Security and Encryption

The core objective of any VPN (Virtual Private Network) is to safeguard its user’s data by encrypting it and routing it through secure servers. In this context, let’s unpack the security features of Ultrasurf VPN.

Used Security Technologies

Ultrasurf VPN, with a decade-long presence in the market, primarily emphasizes bypassing censorship. The company relies on its proprietary encryption methods, which could be a double-edged sword. While unique encryption techniques can potentially prevent popular decryption algorithms from penetrating, the opacity of their protocols can raise doubts about their security efficacy.

Notably, the VPN utilizes industry-standard TLS (Transport Layer Security) encryption, which theoretically provides a solid security foundation. However, unlike its competitors that boast 256-bit AES encryption, Ultrasurf VPN is rather tight-lipped about its encryption strength, which is a cause for concern.

Given that security is paramount in a VPN, this lack of transparency makes it challenging to fully trust Ultrasurf VPN with sensitive data. So, should you trust your digital life to Ultrasurf? It’s a question that begs a clearer response from the company.

Used Encryption Technologies

Ultrasurf VPN uses a proprietary encryption system, which is uncommon in the VPN market. Many of its competitors use OpenVPN or IKEv2, which are time-tested and widely recognized as secure.

While proprietary technologies aren’t inherently a bad thing (think of Apple’s iOS, for instance), it becomes a potential issue when dealing with matters of security. We are left to rely on the company’s assurance that their proprietary encryption is secure and reliable, without any independent audits or peer reviews to back up these claims.

Ultrasurf VPN’s security technology seems to be a mixed bag, boasting industry-standard TLS encryption but leaving users in the dark regarding its proprietary encryption. Transparency is a virtue in the digital security sphere, and Ultrasurf VPN’s reluctance to reveal specifics about their encryption can give users pause.

Principles of Personal Data Protection and Jurisdiction

VPN services should not only encrypt data but also adhere to robust personal data protection principles. Let’s evaluate how Ultrasurf VPN fares in this regard.

Analysis of Personal Data Protection Principles

Ultrasurf VPN claims a “no-logs” policy, asserting that it does not store any personally identifiable information (PII). However, their privacy policy discloses that some user information, such as IP addresses and browsing history, may be temporarily stored for “troubleshooting purposes”. This appears to be a contradiction, as even temporarily stored data can potentially be exploited if the servers are compromised.

Furthermore, Ultrasurf VPN is not audited independently, leaving users to rely solely on the company’s claims of data protection. With competitors offering verified no-log policies, Ultrasurf VPN’s approach is less reassuring. The company would benefit from a comprehensive third-party audit to put these concerns to rest.

Company Jurisdiction

Ultrasurf VPN is based in the United States, which is a Five Eyes alliance member. This international agreement allows for the sharing of intelligence information between the USA, the UK, Canada, Australia, and New Zealand, which has significant implications for VPN users concerned about privacy.

The U.S. jurisdiction means that if pressured by law enforcement, Ultrasurf could potentially be required to disclose user information. The ambiguous logging policy, coupled with the jurisdiction risks, puts Ultrasurf VPN on shaky grounds when it comes to user privacy.

The early evaluation reveals some cracks in Ultrasurf VPN’s armor. While it offers basic encryption and data protection, a lack of transparency and potential privacy concerns may deter discerning users. As we delve further into the specifics of Ultrasurf VPN’s services in our upcoming sections, we aim to give you a comprehensive perspective, allowing you to make an informed decision. After all, your digital safety is paramount, and we are here to guide you in navigating the murky waters of online security.

Server Network

The effectiveness of a VPN service largely hinges on its server network. The geographical distribution, number, speed, and availability of servers can significantly impact a user’s experience. Let’s evaluate how Ultrasurf VPN measures up in this regard.

Overview of the Server Network

Ultrasurf VPN, originally designed to circumvent internet censorship in China, maintains a rather opaque approach to its server network. Unlike most VPN providers who disclose their server count and location, Ultrasurf VPN keeps this information under wraps.

