What it does: 

Allows users to access blocked sites in countries where the internet is censored, without installing additional software. Psiphon turns a regular home computer into a personal, encrypted server capable of retrieving and displaying web pages anywhere. You can then give out access to friends and contacts who live in a censored internet environment.

When to use it: 

If you live in a country that blocks access to certain websites.


It will not allow you to access secure or encrypted web pages (HTTPS) and it will not protect you from malicious websites.

Suggested use: 

Give key people and stakeholders uncensored access if they are inside countries that are censoring the internet.

Security concerns: 

You need to trust your psiphon provider and know they are not misusing the service.
