VPNs, proxies and Tor all do something that sounds similar: they send your internet traffic through another computer so that websites see a different IP address. That is where the similarity ends. They differ in what they encrypt, who they protect you from, how fast they are and how much trust they require.
Choosing the wrong tool can leave you with a false sense of privacy, or with a connection far slower than it needs to be. This guide explains how each one works, compares them side by side, and matches them to real-world situations so you can pick the right tool, or the right combination, for what you actually want to achieve.
Key takeaways
- A proxy relays traffic from one application and usually does not encrypt it. It is fast and flexible, but not a privacy tool on its own.
- A VPN encrypts all traffic from your device to a VPN server. It protects you on local networks and from your ISP, but you must trust the VPN provider.
- Tor routes traffic through three volunteer-run relays with layered encryption, so no single relay knows both who you are and where you are going. It offers the strongest anonymity but is much slower.
- No tool makes you anonymous if you log in to accounts, allow tracking or leak identifying information yourself.
- Pick based on your threat model: who you want to hide from, and what they are capable of.
How a proxy server works
A proxy is an intermediary server that makes requests on your behalf. Your application connects to the proxy, the proxy connects to the destination, and the destination sees the proxy's IP address instead of yours. Proxies are configured per application, or sometimes system-wide through the operating system's proxy settings, and only traffic from applications that honour those settings goes through them.
HTTP and HTTPS proxies
An HTTP proxy understands web traffic. For plain HTTP requests it can read, cache and even modify content, which is why companies and schools use them for filtering. For HTTPS sites, the browser uses the CONNECT method to open a tunnel through the proxy, so the proxy sees the destination hostname and port but not the encrypted content. The connection between you and the proxy itself is usually unencrypted unless the proxy specifically supports TLS on that link.
SOCKS5 proxies
SOCKS5 works at a lower level and relays arbitrary TCP connections (and UDP, where supported), so it can carry traffic for browsers, torrent clients, games and custom tools. It supports username and password authentication but does not encrypt the data it carries. Any encryption comes from the application protocol, such as HTTPS.
Where proxies shine
Proxies are lightweight and add very little overhead, which makes them ideal for tasks where you need a different IP address for one application rather than encryption for everything: web scraping, testing how a site looks from another country, managing multiple accounts, or routing a single tool through a fixed IP. PD-Proxy's Premium Proxies are dedicated HTTP(S) and SOCKS5 proxies built for exactly these jobs.
Be careful with free public proxies. An open proxy of unknown origin sees all of your unencrypted traffic and can inject content into it. Never send passwords through a proxy you cannot trust, and never assume a proxy encrypts anything.
How a VPN works
A VPN (virtual private network) creates an encrypted tunnel between your device and a VPN server. The VPN client installs a virtual network interface, and the operating system routes all of your traffic, from every application, through that interface. The client encrypts each packet, sends it to the VPN server, which decrypts it and forwards it to the internet. Replies take the same path back.
From the perspective of your Wi-Fi network or internet provider, you have a single encrypted connection to one server. They cannot see which sites you visit, what you do on them, or which apps you use. Websites see the VPN server's IP address instead of yours. You can check this yourself on our What is my IP page before and after connecting.
The trust question
A VPN moves trust rather than eliminating it. Your ISP can no longer see your activity, but the VPN server handles your traffic instead. This is why the provider's logging policy, ownership and track record matter. PD-Proxy does not log browsing history, traffic content, DNS queries or the IP addresses of sites you visit; the details are set out in our privacy policy.
Protocols and speed
Modern VPN protocols such as WireGuard, OpenVPN and IKEv2/IPsec use strong, well-studied encryption, and on a nearby server the speed penalty is usually small. We cover the differences in depth in VPN protocols explained.
How Tor works
Tor (originally "The Onion Router") is a free, open-source network run by thousands of volunteer relays. The most common way to use it is the Tor Browser, a hardened version of Firefox that routes its traffic through the Tor network.