The VPN’s website and application do not provide a list of server locations, which can be a major shortcoming for users needing to connect to specific regions for accessing geo-restricted content. While we understand that the VPN’s primary focus is on bypassing censorship, this level of secrecy can be a significant drawback for many users, particularly those who require a VPN for more than just anonymity.

Global Coverage and Availability

From user experiences and sporadic mentions in their FAQ section, we can glean that Ultrasurf VPN has servers in the United States. However, details about their global coverage and server availability remain elusive. The lack of transparency can be frustrating, especially for users who demand a VPN with comprehensive global coverage.

If you are an expatriate wanting to catch the latest shows on your home country’s streaming services or a globetrotter looking to secure your connection in different parts of the world, the scarcity of information from Ultrasurf VPN could be a potential dealbreaker.

Number of Servers

In line with the theme of opacity, the exact number of servers under Ultrasurf VPN’s umbrella remains a mystery. The website does not provide any information in this regard, which adds another layer of ambiguity to the service.

A vast server network is advantageous as it can handle more traffic, reduce server load, and improve connection speeds. Additionally, a larger number of servers provide users with more options to bypass geo-restrictions. Without information on their server count, it’s difficult to ascertain Ultrasurf VPN’s performance potential and capacity to handle heavy traffic.

Server Speed

Server speed is a crucial aspect of a VPN service. A swift server can make your online activities feel seamless, whereas a slow server can turn browsing into a tortuous task.

While Ultrasurf VPN claims to offer “fast and reliable” service, the absence of any data about server speed raises eyebrows. Given that most leading VPN services today provide detailed speed statistics to showcase their performance, Ultrasurf VPN’s silence on this front leaves a lot to be desired.

Server Speed Table in Different Countries

Due to the lack of transparency from Ultrasurf VPN about their server locations and speeds, it’s impossible to present a server speed table. The company’s reluctance to reveal this information might be tied to its origins as an anti-censorship tool, where secrecy can be beneficial. However, in the broader VPN market where transparency and performance are valued, this is a significant disadvantage for Ultrasurf VPN.

Streaming and Torrenting

One popular use of VPNs is bypassing geo-restrictions on streaming platforms and ensuring safe and anonymous torrenting. Let’s explore how Ultrasurf VPN fares in these areas.


Ultrasurf VPN promises to bypass internet censorship and allows users to access blocked websites. However, its effectiveness in unblocking popular streaming platforms like Netflix, Amazon Prime Video, BBC iPlayer, and Hulu is largely inconsistent according to user feedback.

While some users report successful unblocking, others complain of persistent issues. Additionally, the unknown server speed and locations could affect the streaming quality and experience. If accessing geo-restricted streaming content is your primary need, Ultrasurf VPN might not be your best bet.

Supported Services

With no explicit list of supported streaming services from Ultrasurf VPN, it’s challenging to ascertain its efficacy. User experiences vary greatly, indicating a lack of consistency in its performance.

Supported Services Table

Given the lack of clear information from Ultrasurf VPN, it’s not possible to provide a comprehensive table of supported services. What we know is based on mixed user experiences, which points to inconsistent effectiveness in unblocking streaming services.


As for torrenting, Ultrasurf VPN provides no explicit support or guidelines. Its opaque policy makes it unclear whether torrenting is safe or allowed. Therefore, if torrenting is a priority for you, Ultrasurf VPN might not be the most reliable option.

Supported Clients

Again, due to the lack of information from the company, it’s impossible to compile a list of supported clients for torrenting.

Supported Clients Table

As with streaming services, we cannot present a table of supported torrenting clients due to the absence of any official information or guidelines from Ultrasurf VPN regarding torrenting.

