.
The service supports torrenting through its zero logs policy. It supports PPTP, Open VPN and L2TP connections, with each going up to 256 bits except for PPTP. To further increase security, IPVanish uses shared IPs, making it even more difficult to identify users. This also ensures that even the vendor could not furnish agencies with your information even if it wanted to.

While I appreciate the emphasis on real-world applications for VPNs, I think it's better to just have a button to quickly get a person online safely. Most people might not be familiar with the benefits of using a VPN, or understand what the distinction is among the three modes. (Truth be told, I'm not sure I do, either.) A big, simple button similar to NordVPN or TunnelBear, with other options under the hood, seems like the best approach. Still, it's far friendlier and easier to use than, say, Private Internet Access, which is little more than a window to start your connection.
CyberGhost adheres to a no-logs policy, uses 256-bit AES encryption with perfect forward secrecy, and has a kill switch on its desktop clients. An app-specific kill switch is buried in the settings, dubbed “app protection,” which will only cut off internet to specified programs, e.g. a torrent client. CyberGhost Pro scored well in our speed tests and can even unblock US Netflix and Amazon Prime Video.
One of the major reasons why people recommend VPN over proxies is that torrent clients reveal your true location and leak information while using proxy. Although, the latest version of torrent clients are designed to do a better job at this but I personally don’t trust proxy services. They can be unreliable and fail to protect you while using torrents. I would rather stick with a VPN just because of this. Currently, I am using PIA (Private Internet Access) but I have also heard good reviews about PureVPN.
Do you want to watch your favorite sports teams? A VPN for streaming sports is your solution. The lucrative nature of sports licensing means that television channels are forbidden from showing games that are outside of their region or license. VPNs like Express VPN are a great way to watch your favorite teams securely and privately because you will be able to stream games at high-quality and top speed. A simple VPN download can hence save the day for you.
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.
VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels, and VPN users must use authentication methods -- including passwords, tokens or other unique identification procedures -- to gain access to the VPN server.
I definitely agree with your list, tried few of your picks and really liked them. Though, I myself got the best results with Surfshark so I have a subscription with them now. I guess it’s because their servers are not crowded at all yet so speed is really surprising and stable. I’m just hoping they add a server in Canada soon though I’m all set and ok using New York servers until then.
Almost all VPN services now offer a dedicated macOS client. These are sometimes not quite as fully featured as their Windows siblings, but are often all but identical. In general, what makes a great VPN for your Macbook or Mac Mini is exactly the same as what makes a good VPN for any other system. Please check out our Best VPNs for Mac for our top macOS recommendations.

There are many, many VPN providers, and Mozilla can’t recommend any specific service. PC World, however, has reviewed a ton of VPN services and ranked them all. The winner? Currently it’s Sweden-based Mullvad, which doesn’t even keep your email address. Instead, it auto-generates an anonymous account number when you create an account. The service is reportedly fast and ultra secure. Speedy services CyberGhost and TunnelBear also ranked highly, and NordVPN was called out as a great way to watch blocked U.S. Netflix shows and other services while abroad. FoxyProxy, by Mozillian Eric Jung, offers VPN service in more than 68 countries.
A company representative told me that a full 225 of the 286 server locations offered by Hide My Ass are virtual servers. Only 61 of the server locations are hardware, and 450 of Hide My Ass's 876 servers are virtual. That's far beyond other services. NordVPN, Private Internet Access, TunnelBear, IPVanish, and TorGuard only use physical infrastructure for their server locations.

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.
You can use free browser extensions to prevent the most common ways that websites and ad networks track your browsing activity and gather information for marketing profiles. But if you’re trying to leave as few tracks as possible online, a VPN can add an extra layer of privacy by preventing tracking based on your IP address (the unique identifier for your computer or home network that makes it possible for websites and services to send information back to you).
ExpressVPN is both the best all-round VPN and our pick for torrenting, due to its rock solid reliability for both speed and privacy. No other VPN offers such consistently fast speeds across its entire network – up to 201Mbps down and 163Mbps up with very low latency on local connections is ideal for P2P activity. If you also like to stream then uninterrupted access to Netflix, BBC iPlayer and other popular services is another big selling point.
To narrow the hundreds of VPN providers to a manageable list, we first looked at reviews from dedicated sites like VPNMentor and TorrentFreak, research and recommendations from noncommercial sources such as That One Privacy Site and PrivacyTools.io, and user experiences and tips on various subreddits and technology-focused websites like Lifehacker and Ars Technica.

