What Are Proxies? Your Go-To Guide in 2024

Proxies are an essential tool for anyone who wants to access the internet more securely and privately. In this comprehensive guide, I‘ll explain everything you need to know about proxies in 2024 – from what they are, how they work, the different types available, and how to choose the right proxy service for your needs.

What is a Proxy Server?

A proxy server acts as an intermediary between your device and the wider internet. When you connect through a proxy, all your traffic gets routed through the proxy server first before reaching its final destination.

The proxy sits between your device and the websites/services you‘re accessing, acting as a gateway and middleman. It mediates the connection by forwarding requests on your behalf while also receiving responses and sending them back to you.

Here‘s a simple diagram to illustrate how a proxy works:

The main benefit of this setup is that the proxy server hides your real IP address and identity. The sites you visit will only "see" the IP address of the proxy service, helping protect your privacy and anonymity online.

Proxies can also unblock geo-restricted content, let you automate tasks at scale, work around internet censorship, and more. I‘ll cover the main use cases later in this guide.

What Are Proxies?

The term "proxy" can refer to a couple of things:

• The proxy servers themselves that route traffic on your behalf.

• The proxy IP addresses you get after connecting to a proxy service.

When you use a proxy service, you essentially borrow the IP addresses of their servers. These proxy IPs allow you to mask your real IP address and location.

Proxy services have large pools of thousands of proxy servers across different countries and regions. By quickly rotating through this pool, you can make it seem like your traffic is coming from multiple places.

Some key advantages of using proxy IPs include:

• Improved privacy – Hides your real IP address which can be used to identify and track you.

• Access blocked content – Proxies from other countries let you bypass geographic blocking.

• Location spoofing – Proxies make it seem like you‘re accessing the internet from another country or city.

• Automation at scale – Rotating proxies allow you to run scraping or botting tasks without getting blocked.

• Added security – An extra layer between your device and the open internet.

So in summary, a proxy refers to both the intermediary servers as well as the IP addresses you use from those servers to mask your identity and location.

What Are Proxies Used For?

People and businesses use proxies for a number of different reasons:

1. Privacy & Anonymity

Proxies hide your real IP address, making it harder for websites or adversaries to identify and track you. They add a layer of separation between your device and your online activities.

This is useful for anyone who wants to keep their internet usage more private. Marketers and researchers also use proxies to visit competitor websites anonymously.

2. Accessing Blocked or Geo-Restricted Content

Many sites restrict content based on geographic location. For example, BBC iPlayer can only be accessed in the UK.

Connecting through proxy servers in other countries allows you to bypass these restrictions. You can unblock overseas media sites or any locally blocked content.

3. Web Scraping & Automation

Proxies are essential for large-scale web scraping and automation tasks. Scraping directly from your own IP address is a quick way to get blocked.

Rotating between thousands of proxies makes it seem like requests are coming from many different users and locations. This avoids tripping bot detections and blocks.

4. Price Comparison & Competitive Research

Businesses leverage proxies to research competitor prices and offerings across different regions. Travel sites also use proxies to scout flight and hotel deals worldwide.

By switching proxy locations, you can view how sites display content differently based on geography.

5. Ad Verification

Online ad platforms need to check that their ads are being displayed correctly worldwide. Proxies give them the ability to view ad placements from multiple geographic vantage points.

6. Enhanced Security & Anonymity

Adding a proxy on top of a VPN connection provides an extra layer of anonymity and encryption. Chaining both together makes it exponentially harder to expose your real IP address.

7. Circumventing Censorship

In countries with strict internet controls, people use proxies to bypass censorship and access otherwise blocked content. Proxies provide an opening to the unrestricted web.

8. Better Network Performance

Forward proxy servers can improve network performance for groups of users behind the same firewall. Requests get cached and served faster without leaving the local network.

As you can see, proxy servers have a wide range of applications, both for personal privacy and for business automation. Their ability to unblock regional restrictions while also rotating IP addresses makes them an extremely versatile online tool.

Proxy Server vs VPN – What‘s the Difference?

Proxies and VPNs work in similar ways, so what sets them apart?

The main differences are:

• Purpose – VPNs focus on security and encryption. Proxies specialize in unblocking geo-blocks and automation at scale.

