Proxy vs. VPN: What’s the Difference and Which Should You Use?

The main difference between a proxy and a VPN is how they actually work. A proxy acts like a gateway for your internet connection, while a VPN routes your traffic through an encrypted tunnel. Both proxies and VPNs are a great option to help maintain privacy and security while online. Let’s dive deeper into the core differences between proxies and VPNs, how each works, and when to choose one over the other.

Proxy vs VPN: Pros and Cons at a Glance

What is a Proxy Server?

A proxy server acts as an intermediary between your device and the internet. When you access a website through a proxy, the request is routed through the proxy server, which sends it to the destination site. The site only sees the proxy server’s IP address, not your actual IP address. While using a proxy server is generally suitable for everyday browsing, it does not offer the same level of security that a VPN does. 

The Different Types of Proxies

1. HTTP Proxies: Primarily used for web browsing, HTTP proxies only handle web traffic. These are helpful for bypassing restricted sites or accessing geo-blocked content on specific websites.
2. SOCKS Proxies: SOCKS proxies support various traffic types, like video streams and torrents, making them more versatile than HTTP proxies. However, they don’t offer encryption, so your data is still vulnerable to snooping.
3. Transparent Proxies: Used mostly by organizations to control internet usage or filter content, transparent proxies don’t hide your IP address and are often invisible to the user.

The Different Uses of Proxies

We already know that proxies use a variety of different protocols, like SOCKS or HTTP. Now let’s take a closer look at the different types of use cases that people use proxies in the real world for. Some examples are:

Shared Proxy:

• Used by multiple users simultaneously.
• May be less secure and slower because resources are shared.
• Often cheaper and can be useful for low-priority tasks.

Public Proxy:

• Free proxies available publicly.
• Usually unreliable, less secure, and may have high traffic loads.
• Useful for occasional tasks where privacy and speed aren’t a priority.

Forward Proxy:

• A generic proxy that acts as an intermediary between the client and the internet.
• Allows users to bypass restrictions or improve privacy, controlling access to the web.
• Often used within corporate networks to control access or optimize bandwidth.

Residential Proxy:

• Uses IP addresses assigned to residential homes, making traffic appear as though it’s coming from a regular user.
• Very reliable for evading detection, making them ideal for activities where anonymity and IP-based trust are essential.
• More expensive but often the most reliable and trusted type.

The Advantages and Drawbacks of Proxies

Like many things in modern digital technology, there are tradeoffs between different services. Use of proxies is no exception to that rule, here are some of the advantages and disadvantages of using a proxy over any other kind of online privacy tool.

Advantages of Using a Proxy

• Basic Anonymity: Proxies hide your IP address, giving you a layer of anonymity. 
• Bypass Geo-Restrictions: Useful for accessing restricted content that may be blocked based on your location.
• Load Balancing: Proxies can distribute network traffic, making them beneficial for handling high loads, especially in corporate networks.

Drawbacks of Using a Proxy

• Lack of Encryption: Proxies don’t encrypt your data, leaving it exposed to third parties, hackers, or anyone intercepting your traffic.
• Limited Compatibility: Proxies are often only compatible with specific applications or services, not covering all internet traffic.
• Risk of Logs: Many proxy servers keep logs of your browsing history, which can be accessed by third parties.

What Is a VPN?

A VPN creates a secure tunnel between your device and the VPN server, encrypting all your internet traffic. When you access a website through a VPN, your data is sent through this encrypted tunnel to the VPN server, which then forwards it to the destination site. The website sees the VPN server’s IP address, not yours. Here are the types of protocols used at Windscribe VPN: 

The Different Types of VPN Protocols:

1. OpenVPN: Known for its security and speed, OpenVPN is highly configurable and widely used.
2. IKEv2/IPsec: Known for fast reconnection times, IKEv2/IPsec is ideal for mobile users who frequently switch between networks.
3. WireGuard: A newer protocol, WireGuard is lightweight and offers faster connections than many older protocols.
4. Wstunnel: Encapsulates OpenVPN in a WebSocket. Use this only when all other methods fail. May also be handy on restrictive school / office networks and in countries such as China, Russia, UAE, and Iran.
5. Stealth: Encapsulates OpenVPN in a TLS tunnel via Stunnel. Only use this if all other methods fail. May be handy on restrictive school / office networks and in countries such as China, Russia, UAE, and Iran.

Advantages of Using a VPN

• Strong Encryption: VPNs encrypt all your internet traffic, providing an extra layer of security and privacy.
• Bypass Geo-Restrictions and Censorship: VPNs let you access content or services that may be restricted in your region.
• Anonymity and Privacy: With IP masking and encryption, VPNs hide both your IP address and your online activities from ISPs and other third parties.