At its simplest level, a Virtual Private Network is connection between your computer and a remote data server (or remote network). All data transferred between your computer and the server is encrypted (encoded) using extremely advanced encryption algorithms to make sure nobody who intercepts your data can read it or see what you're doing online (your ISP is an example).


As a bonus, access to Netflix and other popular services is rock solid thanks to dedicated streaming servers. The apps are innovative but there are easier-to-use alternatives available. Customer support is friendly and helpful with fast live chat and email responses. At $2.75 on an 18-month plan though, it’s incredible value and easy to overlook the shortcomings.
In the domestic latency tests, Hide My Ass had an impressively small impact, increasing ping time by only 42.9 percent. TorGuard VPN had the best score in this category, actually reducing latency by a slight 6.7 percent. Results were less rosy in the international latency tests, where Hide My Ass increased latency by 400.3 percent. TunnelBear had the best score in this round, increasing latency by 270.3 percent.
I also after a year of paying month by month, I bought a 1 year subscription from one their promos. I then discovered they were also charging me for my monthly subs. Getting my money back was fairly ordinary. As soon as I disputed the monthly costs they suspended my account. In the end I got my monthly subs back, but lost the balance of the yearly sub - luckily it had been a good promo.

Despite some of the drawbacks, ZorroVPN is an 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.
Security is second to none with NordVPN. Its kills switch feature always monitors traffic between devices and the VPN servers. If for some reason, the data stream breaks, the kill switch will automatically terminate the connection, ensuring that your traffic is protected from prying eyes. Also, a DNS leak feature changes your DNS to point to the VPN server, ensuring that hackers cannot steal data from your default DNS.
Increasingly, mobile professionals who need reliable connections are adopting mobile VPNs.[33][need quotation to verify] They are used for roaming seamlessly across networks and in and out of wireless coverage areas without losing application sessions or dropping the secure VPN session. A conventional VPN can not withstand such events because the network tunnel is disrupted, causing applications to disconnect, time out,[31] or fail, or even cause the computing device itself to crash.[33]
While I found flaws with my personal VPN, I was intrigued to carry out further research. I was astonished to find an in-depth report containing statistical data of IP leaks found in multiple VPNs for Android. According to the report 84% of Android VPN torrent applications, leaked IP addresses which would make one consider the whole purpose of the application.
Our table and reviews detail both where each service is based and whether it retains any connection logs. However, logging isn’t the be-all and end-all of VPN security. We’ve restricted ourselves to testing services from reputable companies with a proven track record, but it’s impossible to truly know how much faith can be put in any organisation’s claims about their logging policy.
While a VPN can aid privacy and anonymity, I wouldn’t recommend fomenting the next great political revolution by relying solely on a VPN. Some security experts argue that a commercial VPN is better than a free proxy such as the TOR network for political activity, but a VPN is only part of the solution. To become an internet phantom (or as close as you can realistically get to one), it takes a lot more than a $7 monthly subscription to a VPN.
Our mission is to provide anyone who wants it with access to a safe and private internet connection. We are the only VPN service that exerts full control over its entire infrastructure. From network architecture and customer support, to our physical hardware and software development, every part of IPVanish is owned and operated by us at IPVanish. This independent style of operation enables us to maintain an airtight zero-logging policy. No other VPN service can match that level of security when they’re borrowing network components.
It’s also fast with impressive 830+ server locations, which makes it an excellent choice for P2P file-sharing, online gaming, and HD streaming. There are no annoying bandwidth caps here, and you can connect to Netflix US, BBC iPlayer, or France’s Canal+ if you wish – there’s a server for every need. The double encryption will understandably slow things down.
Some VPNs offer “split tunneling,” which routes all traffic through your VPN except specific services or sites that you allow. For example, you might want to send your Web traffic through your VPN but stream Netflix on your fast, domestic connection. But these types of rules are complicated to implement without also leaking other important information, and we didn’t assess how effective they were in practice.

