Major problem of public proxies is their accessibility. They break down way too fast and have some problems related to information security. Regular use of ZennoProxyChecker guarantees reliable protection and privacy of your data when using filtered proxies.
Connection issues, web connection speed drops are most commonly noticed by users that use free proxies. This leads to slowdown of your software or even to its hang-ups.
Despite these proxies offer high degree of privacy and good uptime, this gives no guarantees that they can remain up and running forever. Besides, if ZennoProxyChecker shows low anonymity level for your proxies, this is just a good reason to seek for another proxy from your proxy provider.
If you operate with valuable data like logins, passwords, phone numbers or payment details, we recommend choosing elite proxies only. ZennoProxyChecker offers a dedicated filter specifically for this purpose.
