Why scan your domain?
Email authentication records (SPF, DKIM, DMARC) are your domain's first line of defense against impersonation. Without them, attackers can send emails that appear to come from your domain — tricking your customers, partners, and employees.
91% of cyberattacks start with a phishing email. If your domain lacks proper authentication, you're not just vulnerable — you're a weapon. Attackers use unprotected domains to impersonate legitimate businesses and launch targeted phishing campaigns.
Who should scan their domain?
- IT admins — verify your authentication is configured correctly
- Security teams — audit vendor and partner domains before trusting their emails
- Business owners — make sure no one is impersonating your brand
- Sales teams — check prospect domains to understand their security posture