When you download torrent, your IP address has been shared with all the other users who are downloading and seeding the torrent file. The same happened when you are uploading the torrent file. This IP address information can be used by hackers. This is also very common in case of P2P file sharing network because it is your IP address which has been used by torrent clients like uTorrent to provides you the torrent file.


Sadly, I engaged PIA, the number one rated and paid a "great price" for a 3 year service only to findout that dur to a recent SMTP abuses they no longer can be used when using Microsoft servers. So, all of my outbound email is rejected from Microsoft Servers due to this policy. In itself, fine, but as I enrolled in this service and while setting up the servie at no time was this mentioned nor, prior to a May 15 issue, was this a problem.
— In  an effort to improve transparency and trustworthiness in the VPN industry, the Center for Democracy and Technology released the answers it had received from five different VPN providers — ExpressVPN, IVPN, Mullvad, TunnelBear and VyprVPN — regarding a questionnaire the CDT had earlier distributed. The questionnaire has to do with corporate ownership and accountability, data logging and security practices. The CDT hopes to get similar answers from other VPN service providers.
If you don’t mind doing a little extra tinkering in a more complicated app to save some money, we recommend TorGuard because it’s trustworthy, secure, and fast. TorGuard is well-regarded in trust and transparency; it was also the fastest service we tried despite being less expensive than much of the competition, and its server network spans more than 50 locations, more than twice as many as our top pick. But TorGuard’s apps aren’t as easy to use as IVPN’s: TorGuard includes settings and labels that allow extra flexibility but clutter the experience for anyone new to VPNs. And unlike IVPN, TorGuard doesn’t natively support OpenVPN connections on iOS, making it a significantly worse choice on Apple devices than it is if you use Windows, ChromeOS, or Android.
To get a sense of the impact from each service, I use the Ookla internet speed test tool. This test measures latency, upload speed, and download speed, so those are the three areas that I focus on as well. (Note that Ookla is owned by Ziff Davis, which also owns PCMag.) I first run a series of tests without the VPN active, drop the lowest and highest results, and then average what remains. By comparing those results to ones taken when the VPN is active, I can find a percent change between the two. I then perform this comparison again, but using a VPN server in Australia and an Ookla test server in Anchorage, Alaska to see how the VPN performs when connecting to distant servers.
We summarize the protocols above, and look at them in detail in VPN Encryption: The Complete Guide. Although L2TP/IPsec is fine for most purposes, we only really recommend OpenVPN and IKEv2. OpenVPN is very secure if properly configured. Indeed, Edward Snowden’s documents showed that even the NSA can’t crack well-implemented OpenVPN. It is also supported by almost every provider.  But it is relatively slow. The newer IKEv2 is much faster and is considered secure, but has not been battle-tested in the way that OpenVPN has. It is not as well supported at present, although it is increasingly popular with providers thanks to its speed advantages over OpenVPN.

In the upload tests, Hide.me was in the with the bulk of the pack, reducing upload speeds by 5.6 percent. IPVanish had the best results for these tests, reducing upload speeds by only 2.9 percent. The international upload tests are all clustered around the same place, and Hide.me's 98.4 percent reduction in upload speeds is quite normal. The best score goes to Private Internet Access, which reduced upload speeds by 97.3 percent.
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.
A NAT Firewall may offer robust benefits but users have reported frequent issues while using NAT for torrents and P2P file sharing. In addition, NAT firewall can significantly reduce your download speed. However, this issue can be resolved by Port Forwarding, which allows torrent traffic to pass through a specific port in NAT Firewall. The best VPN services mentioned in this guide offer port forwarding, that will allow you to download torrents faster from anywhere in the world.
HMA provide real-time auto-updatable database of free working IP:PORT public proxies.Publlic proxy lists are checked from the largest database of public open proxies in real-time with up to the minute auto-updatable results 24/7. You may use these proxies in any application with proxy settings, including web browsers, chat clients,whois checkers, automated applications, etc
ExpressVPN attempts to build trust in other ways, even without a public face. Court records from 2017 demonstrate that when Turkish authorities seized ExpressVPN servers in the country looking for information, they found nothing of value, as promised by ExpressVPN’s no-logging policy. ExpressVPN also highlights initiatives such as open-source leak-testing tools, developer content about how the company implements different technologies, and support for the efforts of OpenMedia and the EFF. The ExpressVPN representative even offered to arrange a confidential call between our writer and the owners of the company. However, without being able to discuss their identities or learn about other senior leadership, we believed that wouldn’t have been enough to change our recommendation, so we declined. In the end, trust is such a crucial part of deciding which VPN to use that we had to pass on ExpressVPN.

