Network Penetration Testing
Internal and external network exploitation and segmentation validation.
Internal and external network testing covering exposed services, patch posture, credential attacks, Active Directory and segmentation.
- Typical timeline
- Typically 1–3 weeks depending on host count
- Business benefit
- Understand exactly how far an attacker moves after the first foothold.

Overview
What Network Penetration Testing covers
Network testing answers a direct question: from a given starting point, what can an attacker reach? We chain misconfigurations, weak credentials and unpatched services into demonstrated impact.
Both perimeter and internal perspectives are available, and segmentation claims are validated rather than assumed.
The problem we solve
Flat internal networks and legacy trust relationships turn a single compromised endpoint into domain-wide access.
Scope & outcomes
What we test and what you receive
Scope coverage
- External perimeter and exposed service discovery
- Patch and configuration weaknesses
- Credential attacks, spraying and relay
- Active Directory attack paths and delegation abuse
- Lateral movement and privilege escalation
- Segmentation and firewall rule validation
- Legacy protocol and service exposure
- Backup, hypervisor and management plane exposure
Key benefits
- Demonstrated attack paths to critical systems
- Validated segmentation and containment
- Prioritised hardening of identity infrastructure
- Reduced blast radius of endpoint compromise

FAQ
Network Penetration Testing questions
External testing measures perimeter exposure; internal testing measures blast radius. Most organisations benefit from both, sequenced in one engagement.
We exploit within agreed rules of engagement, because demonstrated impact drives remediation far more effectively than theoretical severity.