Onion routing in three hops
When you open a connection, Tor Browser builds a circuit through three relays: a guard (entry) relay, a middle relay and an exit relay. It wraps your data in three layers of encryption, one for each relay. Each relay removes one layer, learning only the previous hop and the next hop:
- The guard knows your IP address but not where your traffic is going.
- The middle relay knows neither you nor the destination.
- The exit relay knows the destination but not who you are.
Because no single relay knows both ends, you do not have to trust any one operator the way you trust a VPN provider. That is Tor's core advantage.
Tor's limitations
- Speed. Three hops through volunteer relays around the world add noticeable latency and limit bandwidth. Streaming, large downloads and gaming are impractical.
- Exit traffic is not encrypted by Tor. Between the exit relay and the website, only the site's own encryption (HTTPS) protects you. A malicious exit could read or alter plain HTTP traffic.
- Blocking and friction. The list of Tor relays is public, so many websites show extra CAPTCHAs or block Tor exits, and some networks block access to Tor entirely (bridges and pluggable transports can help).
- Browser-only by default. Tor Browser protects only what you do inside it. Other apps on your computer continue to use your normal connection.
- Visibility. Your ISP cannot see what you do over Tor, but it can usually see that you are connecting to the Tor network unless you use a bridge.
Side-by-side comparison
The table below summarises how the three tools compare on the points that matter most in everyday use.
| Feature | Proxy | VPN | Tor |
|---|---|---|---|
| Traffic covered | Only apps configured to use it | All device traffic | Tor Browser (or apps configured for Tor) |
| Encryption | Usually none on its own | Strong encryption from device to VPN server | Layered encryption inside the Tor network; none from exit to site |
| Hides your IP from websites | Yes | Yes | Yes |
| Hides activity from local Wi-Fi and ISP | No (except the content of HTTPS sites) | Yes | Yes (Tor use itself may be visible) |
| Who you must trust | Proxy operator | VPN provider | Distributed; no single relay sees both ends |
| Speed | Fast | Fast to very fast | Slow |
| Streaming and gaming | Possible, app-dependent | Well suited | Not practical |
| Anonymity level | Low | Moderate (privacy from networks, not from the provider) | High, if used carefully |
| Ease of use | Manual per-app setup | One-tap app | Dedicated browser |
| Cost | Free to paid | Free tiers and paid plans | Free |
Think in threat models
"Which is best?" has no universal answer. A threat model is a simple way of asking: what am I protecting, and from whom? The right tool depends on the adversary.
The person on the same Wi-Fi network
Someone sniffing traffic in a café, or a rogue hotspot, can see unencrypted data and the domains you visit. A proxy does little here, because the link to the proxy is usually unencrypted. A VPN is the natural fit: it encrypts everything leaving your device. Tor also protects you but only for the browser. See our public Wi-Fi security guide for the full picture.
Your internet provider or network administrator
ISPs can see the domains you connect to and may log them. A VPN hides your activity from them and replaces it with a single encrypted connection. Tor achieves the same but at a cost in speed.
Websites, advertisers and trackers
All three tools hide your IP address, but trackers rarely rely on IP alone. Cookies, logged-in accounts and browser fingerprinting identify you just as well. Tor Browser is designed to make users look alike and resist fingerprinting; a VPN or proxy on its own does not. Pair any of them with a privacy-respecting browser, tracker blocking and sensible cookie settings.
A well-resourced adversary targeting you personally
If you are a journalist, activist or source whose safety depends on not being identified, Tor (or a dedicated privacy operating system built around it) is the appropriate tool, used with strict operational discipline. A commercial VPN is not designed for this threat model, because the provider is a single point that could be compelled or compromised.
Which should you use? Recommendations by use case
Choose a VPN
For everyday privacy, public Wi-Fi, travel, streaming, gaming and protecting every app on your phone or laptop at once.
Choose a proxy
For a specific application that needs a different or fixed IP: scraping, ad verification, multi-account management or geo-testing.
Choose Tor
When anonymity from the sites you visit and from any single operator matters more than speed, such as sensitive research or whistleblowing.
- Working from cafés, hotels or airports: VPN, ideally with auto-connect and a kill switch.
