How DNSAudit.io Improves DNS Audits with WHOIS API

DNSAudit.io & WhoisXML API: Strengthening DNS Security Scans

About

DNSAudit.io is a free and advanced DNS security scanner that pinpoints critical DNS issues, including misconfigurations and security vulnerabilities. It was founded by Esteban Borges, a cybersecurity professional who witnessed first hand how small DNS misconfigurations can lead to bigger problems.

Aside from performing DNS scans and detecting security issues, DNSAudit.io also offers clear, actionable solutions that simplify DNS security management for all users.

Location: U.S.
Industry: Cybersecurity
Products used: WHOIS API

Highlights

Reliable asset discovery and DNS risk detection depend on fast, accurate domain ownership attribution.
Adding up-to-date domain registration context directly into scan results is essential for accurate investigation.
WHOIS API enabled DNSAudit.io to deliver more accurate, enriched, and actionable audit findings

Challenge

Asset Discovery Begins with Accurate Attribution

Among the questions blue teams, red teams, domain owners, and DevOps professionals ask during asset discovery and DNS risk detection is: "Who owns this domain?” Answering this is essential for risk attribution, threat hunting, and understanding infrastructure change.

To deliver the most accurate and thorough findings, DNSAudit.io needed a reliable, fast, and accurate source for enriching their scans with external domain ownership intelligence.

Solution

Integrating Precise Domain Registration Context

DNSAudit.io partnered with WhoisXML API to integrate the WHOIS API directly into the WHOIS analysis section of the DNSAudit.io platform. The integration allows users to see current ownership and registration details alongside security scan results, including the registrar, domain age, WHOIS server, nameservers, expiration date, status codes, and registrant and technical contact details.

Results

Better Attribution and Enhanced Investigation

The partnership between DNSAudit.io and WhoisXML API has improved the platform's ability to provide context and attribution, strengthening security findings, particularly through:

Better accuracy across DNS checks: Rich, accurate data ensures DNS audit findings are authoritative and reliable.
Faster investigations: Users can access domain ownership and infrastructure details instantly during a scan.
Stronger attribution and prioritization: Detailed ownership and registrar data enable clearer risk attribution and more effective mitigation decisions.

Together, these improvements enable DNSAudit.io to deliver more accurate, enriched, and actionable audit findings that help users spot misconfigurations and address them faster.