Drawbacks of Using a VPN

• Potential Speed Reduction: The encryption process can slow down your internet speed, though this impact varies based on the VPN provider and protocol.
• Device Compatibility: Some older devices may not support VPNs or may struggle to run them efficiently.
• Cost: While there are free VPNs, the best ones require a paid subscription to ensure quality, speed, and security.

Key Differences Between a Proxy and a VPN

1. Level of Security

• Proxy: Provides minimal security. Since most proxies don’t encrypt data, they’re not ideal for sensitive tasks like online banking.
• VPN: Provides high-level encryption, making it more suitable for privacy-conscious users and those handling sensitive information.

2. Data Encryption

• Proxy: Typically does not offer data encryption, leaving information vulnerable to interception.
• VPN: Encrypts all data transmitted between your device and the internet, providing a robust layer of protection.

3. Device-Wide vs. Application-Specific

• Proxy: Often limited to individual applications, like a web browser or torrent client.
• VPN: Works across all applications on your device, offering broader protection and convenience.

4. Speed

• Proxy: Typically faster since there’s no encryption involved, but performance may vary based on server quality.
• VPN: May reduce speed slightly due to encryption overhead, although modern VPNs often optimize performance to minimize this impact.

5. Cost

• Proxy: Many proxies are free or low-cost, though premium options exist.
• VPN: High-quality VPNs generally require a subscription, although free options exist with limited features.

When Should You Use a Proxy?

Basically any circumstance where cost is a factor and security is not. Free Proxies are generally effective for the following kind of tasks:

1. Bypassing Regional Restrictions for Basic Browsing

If you only need to access geo-blocked websites and aren’t concerned about security, a proxy can be a quick, low cost, and convenient solution.

2. Handling Low-Sensitivity Tasks

Proxies are suitable for non-sensitive tasks like casual browsing, accessing social media sites, or bypassing network restrictions at school or work.

3. Streaming Content with Minimal Speed Reduction

Since proxies don’t encrypt traffic, they are generally faster, making them ideal for low-security streaming tasks that need high speed but not privacy.

When Should You Use a VPN?

Whenever security is your main concern. A reputable VPN will cost money, but it’s usually worth the price to keep yourself protected online, especially in scenarios like:

1. Securing Public Wi-Fi Connections

Public Wi-Fi networks are highly susceptible to attacks and prying eyes. A VPN encrypts your connection, protecting you from potential data theft. 

2. Bypassing Censorship and Government Restrictions

In countries with restrictive internet policies, VPNs can help users access blocked content while maintaining privacy and anonymity.

3. Protecting Sensitive Information

If you’re handling sensitive data—like personal finance or work-related information—adding a  VPN on top helps ensure your data remains secure and private.

4. Torrenting and P2P Sharing

VPNs are ideal for torrenting as they mask your IP address and encrypt your data, keeping you anonymous and protected from potential legal or privacy issues, especially for those living under repressive regimes. 

Proxy vs. VPN: Which One Should You Choose?

Choosing between a proxy and a VPN depends on your specific needs:

• If you prioritize privacy and security: Go with a VPN. The encryption and IP masking make it a superior choice for users who want peace of mind, especially on public Wi-Fi or in restricted areas. Using a VPN also gives you more control over your connection routing, which may positively affect your connection speed.
• If you need speed for low-risk browsing: A proxy might be sufficient. For accessing geo-restricted content without significant privacy concerns, proxies offer a lightweight and often faster alternative.
• For all-around coverage and flexibility: VPNs cover all your applications and provide a consistent experience across your device, while proxies may only work on specific applications.

Can You Use a Proxy and a VPN at the Same Time?

Yes, it is possible to use both at the same time. However, this generally requires some special configuring and adding another middle layer to your internet connection. Instead, you should consider using a service that offers hybrid options that combine the ease of use of proxies with the security features of VPNs. 

Some examples include Smart DNS services like Control D and VPN proxy services, which aim to offer the best of both worlds by enabling faster connections for geo-blocked content without full encryption. The Windscribe Browser Extension takes things to the next level, offering all the benefits of a Proxy AND a VPN all in one on your browser of choice. If you’re really serious about privacy, Double Hopping will cover your tracks and keep both your browser and non-browser internet connection safe and secure. 

Do I Need a Proxy and a VPN at the Same Time?

Generally speaking, it’s not necessary to use both at the same time. The only scenario where it’s pragmatic to do so is if you’re looking for extra security while using an internet browser specifically. In those cases, double hopping will be your best bet. 

Conclusion

Both proxies and VPNs have their place in the digital privacy tools, and the right choice depends on your specific needs. If you’re looking for basic anonymity and want to bypass location restrictions for non-sensitive tasks, a proxy might be all you need. But if privacy, security, and versatility are a priority, investing in a reputable VPN service like Windscribe is well worth it.

Whether you’re a casual user or a privacy-conscious individual, understanding the strengths and limitations of these tools empowers you to make the best choice for your online experience. With either option, you’re one step closer to taking back control of your data online while navigating an ever-connected world.
