Network Penetration Testing

External and internal network penetration testing that validates exposed services, identity attack paths, segmentation, and the controls meant to stop lateral movement.

EXPERT-LED Β· MANUAL VALIDATION

Measure how far a real foothold can travel

A vulnerability list does not explain whether an attacker can move from one exposed service or compromised workstation to privileged access. Network penetration testing validates reachable attack paths, weak identity controls, unsafe trust relationships, and segmentation failures under explicit rules of engagement.

HOW THE TESTING FEELS IN PRACTICE

Network penetration testing, 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.

External attack surface

Validate internet-facing hosts, ports, VPNs, remote administration, email and DNS services, exposed management interfaces, TLS configuration, default content, weak authentication, and patch-related exploitability.

Internal discovery and segmentation

Assess host visibility, VLAN and firewall boundaries, management networks, shared services, name resolution, administrative protocols, and whether a standard user or workstation can reach sensitive systems.

Active Directory and identity

Review domain trusts, privileged groups, service accounts, Kerberos and NTLM weaknesses, delegation, certificate services, password policy, stale identities, local administrator reuse, and practical paths to elevated access.

Credential and privilege risks

Test password spraying only when authorized, exposed secrets, service credentials, weak local permissions, credential material, excessive privileges, unsafe scheduled tasks, and escalation opportunities on reachable hosts.

Lateral movement and trust abuse

Use controlled techniques to validate remote administration paths, relay opportunities, shared credentials, service-to-service trust, jump hosts, and whether security controls detect or prevent movement between zones.

Detection and containment observations

Record which test actions were blocked, alerted, or silently allowed. The engagement is a penetration test rather than a full red-team exercise, but these observations help tune preventive and detective controls.

RULES OF ENGAGEMENT FIRST

Penetration testing methodology

Every phase is designed to produce defensible evidence without taking unnecessary operational risk.

  1. Scope and safety planning

    Define IP ranges, locations, environments, prohibited systems, test windows, source addresses, credentials, escalation paths, and actions requiring separate approval.

  2. Reconnaissance and enumeration

    Map externally visible and internal services, hosts, domains, trust relationships, technologies, and identity surfaces with rate-conscious discovery.

  3. Vulnerability analysis

    Combine scanner coverage with manual verification, configuration review, version analysis, and attack-path reasoning to remove noise before exploitation.

  4. Controlled exploitation

    Use the least disruptive proof needed to validate access, privilege, segmentation, or trust impact. Destructive actions and persistence are excluded unless separately approved.

  5. Attack-path validation

    Where scope allows, chain findings to show practical movement from initial access toward sensitive systems or privileged identities without collecting unnecessary data.

  6. Reporting and retest

    Document evidence, affected assets, root causes, attack paths, and prioritized fixes. Retesting confirms whether controls now break the demonstrated path.

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 tested-scope inventory
  • External and internal exposure observations
  • Prioritized findings with evidence and affected assets
  • Attack-path narrative for chained weaknesses
  • Network, identity, and host-hardening recommendations
  • Retest status and residual-risk notes

COMMON SCOPING QUESTIONS

Network penetration testing FAQ

What is the difference between external and internal network penetration testing?

External testing starts from the internet and focuses on exposed services and perimeter entry points. Internal testing begins from an agreed foothold or network segment and evaluates identity, privilege, segmentation, and lateral movement risks.

Can you test Active Directory?

Yes. An internal scope can include domain enumeration, Kerberos and NTLM weaknesses, service accounts, delegation, certificate services, privileged groups, credential exposure, and practical paths to elevated access.

Do you run denial-of-service tests?

Not by default. Availability testing can cause real disruption, so it is excluded unless a specific technique, target, window, monitoring plan, and stop condition are approved in writing.

Do you need administrator credentials?

No. Black-box, grey-box, and assumed-breach models are possible. Test credentials often improve coverage and allow role-specific validation, but the chosen model depends on the objective and time available.

How is a network pentest different from a vulnerability scan?

A scan identifies probable weaknesses by signature and configuration. A penetration test manually verifies exploitability, evaluates trust and identity controls, and can chain multiple weaknesses to demonstrate meaningful impact.
