What are the Disadvantages of Public Proxies?
Just googling “free proxy servers” will find you thousands of proxy servers.
More often than not, these services are too slow and unreliable to use. Since they are open to anyone, public proxies typically have very limited speeds and bandwidth.
Also, keep in mind that when you connect to a public proxy server, you are potentially opening up a ‘direct line’ into your company’s network.
If you don’t know who owns or manages those public proxy servers and network connections, you risk monitoring of your communications. This can lead to theft of sensitive data and can also expose your company to malware.
“There’s no such thing as a free lunch” is just as applicable in the proxy server industry. If you’re using proxy or IP rotation services, or free P2P networks that seem too good to be true, it’s likely that you’re connecting to a botnet and using other’s compromised devices without their knowledge. That opens up huge security and legal risks for your company.
Even if you’re told all the users in the network have consented, hackers may be using these networks. They may conduct sophisticated ‘man in the middle’ attacks to try and trick their way into other networks.
