In terms of origin, there are two types of proxies, data centre and residential:
A data center proxy is a private proxy that is not affiliated with an ISP because it comes from a secondary corporation and provides a private IP authentication, high-level anonymity and rapid data request response times. Usually, data center proxies are used for infrastructure, such as servers and web hosting.
A residential proxy is an intermediary using an IP address attached to a physical location provided by an Internet Service Provider (ISP) to a homeowner. It is a genuine IP address that can be used to imitate organic users are proxies used for? As mentioned before, individuals and businesses widely use proxies. Let’s explore the reasons behind it.
Personal use A proxy used for a personal case will be attached to a particular location. This can enable certain access to geo-blocked content. For example, consumers can browse and purchase flights from locations that offer the most advantageous prices.
Secondly, proxies can optimize user’s web activity and improve security levels by encrypting requests.
Business use In most cases, businesses use proxies to gain advantage over competitors by gathering insightful information. The proxy gives them the ability to extract and process large amounts of publicly available data on competitor prices, products, services, reviews or even market trends that can accelerate businesses in their decision-making process regarding adapting marketing, sales and pricing strategies.
Such information would be impossible to extract without proxies in place due to recurring blocks. When data gathering is in progress, a large number of requests are made to a web server.
The difficulty arises when these requests come from the same IP address because websites identify this activity as suspicious and block the IP address for security reasons. Proxies prevent this as IP addresses can be constantly changed if rotating proxies or a proxy rotator is used. This way data gathering can continue to take place anonymously and efficiently.
In addition to data gathering, many businesses use proxies for email security as there are huge amounts of emails that contain malware attachments, ransomware or suspicious URLs. Proxies help to scan each inbound email and filter out malicious content.
Another common use case is brand protection, as proxies are employed to scan the web searching for stolen content or counterfeit is the difference between paid proxies and free proxies? With a free proxy you can access almost every proxy benefit, which is great until something goes wrong. Utilizing such services means that no one is responsible for technical faults, which happen to be a common occurrence in this case.
It is not easy to find a free, long-life proxy as they quickly become outdated and the providers usually turn into paid ones or disappear over time. Furthermore, using free proxies can pose a serious threat because you never know if your data is secure and you may run the risk of falling victim identity theft.
Paid proxies are responsible for their services, with contracts and agreements in place to protect the user. For businesses, there is no other option but to pay for a dedicated proxy service and avoid any potential security issues. If you choose a reliable proxy provider, you should not need to worry about servers crashing or disappearing for no reason as many will offer dedicated account support.
A reliable proxy provider will also have ethically sourced proxies. Deciding what proxy provider to choose is not an easy task as there are many criteria to consider, but we have singled out a few key points:
Reliability: 24/7 customer support and account managers, service trials and a money-back guarantee are must-haves for a reliable proxy provider. Pay attention to client reviews as well
IP pool size and location: IP pool size and location variety are critical for those who will be scraping large amounts of data from various countries
Success rates and speed: a reliable proxy network success rate should be at least 90%, with the best providers guaranteeing 95% or higher
Integration and support: proxy providers must ensure their documentation is clear and understandable, including integration tutorials and clear instructions
The future of proxiesBusinesses mostly use proxies for large-scale data gathering and extraction, but this is not an easy process. It consists of many complex tasks, especially when anti-data gathering measures are becoming more sophisticated and making it harder to collect publicly available information without being blocked. To address this, Artificial Intelligence (AI) and Machine Learning (ML) innovations are gradually being applied. Ultimately, proxies are extremely valuable solutions for both individuals and businesses that need to make accurate data-driven decisions. For individuals, proxies can help to access geo-blocked content, improve security levels, and optimise a web activity. For businesses, not only will they provide an extra layer of security, but they are quickly becoming an indispensable tool to gather publicly available information.

Proxy (statistics) – Wikipedia
In statistics, a proxy or proxy variable is a variable that is not in itself directly relevant, but that serves in place of an unobservable or immeasurable variable.  In order for a variable to be a good proxy, it must have a close correlation, not necessarily linear, with the variable of interest. This correlation might be either positive or negative.
Proxy variable must relate to unobserved variable, must correlate with disturbance, and must not correlate with regressors once disturbance is controlled for.
Examples In social sciences, proxy measurements are often required to stand in for variables that cannot be directly measured. This process of standing in is also known as operationalization. Per-capita GDP is often used as a proxy for measures of standard of living or quality of life. Montgomery et al. examine several proxies used, and point out limitations with each, stating “In poor countries, no single empirical measure can be expected to display all of the facets of the concept of income. Our judgment is that consumption per adult is the best measure among those collected in cross-sectional surveys. “ Likewise, country of origin or birthplace might be used as a proxy for race, or vice versa.
Frost lists several examples of proxy variables: Widths of tree rings: proxy for historical environmental conditions; Per-capita GDP: proxy for quality of life; Body Mass Index (BMI): proxy for true body fat percentage; years of education and/or GPA: proxy for
cognitive ability; satellite images of ocean surface color: proxy for depth that light penetrates into the ocean over large areas; changes in height over a fixed time: proxy for
hormone levels in blood.
