Offensive Security

External Network Penetration Testing

Evaluate internet accessible systems from the perspective of an external attacker.

Service Overview

A focused technical assessment with clear outcomes

External network penetration testing assesses the systems and services an attacker can reach from outside your organization. Within an agreed scope, NetPhantom identifies exposed attack surfaces, validates security weaknesses and evaluates whether individual issues can be combined into meaningful attack paths.

Every engagement begins with an agreed scope, written authorization and clear rules for testing. The exact activities depend on the systems, objectives and constraints established with the client before work begins.

Areas of Focus

What we assess

Testing is tailored to the engagement. Relevant areas can include the following.

Public IP addresses and exposed hostsIncluded where relevant to the agreed scope, environment and engagement objectives.
Internet accessible services and management interfacesIncluded where relevant to the agreed scope, environment and engagement objectives.
Authentication and access controlsIncluded where relevant to the agreed scope, environment and engagement objectives.
Network and service configurationIncluded where relevant to the agreed scope, environment and engagement objectives.
Known vulnerability exposure where applicableIncluded where relevant to the agreed scope, environment and engagement objectives.
Attack paths that could enable unauthorized accessIncluded where relevant to the agreed scope, environment and engagement objectives.
TESTING METHODOLOGY

External penetration testing methodology

Testing is performed within an agreed scope and authorization so internet exposed systems can be evaluated in a controlled and traceable manner.

01
Scope and authorization

Confirm written authorization, target ranges, exclusions, testing windows and engagement constraints.

02
External reconnaissance

Identify reachable hosts, exposed services and the attack surface visible from outside the organization.

03
Vulnerability analysis

Analyze exposed technologies, configurations and services for weaknesses that may warrant validation.

04
Controlled validation

Safely validate relevant vulnerabilities and attack paths within the approved rules of engagement.

05
Impact analysis

Assess what validated weaknesses could allow an attacker to access, change or disrupt.

06
Reporting and retest

Document evidence and remediation guidance, then identify findings appropriate for validation after fixes are completed.

Reporting and Deliverables

Clear findings your team can act on

Reporting is designed for both technical teams and business decision makers. Findings are supported by context and organized so remediation can be prioritized.

Executive and technical findings
Evidence supporting validated vulnerabilities
Severity and impact analysis
Attack path context where identified
Remediation guidance
Retesting options after corrective action
Remediation and Validation

From finding to corrective action

NetPhantom does not treat delivery of the report as the end of the conversation. Findings are explained, questions are addressed and remediation priorities are clarified. Where appropriate, retesting can be used to confirm that corrective actions have addressed the validated issue.
