When shopping for [proxies](https://marsproxies.com/blog/are-proxies-safe/), you will likely come across various types. Examples include [residential proxies](https://marsproxies.com/proxies/residential-proxies/), [datacenter](https://marsproxies.com/proxies/datacenter-proxies/), transparent, rotating, HTTP, HTTPS, and even SOCKS proxies. To make the right choice, **you should understand how each proxy server functions and the factors that set them apart.**

That way, you will know the situations where, for example, an [HTTPS proxy](https://marsproxies.com/other-proxies/https-proxies/) server is ideal and when a SOCKS5 proxy is better. **Today's blog takes a deep dive into SOCKS proxy servers**. By the end, you will have gained insights into:

- How SOCKS proxies work

* The difference between SOCKS proxy servers and other proxy types

- The difference between SOCKS4 and [SOCKS5 proxies](https://marsproxies.com/blog/best-socks5-proxy-providers/)

- And much more

Join us below.

## What Is a SOCKS Proxy?

SOCKS stands for Socket Secure. It's a protocol that facilitates network communication through proxy servers. You've probably heard of HTTP/HTTPS proxies, known for handling HTTP(S) traffic. **A SOCKS proxy is superior to HTTP and HTTPS proxies because it can handle all types of internet traffic.** You can browse the web, send [emails](https://marsproxies.com/blog/email-proxy/), [download torrents](https://marsproxies.com/other-proxies/rarbg-proxy/), and even play online games with your friends.

## SOCKS Proxies vs. Other Types of Proxies

Let's expand on SOCKS proxy addresses by comparing them with other types of [proxy servers](https://marsproxies.com/blog/how-does-a-proxy-server-improve-security/) based on protocol support, security anonymity, and performance. Keep scrolling below for full details.

### Protocol Support

#### SOCKS Proxies

- Work at a lower level than HTTP and HTTPS proxies—**the **[**transport network layer**](https://www.techtarget.com/searchnetworking/definition/Transport-layer#:~:text=The%20transport%20layer%20is%20Layer,User%20Datagram%20Protocol%20\(UDP\).). This allows them to relay all types of traffic without much modification.

* **They can handle all types of web traffic**, including HTTP/HTTPS, FTP, peer-to-peer file sharing, email services, VoIP, and [gaming](https://marsproxies.com/use-cases/gaming-proxies/) traffic.

#### HTTP/HTTPS Proxies

- They only transmit HTTP and HTTPS traffic.

* Unlike SOCKS proxies, they **cannot handle non-web traffic.**

### Security and Anonymity

#### SOCKS Proxies

- They offer **better security and anonymity** because SOCKS does not modify packet headers.

* You can use authentication **(only for **[**SOCKS5 residential proxies**](https://marsproxies.com/other-proxies/socks5-residential-proxies/)**)** and **encrypt** the connection.

#### HTTP/HTTPS Proxies

- [HTTP proxies](https://marsproxies.com/blog/http-proxy-meaning/) are** less secure** because they relay data in plain text.

* **HTTPS proxies encrypt data**, making them more secure than HTTP servers.

### Performance

#### SOCKS Proxies

- They can be slower because of the **broad protocol support.**

* **SOCKS5 **[**fast proxies**](https://marsproxies.com/other-proxies/fast-proxies/)** are more versatile** in handling large amounts of diverse traffic.

#### HTTP/HTTPS Proxies

- [**HTTP proxies**](https://marsproxies.com/blog/what-is-http-proxy/)** may be faster **because they are optimized for HTTP traffic.

* Despite being more secure, HTTPS proxies can be slower because of **encryption overhead**.

## The SOCKS Protocol: SOCKS4 vs. SOCKS5 Proxy

With the foundation of SOCKS well laid out, you understand how they compare to other types. Let's take a closer look at the SOCKS protocol by looking at the two known versions: **SOCKS4 and SOCKS5**.

### What Is SOCKS4 Proxy?

SOCKS4 is a basic version that allows clients to connect to servers over a TCP connection. **This protocol only supports regular web traffic, so no emails, **[**torrents**](https://marsproxies.com/other-proxies/torrent-proxies/)**, or anything like that**. It also does not support authentication, meaning you can't provide special access to select users.

Again, it's the basic SOCKS protocol. There's no advanced security or encryption as you would expect from a [SOCKS5 proxy](https://marsproxies.com/blog/firefox-socks5-proxy/). So, the **SOCKS4 protocol is helpful for basic, low-level browsing.**

### What Is SOCKS5 Proxy?

As you may already suspect, SOCKS5 is an updated version of SOCKS4. **A SOCKS5 proxy gives you everything that a SOCKS4 proxy doesn't.** For one, they support both TCP and UDP connections. You can use them for web browsing, emailing, and file downloads.

