If you’re like most people, you may think of proxy servers as a way to unblock Netflix streaming from countries other than yours or be slightly more secure when using any free WiFi network. However, the truth is that they accomplish more than that and are particularly important for companies.
Proxy servers can be described as an easy intermediary method between a PC that has an IP address private to another server that is on the internet.
A proxy server is assigned an IP address of its own, which is then made public. While it might seem like a small change, the proxy IP address is used to perform many important tasks in the business world, ranging from security to customer service.
What is a Proxy Server?
A proxy server serves as a link that connects you with the internet. It’s an intermediary service that separates users from the websites they visit. Proxy servers offer different levels of security, functionality, and privacy based on your usage scenario and requirements or policy.
If you’re using proxy servers, the internet traffic is routed through them before it gets to the website you’ve wanted. Then, the request comes back through the same proxy server (exceptions to this rule), after which the proxy server relays the information from the site to you.
Modern proxy servers can do much more than simply forwarding web requests and all for the sake of security for data and the performance of networks. They function as a firewall or web filter, offer connection to the network, and cache information to speed up the process of common requests. A reliable proxy server helps keep users and the internal network safe from harmful things found on the internet wild. Additionally, proxy servers offer a high degree of security.
Types of Proxy Servers
Forward Proxy
A forward proxy is located on top of clients and serves to transfer information to groups of users in an intranet. When a request is made, the proxy server analyzes it to decide if it should continue making connections.
A forward proxy is suitable for internal networks that require only one entry point. It offers IP address security for the users of the network as well as simple administrative control. But, a forward proxy can restrict an organization’s ability to accommodate the demands of the individual users.
Transparent Proxy
Transparent proxy gives users the same experience as the one they’d get the experience using their personal computer. This is why it’s “transparent.” They can be “forced” on users, which means they connect without realizing it.
Transparent proxy solutions are great for companies who want to utilize proxy services without telling employees they’re using one. They are a benefit of offering an uncluttered user experience. However, transparent proxy servers are more vulnerable to specific security threats, like SYN-flood-based denial-of-service attacks.
Anonymous Proxy
An anonymous proxy concentrates on making internet activity undetectable. It does this by connecting to the internet for the user while concealing their identity and computer data.
Transparent proxies are for users who want to remain completely anonymous when surfing the web. While transparent proxies offer some of the most effective security for your identity, they have negatives. Some view transparent proxy servers as a tactic to conceal their identity, and some users may encounter discrimination or pushback.
High Anonymity Proxy
High-anonymity proxy is an anonymized proxy that goes one step further. It does this by erasing your data before when it attempts to join the targeted website.
The server is ideal for users for whom privacy is essential, for example, employees who don’t want their actions traced back to their employer. However, Some of them, particularly those that are free, are decoys set up to deceive users to gain access to their personal information or information.
Distorting Proxy
A distorting proxy registers itself as a proxy for an online site but conceals its true identity. It accomplishes it by altering its IP address, thereby creating an untrue one.
Distorting proxy is a great option for those looking to conceal their location when surfing the web. This kind of proxy will appear to indicate that you’re in the country of your choice and offer you the benefit of concealing not only your identity but the identity of the proxy too. So, even if you are connected to that proxy site, your information is safe. Some websites, however, will block distorting proxies automatically, which could prevent the user from accessing the sites they’re required to access.
Residential Proxy
A residential proxy provides an IP address linked to a particular physical device. All requests are routed through the device.
Residential proxies are perfect for people who have to examine the ads on their websites, and it is possible to block cookies and unwanted or suspicious advertisements from competitors or other criminals. In addition, residential proxy services are more secure than other proxy alternatives. However, they typically cost more to use, so users must carefully examine whether they outweigh the additional expense.
Public Proxy
A public proxy is available to everyone at no cost. It gives users access to its IP address and makes it difficult for them to identify themselves when they navigate websites.
Public proxy sites are the best choice for users whose budget is a major issue, but speed and security aren’t. Although they’re available for free, they can be slow due to being overloaded with free users. If you are using an open proxy, there is also the risk of having your data available to others online.
Shared Proxy
Shared proxy services are utilized by multiple users simultaneously. They grant you access to an IP address that others could share, and you can browse the web as if to surf from a specific location you prefer.
Shared proxies can be a good alternative for people who don’t have much to spend and don’t necessarily require a high-speed connection. The primary benefit of shared proxies is their affordable cost. However, since they are shared with other users, you could be the blame for someone else’s poor decisions, and this could lead to you being banned from the site.
SSL Proxy
A secure sockets layer (SSL) proxy can decrypt data for both the server and the client. Because it encrypts data both ways, the proxy conceals its existence to both clients and servers.
These proxies are ideal for companies that require more protection from threats that SSL protocol detects and stops. Since Google prefers servers using SSL and SSL proxies, using an SSL proxy in conjunction with a site could improve the ranking of a website’s search results. On the other hand, content encrypted by an SSL proxy isn’t cached, and if you visit websites several times, it is possible to encounter less performance than otherwise.
Benefits of using a online proxy server
However, some motives to consider using a proxy web browser
1. Control internet access
This article is for all worried parents or bosses who are focused on productivity in the world. Proxy servers can monitor users’ internet access. They can be set up to block sites with content you think is inappropriate for children or distracting employees. You can also program them to record all internet requests if you want to know what your employees are doing on the internet throughout the day.
2. Enhance privacy
As previously mentioned, the proxy website alters your IP address and other information that identifies you, so your personal data remains private. The server you connect to does not know who you are, and even if they save your IP address or connection data, it will be your proxy’s browser, not the computer.
3. Access to blocked websites
Although you can use a proxy server to block employees from accessing specific websites, they could use one to gain access to blocked websites. If they are connected to the proxy server, they are able to sign in to the website that has been blocked through the browser. In addition, because their computer’s IP address will be reflected in the proxy server’s IP address, they will be able to access your blocked sites, regardless of the proxy’s limitations.
4. Increase speed and reduce bandwidth
Web proxy servers cache websites, which means they store the most up-to-date version of frequently-accessed websites. Suppose multiple employees regularly visit the same website, rather instead of retransmitting the website each time someone connects to the site. In that case, the proxy is able to easily retrieve the site out of the cache. This helps reduce bandwidth usage and increases the speed of the connection.
5. Increase security
It is possible to configure proxy servers to protect specific requests to servers. For example, many organizations use the proxy server with a VPN to protect all of their needs. In addition, proxy servers block most kinds of malware from getting access to your network or server through your connection, dramatically improving security.
How do I create a proxy server on Windows?
Here’s how you can set up your Windows PC to use a proxy server for Windows 10:
