Paid and free proxy: comparison, advantages and disadvantages

Proxy server is a computer, one that mediates between a user’s computer and other servers on the Internet. All user requests and results from the network go through the proxy server. When a subscriber accesses the network from his PC, his IP address is transmitted to the servers to which he makes requests. This address can be used to identify the subscriber’s location, the number of his computer, the number of the provider. The intermediary server performs a lot of different functions, but its main mission is to protect this address from other servers. In general, main functions of proxy server are as follows:

• the server connects the user’s computer to the local network;
• it saves (caches) customer’s data in case of frequent requests to the same source. Thus, speed of occurrence of all necessary data increases without any additional load on network channels;
• The proxy saves Internet traffic by composing the data taken from the Internet. The user receives them tightly packed, thereby not wasting extra gigabytes of traffic;
• It protects the internal network from any external influences or interference. This is done by setting up, which will address the local PCs only through the server-intermediary. External PCs will not be able to access them in any way;
• It restricts access to the World Wide Web from the internal network. With a mediation server there is a chance to limit the use of the network to some of its users, as well as not allow them to access some sources. It is often practiced by employers to prevent employees from spending their working hours in public networks;
• A proxy ensures the anonymity of the user on the Internet. All your own data will not reach the target source. Say, when sending a request the target source will get the IP of the proxy, not the customer.

Paid and free proxy: main advantages and disadvantages

An undoubted advantage is the simultaneous use of several proxy. As a rule, they react rather quickly and are a good competitor to their paid counterparts. But it should be understood that this free method has a downside. In the case where a customer creates a whole chain of multiple proxy-servers, greatly increases the level of anonymity on the Internet, but at the same time tremendously reduced speed. It is the quality of communication that is the bane of free proxy servers. In a saturated job, they are able to fail the customer at any time. When using a free proxy server, you should keep in mind that there are two main scenarios. In the first case, we are talking about a new server that needs promotion and therefore it is free. Krupnaya probability that later it will become a paid. The second option is much sadder – the server is completely closed due to the fact that it is outdated. In general, similar servers are very limited in terms of functionality, they do not own anonymity, and, as a rule, similar in nature between themselves. But, there is also the most negative and the most basic variant of becoming – virus and spyware, criminals who gain access to your PC and pursuing the following criminal purposes:

• collecting data about computers (what programs are used, where the computer is located, etc.);
• transmitting additional information through package spoofing;
• Conducting activity on the Internet on behalf of the server customer. As a rule, this activity is criminal or immoral and can compromise the user;
• theft of confidential information about the customer (passwords, banking data, electronic wallets, accounts in social networks and other personal information);
• launching scripts from a subscriber’s computer;
• PC infection with viruses;
• DDoS attacks using a user’s computer.