A TCP connection ensures that the data transmitted between your device and the proxy is intact without any error. On the other hand, **UDP skips error checking and retransmissions, transmitting data much faster.** It is ideal for situations where speed is more important than reliability, such as video streaming, online gaming, and voice calls.

A SOCKS5 proxy also supports authentication, allowing you to restrict proxy server use to authorized users only. On top of that, **SOCKS5 proxies can handle **[**DNS resolution**](https://www.datadoghq.com/knowledge-center/dns-resolution/)** at the proxy server level.** This offers an extra layer of privacy in addition to hiding IP. By handling your DNS lookup instead of your ISP, as is the norm, [ISPs](https://marsproxies.com/blog/isp-vs-residential-proxies/) cannot know the websites you visit.

## Pros and Cons of Using SOCKS Proxies

Here are the advantages of using Socket Secure proxy servers:

- **Versatility and performance**

As you know, a SOCKS [proxy server](https://marsproxies.com/blog/how-to-find-your-proxy-server-address-step-by-step-guide/) can handle all types of internet traffic. This makes it a one-size-fits-all solution for many different use cases, including web scraping.

- **Anonymity**

Apart from masking a user's IP, **SOCKS IPs don't alter the information that passes through them**. This makes them better at anonymity than HTTP/HTTPS. They also suit users who prefer direct, undisturbed data routing for applications like emailing, FTP, and P2P traffic.

- **Bypass geo-restrictions**

SOCKS proxies are also **suitable for bypassing geo-restrictions, censorship, and firewalls** because they mask your real IP address. They can access content that might be restricted in certain regions, such as streaming platforms like Netflix. For a dedicated comparison of streaming-optimized options, see our guide to the best [online video streaming proxy](https://marsproxies.com/blog/best-proxies-for-streaming/).

- **Improved security with a SOCKS5 proxy server**

**A SOCKS5 proxy supports authentication, encryption, and DNS handling**, ensuring better security when sending requests. With these features, you can restrict proxy usage to select users, ensure data is unreadable during transit, and prevent ISPs from seeing the websites you visit.

SOCKS proxies are not without their downsides, though. Here is what to expect:

**Slower speeds**

They tend to be slower than HTTP/HTTPS servers because of the** additional processing power needed for the diverse traffic types it supports and features**. Authentication and encryption, while they boost security, can also reduce the speed of the proxy server.

- **No built-in encryption in SOCKS4 proxies**

**SOCKS4 proxies don't have any encryption or security mechanism**. This can expose data to unauthorized access during transmission. For this reason, you should enforce additional safety features, such as SSL/TLS encryption, for better security.

- **Complex setup**

The process of configuring a SOCKS proxy can be more complex than HTTP/HTTPS servers in case you need to **set up specific software and applications to work with SOCKS.**

## SOCKS Proxy vs. VPN: Which One Should You Choose?

The choice between a SOCKS5 proxy and a VPN can be a tough one. You might think they do the same thing, and they do. **Both options hide your IP**. What’s the difference then? They do it in very different ways.

**A proxy acts as a middleman between your device and the internet. **It reroutes your traffic through its server’s IP. **A VPN, on the other hand, creates a secure tunnel between your device and the VPN server**, which will route your traffic to the target via an alternate IP.

So then, what’s the better option for you? We’ve put them side by side below, analyzing the features they offer:

## How to Set Up a SOCKS Proxy Server on Different Platforms

### Windows Setup Guide

- Step 5: Click Save to save your proxy profile

* Step 6: Click on the **extension icon **again, find your proxy profile, and click the **Connect** button to start using it

## How to Choose the Best SOCKS Proxy Provider?

If you did a quick Google search using the terms "SOCKS proxy," you would be bombarded by hundreds of companies all claiming to offer top-tier service. **Making a choice here can be difficult, depending on your needs and other factors.** For example, proxies for web scraping need a different set of features from those you plan to use for streaming or gaming.

Start by considering the pricing. Which companies offer SOCKS proxies that are within your price range? Next, look at the features—do they offer a good uptime guarantee? **What kind of geo-targeting and session control do they support? **How about the performance benchmarks? How fast are their proxies? And do they log user traffic?

You can also log on to user review platforms like G2 and Trustpilot. It’s always a good idea to see what people say about a particular provider before taking out your credit card.
