Publisher's Description of Ultrasurf
|
" World's most popular pro-privacy, anti-censorship software to bypass firewalls and protect their identity online. "
- From Ultrareach Internet Corporation
Ultrareach Internet Corp., was founded by a small group of Silicon Valley engineers dedicated to the promotion of the free exchange of information. Ultrasurf, one of the world's most popular pro-privacy, anti-censorship software enables internet users to protect their security and anonymity online while bypassing censorship and firewalls, and is completely free to users.
The tool was originally designed for internet users in Mainland China, where the internet is heavily censored and internet users' activities monitored. With the advent of Ultrasurf and other circumvention tools, these internet users are provided a lifeline to access and share information freely. After nearly a decade of development, our technology has proven extremely resilient and adaptable in the face of increasingly advanced censorship techniques and aggressive blocking attempts.
Ultrasurf also helps internet users in non-censoring countries to bypass firewalls, encrypt their communications, and protect their IP address; it is recommended in particular for use at wireless hotspots and public WiFi networks.

Features:
* Transparent to the user: Users who wish to view or adjust their connection settings can do so easily using the Ultrasurf interface

* Easy to use: Ultrasurf can be easily downloaded, and launches by double-clicking. No additional adjustments are necessary
* Fast: Ultrasurf has tested as the fastest among ten popular censorship and anonymizing devices, and as we continue to upgrade our server capacity, it becomes even faster and more reliable
* Unblockable: Client uses wide array of discovery mechanisms to find an available proxy server and, when necessary, to switch/hop to avoid tracking/blocking
* Lightweight: Ultrasurf is a small file of less than 1.3M in size, making it easy to download and share
* Portable: No installation necessary: can be run, e.g. in a cybercafe, off of removable media such as a USB thumbdrive or the SD card used in cameras
* Invisible: Leaves no traces on the user's computer, and its traffic is indistinguishable from normal access to HTTPS sites
* Anonymous: No registration is requires, and no personally identifying information collected
* Tamperproof: Using privately-signed SSL certificates which don't depend on external, potentially compromised CAs (thus preempting MITM attacks), Ultrasurf proactively detects attempts by censors to reverse-engineer, sabotage, or otherwise interfere in the secure operation of the tool
How does it work?
When a user launches Ultrasurf, the tool automatically discovers the best available proxy servers from our central server pool and connects the user to it via an encrypted tunnel. In this process, the user's IP address is masked, and all their activities and communications are securely encrypted. This allows users to circumvent surveillance, bypass firewalls, and overcome blocking and censorship.