In conclusion, the lack of transparency from Ultrasurf VPN leaves users in the dark about many crucial aspects of its service. The undisclosed server network details and inconsistent performance with streaming and torrenting can be major deterrents for potential users. As we delve deeper into its compatibility, user-friendliness, pricing, and customer support in the following sections, we aim to provide you with a holistic view of Ultrasurf VPN’s offerings.

Compatibility and User-Friendliness

A superior VPN should be universally compatible with various platforms and user-friendly enough for even the most novice users to navigate with ease. Let’s see how Ultrasurf VPN stacks up in these areas.

Compatibility with Different Platforms

Ultrasurf VPN offers compatibility with a reasonably wide range of platforms. You can use it on Windows, Android, and iOS, thereby covering the major operating systems in use today. The software is easy to install and does not require any registration or login, offering a certain degree of anonymity right from the start.

However, the absence of support for MacOS and Linux is a glaring omission. Also, there’s no native support for routers, smart TVs, or other IoT devices. This lack of widespread compatibility might restrict its appeal among a broader audience. While Ultrasurf’s offering suffices for casual, individual users, the absence of compatibility with certain devices and platforms could be a deal-breaker for more tech-savvy users or those with multiple devices at home.

User-Friendliness Rating

The simplicity of Ultrasurf VPN is one of its strong points. Its minimalistic design makes it incredibly easy to use, even for beginners. There are no complex settings to navigate, no server lists to choose from, and no protocols to set up. The user interface is as simple as it gets – a connect/disconnect button and a few settings options.

However, this simplicity comes at a cost. Advanced users seeking customization options will find Ultrasurf VPN to be severely lacking. There’s no way to switch servers (since there are no server options available), and it lacks features like a kill switch or split tunneling, which have become standard in the VPN industry.

Overall, Ultrasurf VPN’s user-friendliness depends on your perspective. For novice users seeking a no-frills, easy-to-use VPN, Ultrasurf could be ideal. But for experienced users in need of advanced settings and customization options, the VPN’s service seems rather skeletal.

Pricing and Packages

Cost is a key factor in choosing a VPN. Most users are looking for a balance between affordability and features. Let’s delve into the pricing structure and package options offered by Ultrasurf VPN.

Overview of Prices and Packages

Ultrasurf VPN offers its service for free. Yes, you heard it right, no costs whatsoever. This could make it an attractive option for users on a tight budget or those who want to try a VPN without making a financial commitment.

However, as with most things in life, “free” comes with its own set of caveats. The absence of a clear revenue model raises questions about the VPN’s sustainability and ability to provide consistent and reliable service. After all, maintaining a robust server network and ensuring top-notch security are resource-intensive tasks.

Moreover, the saying “if you’re not paying for it, you’re the product” could hold some truth here. While Ultrasurf VPN maintains a no-log policy, the lack of a clear revenue model could lead one to question how the company makes its money. Transparency, once again, is a point of concern.

Download Ultrasurf

Given that Ultrasurf VPN’s service is entirely free, you can download it here.

Money-back Guarantee

Similarly, the notion of a money-back guarantee is irrelevant, given the lack of any payment structure.

It’s undeniable that a free VPN service like Ultrasurf could be a tempting proposition. However, the lack of transparency regarding their revenue model might raise red flags for users concerned about their data privacy and the sustainability of the service.

The simplicity and compatibility of Ultrasurf VPN also present a mixed bag. While the service might appeal to novice users who use supported platforms, the lack of advanced features and broader platform compatibility restrict its attractiveness for power users.

As we gear up to dive into the customer support offered by Ultrasurf VPN and compare it to its competitors, we aim to provide a comprehensive review that helps you make an informed decision. After all, in the world of VPNs, it’s crucial to find a service that strikes the right balance between usability, features, security, and price.

Customer Support

Effective customer support is a pivotal part of any reliable VPN service. Let’s delve into the kind of customer support Ultrasurf VPN offers to its users.

