Both a VPN and a proxy hide your real IP address from websites you visit. But that is where the similarities end. The differences in how they work make one dramatically better for privacy than the other in almost every situation.
What Is a Proxy?
A proxy server is an intermediary that forwards your web requests. Your browser sends requests to the proxy, and the proxy forwards them to the destination — so the destination sees the proxy's IP, not yours.
Most proxies are single-purpose: an HTTP proxy only handles web traffic. They are fast and easy to set up, but they have critical limitations.
What Is a VPN?
A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. All traffic from your device — not just your browser, but every app — passes through this tunnel. The VPN server's IP appears as your IP to the outside world.
Key Differences
- Encryption — VPNs encrypt all traffic end-to-end. Most proxies offer no encryption. On public Wi-Fi, a proxy user is vulnerable; a VPN user is not.
- Scope — A proxy covers only one browser or app. A VPN covers your entire device.
- Speed — Proxies are generally faster because there is no encryption overhead.
- Logging — Proxy providers frequently log traffic. Reputable VPN providers have audited no-logs policies.
- DNS leaks — Proxies do not protect your DNS queries. Your ISP still sees every domain you visit. VPNs route DNS through the encrypted tunnel.
When to Use a Proxy
Use a proxy when you need to quickly bypass a geo-restriction for a single browser tab and you are not dealing with sensitive data.
When to Use a VPN
Use a VPN for everything else: private browsing, torrenting, public Wi-Fi, accessing sensitive accounts, or any situation where privacy and security matter.
Test Your VPN or Proxy
Whether you use a VPN or proxy, test it using Anonymiz WebRTC Leak Test and DNS Leak Test to verify your real IP is actually hidden.
