Internal Infrastructure Assessment
A penetration test from inside your network, simulating the threat posed by a compromised device, a malicious insider, or an attacker who has already breached your perimeter.

What is Internal Penetration Testing
Perimeter defences are necessary but not sufficient. Once an attacker is inside your network, the question becomes how far they can go. An Internal Infrastructure Assessment answers that question by simulating an attacker with a foothold on your internal network and testing how far they can escalate privileges, move laterally, and reach sensitive systems and data.
This assessment is particularly relevant for organisations running Active Directory environments, where misconfigurations and privilege escalation paths are common and the consequences of a full domain compromise are severe.
What we test
The assessment is conducted from a position of internal network access, typically with a standard domain user account to simulate a realistic threat scenario. From that starting point, our assessors attempt to identify misconfigurations, exploit vulnerabilities, abuse Active Directory relationships and permissions, escalate privileges, and move laterally across the environment.
Common areas of focus include Active Directory configuration and attack paths, Kerberos abuse, NTLM relay opportunities, weak service account configurations, unpatched internal systems, exposed management interfaces, and network segmentation weaknesses. Where domain administrator access is achieved, we document the path taken to get there in full.
What you receive
A detailed report covering the attack paths identified, the techniques used, findings by severity, and remediation guidance prioritised by risk. For organisations running Active Directory, we provide specific guidance on the configuration changes and hardening steps that would have prevented or significantly impeded the attack paths we found.
