Proxies have been around almost as long as the Internet itself, but their use has evolved over time. They were initially used primarily as a caching tool.
today, Proxy server applications It has expanded and is now an essential business tool, offering important benefits in cybersecurity, network performance, and market research.
I recently tested and reviewed it CNET’s Best Proxy Servers I took a closer, personal look at which ones are better than others. If you’re interested in using a proxy server for your business, we’ll go over some of the most popular ways you can use it to improve security, performance, and competitive intelligence.
Enhancing cyber security
One of the main reasons a company uses a proxy server is to protect its employees’ data and improve its corporate security. A proxy server basically acts as a barrier between the company and the outside world.
where Most proxy servers Traditionally, your traffic is routed through another IP address upon exit, and these reverse proxy servers are located in front of web servers to manage incoming traffic. This is a particularly attractive option in corporate environments where companies want… Protect their internal networks.
“Corporate environments that have websites don’t want to expose those IP addresses, so they’ll have a reverse proxy on the front end of that so that a source trying to access those servers can’t see the server address,” he said. Eric Avakiana technical consultant at Info-Tech Research Group and former chief information security officer for the Commonwealth of Pennsylvania.
Using this Agent service typer can offer other cybersecurity benefits to businesses, including encryption and decryption of SSL or Transport Layer data. Doing this for each individual client can be expensive and resource-intensive.
A reverse proxy allows businesses to offload some of this computationally intensive work off the server and onto the proxy itself.
Improve performance and save bandwidth
In addition to security use cases, proxy servers can also improve network performance for businesses by storing frequently accessed web pages and files. These resources are stored locally instead of the original source. This is especially useful for companies with large employee bases, as it can reduce loading times, latency, and bandwidth consumption.
Another major benefit here is load balancing. This allows companies to distribute traffic around multiple back-end servers, rather than routing it all through a single server. With this type of setup, companies also have added protection against site downtime, as traffic can be redirected to a different server in the event of an outage or network attack.
Staff management and content monitoring
Proxies can protect companies in both ways: by restricting incoming content within their walls and hiding their employees’ IP addresses when they go out. The first method is essentially a way to control the types of content that employees can access from their company network.
“Companies use proxies to restrict Internet traffic from their end users,” Avakian said. “Businesses may want to block certain types of websites.”
In addition to filtering content, proxy servers set up on a company’s network will also protect the company by masking its IP addresses. If an employee accesses a malicious website, a proxy server can reduce the amount of information accessible.
“The traffic doesn’t appear to be coming from your computer. It’s coming from the proxy,” Avakian said. “Companies don’t want people online to see their IP addresses, so they’ll put them through a proxy first.”
Social media management
Proxies are often used to avoid blocking when too many requests are sent from a single IP address, and social media platforms are among the main use cases.
Most social media companies allow about five accounts per IP address, and excessive activity from a single IP address can result in a ban or suspension from platforms like Instagram, Facebook, or TikTok.
“A lot of people use agents to manage 30 different social media accounts,” Avakian said. “Some social media companies restrict this, but if you use proxies, you will be able to do it.”
But agents aren’t just useful for businesses looking to manage multiple accounts. They can also help collect market research data. With many companies using location-based marketing strategies, proxies give them the ability to change location to access content available in different regions. They also allow web aggregation at scale across social media platforms.
Many proxy companies offer specific tools to collect social media data. I was particularly impressed Decryptionwhich comes with pre-made scraping templates.
Web scraping
Web scraping is the most common commercial use case for proxies, and offers several advantages. As with social media platforms, many websites prohibit web scraping requests from a single IP address.
Proxies are the primary solution to help businesses circumvent this. One feature that caught my attention during the review Oxylabs proxy servers Its advanced web scraping tools allow you to collect data in large quantities without getting banned.
“Let’s say you’re trying to extract data from your competitor’s site. Maybe it’s pricing data. You’re basically doing research,” Avakian said. “You don’t want it to look like you’re collecting it all from one source, because it will probably get blocked.”
Proxy servers also allow you to change the location of the IP address making the request, so you can collect or bypass local data in specific markets Geo-restricted content.
takes Internet service providersFor example. Many ISPs vary their rates based on location. If you want to gather information about how much your competitors are charging for plans across the country, many proxy servers will allow you to choose locations down to the zip code level.
Keep in mind that this type of solution may violate the website’s terms of service. The legality of web scraping is complex, and I am not in a position to provide legal advice on this matter. but this post From the law firm Quinn Emanuel provides some useful background information.
“Web data scrapers and those hosting or relying on stolen personal data should be aware of all applicable privacy regulations governing their activity and seek legal advice to ensure they comply with these regulations,” the company says.
| Main benefit | feature | Disadvantages/Risks |
|---|---|---|
| Enhancing cyber security | IP anonymization, malicious content filtering and encryption. | The only point of failure is privacy concerns with third-party providers. |
| Improve performance and save bandwidth | Store frequently used data, reducing access time and load balancing. | Potential performance, cost and complexity bottlenecks. |
| Staff management and content monitoring | Web filtering and activity monitoring. | Privacy concerns for employees. |
| Gain a competitive advantage | Geo-targeting, localization, web aggregation (market data and pricing) and bypassing geo-restrictions. | Legal and ethical concerns; Privacy concerns with third-party providers. |
Reasons why the company does not want to use an agent
Although proxies offer many advantages, there are several reasons why a company may choose not to use one:
- Cost and complexity: Proxies can be expensive, with many starting at around $4 per GB, and require some technical proficiency to set up and use. If you don’t have a dedicated IT professional on your team, there may be a bit of a learning curve to get started.
- Potential performance bottlenecks: Although proxies can give you performance improvements through caching, they can also slow down your internet speed as traffic is routed through a separate server.
- The only point of failure: If you use a single proxy server for security or content filtering, you run the risk of the entire network crashing if there is a problem with the proxy server. This can be mitigated by using multiple proxy servers with automatic failover.
- Privacy concerns with third-party providers: Web scraping violates some websites’ terms of service, and using a proxy server to get around it may expose you to legal liability. When in doubt, consult an attorney to ensure you comply with legal regulations.
Bottom line
Proxies have a number of legitimate use cases for businesses, from cybersecurity protection to market research. Before signing up for a proxy server, it is important to know what kind of activities you need, how many IP addresses you will need, and which tools will be useful for your business.
