External Vulnerability Scanning

Continuous or on-demand scanning of external-facing assets to identify exposure from a threat actor's perspective.

What It Is

External vulnerability scanning identifies security weaknesses in your internet-facing infrastructure before attackers find them. We scan your public IP ranges, domains, and cloud assets to detect misconfigurations, unpatched software, exposed services, and other vulnerabilities visible from the outside.

Unlike a one-time pentest, external scanning can be scheduled continuously to maintain ongoing visibility into your attack surface as it changes. This is essential for organizations managing dynamic cloud environments or frequent deployments.

What We Cover

  • Public IP range scanning and enumeration
  • DNS and subdomain reconnaissance
  • SSL/TLS configuration assessment
  • Open port and service identification
  • Known vulnerability detection (CVE matching)
  • Cloud asset discovery (AWS, Azure, GCP)
  • Web server and CMS vulnerability scanning
  • Email security assessment (SPF, DKIM, DMARC)

Our Methodology

  1. 1
    Asset Discovery — Enumerate all external-facing assets including IPs, domains, and cloud resources
  2. 2
    Vulnerability Scanning — Run authenticated and unauthenticated scans against discovered assets
  3. 3
    Validation — Verify findings to eliminate false positives and confirm true exposure
  4. 4
    Risk Rating — Assign severity scores based on exploitability and business impact
  5. 5
    Reporting — Deliver prioritized findings with remediation guidance
  6. 6
    Ongoing Monitoring — Schedule recurring scans to detect new vulnerabilities as they appear

Deliverables

  • External attack surface map
  • Vulnerability findings report with severity ratings
  • Prioritized remediation roadmap
  • Recurring scan schedule and trend reporting
  • Executive summary for stakeholder communication

Who Needs This

Organizations of all sizes that need visibility into their external attack surface — especially those with cloud infrastructure, multiple domains, or compliance requirements mandating regular vulnerability assessments.
