A study of 443 free proxies conducted by security researcher Christian Haschek showed that most proxies on the web are not secure.
To do this study, Christian used several methods to verify the security and proper functioning of proxies.
To check the security of a proxy server, the researcher used his Proxy Checker script.
Proxy Checker is a script that allows you to check the following points:
- If the proxy is online
- Whether the use of secure HTTPS connections are allowed
- Whether your IP address will be anonymous
- If the proxy modifies the html of the visited sites
You can also use this script to check the security of proxy servers that you plan to use.
For that, it is enough toaccess the proxy checker site, enter the proxy address with the port used then click on Analyze.
