VPN vs Proxy: What's the Real Difference?
Type “free proxy” into any search engine and you’ll get thousands of results promising a new IP address in seconds. Search for a VPN and you’ll get a similar promise. The two terms get thrown around as if they’re the same thing, but they solve different problems — and mixing them up can leave you with far less protection than you think you have.
What a proxy actually does
A proxy server sits between your device and the website you’re visiting. Your request goes to the proxy first, the proxy forwards it to the destination, and the response comes back the same way. The website sees the proxy’s IP address instead of yours.
That’s it. That’s the whole job.
A proxy does not encrypt your traffic. It typically only routes the traffic of one app or browser you’ve configured to use it — your other apps keep connecting directly. On public Wi-Fi, anyone monitoring the network can still read unencrypted data passing through, because a proxy doesn’t wrap your connection in any protective layer.
What a VPN actually does
A VPN (Virtual Private Network) builds an encrypted tunnel between your device and a remote server, and routes all of your device’s traffic through it — not just one browser tab. Encryption typically uses AES-256, the same cipher standard used by governments to protect classified data. Even if someone intercepts the traffic, they see scrambled noise, not your activity.
A useful way to remember it: a proxy changes your address on the envelope. A VPN puts the whole envelope inside a locked box before it leaves your hands.
Proxy vs VPN: side by side
| Proxy | VPN | |
|---|---|---|
| Encrypts traffic | No (usually) | Yes (AES-256) |
| Coverage | One app/browser | Entire device |
| Speed | Can be faster (no encryption overhead) | Slightly slower, but modern protocols close the gap |
| Typical cost | Often free | Usually paid |
| Privacy policy | Rarely published | Standard for reputable providers |
| Public Wi-Fi safety | Minimal | Strong |
Why free proxies are riskier than they look
Free proxies have to make money somehow, and that “somehow” is often the data passing through their servers. A study of roughly 13,000 public proxy servers found that 79% were either unsafe — no HTTPS support — or actively harmful, injecting HTML or JavaScript into pages users visited, according to security researchers cited by industry outlets. A separate scan of 25,000 open proxies found that only 14% were safe to use at all.
- No encryption means your ISP, network operator, or anyone on the same Wi-Fi can see what you’re sending.
- No audited privacy policy means you often don’t know who’s logging your requests or what they do with them.
- Injected content is a documented risk — some proxies alter the pages you load to insert ads or tracking scripts.
When each one makes sense
- Quick, low-stakes IP swap for one app — a proxy can work if you just need a different regional IP for a single browser task and you’re not handling anything sensitive.
- Everyday browsing on your own devices — a VPN is the better default, since it protects every app without you having to configure each one separately.
- Public Wi-Fi at a cafe, airport, or hotel — a VPN’s encryption is what actually protects you here; a proxy leaves your data exposed on the same network as everyone else.
Public Wi-Fi risk isn’t theoretical — one study tracking unsecured networks captured unencrypted photos, documents, and credentials in plain text within 150 hours of monitoring, and broader survey data puts the share of unsecured-network users who’ve had data compromised at 43%.
What to look for before you pick either one
- Does it encrypt traffic, or just mask an IP? If privacy on public networks matters to you, encryption isn’t optional.
- Does it cover your whole device, or one app? A proxy configured in a browser won’t protect a messaging app running alongside it.
- Is there a published no-logs policy? Free tools rarely publish one — and if there’s no business model, your data may be the product.
- What protocol runs underneath? Modern VPN protocols like AmneziaWG and VLESS-Reality are built for a stable connection without a noticeable speed hit.
RunVPN uses AmneziaWG by default and VLESS-Reality (XTLS-Vision on the Xray engine) as an alternative — both tuned for speed and a stable connection. There’s nothing to configure manually: sign in with Google, email, or Telegram, and the app fetches its setup automatically. The service is no-logs and supports up to 5 devices per account, with Android available now and iOS coming soon.
FAQ
Is a VPN always better than a proxy? For anything involving personal data, passwords, or activity on public Wi-Fi, yes — the encryption gap is the deciding factor. A proxy can still make sense for narrow, low-stakes tasks limited to a single app.
Can I use a VPN and a proxy at the same time? Technically yes, but it adds complexity and latency for little practical benefit once you already have full-device encryption from a VPN.
Do free proxies actually track what I do? Some do. Because they need a revenue model, logging and reselling browsing data is a known pattern among free proxy services — check the research on public proxy safety before trusting one with anything sensitive.
Does a VPN slow down my connection? There’s some overhead from encryption, but modern protocols are designed to keep the difference small enough that most everyday use — browsing, streaming, messaging — feels the same.
