External Security Assessment

An External Security Assessment examines your organization's publicly accessible attack surface from an outside perspective.

The goal is simple:

Identify what is exposed, determine what can be learned about it, and identify security issues worth addressing.

  • We identify publicly associated infrastructure and build an inventory of externally accessible assets.

    This may include:

    • Domains and subdomains

    • Public IP addresses

    • Internet-facing hosts

    • DNS records

    • Web applications

    • Other publicly attributable infrastructure

  • Identified hosts are evaluated for externally accessible services and protocols.

    We examine:

    • Open TCP and UDP ports

    • Running services

    • Service and software versions

    • Unnecessary external exposure

    • Internet-facing administrative interfaces

  • Public-facing web applications are reviewed for common security issues and areas of concern.

    Testing may include:

    • Security configuration review

    • Common web application vulnerabilities

    • Authentication and authorization observations

    • Security headers

    • Information disclosure

    • Exposed files and resources

    • Technology and framework identification

  • Identified software and services are evaluated against publicly known vulnerabilities and security advisories.

    Findings are reviewed in context rather than simply reporting automated scanner output.

  • We examine information that a potential attacker can obtain through publicly accessible systems and services.

    This can include:

    • Technology and infrastructure disclosures

    • Publicly exposed files

    • DNS and certificate information

    • Software fingerprints

    • Other information that meaningfully expands the external attack surface

  • Every assessment produces a written report containing:

    01 — Executive Summary
    A concise overview of the organization's external security posture and significant findings.

    02 — External Asset Inventory
    The internet-facing assets identified during the assessment.

    03 — Findings
    Documented security issues with severity, affected assets, evidence, and technical explanation.

    04 — Remediation Recommendations
    Practical steps for reducing exposure and addressing identified issues.

  • External assessments are performed against publicly accessible infrastructure authorized by the client.

    Included:
    External reconnaissance, enumeration, vulnerability identification, and security testing of authorized public-facing assets.

    Not included:
    Internal network penetration testing, credentialed testing, social engineering, physical security testing, or attempts to obtain unauthorized internal access.

    All testing is performed according to an agreed scope and rules of engagement.
