People sometimes buy proxies expecting anonymity: that no website, no provider and no authority will ever be able to tell who sent a request. That is not what a proxy does, and a provider that promises it is not being straight with you. We would rather say so plainly.
A residential proxy does one specific job well: it changes the IP address and location a website sees, so your request arrives from a home connection in the country or city you chose. That is enough for collecting public data as local visitors see it, testing how sites behave in other markets and spreading load. It is not the same as being anonymous, and the difference matters both for what you can rely on and for what you are responsible for.
What a proxy changes
When you send a request through a proxy, the website sees the proxy’s exit address instead of yours. In practice that means the site:
- sees an IP address in the country, city or network you selected;
- applies whatever it does by location, such as currency, language, content and prices, based on that address;
- cannot see your own IP address from the request itself.
That is the whole of it. Everything else about the request, and about you, travels through the proxy unchanged or is visible somewhere else.
What a proxy does not hide
Your accounts. If you log in, the site knows who you are, whatever the IP. Cookies, session tokens and account history identify you far more precisely than any address.
Your browser and client. Sites recognise clients by how they connect and behave: the TLS handshake, HTTP headers, browser features, screen size, fonts and timing. A proxy does not change any of these. Our guide to TLS and HTTP/2 fingerprinting explains how much a client reveals before a single page loads.
Inconsistencies. A browser in one timezone and language using an exit in another stands out. Our guide to matching proxy geo, timezone and locale covers what has to agree for a session to look consistent, which is a question of consistency, not anonymity.
Leaks outside the proxy. Depending on your setup, DNS lookups or browser features such as WebRTC can bypass the proxy and reveal your own network. Configure clients so that name resolution happens through the proxy and test the setup, rather than assuming.
What you send. Anything you type into a form, upload or include in a request goes to the site as you sent it.
What the proxy provider can see
Every proxy provider sits between you and the website, so it is worth being clear about what that position allows.
- The provider knows who its customer is. You have an account, a payment method and credentials. Traffic through the proxy is tied to that account.
- For HTTPS sites, the provider sees which host you connect to, when and how much data passes, but not the encrypted content of the pages.
- For plain HTTP, the content is not encrypted, so it passes through the provider in the clear. Use HTTPS wherever you can.
- Providers keep records needed to run the service, bill it and prevent abuse. What exactly is kept, and for how long, should be in the provider’s privacy policy. Read it; ours is linked in the footer of every page.
What we cannot promise
We cannot promise that your activity can never be linked to you. Like any legitimate company, a proxy provider responds to valid legal requests under the law that applies to it, acts on credible abuse reports, and suspends accounts that break its terms.
We also do not want customers who need that promise. Proxy networks exist to make legitimate work possible: market research, price monitoring, ad verification, testing, collecting public data. They are not a shield for fraud, account takeover, harassment or other harm, and acceptable use policies, ours included, prohibit those uses. A provider that markets “complete anonymity” or “no logs, no questions” is either describing a service that cannot exist or inviting the customers that make residential networks harder for everyone else to use.
That responsibility runs both ways. Residential addresses belong to real people’s connections, and a provider owes them protection from abuse of their address. Our explainer on how providers ethically source residential IPs covers what that means in practice.
When you actually need anonymity
Some people genuinely need strong anonymity: journalists protecting sources, activists under hostile governments, people at risk from abusers. A commercial proxy is the wrong tool for them. Tools built specifically for anonymity, used with careful operational security, are designed for that threat model in a way a commercial proxy network is not. If your safety depends on not being identified, seek out organisations that specialise in digital security for people in your situation.
What a proxy is good for
None of this makes proxies less useful. They are the right tool when the question is “what does this site show to a visitor from there?”, or when traffic needs to be spread across many addresses to stay within what sites tolerate. Used for that, honestly and within the law, they work well. Our guides to whether web scraping is legal and web scraping best practices cover collecting data in a way that does not need hiding.
FAQ
Does a proxy make me anonymous?
No. A proxy changes the IP address a website sees. Your accounts, cookies, browser fingerprint and the information you send can still identify you, and the proxy provider knows who its customer is.
Can a proxy provider see what I do?
For HTTPS sites, a provider can see which hosts you connect to, when and how much data is transferred, but not the encrypted page content. For plain HTTP, the content passes through unencrypted. What a provider records and for how long should be set out in its privacy policy.
Will a proxy provider share information with authorities?
Legitimate providers respond to valid legal requests under the law that applies to them, as any company does. No legitimate provider can promise otherwise.
What are proxies actually for?
Seeing websites as visitors in another location see them, collecting public data at scale, ad verification, price monitoring, testing, and spreading requests across many addresses. They are tools for legitimate work, not for hiding identity.
The bottom line
A proxy changes where your request appears to come from. It does not change who you are, what you send or what your provider knows about its customers. Use proxies for what they do well, collecting and testing the web as local visitors see it, read your provider’s privacy policy and terms, and treat any promise of complete anonymity as a reason to look elsewhere.
