A proxy reroutes the traffic of one app or one request through another IP address, so a website sees that IP instead of yours. A VPN encrypts all traffic from your device and sends it through one server owned by the VPN company. Tor passes your traffic through several volunteer relays to make you hard to trace, at the cost of being very slow.
In short: a VPN protects a connection, Tor hides an identity, and a proxy server gives an application a different IP and location. Which one you need depends on the job, and for most business data tasks the answer is a proxy.
Proxy vs VPN vs Tor at a glance
| Proxy | VPN | Tor | |
|---|---|---|---|
| What it covers | One app, browser or request | All traffic on the device | The Tor Browser (or apps set to use Tor) |
| Encryption | None of its own; HTTPS encrypts the content | Encrypted tunnel to the VPN server | Layered encryption across relays |
| Speed | Fast, built for many parallel requests | Good, some overhead from encryption | Very slow |
| IP type | Residential, ISP or datacenter | Usually datacenter | Volunteer exit nodes |
| Location control | Country, region, city or ASN per request | Pick a server country or city | Little to none |
| Best for | Data collection, price checks, ad verification, localized testing | Remote work, public Wi-Fi, personal privacy | Anonymous browsing |
How each one works
How a proxy works
A proxy sits between your application and the website. Your browser, scraper or API client sends a request to the proxy, the proxy forwards it from its own IP, and the response comes back the same way. The website only sees the proxy IP.
Only the traffic you point at the proxy goes through it. The rest of your device keeps using your normal connection. That makes a proxy a per-task tool: one scraper can run through Germany while another runs through Brazil, on the same machine.
Proxies come in different IP types. Datacenter proxies use server IPs from hosting companies. Residential proxies use IPs that internet providers assign to real homes, so requests look like ordinary visitors. ISP proxies are registered to consumer internet providers but run on servers. If you are new to the residential type, our guide to what a residential proxy is explains how it works.
With Shifter, for example, you connect to one gateway (p.shifter.io:443) with a username and password. You set the country, region, city or ASN in the username, and choose either a new IP on every request or a sticky session that keeps one IP for a set time, using sid-<id> and ttl-<seconds>. It works over HTTP(S) and SOCKS5, so it fits into most tools without extra software.
How a VPN works
A VPN app creates an encrypted tunnel between your device and a server run by the VPN provider. Everything your device sends goes through that tunnel: the browser, email, chat apps, system updates. Anyone watching your local network, such as the owner of a café Wi-Fi, sees only that you are connected to a VPN server, not what you are doing.
The website you visit sees the VPN server’s IP. That IP is nearly always in a data center and is shared by many VPN users at once, which is why streaming services and strict websites often recognize and block VPN traffic.
How Tor works
Tor, short for The Onion Router, sends your traffic through at least three relays run by volunteers. Each relay removes one layer of encryption and only knows the hop before and after it. The entry relay knows who you are but not where you are going. The exit relay knows the destination but not who you are.
That design gives strong anonymity, but every request travels a long, indirect path. Pages load slowly, exit nodes are public and widely blocked, and you have almost no control over which country your traffic leaves from.
When to use a proxy
Use a proxy when an application needs to reach websites from specific IPs and locations, often many at once. Typical cases:
- Data collection. Web scraping of product listings, reviews, search results or other public data, spread across many IPs so no single address stands out.
- Price checks. Seeing prices, stock and promotions as customers in each market see them, the core of price intelligence.
- Ad verification. Checking that ads appear in the right places and countries, and catching fraud.
- Localized testing. Checking how a website, app or checkout behaves for users in another country or city.
- Many sessions in many locations. Running hundreds of parallel sessions, each with its own IP and location, which a VPN cannot do.
For strict websites, residential IPs work best because they look like normal home users. Teams that need this at scale use residential proxies from a large pool; Shifter’s covers 205M+ IPs in 195+ countries.
A VPN can technically reach the same pages, but it gives you one shared datacenter IP at a time, with no rotation and no fine location control. For anything beyond a few manual checks, that is the wrong tool.
When to use a VPN
Use a VPN when the goal is to protect a device’s connection rather than to collect data:
- Remote work. Employees reach internal systems, files and tools over an encrypted connection from home or while traveling.
- Public Wi-Fi. In hotels, airports and cafés, a VPN stops others on the network from reading your traffic, which matters when you log in to banking or work accounts.
- Personal privacy. A VPN hides your browsing from your internet provider and the local network.
The trade-off is that a VPN covers the whole device, uses some system resources and slows connections slightly because of encryption. It is built for protection, not for reaching websites from many locations.
When to use Tor
Use Tor when anonymity matters more than speed: for example, journalists protecting sources, researchers who must not be linked to what they read, or anyone who needs to browse without the destination knowing who they are.
Tor is a poor fit for business workloads. It is too slow for data collection, many websites block its exit nodes, and you cannot pick an exact location. It also takes some setup to use outside the Tor Browser.
Can you use them together?
Yes, and many companies do. A common setup is a VPN that protects staff connections to internal systems and residential proxies that power the data team’s scrapers and price monitors. The two solve different problems, so one does not replace the other.
You can also chain tools, such as connecting to a proxy while a VPN is on. This adds latency and makes problems harder to debug, so only do it when you have a clear reason.
Some services blur the line, such as residential VPNs that route a device through a home IP. If you are weighing that option, see residential proxies vs residential VPNs.
Proxy or VPN: a checklist for your business
Answer these questions before you choose.
You probably need a VPN if:
- Staff need secure access to internal or confidential work material.
- People on your team often work from hotels, airports or other public networks.
- You want all traffic on a device protected, not only one app.
- Privacy from your local network or internet provider is the main goal.
You probably need a proxy if:
- You need public web data for business decisions, such as prices, listings or search results.
- You need to see websites as users in specific countries or cities see them.
- You run high-volume or automated jobs where speed, uptime and low block rates matter.
- You need many separate sessions, each with its own IP and location.
- Your work covers price comparison, market research, SEO, ad verification, ecommerce or travel data.
If you answered yes in both lists, use both. A VPN for protection and a proxy for access is a normal setup, not overlap.
A proxy is not an anonymity tool
One point often gets lost in proxy vs VPN comparisons. A residential proxy changes the IP address a website sees. It does not make you anonymous, and it does not encrypt your traffic on its own. The encryption that protects the content of your requests comes from HTTPS between your client and the website, which works the same with or without a proxy.
The proxy provider can still see which sites you connect to, and websites can still identify you through logins, cookies and browser fingerprints. If anonymity is the goal, Tor is the closer fit. We explain the limits in detail in why a proxy is not an anonymity tool.
The bottom line
Pick the tool by the job. A VPN protects connections for people. Tor hides identities at the cost of speed. A proxy gives applications the IPs and locations they need, which is why it is the standard choice for data collection, price checks, ad verification and localized testing.