- Keeping browsing private from your ISP: VPN for daily use; Tor for occasional sensitive browsing.
- Watching your home streaming services while abroad: VPN with optimised servers, such as our streaming and gaming servers. Respect each service's terms.
- Online gaming with lower exposure to DDoS attacks: VPN on a nearby low-latency server.
- Automation, scraping or account management: dedicated SOCKS5 or HTTP(S) proxies.
- Remote team access to company resources: a business VPN such as PD-Proxy Business VPN with dedicated IPs.
- High-risk anonymity needs: Tor Browser, kept updated, with no personal logins.
Can you combine them?
Yes, and sometimes it makes sense, but more layers are not automatically better.
VPN, then Tor ("Tor over VPN")
You connect to your VPN first, then open Tor Browser. Your ISP sees only VPN traffic and does not learn that you use Tor, and the Tor guard relay sees the VPN server's IP instead of yours. The downside is that the VPN provider knows you use Tor (though not what you do inside it). This is the simpler and more common combination, and it is useful on networks that block or flag Tor.
Tor, then VPN ("VPN over Tor")
Traffic goes through Tor first and then exits through a VPN. This can get past websites that block Tor exits, but it is complicated to set up correctly, most VPN apps do not support it, and it ties your Tor activity to a VPN account, which can reduce anonymity. Most people should avoid it.
VPN plus proxy
A common and practical setup: the VPN encrypts everything from your device, while a specific tool uses a proxy to appear from a particular IP address. The proxy's outgoing traffic is then protected on your local network by the VPN tunnel.
Rule of thumb: add a layer only when it defends against a specific threat you have identified. Every extra hop costs speed and adds another party you must configure correctly.
Common myths
"A VPN makes me completely anonymous."
A VPN hides your IP address and encrypts your traffic from local networks and your ISP. If you log in to your accounts, accept tracking cookies or share personal details, websites still know exactly who you are.
"A proxy is just a cheaper VPN."
They solve different problems. Most proxies do not encrypt anything and cover only the applications you configure. They are excellent tools for IP routing, not substitutes for a VPN's encryption.
"Tor is only for criminals."
Tor is used by journalists, researchers, human-rights organisations, people living under censorship and ordinary users who value privacy. Like any tool, it can be misused, but privacy itself is legitimate.
"HTTPS makes a VPN unnecessary."
HTTPS protects the content of individual website connections. It does not hide the domains you visit from your network, protect traffic from apps that skip encryption, or change your IP address.
"More encryption layers always mean more security."
Stacking tools can add complexity and new mistakes without addressing your real risk. A well-configured single tool beats a poorly configured chain.
Frequently asked questions
Is a VPN or a proxy better for privacy?
For general privacy, a VPN. It encrypts all traffic from your device, whereas a typical proxy encrypts nothing and covers only the applications you configure. Proxies are better when you need a specific IP address for one tool.
Can I use Tor and a VPN at the same time?
Yes. Connecting to the VPN first and then using Tor Browser hides your Tor usage from your ISP and is easy to set up. Expect speeds to be limited by Tor, not by the VPN.
Is using Tor legal?
In most countries, yes. A few restrict or block it, and what you do over Tor is still subject to the law. Check local rules if you are travelling.
Why are some websites blocked when I use Tor?
Tor exit relays are publicly listed, and some sites block or challenge them because of abuse from a minority of users. Trying a new circuit sometimes helps; otherwise, a VPN is less likely to be blocked for everyday browsing.
Does a SOCKS5 proxy encrypt my traffic?
No. SOCKS5 relays connections and can require authentication, but it does not add encryption. Use HTTPS-based services through it, or run the proxy inside a VPN tunnel if you need the local link encrypted.
Conclusion
Proxies, VPNs and Tor are complementary tools, not competitors. A proxy is a fast, precise way to route one application through another IP. A VPN is the everyday workhorse that encrypts everything your device sends and keeps your activity away from local networks and your ISP. Tor is the specialist tool for strong anonymity when speed is secondary. Start with your threat model, pick the simplest tool that addresses it, and remember that your own habits matter as much as any technology.
