Ultrasurf VPN Review & Test in 2024: Before You Buy, Is It Worth It?

Ultrasurf VPN Review & Test

Ultrasurf VPN Review Ultrasurf is a free website unblocker that offers basic anti-censorship services by using encryption and providing a unique IP address through a proxy server. Initially, it was created to help Chinese internet users bypass strict censorship regulations. However, it should be noted that Ultrasurf may censor content deemed offensive. Although lacking advanced security features, customer support, and an easy-to-use interface, Ultrasurf still remains an effective tool for those seeking a free option that does not require payment or credit information.

It is important to remember that the company can disclose user data to comply with US laws; therefore, users must ensure their online activities are legal and secure when using this tool. Furthermore, while Ultrasurf may unblock websites and provide anonymity, it does not offer complete privacy protection. Users should be aware of the limitations when using this service and consider additional security measures such as VPNs (Virtual Private Networks) if necessary.

Ultrasurf is a free tool that offers encryption for HTTPS traffic but not regular HTTP traffic. It has a logging policy that retains data for up to 30 days, which may not be ideal for some users. The lack of server locations outside the US and slow speeds can also be a deterrent. However, Ultrasurf performs satisfactorily in unblocking most legal geo-restricted websites after thorough testing of speed, security, device compatibility, gaming, streaming, and torrenting. During tests from the US, it worked seamlessly with local services like Disney+ but could not unblock Netflix.

Although the speed results were mediocre, the connection was stable and consistent.If Ultrasurf does not meet your requirements, vpnMentor provides more reviews to help you find the best tool for your needs. It is important to select a VPN service that aligns with your internet usage patterns and provides robust security features while delivering fast speeds. Additionally, you should consider server location coverage and compatibility with different devices before choosing a VPN service.

Ultrasurf VPN Pros and Cons

Like any VPN service, Ultrasurf VPN has its pros and cons. Here are some of the advantages and disadvantages of using Ultrasurf VPN:


  • Ultrasurf VPN is completely free to use, which makes it an attractive option for budget-conscious users.
  • The service is easy to use, with a simple interface that even beginners can navigate.
  • Ultrasurf VPN has a large network of servers in over 50 countries, which ensures fast and reliable connections.
  • The service has a strict no-logs policy, which means that it doesn’t keep any records of your online activities.


  • Ultrasurf VPN doesn’t offer as many features as some of its competitors, such as split tunneling or a kill switch.
  • The service may not work with some websites or services that have strong anti-VPN measures in place.
  • Ultrasurf VPN doesn’t offer dedicated IP addresses or support for P2P file sharing.
  • The service may be slower than some of its competitors, especially during peak hours.

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

While Ultrasurf is supported only in the US, it can still be used to access certain streaming services such as Disney+ and YouTube. However, it may not be the best tool to use if you’re looking to unblock other popular streaming platforms like HBO Max, Netflix, Amazon Prime Video, and Hulu. These services have implemented measures that block Ultrasurf’s IP addresses, making accessing them through this tool difficult. It’s worth noting that while Ultrasurf may not work with some streaming sites, it still provides a secure way to browse the internet and protect your online privacy.

Ultrasurf was originally created to bypass ISP censorship and not specifically for streaming platforms. This means that its primary function is to help users access restricted content by getting around ISP throttling. While it can be used for streaming, the quality of streaming with Ultrasurf is average due to its tendency to slow down internet connections. It is important to note that the tool’s creators may have different intentions than those who use it for streaming purposes. Therefore, when choosing a VPN or proxy tool for streaming, it is crucial to consider factors such as speed, reliability, and security to ensure the best possible experience.

Worked With: Disney+ and YouTube

After testing Ultrasurf from within the US, it was found that the tool was surprisingly effective when used with Disney+. Users reported no issues while accessing their accounts, and the streaming quality was satisfactory. There were some reports of a brief wait time for movie titles to load, but playback was smooth with no buffering issues.Overall, Ultrasurf provides an uninterrupted streaming experience on Disney+; however, the initial wait time may vary depending on connection speed.

It should be noted that since Ultrasurf only has servers in the US, users can only access the Disney+ US library. If you are outside of the US and enable the proxy, you will be blocked from accessing your usual content. Therefore, it is recommended to use a VPN service that provides access to multiple countries’ libraries if you travel frequently or want more viewing options.

