1. Free proxies bring great security risks. In fact, free proxies currently offer little protection against a variety of external threats, including malware attacks, traffic blocking, and data theft.
2. Free proxies are almost always poorly encrypted or not encrypted at all. The last thing you want to do is send unencrypted data to an unauthorized third party. Imagine sending your complete credit card data in plain text to people you don't know. That would be a stupid thing to do, right? If you plan to use a proxy service, you must be 100% sure that all of your valuable data is completely secure.
3. Poor maintenance and lack of customer support. If the service crashes or your device is infected with malware, no one is responsible but you. Free proxies are very unreliable because so many people are seduced by the idea of not paying a dollar for service.
4. Free proxy lists are often filled with blocked or ineffective agents. The important thing to remember here is that when you use a public proxy list, you are sharing IP addresses with other users who are less concerned with IP prohibitions. In short, don't get too excited when you find a list of free agents with thousands of ips. You may only be able to use 1% of this list.
5. Free proxies are slow. Most importantly, they are not always completely free. Of course, they're advertised as free, but once you sign up, you may find that there are a lot of hidden costs that prevent you from doing what you need to do.
If you need multiple different proxy IP, we recommend using RoxLabs proxy, including global Residential proxies, with complimentary 500MB experience package for a limited time.
