Proxy vs. VPN: Which Offers Better Online Privacy?

Every click, every search, every post leaves a trail of data. From your browsing history to your location, a wealth of personal data is up for grabs. 

Whether you're shopping, streaming, or just browsing, keeping your data secure should be a top priority. That's where a Virtual Private Network (VPN) and proxy server come into play. 

Both offer ways to shield your internet activity from prying eyes, but they do it differently.

But which one is right for you? Let's find out. 

Whether you're aiming for top-notch security or want a bit more privacy, we've got you covered. Keep reading to make the intelligent choice for your online protection!

What is a proxy server?

A proxy server acts as an intermediary between you and the websites you want to visit, creating a layer of separation between your device and the internet.

When you browse online, your internet traffic first goes through the proxy server, which then connects you to the actual website, also known as the host server. This process masks your real IP address, making it seem like you’re browsing from a different location.

For example, if you’re browsing the internet in downtown Chicago and you come across a website that is geographically restricted to people who only live in Europe, you can connect to a proxy server located in Italy and then browse that website as you please.

Types of proxy servers

A proxy server operates through one of three different types, each with its own specific function and level of privacy.

1. HTTP proxy

The oldest type of proxy server is the HTTP proxy, which is specifically designed for web pages and web-based traffic.

When setting up a browser with an HTTP proxy, you plug the proxy server into your web browser’s configuration file. You can also use a browser extension if your browser doesn’t support proxies. Then, all of your web traffic is routed through the remote proxy.

This type of proxy is most useful for web browsing and accessing websites that are restricted based on geographical locations.

2.  Socket Secure (SOCKS) proxy

A SOCKS proxy isn’t limited to web traffic, but it still works only on the application level. It’s a useful extension of the HTTP proxy system because it’s indifferent to the type of traffic that connects through it.

This type of proxy can be set up on a game, video streaming app, or peer-to-peer (P2P)  platform. The downside of SOCKS proxies is that they are typically slower than HTTP proxies since they’re more popular and have a higher load.

Like HTTP proxies, they don’t provide users with encryption. 

3. Transparent proxy

As the name suggests, a transparent proxy is a proxy that a user is unaware of. You may not even know that your traffic is being routed through a transparent proxy since it’s basically invisible.

Additionally, these proxies don’t modify any of your information, like your IP address, so the request to the destination server (the website you’re visiting) will show it’s coming directly from you.

You may be wondering what the point of a transparent proxy is. They’re typically set up by employers or parents who want to monitor online activity and block access to specific websites.  You are able to create whitelists and blacklists for users, which would allow an employer or school to block social media websites during working hours.

Public vs. private proxy servers

The different functions and features of a proxy server can also depend on whether it’s private or public.

A public proxy server, sometimes referred to as an open proxy server, is a proxy that anyone can use. Such proxies can handle thousands of connections at the same time, making this possible.

Public proxies, including HTTP and SOCKS proxies, are free to use. However, they tend to be unstable and can sometimes be overloaded and stop functioning. Your connection could drop, and the speed could be relatively slow.

A private proxy server won’t be available for everyone, and you’ll need to buy one to be able to use it. You’ll also need a username and password, and because it’s private, it's much faster and boasts a stronger connection than public proxies.

Benefits of using a proxy 

Using a proxy server offers several key benefits while you browse the web, including:

• Anonymity: A proxy server hides your IP address, allowing you to browse the internet anonymously.
• Bypassing restrictions: Proxies help you circumvent web restrictions and keep your online activity private.
• Access to geo-blocked content: With a proxy, you can access services and websites that are restricted to specific regions.
• No extra software needed: You can use a proxy without the hassle of downloading or installing additional software.
• Cost-effective browsing: Many proxies are available for free, making them a budget-friendly option for enhancing your online privacy.

Drawbacks of using a proxy 

Using a proxy server also has some notable drawbacks:

• Lack of privacy: Your web traffic is visible to the proxy server owner, which can compromise your privacy.
• Limited configuration: Proxies are often set up for specific browsers or applications, not for the entire network.
• No encryption: A proxy does not encrypt your data, leaving it vulnerable to interception.
• Risk of malware: Proxies can expose you to malware and other security threats.
• Potential for slow speeds: When a proxy server is used by many people, connection speeds can slow down. To avoid this, you may need to invest in a private proxy server.

What is a VPN?

Like a proxy, a VPN will reroute your internet traffic using a remote server that hides your IP address so websites can’t see your original IP or location. What it does differently, is that it encrypts your information and secures 100% of your movements as you use the internet. 

The added step of encryption means you get the benefit of data security and privacy in addition to anonymity. Because of this, data within your online banking apps or credit score websites are secure through a VPN, whereas they would still be vulnerable to hackers with a proxy.

A VPN also works on the operating system level instead of the application level, which means it redirects all traffic regardless of whether it comes from your browser or a background application.

