FAQs
What survey platforms does Verisoul work with for market research?
What survey platforms does Verisoul work with for market research?
Verisoul works with any survey platform used for market research and insights without adding interview length or additional questions.
Verisoul is survey-platform agnostic and integrates into any online research, sampling, or panel workflow. Customers actively use Verisoul with leading survey platforms including:
Verisoul also integrates with custom, proprietary, and in-house survey systems used for brand tracking, concept testing, ad testing, U&A studies, and longitudinal research.
Because Verisoul operates independently of survey logic and question design, integration does not require survey rewrites or platform-specific customization. Verisoul also operates invisibly without adding any user friction or additional screening questions.
Does Verisoul detect AI agents like ChatGPT in market research surveys?
Yes. Verisoul detects AI agents and automated respondents in market research surveys in real time.
Based on third-party customer testing, Verisoul detects 100% of the latest AI agent respondents, including ChatGPT Operator & Atlas, Google Mariner, and other emerging agent frameworks.
Verisoul detects AI-driven survey fraud using:
- Behavioral analysis: Keystroke, click, scroll, and touch patterns that identify non-human interaction
- Device and network behavior: Detection of remote desktop tools, datacenters, and non-consumer environments
- Automation signatures: Identification of device-level and browser-level automation artifacts
Verisoul also conducts continuous red-teaming, including legitimate former fraudsters on payroll, to stay ahead of rapidly evolving AI-based survey fraud.
Can Verisoul detect mobile proxies and residential proxies in online research?
Yes. Verisoul detects mobile proxies, residential proxies, and VPN-based fraud used in online market research.
Unlike legacy market research fraud tools that rely on static IP blocklists, Verisoul uses active network forensics to analyze live session traffic. This allows Verisoul to detect sophisticated proxy usage even when an IP address has never previously been associated with fraud.
Verisoul analyzes:
- Session-level network routing and behavior
- Middleman and tunneling indicators
- VPN and proxy infrastructure signatures
- Location consistency and validation
This approach significantly reduces false positives in global studies, mobile-first research, and international brand tracking.
How does Verisoul perform device fingerprinting for market research surveys?
How does Verisoul perform device fingerprinting for market research surveys?
Verisoul uses processing-based device fingerprinting designed for modern market research environments.
Traditional survey fraud tools rely on passively collected device attributes or cookies, which are easy to spoof, break across browsers, and degrade over time. Verisoul instead analyzes how a device processes tasks, creating a fingerprint that is resilient to:
- Browser upgrades and configuration changes
- Device setting modifications
- Spoofing and emulation
- Cookie deletion or blocking
Verisoul also applies probabilistic identity resolution, providing linkage strength rather than fragile yes/no matches. This enables high-precision, high-recall duplicate detection across surveys, panels, and waves.
How does Verisoul handle IP matching in market research studies?
How does Verisoul handle IP matching in market research studies?
Verisoul uses contextual IP analysis rather than simplistic IP duplicate rules.
Legacy market research fraud tools often flag shared IP addresses as automatic duplicates. This approach produces high false-positive rates, especially in B2B, healthcare, academic, and enterprise research.
Verisoul analyzes the breadth and rarity of each IP address and classifies IPs as:
- Rare IPs: Residential home networks
- Broad IPs: Mobile carriers, hospitals, universities, businesses, and corporate networks
Matching confidence is dynamically adjusted based on IP context, ensuring accurate duplicate detection without penalizing legitimate respondents.
Can Verisoul screen out bad respondents before they enter a survey?
Can Verisoul screen out bad respondents before they enter a survey?
Yes. Verisoul screens out bots, duplicates, and fraudsters in real time before they enter a survey or panel.
Verisoul returns real-time fraud scores during respondent entry, allowing researchers to remove low-quality traffic before survey exposure, incentives, or client delivery.
This helps market research teams:
- Block AI agents and bots
- Prevent duplicate respondents
- Stop professional survey fraudsters
- Protect brand tracking and longitudinal data integrity
Can Verisoul detect mobile and residential proxies and location spoofing in market research studies?
Can Verisoul detect mobile and residential proxies and location spoofing in market research studies?
Yes. Verisoul detects mobile proxies, residential proxies, and location spoofing commonly used to bypass market research panels and surveys.
Unlike legacy research fraud tools that rely on static IP lists, Verisoul uses active network forensics and session analysis to identify proxy usage and false location claims in real time.
Detection techniques include:
- Deep packet inspection–style traffic analysis to flag encrypted packet patterns associated with proxy tunneling and relay infrastructure
- Middleman detection, identifying intermediary devices or services intercepting or forwarding traffic between the respondent and the survey platform
- Location triangulation, where Verisoul correlates network routing, device behavior, and session characteristics to infer a respondent’s true location even when proxies are used
- Device and environment consistency checks, including language, fonts, keyboard layout, time zone, and OS configuration, which often conflict with claimed geography
This allows research teams to stop professional survey fraudsters, proxy-based international spoofing, and paid response farms without increasing false positives in global studies.
