High Anonymity Web Proxy Service
Many important use cases are best supported by high levels of proxy anonymity. This article describes three generally accepted categories of proxy anonymity. The main criterion is the degree of exclusion of certain header information from requests over the Internet to a web-server.
High Anonymity Web Proxy Service
As detailed below, the ProxyMesh rotating proxies and our static-IP World Proxy provide the highest type of anonymity, called Level 1 Elite, while our open proxy is in the Level 2 Anonymous category.
Elite Level 1 Proxies, also called High Anonymity Proxies, provide the very highest level of anonymity. With this type of proxy, the server you connect to receives no information about your actual IP address. In fact, it cannot even detect that the connection was made through a proxy.
ProxyMesh's Elite Level 1 proxies enable this degree of anonymity in part by stripping out all identifying headers so that they're not passed along in requests. The following headers are removed to prevent proxy identification by the remote site:
Level 3 Transparent proxies do not hide your IP address from a server you are connecting to, so it does not provide anonymity. Although your address may not be immediately obvious, it's easy to find it out. Requests from transparent proxies pass in the proxy's IP address in the Via header and your IP address in the X-Forwarded-For header.
Modern proxy servers do much more than forwarding web requests, all in the name of data security and network performance. Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet. Lastly, proxy servers can provide a high level of privacy.
A proxy server is used for a variety of purposes, including functionality, security, and privacy. With a proxy, you can control the internet usage of employees, save on bandwidth for faster connectivity, load balance between services, and access blocked resources.
Transparent proxies are well-suited for companies that want to make use of a proxy without making employees aware they are using one. It carries the advantage of providing a seamless user experience. On the other hand, transparent proxies are more susceptible to certain security threats, such as SYN-flood denial-of-service attacks.
A anonymous proxy is best suited for users who want to have full anonymity while accessing the internet. While anonymous proxies provide some of the best identity protection possible, they are not without drawbacks. Many view the use of anonymous proxies as underhanded, and users sometimes face pushback or discrimination as a result.
Rotating proxies are ideal for users who need to do a lot of high-volume, continuous web scraping. They allow you to return to the same website again and again anonymously. However, you have to be careful when choosing rotating proxy services. Some of them contain public or shared proxies that could expose your data.
FortiGate has the capability of both proxies and VPNs. It shields users from data breaches that often happen with high-speed traffic and uses IPsec and SSL to enhance security. FortiGate also harnesses the power of the FortiASIC hardware accelerator to enhance performance without compromising privacy. Secure your network with FortiGate VPN and proxy capabilities.

High anonymity proxies offer the most security to a user. They conceal the user's IP address and do not identify themselves as proxies to web servers (unlike anonymous proxies). These proxies routinely change IP addresses when making requests to web servers, allowing a high level of privacy.
A CGI (Common Gateway Interface) proxy is a type of web proxy server that allows users to access websites anonymously via a web form. As CGI proxies are web-based, they allow users to access the proxy's services on devices or networks that do not allow proxy configurations.
Public proxies are ideal for cost-sensitive users but not for those with data security and speed concerns. As many users are drawn in by the free service of public proxies, they are prone to lagging. The open nature also puts users at higher risk of compromising sensitive data if they share personal information through the proxy, much like public wi-fi networks.
Like any third-party service operating over the Internet, proxy servers are not without their cyber risks. Users should understand the common risks associated with proxies to decide if they are fit-for-purpose.
While proxy services offer some privacy to the user by concealing their IP address, the proxy itself logs this information, along with browsing history. Depending on the type of proxy, this data could be forwarded to external parties, causing a data breach.
Instead of connecting directly to a server that can fulfill a request for a resource, such as a file or web page, the client directs the request to the proxy server, which evaluates the request and performs the required network transactions. This serves as a method to simplify or control the complexity of the request, or provide additional benefits such as load balancing, privacy, or security. Proxies were devised to add structure and encapsulation to distributed systems. A proxy server thus functions on behalf of the client when requesting service, potentially masking the true origin of the request to the resource server.
Many workplaces, schools, and colleges restrict web sites and online services that are accessible and available in their buildings. Governments also censor undesirable content. This is done either with a specialized proxy, called a content filter (both commercial and free products are available), or by using a cache-extension protocol such as ICAP, that allows plug-in extensions to an open caching architecture.
A caching proxy server accelerates service requests by retrieving the content saved from a previous request made by the same client or even other clients. Caching proxies keep local copies of frequently requested resources, allowing large organizations to significantly reduce their upstream bandwidth usage and costs, while significantly increasing performance. Most ISPs and large businesses have a caching proxy. Caching proxies were the first kind of proxy server. Web proxies are commonly used to cache web pages from a web server. Poorly implemented caching proxies can cause problems, such as an inability to use user authentication.
A proxy that is designed to mitigate specific link related issues or degradation is a Performance Enhancing Proxy (PEPs). These are typically used to improve TCP performance in the presence of high round-trip times or high packet loss (such as wireless or mobile phone networks); or highly asymmetric links featuring very different upload and download rates. PEPs can make more efficient use of the network, for example, by merging TCP ACKs (acknowledgements) or compressing data sent at the application layer.
Access control: Some proxy servers implement a logon requirement. In large organizations, authorized users must log on to gain access to the web. The organization can thereby track usage to individuals. Some anonymizing proxy servers may forward data packets with header lines such as HTTP_VIA, HTTP_X_FORWARDED_FOR, or HTTP_FORWARDED, which may reveal the IP address of the client. Other anonymizing proxy servers, known as elite or high-anonymity proxies, make it appear that the proxy server is the client. A website could still suspect a proxy is being used if the client sends packets that include a cookie from a previous visit that did not use the high-anonymity proxy server. Clearing cookies, and possibly the cache, would solve this problem.
"A 'transparent proxy' is a proxy that does not modify the request or response beyond what is required for proxy authentication and identification". "A 'non-transparent proxy' is a proxy that modifies the request or response in order to provide some added service to the user agent, such as group annotation services, media type transformation, protocol reduction, or anonymity filtering".
A suffix proxy allows a user to access web content by appending the name of the proxy server to the URL of the requested content (e.g. "en.wikipedia.org.SuffixProxy.com"). Suffix proxy servers are easier to use than regular proxy servers but they do not offer high levels of anonymity and their primary use is for bypassing web filters. However, this is rarely used due to more advanced web filters.
The I2P anonymous network ('I2P') is a proxy network aiming at online anonymity. It implements garlic routing, which is an enhancement of Tor's onion routing. I2P is fully distributed and works by encrypting all communications in various layers and relaying them through a network of routers run by volunteers in various locations. By keeping the source of the information hidden, I2P offers censorship resistance. The goals of I2P are to protect users' personal freedom, privacy, and ability to conduct confidential business.
High anonymity proxies are also known as elite proxies. A high anonymity proxy or elite proxy has a number of additional unique features, apart from the basic functions that any other HTTP proxy can do. High anonymity proxies have all the advantages of anonymous proxies in terms of privacy, but can also conceal the fact that a user is using a proxy server.

A high anonymity proxy works in the same was a regular HTTP proxy: an HTTP client (e.g., a web browser) sends web requests to an elite proxy which in turn forwards it to the actual web server. The web server sees the proxy server simply as another connection and answers it as usual. The proxy server then delivers the HTTP response to the client. 041b061a72
