Key facts

Identity and matching scope

Result to inspect

Developer evaluation

Evaluate known repeat visits and different browsers separately. Include cleared storage, privacy settings, browser upgrades, shared devices, missing collection and delayed results. Inspect the returned identifiers and reasons before connecting them to an account action. Vendor page ↗

Current risk context

Risk score and Trusted, Suspicious, Dangerous for visitors, users, devices and IP, with named signals behind the result. Vendor page ↗

Network and device intelligence

A browser snippet collects the visit. Supported client/server SDKs, API and webhooks deliver results for a trusted application integration. Vendor page ↗

Paid plan options

Identity surface

Device ID, Visitor ID and account-associated User HID connect observations with returning visitors and linked account activity. Keep these identifiers distinct from a verified physical person. Vendor page ↗

Anonymity and automation

VPN, proxy, Tor, Apple Private Relay, residential-proxy, anti-detect browser, tampering and automation signals provide current context beside identity. Bot and AI traffic detection separates useful automation from abusive activity. Vendor page ↗
