In the era of online privacy, two tools are often mentioned together: VPNs and proxies.
Both hide your IP address and help you browse the Internet more privately, but they work in different ways and serve different purposes. From simple security to web scraping for LLM training, both serve different purposes for businesses.
If you’ve ever wondered which one you should use, this article will help you understand how they work, their key differences, and where residential proxies fit into the picture.
What we will cover
What is VPN?
a Virtual private networkor VPN, is a service that creates a secure and encrypted tunnel between your device and the Internet.
When you connect to a VPN, all of your traffic goes through a remote server run by the VPN provider. It hides your real IP address and encrypts everything you send or receive.
VPNs are often used by people who want to protect their privacy or access content restricted in their region.
For example, someone in India can use a VPN to connect to an American server and access websites that are only available in the United States. Because the connection is encrypted, Internet service providers and hackers cannot see what websites you visit or what data you exchange.
What is a proxy?
a Proxy Acts as an intermediary between your device and the Internet.
When you connect to a proxy, your request is first sent to the proxy server, which then forwards it to the target website. The website sees the proxy’s IP address instead of your own.
Unlike VPNs, proxies usually don’t encrypt your traffic. This means that while your IP address is hidden, the data may still be visible to others.
Proxies are often used for tasks such as web scraping, managing multiple social media accounts, or accessing geo-restricted sites in a lightweight manner.
There are different types of proxies, such as data center proxies, mobile proxies and residential proxies. Among them, Residential proxy Most are reliable because they use real IP addresses assigned by Internet service providers.
The main difference between VPNs and proxies
The biggest difference between a VPN and a proxy is encryption.
VPNs encrypt all network traffic from your device, while most proxies do not. This means that VPNs provide a high level of security and privacy. Even if someone intercepts your data, they can’t read it.
Proxies, on the other hand, focus more on IP masking than full encryption. They are lighter, faster, and more flexible for specific use cases such as automation, scraping, or material testing.
For example, a company that needs to collect product data from multiple e-commerce sites would use a residential proxy instead of a VPN because a proxy allows scalable, distributed access from different IP addresses.
Another important difference is the level of system-wide protection. A VPN Encrypts all traffic coming from your device, including background apps.
A proxy usually only routes traffic from specific browsers or applications. This makes VPNs better for personal privacy and proxies.
Performance and speed
Because VPNs encrypt traffic, they can slow down speeds due to the extra processing involved. Proxies, in contrast, are often faster because they skip encryption and only route specific requests.
However, not all proxies are equal. Data center proxies can be fast but easy to detect, while residential proxies are slower but far more reliable for tasks that require realism. Businesses often accept this small trade speed for better accuracy and less blocking.
VPNs typically have fewer IPs and servers than proxy networks, which can limit their flexibility. The proxy can automatically rotate thousands of IPs, which helps avoid blocking and distribute requests efficiently.
Use cases for VPNs
VPNs are ideal for individuals who value security and privacy. They are useful for browsing securely on public Wi-Fi, accessing restricted websites, or hiding browsing habits from Internet service providers.
Remote workers often use VPNs to securely access corporate networks. Journalists and activists rely on them to bypass censorship or protect communications in restricted areas.
For everyday users, a VPN provides an easy and effective way to browse anonymously and encrypt all data traffic.
Use cases for proxies
The proxy shines in automation and business scenarios. They are essential for data collection, web scraping, and digital marketing. By using resident proxies, companies can collect information from multiple websites without being blocked.
For example, a brand can track how its ads appear to consumers in different countries. E-commerce businesses can compare competitor prices or monitor product inventories in real time. Social media managers use proxies to manage multiple accounts without triggering platform restrictions.
Proxies also help a lot Web Scraping for LLM Training. They allow businesses to collect public data anonymously and at scale without being blocked or throttled by websites.
How to combine VPNs and residential proxies
In some cases, professionals use both. For example, a researcher can connect to a VPN for encryption and then perform specific scraping tasks along the way through resident proxies for location diversity. This hybrid setup balances privacy and data collection efficiency.
Combining them also reduces the risk of IP restriction. If a target site starts blocking one set of IPS, the user can switch networks seamlessly. This approach is popular in cybersecurity testing, AD validation, and large-scale monitoring.
Which should you choose?
If privacy is your goal, use a VPN. It secures your entire connection and hides all your online activities. If your goal is automation, data collection, or region-specific testing, use a proxy.
Resident proxies are especially effective when websites have anti-bot protection or region-based restrictions. They combine anonymity with authenticity, making your traffic look like a regular home user.
For individuals who need both security and flexibility, a combination of VPN and proxy may work best. You can encrypt your connection with a VPN and use resident proxies for specific tools or scripts that require rotation and scale.
As online tracking becomes more advanced, tools like VPNs and resident proxies are becoming essential for both individuals and businesses. Companies use them to access unbiased market data and protect digital assets. do, while individuals use them to browse safely and privately.
In the future, we may see hybrid solutions that combine the privacy of VPNs with the scalability of proxy networks. These systems can automatically switch between encryption and proxy routing on a task-by-task basis, providing a smooth balance between speed and security.
The result
VPNs and proxies both protect your identity online, but they serve different purposes. VPNs focus on privacy and encryption, while proxies, especially residential proxies, focus on scalability and accessibility.
Understanding each function helps you choose the right tool for your needs. Whether you want to stay anonymous, collect data securely, or check websites from different countries, using the right combination of VPNs and resident proxies can give you both privacy and power in the digital world.
