Penetration Testing

External Network Penetration Testing

Identify what adversaries can see and exploit from the internet. Our external network assessments evaluate your perimeter defenses with audit-ready evidence.

  • What we test: Internet-facing assets, exposed services, remote access paths, and perimeter configurations
  • Outcomes: Prioritized external risks with remediation guidance and asset inventory
  • Deliverables: Executive summary, technical report, and Opsfolio Evidence Pack

Who It's For

  • Organizations with internet-facing infrastructure
  • Companies preparing for SOC 2 or ISO 27001 audits requiring external testing
  • Teams validating perimeter defenses after infrastructure changes
  • M&A due diligence requiring external attack surface assessment
  • Government contractors meeting CMMC external testing requirements

What We Test

We go beyond automated vulnerability scanning with manual validation and exploitation attempts. Our testers evaluate your external attack surface as a real adversary would.

Internet-facing perimeter assessment
Exposed services and port enumeration
Service misconfigurations and default credentials
Identity and remote access exposure paths
Public-facing infrastructure vulnerabilities
DNS and email security configuration
SSL/TLS configuration analysis
Network device security assessment

Our Methodology

A systematic, defensible approach that satisfies both engineering teams and auditors

1

Scoping & ROE

Define scope, rules of engagement, and testing windows with clear authorization documentation.

2

Recon & Discovery

Identify attack surface, enumerate assets, and gather intelligence through passive and active reconnaissance.

3

Testing & Exploitation

Execute authorized testing using manual techniques and code-assisted analysis to identify vulnerabilities.

4

Evidence Capture

Document findings with screenshots, command outputs, and reproducible steps for validation.

5

Reporting & Readout

Deliver executive summary and technical findings with risk-ranked recommendations and control mappings.

6

Retest & Verification

Validate remediation efforts and provide verification evidence for audit and compliance purposes.

Deliverables

Actionable outputs for infrastructure teams and compliance stakeholders.

Executive Summary

External attack surface overview with prioritized risks for leadership

Technical Findings Report

Detailed perimeter vulnerabilities with remediation steps

Opsfolio Evidence Pack

Audit-ready artifacts documenting external testing scope and findings

Retest Verification

Validation that external exposures have been remediated

Asset Inventory

Discovered external assets and services for ongoing monitoring

The Opsfolio Difference

Opsfolio Evidence Pack

Every engagement produces an Evidence Pack that transforms point-in-time testing into continuous, auditable compliance evidence. This is what separates us from vendors who deliver a PDF and disappear.

Audit-Ready Artifacts

The Evidence Pack integrates directly with Opsfolio Suite, providing auditors with verifiable, timestamped evidence that supports continuous compliance—not just annual checkbox exercises.

Note: Evidence supports compliance efforts but does not constitute certification. Control mappings are provided as guidance.

Signed Rules of Engagement

Authorized scope documentation with testing windows and boundaries

Testing Window Logs

Tester identities, roles, and toolchain summary with timestamps

Findings with Unique IDs

Each finding tagged with severity rationale and risk acceptance workflow

Evidence Screenshots

Command outputs and visual proof, redacted as needed for sensitivity

Remediation Verification

Before/after evidence documenting successful fixes

Control Mappings

High-level mappings to SOC 2, ISO 27001, CMMC, and HIPAA controls
