“Anonymous proxy detected” means the website you are visiting has identified your traffic as coming through a proxy, VPN, or anonymizing network and flagged it. It is a server-side anti-fraud check, not a virus or an error on your device. You can usually click through, switch IP, or use a cleaner residential IP.

Why “Anonymous Proxy Detected” Appears and How to Get Past It

The message is triggered by the destination website, not by your computer. Anti-fraud and anti-bot systems (often Cloudflare, MaxMind, or in-house WAF rules) check incoming IPs against databases of known proxy, VPN, and hosting ranges. When your IP matches one of those ranges, the site shows the warning and sometimes asks you to confirm with a “click here” link before it lets you in.

Datacenter proxies trip this filter most often, because their IP ranges are registered to hosting providers and are easy to classify. If you keep hitting the warning on sites you need stable access to, the practical fix is the IP type, not the browser. Rotating to a fresh IP clears a one-off flag; switching to residential or ISP (static residential) proxies removes the root cause, since those IPs are registered to consumer internet providers and are not classified as proxy traffic. Authenticated, non-shared IPs also stay cleaner than public or oversold shared pools.

If you only see the warning occasionally, clicking the link and continuing is safe. If it blocks a workflow, renew the IP from your proxy dashboard or move that target to a residential endpoint.
