The addition of Sentry by CloudResearch will screen respondents before they reach surveys, flagging those identified as inattentive, fraudulent, dishonest and AI-assisted.

Verisoul will run alongside Sentry and will build a composite fraud risk score across device, network and behavioural signals to help uncover fraud rings, cross-continental device farms and other patterns of suspicious respondent behaviour.

Both integrations are housed within Gatekeeper, which connects participants to directly to surveys once they pass validation checks.

Lewis Reeves, chief executive and founder at Walr, said: “This partnership isn’t just a harder line against fraud. It’s a better experience for the respondents who keep this industry moving.

"With the addition of these third-party tools, we’re ensuring genuine participants get the surveys they were meant to take – and researchers get data they can trust.”
