Automated External Attack Surface Assessment and Domain Report

Automated External Attack Surface Assessment and Domain Report

Automated External Attack Surface Assessment and Domain Report

This automation performs a scheduled external attack surface assessment for a domain by enumerating subdomains, checking DNS and email security configuration, and examining publicly exposed infrastructure. It consolidates the findings into a structured markdown report with risk analysis, a TL;DR, and follow-up actions.

Trigger

A scheduled execution for a configured target domain initiates subdomain discovery and the associated DNS, mail-security, and public-exposure checks.

Outcome

A consolidated markdown domain assessment is produced with DNS, email-security, subdomain, exposed-service, risk, summary, and follow-up findings.

Trigger

A scheduled execution for a configured target domain initiates subdomain discovery and the associated DNS, mail-security, and public-exposure checks.

Outcome

A consolidated markdown domain assessment is produced with DNS, email-security, subdomain, exposed-service, risk, summary, and follow-up findings.

Before

Security teams had to run DNS lookups, subdomain searches, mail-security checks, and public asset queries across separate tools. They then copied results between tools, interpreted the findings, classified discovered hosts, and assembled the assessment report manually.

How it works

  1. The scheduled flow discovers subdomains, nameservers, MX records, and related DNS data for the target domain.
  2. It validates DNS behavior, checks mail-security configuration, examines exposed services, and applies rules to classify assets and assign confidence.
  3. It merges the assessed sections into a markdown report containing a TL;DR summary and follow-up actions.

Workflow details

  • Scope discovery: The workflow starts with a configured target domain, enumerates its subdomains, identifies nameservers and MX records, and prepares the discovered hosts for further assessment.
  • DNS security assessment: For each nameserver, it resolves the server address, performs lame delegation checks, attempts a zone transfer, tests recursive behavior, and reviews exposed services and ports. DNS records are also evaluated for A, AAAA, CNAME, TXT, SPF, and related relationships.
  • Email security assessment: The workflow checks MX records and runs SMTP, SPF, and DMARC assessments. Results are grouped into passed, failed, warning, timeout, and informational findings so the report can describe the security posture of mail-related infrastructure.
  • Public exposure and role analysis: Discovered hosts and resolved IP addresses are checked for publicly visible services, software details, open ports, and reported vulnerabilities. Automated reasoning applies a defined ruleset to classify host roles, add supporting evidence, and assign confidence levels.
  • Report generation: Findings are cross-checked in report sections, merged, and converted into a consolidated markdown assessment covering DNS, mail security, subdomains, and exposed infrastructure, followed by a summary and recommended follow-up actions.

What changed

The complete assessment is generated on schedule from one target-domain input. DNS, mail, subdomain, and public-exposure checks are performed consistently, findings are classified and cross-checked automatically, and the final report is assembled without a manual reporting handoff.

Work removed

Manually running repeated DNS, subdomain, MX, SMTP, SPF, and DMARC checks; resolving nameservers and testing zone transfers or recursion; searching discovered IPs for exposed services and vulnerabilities; classifying hosts; copying findings between tools; and writing the assessment report and follow-up summary.

Expected outcome

Approximately 45–90 minutes of recurring assessment work can be removed per domain and assessment cycle, with consistent coverage of the configured DNS, mail-security, subdomain, and public-exposure checks.
