Proxy server Simple English Wikipedia, the free encyclopedia

The forward proxy then receives the replies to those requests and passes them back to the proxy user. Forward proxies can be configured to evaluate, or screen, internet traffic and handle the requests based on specified criteria. An IP address functions like a home address for your computer or device. Just as mail is delivered to the physical address of your home, your internet requests are returned to your unique IP address, ensuring that data gets transmitted to the right location. Acting as intermediaries, proxies help protect your privacy and strengthen the security of your local network. A proxy server relays traffic between your device and the web, ensuring that your browser is never in direct contact with the sites you visit.

The proxy masquerades itself in such a way that the client and server believe that they are talking to each other even though there is a proxy in between. A proxy server can be placed anywhere in the connection between the client and the server, which could include software on the client computer itself or on any computer between. A client that connects to the proxy server will ask for some service, such as a file, connection, web page, or other resource, that is available on a different server. The proxy server then goes to the other server and asks for what the client wants for them. An HTTP proxy enables businesses and users to hide their real IP addresses, ensuring privacy and preventing anyone from snooping on their activity. HTTP does not have inherent security measures, so from 2010 onwards, websites have used HTTP Secure (HTTPS).

Why have I been blocked?

It can be beneficial to hide your IP address because a hacker, troll, stalker, or any other type of bad actor can use it to learn more about you, like your general geographical location. Cybercriminals can also use your IP address to target you with scams that may sound convincing because they involve information about your location. Similarly, law enforcement officials or state actors may also use an IP address to track something through an ISP (Internet Service Provider). With this plethora of cyberattacks, it only makes sense to invest in security and privacy. And not just data assets, but physical assets too when you consider the possible costs of replacing an organization’s hardware when a virus renders it unusable. In this article, we dig a little deeper to uncover why you need to know what a web proxy can do for your network.

Say you bought a pair of shoes from a store and then resold them at your yard sale. The buyer only knows where they got the shoes (from your sale), so they are like the website, which knows only the location of the proxy (your yard sale). The buyer doesn’t communicate directly with the store, and neither do you communicate directly with the destination website when you’re on a web proxy. The proxy concept refers to a layer 7 application in the OSI reference model. Network address translation (NAT) is similar to a proxy but operates in layer 3.


FortiProxy delivers broad protection and visibility to every network segment, device, and appliance, whether deployed virtually, in the cloud, or on-premises. FortiProxy also provides unparalleled SSL decryption capabilities with on-board hardware acceleration. Plus, it integrates with key Security Fabric components, such as FortiSandbox, for AI-powered zero-day file malware analysis, and FortiAnalyzer for centralized log analysis. They give you access to an IP address that may be shared by other people, and then you can surf the internet while appearing to browse from a location of your choice. They won’t see the sites you access through the web proxy, but the fact that you’re connected to the proxy site is still visible.

It offers network security for users and enables simple administrative control. A forward proxy, however, might make it more difficult for an organization to meet each end-user’s specific needs. More than that, proxy servers also compress traffic and remove ads from websites, thereby making the internet faster than usual. Enterprise companies might have confidential proprietary information, their employees’ private data, as well as their customers’ personal information sitting on their local network.

Are proxies the same as VPNs?

The user gets an anonymized IP address but at the cost of their data being logged on the web proxy server. A corporate web proxy server has few disadvantages, but public services open for anyone to use have risks. These risks are eliminated if organizations use network controls to force users to only use the approved proxy server. Network administrators can lock web browser configurations using domain controls such as Active Directory. They are sometimes called “transparent” proxy servers, because the user does not know a proxy server is between the client and remote server. An anonymizing proxy server removes identifying information from the clients’ requests, for the purpose of anonymity.

This can be a problem when a business needs to access a geo-restricted website, but when a company uses a proxy server, the IP is masked and employees can access the content they need. Proxy servers in many forms enhance security but like many things in computing may be vulnerable themselves. Reverse proxies may be used to prevent access to immoral, illegal or copyrighted content. Reverse proxies sometimes prevent access to news sites where users could view leaked information. They can also prevent users from accessing sites where they can disclose information about government or industry actions. For example, residential proxies are often used to make web scraping harder for websites to block.

  • These web proxy servers offer encryption, shield the user’s IP from targeted website administrators, and changes the outgoing IP periodically.
  • Many proxy servers are funded through a continued advertising link to the user.
  • The proxy then sends your request on to the relevant web server and forwards the response back to your device.
  • They are used to cache images and pages to reduce the load on web servers significantly.
  • They may use these proxies to enhance productivity by restricting access to websites that might distract employees from work.

In this article, we’ll define proxy servers, show you how they work, and explain how proxies and VPNs can protect you while you browse the web. As cybersecurity threats increase in sophistication and volume, businesses and users need tools to keep them safe online. HTTP proxy servers examine web traffic to identify and block malicious activity or content, what features does a proxy offer making them a highly effective option for filtering out suspicious activity. These proxies are best suited for organizations that need enhanced protection against threats that the SSL protocol reveals and stops. Because Google prefers servers that use SSL, an SSL proxy, when used in connection with a website, may help its search engine ranking.