• Connection handling – VPNs create an encrypted tunnel for all your traffic. Proxies are more configurable and can be set at the browser or app level.

• IP rotation – Proxy services provide constantly rotating IP addresses to prevent blocks. VPNs usually give you one static IP per connection.

• Anonymity level – Highly anonymous proxies completely strip all identifying headers from requests. VPN protocols like OpenVPN may still expose your real IP.

• Pricing – VPNs are generally charged as a monthly subscription fee. Proxy costs scale based on usage, so you only pay for the resources you need.

• Use cases – VPNs are great for securing your general internet access. Proxies excel at large-scale automation tasks.

So in summary:

• VPNs are better for encrypting ALL your traffic and boosting online privacy.

• Proxies specialize in managing many IP addresses for automation and bypassing geographic blocks.

Proxies and VPNs can also be used together in a layered setup for maximum anonymity.

The Main Types of Proxy Servers

There are a few different ways to classify proxy servers based on their features and network setup.

1. Forward vs Reverse Proxy

Forward and reverse proxies represent the biggest distinction:

• Forward – Forwards requests from clients out to the internet. Used to hide IP address and location.

• Reverse – Intercepts traffic heading inbound to a server. Often used for load balancing, caching, and security filtering.

Forward proxies focus on protecting client privacy and anonymity. Reverse proxies concentrate on server-side performance and security.

2. Transparent vs Anonymous vs Elite

This terminology refers to the proxy anonymity levels:

• Transparent – Does nothing to hide IP address or proxy use.

• Anonymous – Hides the originating IP but shows proxy is being used.

• Elite/High anonymous – Proxy strips all identifying headers so no proxy use is detectable. Highest anonymity.

3. Datacenter vs Residential Proxies

This classifies proxies by their infrastructure sources:

• Datacenter – Based in, you guessed it, datacenters! Very fast but easier to detect as proxies.

• Residential – Borrow IPs from real residential internet connections like homes and mobile devices. Highly anonymous.

Datacenter proxies excel at speed and reliability. Residential proxies offer higher anonymity for sites aggressively targeting datacenter IPs.

Are Proxies Legal?

Proxy services themselves are completely legal in most countries. However, proxies can obviously be used both for legal and illegal purposes.

Some people assume proxies are shady or used only by cybercriminals. This isn‘t the case. Many legitimate individuals and businesses rely on proxies to protect privacy, conduct market research, manage social media accounts, and automate data gathering.

That said, how you ultimately use proxies does matter. Activities like carding, spreading malware, hacking websites, ticket scalping etc. may breach laws as well as a website‘s Terms of Service.

When selecting a provider, you should do your due diligence in researching their reputation in the proxy space. Most well-known vendors will explicitly state their proxies are to be used for legal purposes only.

As long as you avoid shady free proxies and use them for lawful reasons, proxies are broadly legal to use in most jurisdictions. Specific laws concerning internet use, web scraping, and data protection of course vary between countries.

Are Proxy Servers Safe to Use?

Proxy services from reputable providers are safe to use. However, you need to exercise caution particularly when using free public proxy lists.

Free proxies are often of questionable quality and safety:

• They can inject ads, malware and viruses into your web traffic.

• They frequently sell user data and browsing history.

• No guarantees they aren‘t logging everything you do.

• Being used as nodes in larger botnets for malicious attacks.

• They may fail to correctly mask your IP address.

• Very slow speeds.

On the other hand, paid proxies from well-known vendors are generally very safe:

• They have contractual obligations and business reputation to uphold.

• Your usage won‘t affect others on shared plans.

• Less likely to keep extensive activity logs.

• Often based in jurisdictions with stronger privacy laws.

• Financial incentives to protect your data and anonymity.

• Offer additional security features like TLS encryption as standard.

So in summary, while free public proxies are risky, paid proxies from top providers offer excellent safety, security and peace of mind.

How Much Does Proxy Service Cost?

Proxy pricing can vary significantly based on:

• Proxy type – residential, datacenter, mobile etc.

• Anonymity level – transparent, anonymous, or elite/highly anonymous.

• Location targeting – pricing may differ based on target region.

