VPN vs Tor vs proxy: which actually protects your privacy, and from what

“Hide your IP” is the marketing line for all three, and it's the least interesting thing about them. A VPN, Tor, and a proxy defend against different threats and ask you to trust different parties. Pick by what you're actually defending against, not by which has the loudest ad.

Proxy — a relay, not protection

A proxy forwards your traffic through another server, so the destination sees the proxy's IP. That's roughly all it does. A plain HTTP proxy often doesn't encrypt, can see your traffic, and is trivial for your network to observe. Proxies are fine for low-stakes geolocation (appearing to be somewhere else) but are not a privacy tool — you are trusting an unknown operator with unencrypted traffic.

VPN — shifts trust to one provider

A VPN encrypts all your traffic to the provider's server, which then forwards it. This genuinely protects you from your local network and ISP: on public Wi-Fi or a monitored connection, they see encrypted traffic to the VPN and nothing more. The catch: the VPN provider now sees what your ISP used to. You haven't removed trust — you've moved it to the VPN. That's a win if you trust the VPN more than your ISP/network (often true on public Wi-Fi), and meaningless if the provider logs and sells data. A VPN does not make you anonymous to the sites you visit — logins, cookies, and fingerprinting still identify you.

Tor — anonymity by removing single trust

Tor routes your traffic through three volunteer relays, each peeling one layer of encryption, so no single relay knows both who you are and what you're doing. That's real anonymity against network observers, achieved by not having to trust any one party. The cost is speed and convenience: Tor is slow, many sites block or challenge it, and using it carelessly (logging into your real accounts) defeats the point. Tor protects who you are; it can't protect you from yourself.

Match the tool to the threat

• Worried about public Wi-Fi / your ISP / your network seeing your traffic? A reputable, no-log VPN is the right, usable choice.
• Need anonymity — for whistleblowing, research, or evading network-level identification? Tor, used carefully.
• Just need to appear in another country for something low-stakes? A proxy or VPN both work.
• Worried about sites tracking you across visits? None of these fixes that — that's cookies and fingerprinting, a separate problem.

The honest summary

A proxy relays. A VPN moves your trust from the network to a provider. Tor removes single-party trust at the cost of speed. None of them makes you invisible to sites you log into, and none replaces the others. Decide who you're hiding from first; the right tool falls out of that answer.