Table of Support Contact Options

Contact MethodAvailability
Live ChatNo
Phone SupportNo
Support TicketsNo
FAQ SectionYes

As you can see, Ultrasurf VPN’s customer support leaves a lot to be desired. They primarily offer support through their FAQ section and an email address. The FAQ section on their website provides answers to some common queries, but its comprehensiveness is debatable.

Lack of live chat and phone support could be a potential deal-breaker for users who might require immediate assistance. While you can reach out to their team via email, the response time is not guaranteed. This lack of instant customer support channels is a notable shortcoming and may make troubleshooting more challenging for users.

Pros and Cons

Every VPN service comes with its unique set of strengths and weaknesses. Below, we’ll take an analytical look at the pros and cons of Ultrasurf VPN.

Analysis of Advantages and Disadvantages

The biggest advantage of Ultrasurf VPN is undoubtedly its cost – or rather, the lack of it. The VPN service is entirely free, making it accessible to anyone. Additionally, its simplicity and ease of use could be attractive to beginner users who don’t want to navigate complex settings and configurations.

Furthermore, the VPN service does not require any registration, enhancing user anonymity. Its primary purpose – to bypass internet censorship – seems to be fulfilled reasonably well, according to various user reviews.

On the downside, the lack of transparency is a major concern with Ultrasurf VPN. The undisclosed server network details, unspecified revenue model, and non-existent customer service can make potential users wary.

Moreover, the absence of advanced features like a kill switch, split tunneling, or customizable settings, and lack of support for platforms like MacOS, Linux, and routers can limit its utility for advanced users or those with specific requirements.

As we move onto comparing Ultrasurf VPN with its competitors, we’ll provide a better context of how it stacks up against other leading players in the market, helping you make an informed decision.


Now, let’s see how Ultrasurf VPN measures up against some of the leading VPNs in the market. For this comparison, we’ll consider NordVPN, Surfshark VPN, PureVPN, and ExpressVPN.

Ultrasurf VPN vs NordVPN

NordVPN is one of the top-rated VPNs on the market, known for its advanced features and robust security protocols. While Ultrasurf VPN’s zero-cost offering may seem attractive, it’s a stark contrast to NordVPN’s extensive features, which include advanced security options, a kill switch, and a choice of over 5000 servers in 59 countries.

Moreover, NordVPN offers 24/7 customer support, including live chat, a comprehensive FAQ section, and email support. This stands in sharp contrast to Ultrasurf’s minimalistic email support and FAQ section. NordVPN also provides a clear no-logs policy and is based in Panama, a country with strong privacy laws.

While NordVPN does come with a price tag, it offers a 30-day money-back guarantee, allowing you to test the service risk-free.

Ultrasurf VPN vs Surfshark VPN

Surfshark VPN is another strong contender in the VPN market, boasting over 3200 servers in 65 countries. Like NordVPN, Surfshark VPN offers a plethora of features, including MultiHop (connecting via multiple countries at once), CleanWeb (blocking ads, trackers, and malware), and a kill switch.

In terms of customer support, Surfshark VPN outshines Ultrasurf VPN, providing 24/7 live chat, email support, and a comprehensive FAQ section. Furthermore, Surfshark VPN operates under a strict no-logs policy and is based in the British Virgin Islands, a jurisdiction with strong privacy laws.

While Surfshark VPN is a paid service, it offers a 30-day money-back guarantee and allows unlimited simultaneous connections, making it a cost-effective choice for families or multiple device owners.

Ultrasurf VPN vs PureVPN

PureVPN stands out in the VPN industry with its whopping 6500+ servers in over 140 countries. Unlike Ultrasurf VPN, PureVPN offers apps for all major platforms, including smart TVs and routers. It also provides advanced features such as split tunneling, a kill switch, and secure Wi-Fi.

Customer support is a strong point for PureVPN, with 24/7 live chat, email support, and an extensive FAQ section. The service operates under a no-log policy and is based in Hong Kong, which does not require data retention.

