What does your business domain reveal?
Enter your company domain to check publicly available email-security and DNS signals. This is a passive lookup—not a vulnerability scan.
Use the main domain only. Example: ncbcyber.com
Checking public DNS records…
Checks currently include DMARC, SPF, mail routing (MX) and certificate-authority authorization (CAA). Results are indicators only and do not prove that an environment is secure.