Ultrasurf is a tool that can be used to bypass internet censorship and restrictions. To test its performance with YouTube, I conducted a YouTube performance test. Despite being geo-restricted in China, Ultrasurf worked seamlessly with YouTube. I played a video to check the streaming quality and buffering speeds, and it worked smoothly at 480 pixels. However, when I increased the quality to 720p and 1080p, there were some lags due to an overall reduction in connection speed, so it’s best to set the quality based on your internet speed. Despite this issue, Ultrasurf still allowed full functionality of YouTube without any delays or interruptions.

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

I managed to access my Netflix US account using Ultrasurf, but the loading time was not ideal. It took about thirty seconds for content to load, and then an additional two minutes for the movie screen to appear after selecting a title. Following the slow loading times, an error message appeared on Netflix. After experiencing this multiple times with different titles, I concluded that Ultrasurf is not effective for streaming on Netflix due to its slow speed. Therefore, if you are looking to stream high-definition movies and shows on Netflix, we recommend checking out our list of the top VPNs for Netflix.

When I used Ultrasurf to access the Amazon Prime Video website, the movie titles failed to load despite multiple attempts. Initially, a “Streaming Delay” pop-up appeared followed by an error message after about 30 seconds. This indicates that while Ultrasurf can function with Amazon Prime Video, there may be issues with loading and buffering. Additionally, as Ultrasurf only provides US servers without the option to choose, I couldn’t conduct further tests on a different server. Similarly, Ultrasurf was unable to stream any titles on HBO Max, and the Max homepage took a long time to load during my test. It’s important to note that the performance may vary based on the internet connection speed.

Ultrasurf encountered difficulties in loading titles on HBO Max. While the platform did not explicitly provide a reason, it appears to be blocking the connection on the back-end. As a result, I have determined that Ultrasurf is not suitable for streaming on HBO Max.Similar issues were observed on Hulu, where the website functioned after a 20-second loading delay. However, the movie titles continued to load for about a minute without progressing in buffering, ultimately leading to an error message.Hulu exhibited slow loading times and also presented an error message, similar to the experiences with Netflix, Amazon Prime Video, and HBO Max. This could potentially be attributed to the WebRTC leaks that expose the VPN, as demonstrated in my security tests.

As a side note, the Ultrasurf team recommends using WebRTC blocking extensions with Chrome for additional security. Despite testing two WebRTC leak-blocking extensions, leaks still occurred (more details in the security section). As a result, it was determined that such browser extensions would not resolve the issues with the aforementioned streaming services. Additionally, Ultrasurf utilizes a limited number of IP addresses for web server connections. Given the strictness of streaming services towards proxies and the lack of IP address variation, one should not expect Ultrasurf to be compatible with most streaming services. Please note: vpnMentor opposes the violation of copyright laws and advocates for using VPNs for secure and private online activities, not for illegal purposes. Always adhere to the guidelines of streaming services and local regulations when using a VPN.

Speeds — Slow and Inconsistent

Ultrasurf, an anti-censorship tool, is known for its slow and inconsistent speeds. During testing, there were significant fluctuations in loading times, with some pages not even loading at all. While there were short bouts of good speed, lengthy wait times were common. It’s important to note that since Ultrasurf is a free service, unmatched performance should not be expected.In the past, Ultrasurf faced server overload due to increased traffic from Iran. This led to frequent server crashes which was confirmed by the team on their official website. It’s possible that the current slow speeds are due to overloaded servers resulting from high traffic from countries with strict internet censorship laws. Despite these challenges, Ultrasurf remains a valuable tool for those seeking to bypass censorship and access restricted content online.

According to Freedom House, Ultrasurf’s user base grows during significant social events in China, including the 2003 SARS outbreak and the 2008 Tibetan uprising. It is likely that the recent COVID-19 pandemic has also led to increased demand for Ultrasurf’s services. To evaluate its impact on my browsing experience, I conducted a speed test. First, I ran an Ookla speed test without using Ultrasurf, but it was unable to find an optimal server for the test. Next, I connected to a US server using Ultrasurf and tried the FAST speed-testing service. However, the results were not satisfactory. While Ultrasurf may provide users with access to censored content, it appears that its impact on browsing speed may be limited.

Although my upload speed stayed relatively constant, there was a notable decline in the download speed and latency. I consistently noticed slower browsing and increased loading times on websites that would normally load quickly.
I have summarized the results of my internet speed test 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)

Ultrasurf, while effective at bypassing internet censorship and privacy protection, can have a significant impact on internet speed. This can make it less than ideal for data-intensive activities like streaming or torrenting. However, it remains an excellent option for those looking to browse the web anonymously and access restricted content. It is important to note that factors such as network speed and server location can also affect Ultrasurf’s performance. Therefore, it is recommended to test its performance before using it for any specific purpose.

