Proxy vs VPN vs Tor: The Real Difference
A proxy, a VPN and Tor all hide your IP address — and that is almost the only thing they have in common. One is a thin disguise for a single app, one is an encrypted tunnel run by one company, and one spreads your trust across three volunteers. Which fits depends on who you are hiding from.
The three tools in one paragraph each
A proxy is a middleman for one app or one site: your browser asks the proxy to fetch a page, and the page sees the proxy's address instead of yours. Most proxies do not encrypt your traffic, and the proxy operator can see everything that passes through. A VPN encrypts all of your device's traffic and sends it through one server run by the VPN provider: websites see the provider's address, your internet provider sees encrypted traffic to the provider, and the provider itself can see your traffic. Tor sends your traffic through three volunteer-run relays so no single relay knows both who you are and where you are going: entry knows you but not your destination, exit knows your destination but not you. Tor is free and slow; a VPN is paid and fast; a proxy is often free and weakest of all.
Side by side
| Proxy | VPN | Tor | |
|---|---|---|---|
| What it covers | One app or site | Whole device | Tor Browser traffic |
| Encrypts your traffic? | Usually no | Yes, to the VPN server | Yes, in three layers |
| Who can see your traffic | The proxy operator, anyone on the network | The VPN provider | No single relay sees the whole picture |
| Hides your IP from websites? | Yes | Yes | Yes |
| Hides browsing from your provider? | No | Yes | Provider sees Tor use, not sites |
| Speed | Fast | Fast | Slow, by design |
| Cost | Often free — and that is the risk | Subscription | Free |
The free proxy warning
This is the part the proxy sellers never explain. A proxy operator sits in the middle of your traffic and, with most proxies, that traffic is unencrypted — so the operator can read it, log it, change it, or inject content into it. Free proxies have been caught doing exactly that: swapping ads into pages, logging logins, and redirecting users to fake pages. The "free" proxy is paid for somehow, and with a proxy the payment is usually your data. Never log in to email, banking or any important account through a free proxy, and never type a password into a page reached through one. If a proxy is your only option, treat it as a way to view a public page — never as a way to be private.
Which fits which threat
The right tool follows the watcher you care about. If you only want one website to see a different IP address and there is nothing sensitive involved, a proxy suffices — though a VPN does the same job better. If your concern is your internet provider, your local network or public Wi-Fi, a VPN is the right tool: it encrypts everything and hides your browsing from the network. If your concern is a website learning your real address, or you need onion services, Tor is the right tool. If your concern is being tracked across sites, none of the three solves it — that is cookies and fingerprinting, covered in our how websites track you guide.
For the deeper comparison, see our VPN vs Tor guide, which maps who sees what under each tool, and our what a VPN hides guide, which lists exactly what a VPN does and does not do. From the Tor side, the Tor vs proxy vs VPN page in Tor Education covers the same three tools with the emphasis on how onion routing differs technically — a different angle from this page, not a duplicate.
What none of the three does
None of them makes you anonymous. A proxy operator can see your traffic. A VPN provider can see your traffic. Tor hides your address but not your behaviour: log in, download a file, or run scripts, and you can still be identified. None of them stops tracking cookies, browser fingerprinting, or phishing. And none of them protects a password you reused after a breach. The tools are about who sees your traffic — the rest of your safety comes from the basics: unique passwords, two-factor authentication, updates, and pausing before you click. See our protecting your identity online guide for the full checklist.
A worked example: one request, three tools
Imagine you open a news site from a hotel Wi-Fi. Through a proxy, your browser asks the proxy to fetch the page: the site sees the proxy's address, but the hotel network can still read the unencrypted parts of the traffic, and the proxy operator can see the page you asked for. Through a VPN, your device first opens an encrypted tunnel to the VPN server: the hotel network sees only scrambled traffic, the site sees the VPN server's address, and the VPN provider sees that you visited the news site. Through Tor Browser, your request passes through three relays: the hotel network sees that you use Tor, the news site sees the exit relay, and no single relay sees both you and the site. Same request, same hotel, three very different pictures of who knows what. The proxy hides the least, the VPN hides the network view, and Tor spreads the knowledge so thinly that no one party holds the whole story — at the cost of speed. Keep this picture in mind whenever anyone tells you one of the three is "the private one". Privacy is not a product; it is a question of who sees what, and each tool answers it differently.
Rule of thumb. Proxy: weakest, one app, usually unencrypted. VPN: one trusted company, whole device, fast. Tor: trust spread across three relays, free, slow. Pick the tool that matches the watcher — and never pay for a proxy's promise with your login.

Frequently asked questions
What is the difference between a proxy and a VPN?
A proxy forwards traffic for one app or one site, usually without encrypting it. A VPN encrypts all of your device’s traffic and sends it through one provider’s server. A proxy hides your IP address from one site; a VPN hides your browsing from your internet provider too.
Is a proxy safer than a VPN?
No — it is weaker. A proxy usually does not encrypt your traffic, so anyone on the network can still read it, and the proxy operator can see and log everything that passes through. A VPN encrypts the traffic between you and the VPN server. Tor spreads trust across three relays and is stronger than either.
Are free proxies safe?
Usually not. A free proxy operator can see, log, modify or inject content into your traffic — including login pages. Free proxies have been caught doing exactly that. Never log in to anything important through a free proxy.
Which is best: proxy, VPN or Tor?
It depends on the threat. A proxy is the weakest and fits only low-stakes jobs like viewing a page. A VPN fits everyday privacy from your provider and local networks. Tor fits hiding your IP address from websites and spreading trust across relays. None makes you anonymous.
What is the difference between this page and the Tor vs proxy vs VPN page?
This page compares the three tools as everyday privacy choices — what each hides, what each costs, and which fits which situation. The Tor Education page covers the same three tools from the Tor side: how onion routing differs technically and when Tor is the right choice. Both link to each other; neither repeats the other.
