SPF, DKIM and DMARC
Help receiving mail systems determine whether email using a domain follows the sender policies configured by that domain.
Security comparison
Email security protects messages. Corporate identity verification protects representation.
SPF, DKIM, DMARC, secure email gateways and anti-phishing tools are essential. They help protect email infrastructure and message authenticity. CardIQ addresses a different question: is this person, number, WhatsApp contact, email address or domain currently recognized by this company as an authorized communication channel?
What email and domain security does well
Secure email gateways
Inspect messages, links, attachments and sender behavior to reduce phishing, malware and business email compromise risk.
Domain ownership and configuration
DNS and domain security controls establish technical authority over internet domains and mail infrastructure.
These controls are essential and CardIQ does not replace them.
The gap: authorized representation across channels
A scammer can impersonate a company outside corporate email — for example through WhatsApp, a mobile number, a copied executive photo, a lookalike domain or stale employee details. Email authentication alone cannot answer whether that external identity is currently authorized by the organization.
Company-scoped verification
CardIQ lets a visitor select the company first, then check a submitted email, mobile, WhatsApp number, landline or trusted domain against the company’s current authorized records.
Privacy-preserving result
The result confirms organization-level recognition without providing reverse lookup of employee identity or exposing a directory of contact data.
Lifecycle awareness
Verification is limited to active authorized identities, so offboarding can remove a former employee from current verification scope.
Suspected impersonation is reviewed, not automatically declared fraud
A Not Verified result is a reason to stop and verify through another trusted route, not proof that the sender is fraudulent. CardIQ supports privacy-preserving reporting and company-admin review of suspected impersonation signals.
Review before confirmation
Visitor reports begin as suspected cases for review rather than being automatically labeled as confirmed fraud.
Repeated signals
Repeated independent reports can help administrators prioritize suspicious indicators while preserving reporter privacy.
