Hi! Here at Spur, this is our mission exactly. As another commenter correctly noted, proxy endpoint data - especially those of residential or "callback" proxies like 911 - is highly ephemeral. Our company provides near-real time tracking for many residential & datacenter proxy services, as well as VPNs.

You don't really explain it in your marketing copy, but how do you detect residential proxies?

You say it yourself:

> Residential proxies can be impossible to detect.

The appeal of residential proxies is that the traffic comes from legitimate user networks. So how do you detect malicious usage there?

Moreover, it must be a game of whack-a-mole to keep your lists updated, as these services pop up all the time.

Hi!

Very interesting service, but sadly I cannot sign up for a trial, due to not possessing a US telephone number, which for some reason is required. That said I am a researcher at an Internet measurement and security group. Any chances for a cooperation?

Hey there, thanks for your interest. Email us at support + our domain and we can get you set up.

Your pricing is very unlisted and gated behind a sales team. Would you mind dropping some ballparks for us?

I saw some indication at the bottom of this page: https://spur.us/products/context-api

Why does spur treat MTN mobile service in Nigeria as a proxy? https://www.mtn.ng/

since these proxy services are created by hijacking legitimate users' computers and internet connections, I would imagine any such list would be quickly out of date. Based on their marketing information, at least hundreds of new computers were added to their network each day.

The whole point of these services is to buy proxies that are not on a list.

My first thought is, "Why would it benefit your company, unless you were dealing with payments directly?," and then I read your comment history and it all makes sense now, haha.

Honestly, for assessing risk of individual users, my worry is that the only good option right now is to use tools that require lots of data on the user, like recaptcha v3. You could set up a honeypot that tries to catch as many IP addresses implicated in proxy activity as possible. Maybe that second one would be a good company idea.

I know at least two:
