Panelist risk scoring
Combine real-time and identity signals to catch panelist fraud
Verisoul uses active forensics to analyze thousands of network, device, behavior, and identity signals about every panelist in real time.
Explore the signals behind the score
Behavior signals
Separate human behavior from automation
Verisoul models mouse, click, keyboard, touch, and clipboard behavior to separate real people from automation, catching everything from simple scripts through to AI agents.
- Catches scripted survey completion and AI agents
- Flags copy-paste behavior
- Runs invisibly, with no friction for real panelists
Device signals
Expose fake devices and emulators
Verisoul runs active lie-detection tests on the device, probing emojis, fonts, and processing capabilities in under 100ms, to expose emulators, virtual machines, browser automation, and fingerprint tampering.
- Detects Android and iOS emulators and virtual machines
- Catches anti-detect browsers like OctoBrowser and tampered fingerprints
- Recognizes returning devices across browsers, incognito, and privacy modes
Network signals
Catch proxy, VPN, and location spoofing
Verisoul runs active network fingerprinting tests against the live connection, catching rotating mobile, residential, and other sophisticated proxies. Most vendors rely on IP reputation lists, which go stale and flag real users.
- Pierce proxies and VPNs to reveal the true country of users
- Device and network mismatch flags hidden proxy use
- Active testing finds proxies on first sight and keeps false positives low
Email signals
Check email authenticity at registration
During registration, Verisoul checks email age, live deliverability, disposable and relay domains, and machine-generated usernames, then confirms real online presence across 27 global platforms and breach data from 3+ independent sources.
- Rejects disposable, relay, and machine-generated addresses
- Non-deliverable addresses are 18x more likely to be fraud
- Runs at signup, so fake accounts never reach a study
Duplicate account identification
Link signals across sessions to identify duplicate accounts
Accounts run by professional respondents get matched on browser, device, network, and email. Every match is scored as a probability rather than a hard device ID, which means fewer false positives on real panelists.
- Catches repeat panelists across studies
- Works across browsers, devices, and incognito
- Every match carries a confidence level
Every panelist gets an overall risk score and a decision of real, suspicious, or fake, built from behavior, device, network, and email signals.