Are Ultrasurf’s Speeds Fast Enough for Gaming? No

Based on my speed tests, Ultrasurf’s US servers displayed a considerable latency, indicating that the tool is not suitable for gaming. Moreover, it is important to note that Ultrasurf is not a conventional VPN but rather a browser-focused tool specifically designed to bypass geo-restrictions on browsers such as Internet Explorer or Chrome. While it can be used for browser-based gaming, I wouldn’t recommend it since Ultrasurf did not pass all of my WebRTC leak tests, which might jeopardize your online privacy and security. It’s essential to use a VPN service with adequate security measures in place if you want to ensure complete protection while browsing or gaming online.

Ultrasurf is not a suitable tool for gaming due to its slow speed and lack of security features. Gaming requires high-speed internet connectivity, which Ultrasurf cannot provide. Moreover, online gaming involves sensitive data such as login credentials, in-game purchases, and personal information that require secure connections. Unfortunately, Ultrasurf lacks the necessary security measures to protect this information from potential cyber threats. Therefore, it is not recommended to use Ultrasurf for online gaming purposes.

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

Ultrasurf’s server locations only offer US-based IP addresses, with no disclosed information about the number of servers in the US on their official website. Despite attempts to contact their customer support, it was found that their email-based support is notably slow. The lack of server locations and proper customer support could be attributed to Ultrasurf being a free internet circumvention tool with limited funds.

During testing, it was observed that the assigned IP address changes periodically. It’s important to note that having servers in multiple locations can significantly enhance a VPN’s performance and reliability. More server options allow users to select a closer one for faster connection speeds and prevent overcrowding for better network stability. Despite these limitations, Ultrasurf remains a popular choice for those in need of an easy-to-use and free VPN service.

Ultrasurf has been noted to be consistent over shorter time periods, indicating that it offers multiple IP addresses. Nonetheless, users are unable to select a specific IP address as the tool automatically assigns one. Furthermore, there are suggestions that Ultrasurf utilizes cloud services to update its IP addresses, thereby improving its geo-unblocking capabilities. This functionality allows users to access content that is restricted in their region by concealing their actual location and assigning them an IP address from a different location.

The automatic assignment of IP addresses has both positive and negative aspects – it provides anonymity and unblocks content, but it also presents security risks because the user has no control over the specific server they are connected to. Additionally, Ultrasurf does not provide any encryption or security protocols, leaving online activity vulnerable to cyber threats. Therefore, when using Ultrasurf or any other proxy tool, it is crucial to prioritize online safety and implement additional security measures such as Virtual Private Networks (VPNs) or firewalls for enhanced protection.

Security — Not the Best

Ultrasurf is a free product designed primarily to bypass internet censorship by utilizing secure HTTPS end-to-end encryption. It relies on TLS/SSL protocols and does not offer the option to choose between them. However, it does not encrypt regular HTTP internet traffic, unlike a full-fledged VPN. Ultrasurf does not incorporate advanced security protocols or features such as OpenVPN, IKEv2, WireGuard, Shadowsocks, split tunneling, Tor over VPN, or double VPN, which are found in paid options. As a result, it lacks the security capabilities of a typical VPN and instead relies on security through obscurity (STO) design, which is inherently unreliable.

Ultrasurf, a popular software used for bypassing internet censorship and accessing restricted content, has been found to lack the ability to enhance online privacy or serve as an online security tool. Even after undergoing various security tests, a WebRTC leak test revealed the user’s public IP address. While Ultrasurf does acknowledge this vulnerability, it recommends the use of additional WebRTC blocking extensions to improve online security, particularly when using Ultrasurf in Incognito mode.

It is important for users to be aware of these limitations when using Ultrasurf and to take additional measures to protect their online privacy and security. This may include using a reputable VPN service that provides strong encryption and advanced security features. It is also advisable to regularly update your device’s software and antivirus programs and to avoid accessing sensitive information while using Ultrasurf or any other similar software.

In order to test this assertion, I installed two WebRTC blocking extensions known as WebRTC Control and Easy WebRTC Block, reconnected Ultrasurf, and conducted the tests once more. However, there were no noticeable changes, and my original public IP address was still visible in the WebRTC leak test. Therefore, it is possible that WebRTC blocking extensions do not improve the security of Ultrasurf.Upon conducting leak tests while connected to Ultrasurf, I have concluded that Ultrasurf is not sufficiently reliable in terms of security.