• Plan size – costs reduce as your usage increases in larger plans.

• Bandwidth usage – some residential plans charge for traffic used.

As a rough ballpark:

• Shared datacenter proxies start from around $1 per IP address. For private IPs, expect to pay $2-5 per IP.

• Semi-private residential proxies often charge for traffic usage, starting from $5 per GB. For fully private residential IPs, ports tend to start around $50 per month.

• Mobile proxies are more costly, given their high anonymity. Expect to pay at least $30 per GB.

Remember pricing decreases significantly as your usage increases. Bulk plans can offer 3-5x cost savings over base-level pricing.

Some key things to note about proxy costs:

• You only pay for the proxy resources and bandwidth you actually use.

• Month-to-month plans offer flexibility if your usage fluctuates.

• No need to estimate upfront how many IPs you might need across a whole year.

• Easy to scale up or down. No long term contracts.

Proxy costs are very reasonable compared to VPNs or cloud computing resources. For many use cases, they offer the cheapest and most efficient solution.

How to Choose the Best Proxy Provider

With dozens of vendors offering proxy services, how do you pick the best one for your needs?

Here are key steps for choosing a reliable proxy provider:

1. Understand your usage – Consider factors like: target sites, geographic needs, tasks and scale (e.g. 10 requests per minute or 10,000?), level of anonymity required.

2. Match proxy features – Choose proxy types (datacenter, residential etc) that align with your use case requirements.

3. Check proxy location coverage – Look at number of locations available and whether they cover your target countries.

4. Review performance – Proxy speed, uptime and rate limits affect success of your tasks. Prioritize reliable performance.

5. Evaluate anonymity levels – Assess how effectively the proxies mask your identity based on their configurations.

6. Compare pricing models – Calculate costs based on your estimated usage needs; look for bulk discounts.

7. Check for essential features – Like API access, custom whitelists, integration support, etc.

8. Read trusted proxy reviews – Lean on expert reviewers to identify the top vendors.

9. Test with a trial – Take advantage of free trials or money-back periods to validate performance.

Choosing the right proxy for your specific needs takes research. But the effort pays dividends in having proxies optimized for your use cases.

How to Setup Proxies for Different Software

The process for configuring proxies varies across software and apps. Unlike VPNs, proxies require some manual setup on your end.

Here‘s a quick overview of how to get proxies working with common programs:

• Web browsers – Set manual proxy configurations in Firefox, Chrome etc under network settings.

• Scraping bots – Integrate proxies in tools like Apify, Octoparse, Scrapy by setting HTTP/HTTPS proxy lists.

• Data analytics – Import your proxy IPs into Python, R, Excel using modules like urllib or requests.

• Ad verification – Configure proxy lists inside services like AdNow, AD-Verification or SimilarWeb.

• Webhooks/automation – Add proxies to APIs and scripts using client libraries like Requests.

• Gaming/streaming – Some consoles and streaming devices allow setting custom DNS configurations pointing to proxy IPs.

• Mobile devices – On iOS or Android you can install proxy apps or manually set up proxies for wifi networks.

The best approach is to check the documentation of your specific software. Many programs make it straightforward to point your traffic through proxies.

How to Test Proxies Before Use

New proxies should always be tested before use to validate:

• Working correctly – Confirm new IPs are active and able to access the internet.

• Accessing your sites – Verify proxies work on your target websites without blocks or captchas.

• Right locations – Test geolocation to check proxies are in the countries promised.

• Sufficiently anonymous – Inspect headers to confirm anonymity level meets your needs.

• Fast enough – Speed test proxies using tools like ProxyCrawl to measure latency and throughput.

• No malware – Scan a sample of traffic through proxies to check for any malicious code injections.

Reliable proxy providers make it easy to run tests through:

• API integrations – Call API testing endpoints to vet new IPs.

• Proxy management dashboards – Tools to filter, test and monitor your proxy pool.

• Speed test tools – Like ProxyCrawl, that assess proxy latency and transfer rates.

• Free trials – Free testing periods on new accounts to validate performance before purchase.

With good technical diligence, you can feel confident your new proxies will deliver as expected for your use cases before running them at scale.
