Ultrasurf VPN Review 2024: Read This Before Buying

Our Score: 3.7/10
Ranked 182nd out of 198 VPNs
Shummas Humayun Updated on 11th July 2024 Former Cybersecurity Researcher

Ultrasurf is one of the most popular 100% free website unblockers that assign you a unique IP address through a proxy along with a decent level of encryption. So, technically speaking, it is not a VPN. Instead, Ultrasurf recognizes itself as a simple anti-censorship tool.

The main idea behind Ultrasurf was to provide regular internet users in mainland China with a free and reliable tool to circumvent strict internet censorship. Ironically though, Ultrasurf mentions that it may still censor content that it deems offensive. The definition of “offensive” might vary from user to user. So, in that sense, Ultrasurf might also be doing exactly what it claims to fight against.

Unlike actual VPNs, Ultrasurf does not offer 24/7 customer support, advanced security and privacy features, and an intuitive user interface. But for a free tool, it gets the job done well. Since it is a free tool, it does not ask for payment or credit information. Still, to comply with US laws, the company states that it may hand over user data to any concerned parties.

I found out that Ultrasurf only encrypts HTTPS traffic and not regular HTTP traffic. Also, their logging policy is not too comprehensive and suggests that data may be retained for up to 30 days.

The US is the only server location it offers, and so you cannot choose a different one. This lack of servers and slow speeds might be a deal-breaker for some people.

To figure out whether this tool is worth it, I thoroughly tested its multiple aspects, including speed, security, device compatibility, gaming, streaming, and torrenting.

For a free tool, the results were satisfactory, and I must say — Ultrasurf can unblock most legal geo-restricted websites, some of them successfully, others not so much — mostly due to the speeds it offers. During my tests from the US, it worked with my local services like Disney+, but not Netflix. While the speed results were not impressive, the connection was stable and consistent.

If you decide that Ultrasurf is not the tool for you, visit vpnMentor for more reviews, and you'll find the one that suits you best.

Streaming — Works With Disney+ US and YouTube but Fails to Work With Netflix, Amazon Prime Video, HBO Max, and Hulu

When I tested Ultrasurf from the US, the only region where it's supported, I found that it worked with Disney+ and YouTube. Despite this, Ultrasurf did not perform well with HBO Max, Netflix, Amazon Prime Video, and Hulu. These services appear to have safeguards against Ultrasurf's IP addresses.

Some sources say that Ultrasurf's creators have designed their tool to bypass ISP censorship rather than for use with streaming platforms. As a result, streaming quality with Ultrasurf is average, mainly because it tends to slow down the internet connection.

Worked With: Disney+ and YouTube

Testing Ultrasurf from within the US, its effectiveness with Disney+ was surprisingly good. I had no issues using my account as normal. While there was a brief wait of about 30 seconds for movie titles to load, the streaming quality was quite satisfactory, and I experienced no buffering issues during playback.

A screenshot of streaming on Disney+ with UltrasurfStreaming on Disney+ with Ultrasurf

Overall, you can enjoy uninterrupted streaming via Ultrasurf on Disney+. Though, the initial wait time can vary among users depending on the connection speed. Once you get past that, it’s all well.

However, since Ultrasurf only has servers in the US, you can only use it with the Disney+ US library. If you're outside of the US and you enable the proxy, you’ll be blocked from accessing your local Disney+ content.

Next, I decided to run a YouTube performance test. After all, it is among the biggest content streaming websites out there, and yet it is still geo-restricted in China. So, I was specifically interested in figuring out if Ultrasurf will seamlessly work with YouTube.

I had no issues using YouTube without any delays or lags. I played a video to test the streaming quality and buffering speeds and, to my surprise, it was buttery smooth at 480 pixels.

A screenshot of streaming a YouTube video with UltrasurfStreaming a YouTube video with Ultrasurf

However, when I increased the quality to 720p and 1080p, I did notice some lags due to an overall reduction in connection speed. So you should set the quality depending on the speed. Rest assured though, YouTube is fully functional with Ultrasurf.

Doesn’t Work With: Netflix, Amazon Prime Video, HBO Max, and Hulu

While I was able to open my Netflix US account with Ultrasurf, the loading time was somewhat less than ideal. It took around thirty seconds for content to load. After choosing a title, I waited for an additional two minutes for the movie screen to show up. After waiting, I received an error message.

Screenshot of the error message that appeared on Netflix while connected to UltrasurfAfter the slow loading times, an error message appeared on Netflix

I considered the possibility of this being a one-time error. So, I repeated the process over 5 times with multiple titles. However, the pattern was the same. Hence, I concluded that Ultrasurf is pretty much useless when it comes to streaming on Netflix.

