An organization can find many uses for a proxy server. The needs of a small family business will differ vastly from those of a multinational banking corporation. But they both have a need for quality proxy servers. Transparent proxies can provide an important service. This article describes how they work and why they might be the right choice for you.
How do they work?
Level 3 Transparent proxies, also known as caching proxies, gateway proxies, or filtering proxies, are helpful in improving network speed. They are used by large organizations such as hotels, airports, and ISPs, allowing them to proxy requests without having to configure individual computers that use the proxies. They are also used by cloud-based systems that route data packets through multiple proxies but always show the primary IP address.
The proxies work by intercepting and redirecting data without modifying the information that passes through them. They do not offer anonymity, since they do not hide your IP address from the connecting server. This presents the potential risk of hackers knowing your IP address and collecting data from your computer.
From large companies to academic institutions, transparent proxies are used by many organizations to improve productivity by monitoring employee activity and limiting what users can access on their network.
For enterprises like ISPs, these proxies can be useful in caching data and speeding access to frequently used websites. For example, when someone accesses a website and wants to stream a video, the ISP can cache the video on its own servers so that the next time someone wants to watch that same video, they will be redirected to the cached version – a shorter and faster trip than if they’d gone to the original location.
Particularly useful for companies such as hotels or restaurants offering public wi-fi, transparent proxies verify the authenticity of users before giving them internet access. Users are directed to a login page to submit certain access information. This is designed to ensure that users agree to the site’s terms and conditions as a condition of network access.
The bottom line
Give careful consideration to whether transparent proxies can be a useful tool for the needs of your company. Since they do not offer anonymity, the potential risk from hackers knowing your IP address may be high. At times when it’s especially important to prevent that, it’s best to avoid free proxies and sign up with a good paid proxy service that can provide the security and service you need.