PIA is an established name in the VPN world and is among the cheapest of the well-known offerings, claiming to be the "highest quality for the lowest price." Designed for torrenting, PIA doesn’t monitor or restrict any connections including peer-to-peer file sharing and can be used with any torrenting client without the annoyance of being blocked or throttled.

A powerful VPN service, SaferVPN is very useful in hiding users’ IP addresses. It also allows access to blocked websites or safely share information. Privacy is also ensured as the service uses high security protocols. It offers a unique Automatic Wi-Fi Security feature which instantly activates a secure and encrypted VPN connection as soon as someone’s device connects to an unsecured Wi-Fi connection — automatically protecting them from public Wi-Fi threats. Likewise, it features single-click applications for Windows, Mac, iOS, Android and Chrome.
I do these tests twice. The first time, I use a server located close to my physical location. This puts the emphasis on speed and performance, and is likely indicative of how most people will use the service. Then, I perform the same tests while connected to an Ookla test server in Anchorage, Alaska, and a VPN server in Australia. The vast distances involved act as a stress test of the service.

A lot of people started using a VPN to evade geo-restrictions. But despite its forbidden benefits to users outside the US, a VPN is a great tool that can protect you and enhance your online experience over the internet by providing you with sufficient security and privacy. When it comes to selecting the best VPN, you have plenty of choices. There are many cost-effective VPN options, and all of them will vary in monthly offerings. Choosing the best VPN is easier once you narrow down the competition. The best indication of a good VPN service provider is that they have the right security and the right support in place for you.

We tested NordVPN and found that it works well with Netflix and other streaming services that block most other VPNs. It is compatible with all devices, does not retain logs, and offers a 30-day money-back guarantee (it's real, we checked). With a price so low, it's no wonder NordVPN is the most popular VPN out there, used by technology experts all around the world.


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.
VPNs also cloak your computer's actual IP address, hiding it behind the IP address of the VPN server you're connected to. IP addresses are distributed based on location, so you can estimate someone's location simply by looking at their IP address. And while IP addresses may change, it's possible to track someone across the internet by watching where the same IP address appears. Using a VPN makes it harder for advertisers (or spies, or hackers) to track you online.
HideMyAss manages your browsing data and activity. It encrypts your data using one of their encryption protocols to mask information from hackers and snoopers online. It also allows you to access blocked websites from your location. It allows you send and receive data directly to one of their servers, dodging any restrictions or limitations set on your locality. It is like you are accessing the internet on the place where HideMyAss server is located, liberating you from any internet censorship that hinders your ability to access any website that you want.
From a broader perspective, there are several factors that demand the use of a solid VPN while torrenting. First of all, you do not want your privacy to be compromised during torrenting. Specifics of your personal information, your IP address, your location, and even the browser you are using should stay with you only. Then, there is the question of speeds. Depending on the nature of the VPN you are using, you could feel like there is a rise or drop in the speed of downloads and uploads (learn more about this in our pros and cons to VPNs).
The Pirate Bay is certainly the biggest torrent site in the world and one of the most controversial to ever exist. It has been blocked in at least 28 countries and has survived battles with some of the world’s most powerful governments. This site is over 15 years old, however, and as a result ranks high in terms of reliability. It allows users to torrent movies, TV series, books, applications, games and music. Our research shows that the majority of torrents on TPB are movies and TV shows.

Online piracy laws are a little fuzzy in India. A slew of news reports from 2016 suggested that even viewing certain web pages or torrent files (not the copyrighted content itself) was enough to penalize netizens with heavy fines and jail time. This is not true, however; the rumor arose from a poorly-worded warning from Indian ISPs that appeared when users tried to access blocked sites.

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.

Even with extra protection, unique features about your browser may be enough for other parties to collate data about you. For example, browser fingerprints—based on screen size, browser plugins, fonts, time zones, and more—can identify a single user even without cookies or IP addresses. (Check out the EFF’s Panopticlick test tool to see if your browser’s fingerprint is unique and thus trackable. It probably is.)
