ShieldLabs identifies anonymous visitors and detects anonymity at any level with up to 99% accuracy, so you can assess traffic quality and prevent abuse and fraud: multi-accounting, bonus abuse and fake signups.

It recognises visitors behind VPNs, proxies, Tor and anti-detect browsers, then returns a risk score from 0 to 100 with the named signals behind it. Your code decides what happens next.

One JavaScript snippet, about five minutes to the first signal, then a API and webhooks. 5,000 free identifications, no credit card. Paid plans are published and flat, self-serve throughout.