It is not an open-source project, which means that its claims cannot be verified through community audits.Furthermore, I observed the absence of an automatic kill switch option. In the event of an internet connection loss, your information may be vulnerable to leakage upon restarting. This is a crucial security feature that Ultrasurf lacks.Additionally, Ultrasurf lacks a camouflage mode like legitimate VPNs. The camouflage option prevents websites and services from detecting that a VPN or proxy is being used. Consequently, it is not possible to conceal the fact that traffic is being encrypted while connected to Ultrasurf.

Privacy — Safe but Not Reliable

Ultrasurf claims that it is not involved in managing or modifying users’ data in any way. Instead, it provides uncensored access to content by tunneling internet traffic through a secure encrypted tunnel. However, the company emphasizes that Ultrasurf should not be considered an online security tool as it does not increase the privacy of internet users. For improved privacy, the company suggests using privacy tools alongside Ultrasurf.One of the benefits of using Ultrasurf is that it does not ask for personal information such as credit card details or name from its users. This sets it apart from paid VPNs and other censorship circumvention tools that do require such information. It’s important to note, however, that while Ultrasurf provides some level of anonymity and access to restricted content, it may not be effective in protecting user privacy against more advanced forms of online surveillance.

Nevertheless, it records a substantial level of user engagement on its site. This encompasses:

  • 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 states that it will not reveal any personally identifiable information to third parties except when required by law or for the company’s protection. However, a 2012 report by a Tor investigator claims that the Ultrasurf team admitted to disclosing information to the US Government at one point. The report also highlights significant vulnerabilities, particularly concerning data retention. For example, it states that Ultrasurf logs connections of all users in a manner that infringes on privacy, making it possible to link the logged data to individuals even after they have stopped using Ultrasurf.

Ultrasurf has not publicly disclosed further details about its encryption specifications and data logging process, despite responding to the report. Due to its questionable logging policies and location in the United States, where data retention laws are stringent, Ultrasurf is not considered reliable. Additionally, Ultrasurf censors a significant amount of online content that it deems objectionable, such as pornography, gore/shock websites, and other harmful content.

Torrenting — Slow and Unsafe

Ultrasurf is a browser-based content-unblocker and does not limit torrenting activities. However, users can only torrent through the web versions of BitTorrent or Utorrent. It should be noted that Ultrasurf is not the best option for security and privacy when it comes to torrenting. Its primary function is to circumvent geo-restrictions on internet content.While using Ultrasurf for torrenting, it is crucial to be aware of its limitations and potential risks.

This tool may not provide adequate protection against WebRTC leaks, which can compromise user data security. Moreover, torrenting is prohibited in many regions, and using Ultrasurf for this purpose may also lead to legal consequences. Therefore, it is advisable to exercise caution while using this tool for torrenting activities and consider alternative options for better security and privacy protection.

Ultrasurf, a popular online privacy tool, has clearly stated on its official website that it does not endorse or encourage any illicit or illegal activities online. It is important to note that torrenting is illegal in many countries due to issues related to copyright infringement. Neither Ultrasurf nor vpnMentor promotes any kind of abuse or misuse of the tool, and we strongly recommend checking local laws before considering torrenting.

It is essential to use online privacy tools like Ultrasurf responsibly and within the bounds of the law. While these tools can help protect your online privacy and security, they should never be used for illegal activities such as downloading copyrighted content without permission. It is always best to stay informed about local laws and regulations related to online activities and use these tools accordingly.

Does Ultrasurf Work in China? Yes

Ultrasurf is a tool that provides unrestricted internet access to users in mainland China where internet censorship is rampant. The tool was explicitly designed for this purpose and has been widely used by Chinese citizens to circumvent the government’s strict internet restrictions.Many users have reported no issues when setting up Ultrasurf, but slow internet speeds are a common complaint. Despite this, given that it’s a free tool, Ultrasurf performs well in China. It has become an essential tool for Chinese citizens who wish to access the internet freely and without restrictions.

Ultrasurf has gained immense popularity worldwide, with millions of users from over 180 different countries. While it is widely used in China, it is also a preferred choice for internet users in countries like Syria and Iran, where the government imposes strict censorship laws. Ultrasurf’s ability to bypass internet restrictions and provide unrestricted access to online content has made it a popular tool for those who value online privacy and freedom of speech. With its user-friendly interface, Ultrasurf has become a go-to solution for individuals seeking an easy-to-use and effective way to access restricted content without being monitored by their governments or ISPs.

Simultaneous Device Connections

Ultrasurf is a free tool that provides users with privacy and security while browsing the internet. It is available for download on multiple devices, and there are no restrictions on the number of devices it can be used on. Unlike other tools that require creating an account or purchasing a package, Ultrasurf offers its services completely free of charge. Additionally, users can run the tool independently on each device without any need for synchronization or linking accounts. This makes it a convenient and hassle-free solution for those looking to protect their online activities from prying eyes.