While it technically works with Netflix, the slow speed makes Ultrasurf less than ideal for streaming, and hence, you will struggle to establish a connection with Netflix servers in the first place.

If you want to stream high-definition movies and shows on Netflix, we suggest you check out our list of the top VPNs for Netflix.

While the Amazon Prime Video website opened when I was connected to Ultrasurf, the movie titles did not load even after multiple attempts. First, a Streaming Delay pop-up appeared, and after about 30 seconds, an error message showed up:

A screenshot of the “Streaming Delay” notification and the error message that popped up when I tried to stream on Amazon Prime VideoA “Streaming Delay” notification and an error message popped up when I tried to stream on Amazon Prime Video

So, Ultrasurf can certainly work with the Amazon Prime Video website, but you might have difficulty with loading and buffering. As for me, the titles did not load in the first place, which defeats the purpose. And since Ultrasurf only offers US servers that you can’t choose from, there was no room for further tests on a different server.

Just like Amazon Prime Video, Ultrasurf fails to run any titles on HBO Max despite successfully working with the website. In my test, it also took forever to load the Max homepage. The performance might vary depending on the internet connection speed.

A screenshot of the error message that appeared on HBO Max while connected to UltrasurfUltrasurf failed to load titles on HBO Max

Of course, HBO Max does not explicitly state the reason. But at the back-end, it seems to be blocking the connection. Based on this, I concluded that Ultrasurf is not suitable for streaming on HBO Max.

The results on Hulu were pretty much the same. The website was functional after a loading delay of 20 seconds. However, the movie titles kept loading for around a minute without any progress in the buffering. After a minute of loading to no avail, I received an error message.

A screenshot of the error message that popped up on Hulu while connected to UltrasurfLoading times were slow on Hulu, and an error message appeared too

Just like Netflix, Amazon Prime Video, and HBO Max, Hulu also didn’t work with Ultrasurf. This could be due to the WebRTC leaks that reveal the VPN, as indicated in my security tests.

On a side note, the Ultrasurf team suggests using WebRTC blocking extensions with Chrome for extra security. However, I tested two extensions designed to block WebRTC leaks, yet leaks still occurred (more on this in the security section). Based on that, I concluded that such browser extensions would not help fix the issues with the streaming services listed above.

Furthermore, Ultrasurf only uses a limited number of IP addresses to connect to the web servers. Since streaming services are often strict with proxies and the like, and there is not enough variation in the IP addresses, one should not expect Ultrasurf to work with most streaming services.

Important: The vpnMentor team stands against the violation of copyright laws. We support the use of VPNs to secure and privatize online activities, not for illegal purposes. It's important to always follow the terms of streaming services and abide by local laws while utilizing a VPN.

Speeds — Slow and Inconsistent

Ultrasurf's speeds are slow and inconsistent. While testing this anti-censorship tool, I experienced significant fluctuations in the loading times. Amidst lengthy wait times, there were short bouts of good speed. At times, some pages failed to even load at all.

However, since this is a free anti-censorship service, one should not expect unmatched performance.

At one point in the past, Ultrasurf had to struggle with overloaded servers due to increased traffic from Iran. This caused the servers to crash often, which was also confirmed by the team on the official website. Hence, the current slow speeds could be a result of overloaded servers due to high traffic from countries that have tough internet censorship.

At the same time, Freedom House reports, “Ultrasurf’s user base expands every time a significant social event takes place in China, such as the 2003 SARS outbreak or the Tibetan uprising in 2008.” Perhaps the recent COVID-19 outbreak could have also caused an overload on the Ultrasurf servers due to a high user base.

Nevertheless, I decided to quantify my experience with the help of a speed test. First, I ran an Ookla speed test on my regular connection, with Ultrasurf turned off. These were the results:

A screenshot of my speed test results before using UltrasurfMy speed test results before using Ultrasurf

Then, I turned on the Ultrasurf tool, and it automatically connected to a US server. Though, despite waiting for a considerable period, speed test by Ookla could not find an optimal server for the speed test, as shown in the shot below:

A screenshot of the error message by Ookla while I was connected to UltrasurfA message by Ookla notifying me to try to connect to a server again

I then headed to another speed-testing service called FAST, which is powered by Netflix. Unlike the speed test by Ookla, Ultrasurf was able to establish a connection with FAST. Though, the speed results were a bit too underwhelming.

A screenshot of the speed test results while connected to UltrasurfSpeed test results while connected to Ultrasurf

While my upload speed remained somewhat the same, the download speed and latency took a significant hit. I consistently observed slower browsing and longer loading times on websites that would otherwise be quick to load.

