Security Warnings
Domain Name System; a distributed directory that maps domain names to IP addresses. A, MX, and TXT records serve different purposes.
A valid SSL certificate ensures data encryption, increases user trust, and positively contributes to your Google ranking.
Unnecessary open ports increase your attack surface. Ports like 23 (Telnet), 3306 (MySQL), 3389 (RDP) should not be exposed to the internet.
Critical security configurations like SPF, DKIM, DMARC, and Google site verification are stored in TXT records.
The A–F grade is calculated based on SSL validity, critical/dangerous open ports, and SPF/DMARC presence. A is most secure, F is critically risky.
Shows which services of a system are accessible over the network. Every open port is a potential attack point.