Types of VPNs

There are two basic types of VPNs. Which one you use will depend on your needs.

1. Remote access VPN

A remote access VPN allows a user to connect to a private network and access all of its services and resources while being remote.

The connection between the user and the private network is created through the Internet, allowing it to be completely private and secure. This type of VPN is typically useful for both home and business users.

For instance, a user browsing at home can use a VPN to bypass any regional restrictions on the internet and access blocked websites. An employee of a company who is currently working remotely can use a VPN to connect to their company’s network, allowing them to access files and resources on a private network.

2. Site-to-site VPN

A site-to-site VPN also referred to as a router-to-router VPN, is used mostly by large companies or organizations with offices in different locations.

It allows these companies to connect the network of one office to the network of another office. Think of this as an imaginary bridge between the two networks that connects them to the Internet while remaining a secure and private connection.

When a site-to-site VPN is used, one router acts as the VPN client, and another router is used as a VPN server since this type is based on router-to-router communication. When authentication is complete between the two routers, communication can begin.

Benefits of using a VPN

Choosing a VPN offers several key advantages:

• IP address masking: A VPN hides your IP address and assigns you a new one, enhancing your anonymity online.
• Secure public WiFi: A VPN allows you to safely use public WiFi networks without risking your data.
• End-to-end encryption: VPNs use strong encryption to secure your data and protect it from unauthorized access.
• Access to geo-blocked content: With a VPN, you can bypass geographic restrictions and access content and services that are blocked in your region.
• Automated privacy: A VPN automatically maintains your anonymity and privacy while you browse the web.
• Comprehensive security: Once installed, a VPN ensures that all internet activity on your device remains secure and anonymous.

Drawbacks of using a VPN

Using a VPN has many benefits, but there are also some drawbacks to consider:

• Cost: VPNs are not free, so you’ll need to pay for a reliable service provider.
• Speed reduction: You might experience a decrease in browsing speed while using a VPN.
• Variable security: The level of security provided by a VPN depends on the quality of the software, so it’s important to research and choose a reputable VPN service.

What should you use, a proxy or a VPN?

Now you know that both a VPN and a proxy will block your IP address. While a proxy acts as a gateway and is ideal for basic web functions, a VPN is what you’ll want to use when you need an extra layer of security for your internet use and data.

Here's a summary of key differences between the two that you’ll need to be aware of when choosing.

Unfortunately, there isn’t a black-and-white answer to whether or not you should use a proxy or a VPN. 

When to use a proxy

Now that you have a clearer understanding of what a proxy is and the types available, you might wonder when it's best to use one. The ideal scenarios for using a proxy include:

• Bypassing firewalls or geo-blocks: If you need to access websites that are restricted by firewalls or geo-blocks.
• Non-sensitive browsing: When you’re not transmitting sensitive information and just need to surf the web.
• Reducing bandwidth: If you want to cut down on bandwidth usage while browsing.
• Streaming region-restricted content: When you’re interested in watching content that’s only available in certain regions.
• Playing games with limited anonymity: For gaming where full anonymity isn’t critical.
• Using older systems: When you're on an outdated operating system that limits available software.
• Parental controls: If you’re a parent looking to filter out inappropriate content for your children.

When to use a VPN

In contrast, a VPN offers more comprehensive protection and is the preferred choice in several situations:

• Secure logins: When browsing the web and logging into accounts, a VPN helps protect your credentials.
• Public WiFi security: If you're using an unsecured public WiFi network, a VPN secures your connection.
• Navigating censorship: When living in a country with internet censorship and online surveillance, a VPN can bypass these restrictions.
• Accessing region-restricted content: For accessing entertainment or other content restricted to specific regions.
• Protecting sensitive information: When working with sensitive data, like usernames and passwords.
• Preventing data theft: If you’re concerned about insider threats and data breaches, a VPN provides stronger security.
• Safeguarding personal privacy: In any situation where maintaining your privacy is crucial.

Frequently asked questions on proxy servers vs. VPNs

Q. Can I use a free proxy or a free VPN?

Free proxy software can offer basic functions like masking your IP address and bypassing geo-blocks, but they don’t provide encryption and may expose you to security risks. Free VPN solutions offer encryption and better overall security, but they may have limitations, such as slower speeds or data caps.

Q. Do I need a proxy if I have a VPN?

If you have a VPN, you generally don't need a proxy, as a VPN already provides enhanced privacy and security by encrypting your internet traffic and masking your IP address. Unlike a proxy, which only hides your IP address.

Q. Can I use a VPN and proxy together?

You can use a VPN and a proxy together, but it requires additional configuration and is generally not recommended. Adding a proxy server on top of a VPN introduces another layer of middlemen, which can slow down your internet connection without providing significant additional benefits.

Knock knock: what is the key to your security?

In the ongoing debate between proxies and VPNs, it’s evident that each has its own distinct advantages and uses. The decision between using a proxy or a VPN depends on your specific needs and the level of security you require.
