To protect data quality and respondent integrity, Norstat applies a multi-layer verification framework across all B2B respondent sources. Verification methods are selected based on channel, audience and risk profile, ensuring that professional relevance and authenticity are confirmed before participation.
The following verification methods form the foundation of our approach:
- Invite-only recruitment
- Professional email verification
- Professional network verification
- Identity and payment validation
- Enhanced identity checks when required
- Continuous monitoring during data collection
All verification methods operate within a strict compliance framework, aligned with ISO 20252, ISO 27001 and GDPR, ensuring secure, responsible and auditable B2B data collection.