Here is a summary of my internet speed test results on the US server:

Download speed (Mbps) 5.1 Mbps (86% decrease in speed)
Upload speed (Mbps) 6.1 Mbps (63% decrease)
Ping (ms) 364 ms (21 times higher than before)

Hence, I can conclude that Ultrasurf will significantly reduce your internet speed. This might make Ultrasurf less than ideal for streaming, torrenting, or other data-intensive tasks.

Are Ultrasurf’s Speeds Fast Enough for Gaming? No

My speed tests showed a very high latency on the US servers I tested, which means Ultrasurf's speeds aren't fast enough for gaming. Furthermore, it is not an actual VPN. It is a browser-focused tool with the sole purpose of bypassing geo-restrictions on your specified browser (either the default Internet Explorer or Chrome). You can still use it for browser-based gaming. But, I wouldn't suggest that since Ultrasurf didn't pass all my WebRTC leak tests.

So, gaming with Ultrasurf is totally out of the equation as the tool doesn't provide fast speeds and lacks security.

Server Network — One Server Location With an Unspecified Number of Servers

As far as the server locations go, Ultrasurf only offers US-based IP addresses. However, there is no mention of the number of servers in the US on their official website. I also tried reaching out to their customer support; however, their email-based customer support is notable for being painstakingly slow.

After all, it is a free internet circumvention tool. So, one can expect it to have limited funds, which explains the lack of server locations and proper customer support. Nevertheless, during my tests, I did notice that my assigned IP address changed every once in a while.

However, it remained consistent over shorter intervals. This suggests that Ultrasurf does offer multiple IP addresses. However, there is no way for users to choose any specific IP addresses. Instead, the tool assigns one automatically.

Along with that, some sources suggest that Ultrasurf uses cloud services to update its IP addresses, hence improving its geo-unblocking capabilities.

Security — Not the Best

Ultrasurf is a freeware product that is primarily meant for the circumvention of internet censorship.

This tool bypasses firewalls and censorship by using secure HTTPS end-to-end encryption. For that, Ultrasurf makes use of the TLS/SSL protocols (it does not give you an option to choose between either of these). However, according to the official website, the regular HTTP internet traffic goes through without encryption. In comparison, a full-fledged VPN would encrypt your entire device's traffic.

Unlike other paid options, UItrasurf does not use any advanced security protocols such as OpenVPN, IKEv2, WireGuard, and Shadowsocks that would otherwise significantly enhance a user’s security. Furthermore, it does not have features such as split tunneling, Tor over VPN, or double VPN.

In that aspect, it lacks the power of an actual VPN. All in all, it relies on security through obscurity (STO) design, which inherently is not reliable enough.

Regarding the low-security capabilities, the official Ultrasurf website itself states, “Ultrasurf does not increase your online privacy, and should not be considered or used as an online security tool.”

A screenshot of the security page on Ultrasurf’s websiteA screenshot of the security page on Ultrasurf’s website

To test Ultrasurf’s security, I ran a DNS, IPv6, and WebRTC leak test. While I did not observe any DNS or IPv6 leaks, the WebRTC leak test revealed my public IP address.

According to Ultrasurf, WebRTC leak is inevitable on Chrome as the browser does not let users disable WebRTC. However, the team suggests downloading additional WebRTC blocking extensions that can improve your security on the internet. This is particularly important if you want to run Ultrasurf in Incognito mode.

To test this claim, I installed two WebRTC blocking extensions called WebRTC Control and Easy WebRTC Block, reconnected Ultrasurf, and ran the tests again. Well, nothing really changed, and I could still see my original public IP address in the WebRTC leak test. So, WebRTC blocking extensions may not enhance Ultarsurf’s security.

A screenshot of the leak test results while connected to UltrasurfLeak test results while connected to Ultrasurf

Overall, I would not consider Ultrasurf as reliable enough in terms of security. It is not an open-source project, as a result of which no community audits can verify its claims.

I also noticed that there is no automatic kill switch option. So, in case you lose your internet connection, upon restart, your information might be susceptible to getting leaked. This is a must-have security feature that Ultrasurf lacks.

Also, it does not have a camouflage mode as actual VPNs do. The camouflage option makes it impossible for websites/services to know that you are using a VPN or a proxy. Hence, you cannot hide the fact that you are encrypting your traffic while connected to Ultrasurf.

Privacy — Safe but Not Reliable

The official Ultrasurf website states that it does not manage or modify your data in any way. All that Ultrasurf does is tunnel the internet traffic through a “secure encrypted tunnel” to provide uncensored access to content.

