Proxy Servers and Their Types: How to Choose the Best One for Data Protection

Proxy servers are a crucial component for ensuring anonymity and security online. They function as intermediaries between the user and the target website, masking the user's real IP address and filtering traffic, helping to protect data from interception.

1. User Makes a Request – For example, visiting a website or trying to download a file by sending a request to the internet.
2. Request is Sent to the Proxy Server – Instead of directly reaching the target server, the user sends the request to a proxy server, which acts as an intermediary and hides the real IP address.
3. The Proxy Server Checks and Filters the Request – The proxy can perform multiple functions:
   • Blocking malicious websites and unwanted content.
   • Inspecting traffic for security threats.
   • Modifying requests, such as bypassing restrictions or changing regions.
4. The Target Server Processes the Request and Sends Back Data – The request reaches the intended resource, which processes it and returns the requested data.
5. The Proxy Server Delivers Data to the User – The proxy server receives the response from the target server and forwards it to the user while keeping the real IP address hidden.

The main advantage of using proxy servers is anonymity. A proxy hides the user's real IP address, making it difficult to track their online activities. It is important to note that hiding an IP address helps prevent:

• Surveillance of user activities.
• Collection of personal data for targeted advertising.
• Risks associated with direct access to user data.

Proxy servers also serve as traffic filters. This helps to:

• Block malicious websites, protecting users from phishing, viruses, and other threats.
• Encrypt traffic. Some proxies support encryption, which is crucial for data protection, especially in open and unsecured networks such as public Wi-Fi.
• Detect threats. Proxies can analyze traffic for potential threats and block potentially dangerous data packets.

Proxy servers come in different types, each with its own specific features suited for certain tasks. Let’s take a closer look at the main types of proxy servers.

An HTTP proxy is the most common and basic type of proxy used for browsing web pages via the HTTP protocol.

Features:

• Ease of use. HTTP proxies are suitable for simple internet surfing. They are ideal for working with non-secure web pages and allow users to hide their real IP addresses, increasing anonymity.
• No encryption. One of the downsides is the lack of data encryption, making this type of proxy vulnerable to data interception, especially in unsecured public Wi-Fi networks. Therefore, HTTP proxies do not provide adequate protection for transmitting confidential data.
