Strengths
- Live corroboration reduces dependence on stale IP blocklists and adds evidence that an IP ownership record cannot supply.
- Device identity helps connect activity across IP changes; ready-made account-abuse findings make the review useful beyond proxy classification.
- Self-serve access and 5,000 free identifications let a small team evaluate supported application flows without an enterprise contract.
Limitations
- Coverage follows the supported collection installed in the protected flow. Evaluate the real signup, login or checkout, including missing-result handling.
- Identification quotas and IP-lookup quotas measure different work. Budget the number of protected identifications and the required plan.
Who it fits
Teams protecting signups, logins, trials and checkout that need VPN, datacenter, residential and mobile proxy context alongside device identity and account-level abuse detection.
Use the alternatives by integration model to compare IP lookup APIs, browser-assisted collection, attribution feeds and local databases.
What the score means
The 9.5 out of 10 score is an editorial assessment under the same 34-criterion, six-category framework. The rubric covers anonymizer coverage, evidence and freshness, operating surface, false-positive discipline, verdict depth and access. The published scale runs from 0 to 10.
The award and score are distinct. Read all criteria and relative weights and verify the required signal and integration for your traffic.
How to evaluate it
Run a known legitimate home-user group and authorized proxy sessions through the same registration or login flow. Rotate the exit while keeping controlled account relationships, then inspect signals, identity continuity, risk and account findings.