Ultrasurf also repeatedly suggests that it shouldn’t be treated as an online security tool because it does nothing to increase the privacy of internet users. The company further states, “If privacy is your primary concern, you may use privacy tools in combination with Ultrasurf.”

One good aspect of Ultrasurf is that it does not directly ask for users’ personal information such as credit card details, name, etc., unlike paid VPNs and other censorship circumvention tools.

However, it logs a significant amount of user activity on its website. This includes:

  • Public IP address
  • Pages viewed on their official website
  • Number of links clicked on their official website
  • The date and time of the visit
  • The webpage that links you to their website

Ultrasurf also mentions that it does not disclose any personally identifiable information to third parties unless it is in compliance with the law or for the company's protection.

However, I found a 2012 report by a Tor investigator, according to which the Ultrasurf team confessed to disclosing information to the US Government at one point.

Along with that, significant vulnerabilities have been pointed on in this report, especially those related to data retention. For instance, the report mentions that Ultrasurf logs connections of all users in a way that invades privacy. It would be easy to tie all the logged data to individuals, which can help identify even long after the individual stops using Ultrasurf.

Ultrasurf did respond to the report yet fails to publicly provide more information about its encryption specifications and detailed data logging process to this day.

Given the seemingly poor logging policies of Ultrasurf and the fact that it is based in the United States, where data retention laws are relatively strict, I would not consider Ultrasurf reliable.

With that, Ultrasurf also censors a big chunk of content on the internet that it deems offensive. This includes pornographic material, gore/shock websites, or other harmful and unsafe websites.

Torrenting — Slow and Unsafe

Ultrasurf does not limit torrenting activities. However, torrenting can only be done through the web versions of BitTorrent or Utorrent. That is because it is a browser-based content-unblocker.

But as far as torrenting goes, you should note that Ultrasurf is not the best when it comes to security and privacy. After all, it is primarily designed to circumvent geo-restrictions on internet content, and that is all.

Given the WebRTC leaks from my tests earlier, and because torrenting is restricted in many locations, I would not advise torrenting while connected to this tool.

With that, the Ultrasurf team states on the official website, “Ultrasurf is not intended to be used for illicit or illegal activities online, and Ultrasurf does not condone such activities.”

Note that torrenting is illegal in many countries because of issues related to copyright infringement. Neither vpnMentor nor Ultrasurf promotes any sort of abuse or misuse. So, we highly advise you to check your local laws before considering torrenting.

Does Ultrasurf Work in China? Yes

Yes, Ultrasurf works in China. It was explicitly made for users in mainland China to provide unrestricted internet access to the general public. After all, the government in China has set up strict internet censorship.

In numerous online forums, the majority of users mention they faced no challenges when setting up Ultrasurf. However, a common grievance among them is the sluggish internet speeds. Yet, considering it's a free tool, Ultrasurf demonstrates commendable performance in China.

The Ultrasurf team mentions on the website that there are “millions of users from over 180 countries.” Other than China, it is also popular among users in multiple other countries with strict censorship laws, including Syria and Iran.

Simultaneous Device Connections — 1

Ultrasurf is a free tool with no paid plans or packages. You can download it on as many devices as you want and run it on each device independently without making an account.

Device Compatibility — Works on All Major Devices

Ultrasurf is available for Windows, iOS, Android, and Chrome. This tool does not offer a separate extension/client for Linux, Mac, Firefox, and it doesn't support routers. With that, it also lacks a separate Internet Explorer extension, although the Windows client does support both Internet Explorer and Mozilla Firefox.

Note that when I first downloaded the Ultrasurf Windows client, my Windows Defender flagged the file as CoinMiner malware. I then found out that many sources on the internet flag the Ultrasurf Windows client for suspicious behavior. Regarding this, the Ultrasurf website states, “some anti-virus software companies misclassify UltraSurf as a malware or Trojan.”

According to the Ultrasurf team, anti-virus software flags it for suspicious activity because Ultrasurf circumvents censorship and encrypts data. However, technical details as to why it happens have not been provided by the Ultrasurf team.

If you are worried about your device’s health and security, the Chrome extension would be relatively safer to use. I tested that too, and it seemed to work just the same as the regular Windows client.

With that, I also installed the iOS version from the App Store, where it is listed as “Ultrasurf VPN.” Since Ultrasurf is not a VPN in the true sense, I find it somewhat misleading to title it as such.

Nevertheless, the interface of the iOS app is pretty neat and minimal, just like the Windows client and the Chrome extension. All it would take is a single tap to connect to the internet anonymously.