Device Compatibility — Works on All Major Devices

Ultrasurf is a free proxy tool available for Windows, iOS, Android, and Chrome. However, it does not have a separate extension/client for Linux, Mac, or Firefox. It also lacks support for routers. The Windows client supports Internet Explorer and Mozilla Firefox, but note that the Windows Defender may flag the Ultrasurf Windows client as CoinMiner malware upon download. This issue has been reported by several sources on the internet. Ultrasurf’s website acknowledges this issue and claims that some anti-virus software companies misclassify their tool as malware or Trojan. It is important to exercise caution when downloading and using Ultrasurf.

As per the Ultrasurf team, anti-virus software detects it for suspicious activity because Ultrasurf bypasses censorship and encrypts data. However, the technical reasons for this have not been disclosed by the Ultrasurf team. If you are concerned about your device’s security, the Chrome extension may be a safer option. I also tested it and found it to function similarly to the regular Windows client. Additionally, I downloaded the iOS version from the App Store, where it is labeled as “Ultrasurf VPN.” Given that Ultrasurf does not function as a VPN in the true sense, I believe this labeling is somewhat deceptive.

Ultrasurf’s iOS app interface is designed to be sleek and simple, much like the Windows client and Chrome extension. The app’s ease of use allows users to connect to the internet anonymously with just one tap. In comparison to the Android app, both versions have a similar design that prioritizes usability on-the-go with limited customization options. While this can be seen as a strength in terms of accessibility, it may also be viewed as a limitation for those seeking more personalized settings. Overall, Ultrasurf’s iOS app offers a streamlined experience for users looking to browse the internet securely and privately.

It can be downloaded and executed without the need for registration, making it convenient for users to copy the executable file to a USB drive and connect securely by plugging it into any Windows PC. Although the user interface has a vintage look reminiscent of Windows XP days, it is functional and serves its purpose well. The simple design also makes sense economically since Ultrasurf is entirely free to use.In addition to the desktop app, Ultrasurf offers Android and iOS apps, as well as a separate Chrome extension. All of these can be downloaded directly from the Download section on their official website.

Ultrasurf is a free tool, so you can use all its features without paying anything. There are no paid subscriptions, no limits on bandwidth, and no trial periods. It’s completely free and doesn’t require registration. However, it doesn’t provide high-level protection and security features. Although it’s free to use, it’s not a reliable option for user privacy and full internet anonymity. According to reports, Ultrasurf logs user activity and may share it with authorities if required. For more details, refer to our security section.

Although Ultrasurf is a free VPN service, it lacks the advanced features and capabilities of paid VPNs. For instance, the speed and server count may not be as impressive as those of premium VPN services. Security and privacy are also areas where Ultrasurf falls short when compared to its paid counterparts. Moreover, the user interface (GUI) may not be as user-friendly or intuitive as that of other VPNs. Paid VPNs also offer advanced options such as split tunneling and multi-hop connections that are not available on Ultrasurf. While Ultrasurf may be a viable option for basic browsing needs, users who require more robust protection may need to consider investing in a paid VPN service.

Reliability & Support

Ultrasurf serves its intended purpose of content unblocking but also censors content deemed offensive, including adult and illegal websites. Users find the support to be inconsistent and prolonged, with only email support available. However, the response time for emails is often lengthy. I tested their support by sending an email to their official address but have not received a reply yet, leading me to conclude that Ultrasurf’s customer support is very slow. Additionally, the support is exclusively offered in English, creating a language barrier for non-English speakers.

In general, users will primarily depend on the information provided on Ultrasurf’s website and online blogs. Many common questions are addressed in the FAQ section of its official website. Additionally, the team has established a user center containing extensive information and a helpful manual. Furthermore, users can access numerous guides on YouTube to assist themselves.

Bottom Line

Ultrasurf is a freeware tool that is worth experimenting with. It allows full access to an anti-censorship tool without any cost. Although it does not have all the features of high-security VPNs, it offers convenient access to the majority of geo-restricted websites (excluding those intentionally censored by the Ultrasurf team). Despite being free, Ultrasurf has slow speed and a questionable data logging policy. It is not recommended to depend on it for high-bandwidth activities due to the lack of a seamless experience guarantee.

In addition, it’s important to note that Ultrasurf is not designed as an online privacy or security tool, as emphasized by the Ultrasurf team on their official website. Therefore, it’s best to have limited expectations regarding its security and privacy features.

  • 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
