VPN vs Proxy vs Tor
Three tools people lump together — what each one actually does, and when to reach for which.
A VPN encrypts all of your device's traffic and routes it through one provider. A proxy forwards traffic for a single application or destination, often without encryption. Tor anonymizes traffic by relaying it through three volunteer-run nodes — slow but uniquely resistant to network observation.
VPNs, proxies and Tor all change how your traffic reaches the public internet, but the guarantees are very different. Use this table as a quick reference; the rows are ordered from 'most often confused' down to 'most often misused.'
| VPN | Proxy (HTTP/SOCKS) | Tor | |
|---|---|---|---|
| Encrypts your traffic | Yes | Usually no | Yes (layered) |
| Hides your IP from destination sites | Yes | Yes | Yes |
| Hides your destinations from your ISP | Yes | Partial | Yes |
| Provider knows what you do | Yes (one provider) | Yes (proxy operator) | No single party knows full path |
| Speed | Fast | Fast | Slow |
| Covers all apps on your device | Yes | No (per-app) | With Tor Browser; system-wide is advanced |
| Resistant to network-level surveillance | Partial — provider sees all | No | Yes |
| Cost | Paid (recommended) | Free or paid | Free |
| Best use | Privacy on untrusted Wi-Fi; bypassing censorship; isolating your IP | Routing a single app through a different IP (scraping, geo-test, dev work) | Maximum anonymity for low-throughput tasks; censorship circumvention |
| Worst misuse | Trusting any 'free' VPN to keep no logs | Sending login credentials over an unencrypted HTTP proxy | Doing high-bandwidth or identifying activities (logging into your real accounts) over Tor |
Frequently asked questions
Can I run Tor over a VPN?
You can, but it changes the threat model rather than 'doubling up' on protection. The Tor Project has detailed guidance on the trade-offs of VPN-then-Tor and Tor-then-VPN.
Are paid proxies more private than free ones?
Paid generally has clearer accountability and capacity, but a paid proxy that doesn't encrypt traffic still doesn't hide content from on-path observers.
Which should I pick for travel?
A reputable paid VPN is the simplest answer. Tor is appropriate for specific high-risk scenarios but is overkill for normal browsing.
