Domain and infrastructure discovery
Map domains, subdomains, DNS relationships, certificates, IP space, hosting providers, autonomous systems, cloud endpoints, CDN origins, mail infrastructure, and attributable third parties.
DISCOVERY · EXPOSURE · VALIDATION
External Attack Surface Assessment
External attack surface assessment that discovers internet-facing assets, ownership gaps, exposed services, leaked secrets, and high-value paths for manual validation.
EXPERT-LED · MANUAL VALIDATION
Find the assets an attacker sees before choosing what to test deeply
Organizations accumulate domains, cloud services, staging systems, repositories, SaaS integrations, and abandoned infrastructure faster than inventories stay current. This assessment maps attributable exposure, verifies ownership, and manually validates the risks most likely to become an entry point.
HOW THE TESTING FEELS IN PRACTICE
External attack surface assessment, done by hand
Automation gives coverage. The findings that matter come from someone chaining weak controls together, questioning assumptions, and checking what a motivated attacker could reach next.
- Manual attack-path testing, not a scanner export
- Evidence you can reproduce and hand to engineering
- One retest round after remediation
ASSESSMENT COVERAGE
What the test covers
Coverage is finalized during scoping, then tested with a mix of systematic checks and manual attack-path analysis.
Service and technology exposure
Identify reachable ports, protocols, products, versions, administration panels, remote access, databases, dashboards, development tools, default content, and unexpected internet-facing systems.
Web applications and shadow environments
Find customer applications, APIs, staging, test, preview, legacy, acquisition, partner, and regional environments, then classify authentication, ownership, sensitivity, and likely business purpose.
Cloud and storage exposure
Review public object storage, static sites, serverless endpoints, container registries, exposed metadata, forgotten snapshots, public shares, and infrastructure clues tied to the organization.
Code, secrets, and takeover signals
Search attributable public repositories, packages, configuration, historical artifacts, leaked credentials where legally accessible, dangling DNS, abandoned SaaS references, and subdomain takeover conditions.
Prioritization and manual validation
Rank exposure by ownership confidence, reachability, exploitability, data sensitivity, authentication, known weakness, and business context, then manually validate the agreed high-value targets.
RULES OF ENGAGEMENT FIRST
Penetration testing methodology
Every phase is designed to produce defensible evidence without taking unnecessary operational risk.
Scope and rules of engagement
Agree targets, environments, identities, exclusions, test windows, data handling, escalation contacts, and stop conditions before testing starts.
Architecture and threat review
Map sensitive assets, trust boundaries, data flows, likely attackers, and high-impact misuse cases so the test reflects the product rather than a generic checklist.
Systematic coverage
Use repeatable tooling and standards-aligned checks to cover the agreed surface while recording assumptions, constraints, and evidence.
Manual attack-path testing
Challenge identity, authorization, workflows, configuration, integrations, and chained weaknesses that require human context and adversarial reasoning.
Safe impact validation
Use the minimum proof required to establish exploitability. Destructive actions, persistence, and unnecessary data access stay outside scope unless separately authorized.
Report, remediation, and retest
Deliver risk context, reproduction evidence, root-cause fixes, and a stakeholder walkthrough. One retest round verifies agreed remediation.
ACTIONABLE OUTPUTS
What you receive
The report is written for two audiences: stakeholders who need a clear risk decision and engineers who need enough detail to reproduce and fix the issue.
- Executive summary and risk themes
- Scope, assumptions, exclusions, and coverage record
- Prioritized findings with evidence and reproduction steps
- Business impact and severity rationale
- Root-cause remediation guidance
- Retest status and residual-risk notes
COMMON SCOPING QUESTIONS
External attack surface assessment FAQ
Is this continuous attack surface management?
No. This is a defined point-in-time discovery and validation engagement. A recurring cadence can be agreed, but the service does not claim a continuous monitoring platform.
Will every discovered asset be exploited?
No. Assets are attributed and prioritized first. Manual validation is limited to the targets and techniques authorized in the rules of engagement.
Can takeover and leaked-secret risks be validated?
Yes, using safe proof and explicit authorization. Credentials are not used against third-party systems, and takeover validation stops before claiming or disrupting a production resource.
How is this different from an external network pentest?
Attack surface assessment emphasizes broad discovery, attribution, and prioritization. External network pentesting goes deeper on an agreed inventory to validate service and perimeter exploitability.
