UltraSurf is a free program, designed to help users in heavily-censored countries to surf the internet freely. Unfortunately, as of the time of this writing, the security of this program has been compromised, and there have been reports of this program using personal computers to attack government and financial websites. Thankfully, there are a number of secure programs that provide the same services.
1)Tor
Tor is a free, open-sourced program that allows users to surf the internet anonymously.
Advantages:This program is one of the most well known internet anonymizers available. It allows users to surf the web via the use of proxy servers based in other countries. Because of the basic nature of a proxy server, it allows users to surf the net freely by effectively bypassing their country’s firewalls.
Disadvantages: The only real downside of Tor is speed. Because the program is free and does not set a limit on how much bandwidth a user can utilize, it is much slower than some of the other commercial options.

2)Hotspot Shield
Hotspot Shield is a program that, while originally designed to protect users while using public internet connections, also works very well for bypassing censorship.
Advantages: The basic program itself is free. It provides access to a VPN server for anonymous browsing, which by default also allows the user to bypass country-based firewalls and censorship. It also provides a secondary layer of protection for online transactions.
Disadvantages: The free program can only be used on one device. The elite version, for a yearly subscription fee of $29.95, offers support for up to 5 devices, as well as bonuses like cloud-based malware protection and dedicated customer support.

Advantages: The basic program is free. It allows for complete privacy while surfing or shopping online. Since it utilizes VPN servers, it is also a useful tool for bypassing country-based website censorship. A free user can use up to 1GB of data traffic per month.
Disadvantages: Premium accounts, which allow the use of 40GB of data traffic per month, run $6.99 monthly or $69.99 for a 24-month subscription. For users who need this program on more than one device, the price goes up to $10.99 monthly or $109.99 for 24 months.
