What drives the score.
The 8.3 score recognizes visitor identity, SDK reach and Smart Signals. This ranking puts more weight on a ready account-level verdict than on a developer building block. These six factors show the documented evidence and the questions behind the full 38-criterion rubric.
| Detection coverage 30 percent of rubric | A browser agent and API identify returning visitors; Smart Signals include device, browser and network-related risk information. |
|---|---|
| False-positive discipline 18 percent of rubric | Persistent identity can add context beyond a shared IP; test both false merges and missed returning visitors. |
| Integration 16 percent of rubric | Browser agent and API |
| Freshness 14 percent of rubric | Signals are evaluated with each identification. |
| Verdict depth 12 percent of rubric | Visitor ID, Smart Signals and a Suspect Score; VPN and proxy signals are part of Smart Signals, so Fingerprint is not purely device-only. |
| Pricing and access 8 percent of rubric | Up to 1,000 identification calls per month; web Smart Signals on Pro Plus; 99 US dollars per month for 20,000 calls |
