VPN vs Proxy: Let’s first discuss the differences between a proxy and a VPN. You may want to know their similarities, which is likely why you’re here. You’re aware of their shared traits, but you’re uncertain about which direction to choose.
What similarities do VPN vs Proxy share?
VPN servers and proxy servers address the issue of decentralization in distributed networks. Accessing a central network over public networks, such as the Internet, can be risky without VPNs and proxies. These tools provide a secure way to connect and protect data.
Anonymity or privacy
Proxies and VPNs were not initially designed for privacy, but they do offer a level of anonymity.
A VPN and a proxy securely connect distributed networks over risky networks, such as the Internet, and offer Internet privacy. It’s perfect for getting around censorship, accessing blocked streaming content, or using P2P networks securely.

1. VPN vs Proxy: Original Design
Virtual Private Network (VPN)
VPNs were initially designed for a different purpose than their current usage. Initially, these were designed for big organizations with extensive networks, such as universities or enterprises. The goal was to provide secure access for distributed and remote users and branch offices to sensitive data within an internal network. Connecting these remote users with a wire was impossible, so a VPN was used to leverage existing infrastructure, such as the Internet. However, VPNs implemented tunneling with encryption to ensure the security of remote users and internal networks when transmitting data over public networks. This made the message impossible to comprehend.
Proxy
Proxies were initially developed to simplify distributed networks by using a centralized server. They were created to act as go-betweens for multiple networks. They redirect requests from clients in one network to a server in another network. Proxies can modify application-level requests or responses, including HTTP, SSL, FTP, and more.
2. VPN vs Proxy: How They Work
Virtual Private Network (VPN)
VPNs utilize a client/server communication model and operate at layers three (L3) and above of the OSI model. The VPN client can be your computer or mobile device, which securely encrypts your traffic using a private encryption key. The VPN server knows the key, allowing it to decrypt incoming messages. Various entities, such as the Internet, public WiFi, your ISP, CDNs, and anything in between, can still monitor your online activity. However, they will need help understanding the content of your traffic.
VPNs use protocols such as OpenVPN, L2TP, SSL, and IPSec, which employ strong encryption mechanisms like AES-256.
Proxy
Proxies can function at different OSI model layers, such as layer four (TCP/UDP) or layer seven (HTTP/HTTPS, SOCKS). Like a VPN, a proxy is commonly known as the server rather than the network. Proxies differ from VPNs because they don’t encrypt traffic and don’t require any configuration on the client side. You only need an IP or route information to locate the proxy server. The proxy server is responsible for forwarding requests and responses, and in certain situations, it may also modify, block, or log them.
3. Proxy vs VPN: Use Cases
Virtual Private Network (VPN)
Due to their encryption mechanisms, VPNs are highly effective in securing Internet connections. They are commonly used to ensure secure remote access and provide protection against malware and hacking when browsing the internet. VPNs provide a range of benefits, including maintaining online privacy, bypassing censorship and network restrictions imposed by governments, ISPs, or institutions, and unblocking geo-restricted content. They are also useful for P2P activities and more.
Proxy
Proxies offer a different approach to ensuring online anonymity. Proxies are simple to use, speedy, affordable, and often available at no cost. They are widely used to bypass censorship, access geo-restricted content, download torrents, and stream geo-restricted content.
Proxies shine in bulk, particularly for tasks such as web scraping and large-scale SEO campaigns.
4. Proxy vs VPN: Privacy Comparison
Virtual Private Network (VPN)
As stated earlier, VPNs utilize encryption to ensure privacy. While there are less strong encryption mechanisms that can be decrypted, it is still preferable to have some form of encryption rather than none at all. However, a VPN is not a foolproof solution. Certain vulnerabilities in VPN technology can result in data leakage when using IPv6, WebRTC, and, in certain instances, DNS.
Avoid using free VPNs, as they often compromise your privacy by tampering with your personal logs and data. Your bandwidth could be sold without your knowledge.
Proxy
Proxies do not provide data encryption. Instead, they conceal your original IP address using the proxy server’s IP address. With different types of proxies, the destination of your request won’t be able to identify the source (IP) as everything will be traced back to the proxy. The proxy provider is responsible for deciding whether to encrypt traffic logs or delete them, considering the information they have about your source IP and request.
Avoid free proxies, which can compromise your data and infect your devices.
5. VPN vs Proxy: Speed
Virtual Private Network (VPN)
VPNs encrypt traffic, resulting in higher overhead, particularly with protocols like OpenVPN, which prioritizes privacy over speed. VPNs are not commonly used to enhance speed, particularly for activities such as torrenting and streaming. VPN providers can improve speed by utilizing a vast network of servers located worldwide and deploying VPNs in high-speed data centers.
Proxy
Proxies do not encrypt traffic, which helps to maintain a high level of performance and speed. However, there are concerns regarding the compromise of security and privacy. Proxies are commonly used for tasks that demand quick performance, such as data scraping, torrenting, streaming, and more. SOCKS5 proxies are considered secure due to their authentication integration and lightweight nature.

Final Words
Which is better, a VPN or a proxy?
It will vary based on what you need and what you have available. Understanding the initial design of each technology can provide a reliable foundation for knowing what to anticipate. VPNs are an excellent solution for ensuring secure access to internal networks, even when connected to risky networks. On the other hand, proxies help centralize requests and offer a level of control or anonymity over those requests.
Both technologies have a wide range of applications. VPNs are more effective for securely transmitting sensitive data across untrusted networks. When relying on a coffee shop’s WiFi, it’s essential to use a VPN. Proxies, however, are ideal for tasks that necessitate a balance between speed, anonymity, and affordability when altering your IP address. Consider using IP rotating proxies for data scraping, market research, and large-scale SEO campaigns.