Here is a side-by-side comparison of Ultrasurf's iOS and Android applications:

A screenshot of Ultrasurf’s iOS and Android app interfaceUltrasurf’s iOS and Android app interface

As you can see, both applications have a similar design and are geared towards usability on the go, with minimal customization options available. Of course, that could be a strength as well as a limitation.

Installation & Apps

6.0

Set-Up & Installation — Quick and Easy

Ultrasurf's set-up and installation are pretty quick and easy. You can download it and directly execute it without registration. This makes it easy for users to copy the executable file to a USB drive and connect securely by plugging it into any Windows PC.

The vintage-looking interface might remind you of the Windows XP days. But that is fair because this tool is totally free for use. Hence, it is economically feasible to keep a simple design.

You can download the Android, iOS, and desktop apps (along with a separate Chrome extension) directly from the Download section of the official Ultrasurf website.

Pricing

8.8
Free VPN
$ 0 / month per month

Ultrasurf is a freeware tool, which means that you do not have to pay anything to enjoy its full benefits. There are no paid plans, no bandwidth limitations, and no trial either. It’s free for all, and that too, without the need for registration.

However, do not expect high-end protection and security features. While this tool is free, it is certainly not reliable for user privacy and complete internet anonymity. According to some reports, Ultrasurf keeps logs of user activity and could disclose them to the authorities if needed (check out our security section for more information on that).

Despite being completely free to use, Ultrasurf falls short in comparison to paid VPNs when it comes to factors such as speeds, server count, security, privacy, user interface (GUI), and advanced user options.

Reliability & Support

6.3

Ultrasurf is good for what it is intended to be — content unblocking. Still, it will censor any content that the team deems offensive, including many adult websites and/or websites containing illegal material.

According to most Ultrasurf users, the support of Ultrasurf is prolonged and almost inconsistent. This is a free tool that only offers email support. However, it can take many days for one to receive an email in response.

To test their response, I sent an email to their support's official email address. However, it has been a while, and I have not received a response yet. Based on that, I can conclude that Ultrasurf's customer support is painstakingly slow. Furthermore, the support is only available in English, resulting in a barrier for non-English speakers.

For the most part, users will have to rely on the information present on Ultrasurf's website and blogs online. For instance, plenty of common questions have been answered in the FAQ section on its official website.

The team has also set up a user center with detailed information and a help manual that might come in handy. With that, users can help themselves out by watching the countless guides available on YouTube.

The Bottom Line

Final Verdict

For a freeware tool, I would say that Ultrasurf is worth a try. You do not have to pay a single penny to get full use of this anti-censorship tool.

While it lacks some essential features of high-security VPNs, it provides quick and easy access to most geo-restricted websites (except those that the Ultrasurf team has intentionally censored).

Even though Ultrasurf is a free tool, its speed is slow, and the data logging policy is questionable. Therefore, it is not advisable to rely on it for high-bandwidth activities since a seamless experience cannot be guaranteed.

With that, also remember that this is neither an online privacy tool nor a security tool. The Ultrasurf team stresses this point on their official website. So, keep low expectations for its security/privacy capabilities.

  • Free to use anti-censorship tool with no bandwidth limitations
  • Easy set-up with no registration required
  • Works with Disney+ and YouTube
  • Works in China, Iran, Syria, and other regions
  • Features HTTPS encryption

FAQs on Ultrasurf

Is Ultrasurf safe?

Yes, Ultrasurf is essentially a safe tool. However, for some reason, their executable file got flagged as a coin-miner by my Windows Defender. Multiple sources complain about the same. However, the Ultrasurf team assures that anti-virus software wrongly classifies the executable as malware. For more information about Ultrasurf’s security, jump to the security section.

Can Ultrasurf work with Netflix?

No, Ultrasurf doesn’t work with Netflix. However, it is unclear whether slow connection speeds are to blame or because Netflix is blocking Ultrasurf's IP addresses. Take a look at the streaming section to see how Netflix and other streaming platforms performed with Ultrasurf.

Will Ultrasurf slow my speeds down?

Yes, Ultrasurf will considerably slow down your browsing speed. Hence, I suggest you only connect to it when you have to bypass geo-restrictions. For regular browsing where internet anonymity is not a concern for you, I suggest you keep Ultrasurf turned off. You can see my speed test results in the speeds section above.

Best but just for basic things

Because it's a VPN which is based in USA so it's difficult to trust on this 100%. My elders taught me that nothing is free in the world, if the service is free then you are the product to sale. My only one opinion to this VPN just use it for basics, it even doesn't need permission to access your device except "network connection", so it's literally safe but don't use for any sensitive stuff. By the way speed is great, without add and no use limit these elements make this one of the greatest free VPN of the world.
