"Proxy" and "VPN" get used interchangeably because both can present a different IP address to the website you're visiting. Under the hood they solve different problems: a proxy is a relay for one app at a time, usually without encrypting your traffic; a VPN is a system-wide encrypted tunnel covering everything on your device (privateproxyguide; joshwp). If your goal is privacy + security across all your apps, pick a VPN. If you only need to route a single app or an automated task through a different IP, a proxy can be appropriate.

What a proxy actually does

A proxy server sits between your app and the internet: your request goes to the proxy, the proxy forwards it, and the destination sees the proxy's IP instead of yours. Proxies work at the application layer — you configure one per app or per protocol — and come in several types (privateproxyguide):

The hard limits: proxies don't encrypt your traffic, so your ISP can still see what you're doing; they don't stop DNS leaks (your DNS requests may still go to your ISP's servers, revealing which sites you visit); and websites can still track you through cookies and browser fingerprinting. The proxy operator itself can see all your unencrypted traffic — and most free proxies log that data and sell it (eneba; Gizmodo).

What a VPN actually does

A VPN creates an encrypted tunnel between your device and the VPN server — typically AES-256, the same cipher governments use for classified material. Your device encrypts all outgoing traffic before it leaves, the VPN server decrypts it and forwards it, and the destination sees the server's IP. This happens at the system level: browser, games, streaming apps, email, torrent clients, background services — everything routes through the tunnel automatically, nothing leaks through your regular connection (eneba). Modern protocols (WireGuard, NordLynx, Lightway) shrink the encryption overhead to a few percent of your speed (Gizmodo).

VPN vs proxy: side by side

ProxyVPN
EncryptionUsually none — traffic travels in the open (SOCKS5 doesn't encrypt either)Full-tunnel AES-256 / ChaCha20 encryption
ScopeOne configured app at a timeWhole device, all apps, automatically
PrivacyHides your IP from the destination — but your ISP and the proxy operator see everythingHides activity from your ISP and the destination; only the VPN provider could theoretically log (audited no-logs policies address this)
SpeedOften faster — skipping encryption is cheaperA few percent overhead with modern protocols
DNS leaksNo built-in protection — leaks are commonDNS leak protection is standard in reputable clients (verify with our VPN leak test)
Best forQuick IP changes, web scraping, ad verification, app-specific routingBanking, public Wi-Fi, torrenting, gaming, remote work

FAQ

Is a VPN a proxy?

Sort of — a VPN does include IP masking like a proxy, but adds whole-device encryption, which a proxy generally doesn't. Treating them as the same thing is how people end up unprotected on public Wi-Fi with only a proxy running (privateproxyguide).

Is a proxy faster than a VPN?

Usually, yes — proxies skip the encryption work that costs VPNs a few percent of speed. It's a trade you shouldn't want for anything sensitive (Gizmodo).

Can a proxy leak my IP?

Easily. DNS leaks are common with proxies, WebRTC can expose your real IP in the browser regardless, and transparent proxies may pass your real IP in headers. Run our VPN leak test and learn about WebRTC leaks.

Do I need both?

Organizations sometimes use both for different jobs — proxies for managed web filtering, VPNs for secure remote access. For personal use, a reputable VPN covers everything a proxy would do for you, encrypted (joshwp).
