Network Penetration Testing
External perimeter and internal Active Directory testing — the credential paths, lateral movement and privilege escalation that turn a foothold into domain compromise.
What it covers
Network testing answers two questions. From outside: what is exposed, and can it be used to get in? From inside — the assumed-breach position that matters most, because phishing succeeds eventually — how far does a single compromised workstation get? In most Active Directory environments the answer is further than anyone expects, through misconfigurations that no patch fixes. Testing follows NIST SP 800-115.
What we test
Every engagement is scoped to your environment, but these are the areas a Network test engagement covers.
External perimeter
Internet-facing services, exposed admin interfaces, and the forgotten host that becomes the way in.
Active Directory
Kerberoasting, credential relay, delegation abuse and the escalation paths to Domain Admin.
Lateral movement
How a single foothold spreads — shared local admin passwords, cached credentials, over-broad shares.
Segmentation
Whether the boundaries meant to contain a breach actually hold, including any cardholder or OT zones.
Privilege escalation
Local and domain escalation from the position a real intrusion would start in.
How the engagement runs
The same defensible sequence every time.
Scoping and a fixed-price quote, reconnaissance and threat modeling, manual exploitation with same-day escalation of critical findings, a report your engineers and auditors can both use, and a free retest once fixes ship.
Network test, answered
What is assumed-breach testing?
We start from the position of an attacker who already has a foothold — a compromised workstation or a set of standard-user credentials — because that is where real intrusions begin. It tests your internal resilience rather than just the perimeter.
Is on-site access required?
For internal testing we usually deploy a small device or a cloud connector so we can test remotely; genuine on-site work is arranged where wireless or physical scope requires it.