While PureVPN is a paid service, it offers a 31-day money-back guarantee, allowing users to try the service without any risks.

Ultrasurf VPN vs ExpressVPN

ExpressVPN is another industry giant, known for its robust security, fast speeds, and extensive global coverage with 3000+ servers in 94 countries. It offers a suite of advanced features, including split tunneling, Network Lock (kill switch), and its proprietary Lightway protocol for faster connections.

In contrast to Ultrasurf’s scant customer support, ExpressVPN offers 24/7 live chat support, email support, and a vast library of tutorials and guides. ExpressVPN follows a strict no-logs policy and is headquartered in the British Virgin Islands, away from 14 Eyes surveillance.

Although ExpressVPN comes at a premium price, it offers a 30-day money-back guarantee, allowing you to test out its comprehensive features risk-free.


Ultrasurf VPN offers a simple, free service, primarily aimed at users looking to bypass internet censorship. Its no-frills approach and lack of registration requirements might appeal to casual users who need a basic VPN service.

However, the lack of transparency in Ultrasurf VPN’s operations, coupled with its minimal customer support and missing advanced features, can deter more demanding users. Furthermore, the limited platform compatibility restricts its utility for users with macOS, Linux, or other unsupported devices.

In contrast, the four alternatives—NordVPN, Surfshark VPN, PureVPN, and ExpressVPN—all offer a comprehensive suite of features, extensive platform compatibility, robust customer support, and clear policies around data logging and privacy. Although these services come at a cost, they offer a more reliable, feature-rich, and secure VPN service.

In conclusion, Ultrasurf VPN may suffice if you’re looking for a free, simple service to overcome internet censorship. However, if you require a full-fledged VPN with a wide range of features, extensive server network, superior customer support, and transparent operating practices, it would be worth considering the alternatives.

As with any digital service, it’s crucial to weigh the pros and cons based on your specific needs before deciding on the VPN service that’s right for you.


Can Ultrasurf be blocked?

Yes, Ultrasurf can be blocked. While Ultrasurf is designed to bypass internet censorship, some networks or countries with stringent internet restrictions might still manage to block it. This is achieved by identifying and blocking the IP addresses of Ultrasurf’s servers or by using deep packet inspection (DPI) to detect VPN traffic.

Who owns Ultrasurf?

Ultrasurf is a product of UltraReach Internet Corporation. UltraReach is a company dedicated to providing internet freedom and privacy for users around the world. It was originally created to help internet users in China bypass heavy internet censorship.

Is Ultrasurf Chrome extension safe?

As of my knowledge cutoff in September 2021, Ultrasurf’s Chrome extension was considered reasonably safe, but like any browser extension, it comes with some caveats. While it does encrypt your browsing data, it’s not a full-fledged VPN and only secures data transmitted within the Chrome browser. Also, the extension doesn’t have the advanced features that you’d find in more robust VPN services. It’s also worth noting that browser extensions can be more susceptible to leaks and attacks than standalone VPN apps.

Does Ultrasurf still work?

Yes, Ultrasurf is still operational and continues to provide its VPN service. However, the quality, speed, and effectiveness of the service can vary greatly, especially since it’s a free service with limitations. It’s important to keep in mind that Ultrasurf primarily aims to circumvent internet censorship, and as such, may not offer the advanced features, speeds, or security protocols that paid VPN services provide.

Is Ultrasurf a free VPN?

Yes, Ultrasurf is a free VPN. One of the main selling points of Ultrasurf is that it’s entirely free to use. There are no subscription fees or trials; you can download and use Ultrasurf without paying a dime.

Is Ultrasurf unlimited?

Ultrasurf doesn’t explicitly state any limitations on data or bandwidth on its website, making it an ‘unlimited’ service in that sense. However, due to its nature as a free service, users might experience slower speeds during peak times or if the servers are congested. Also, the absence of detailed information about their server network raises questions about the overall capacity and performance of the service.
