Internal Network Penetration Testing
Assumed-breach, from foothold to domain.
Assumed-breach testing from inside your network: how far an attacker with an initial foothold can move, escalate, and reach your crown jewels, including Active Directory.
What we test
Where we focus
Lateral movement and pivoting
Privilege escalation
Active Directory attack paths
Credential harvesting and reuse
Segmentation and access control
Sensitive data and crown-jewel access
This is part of our Vulnerability Assessment & Penetration Testing service. Retest validation is included at no added cost.
Who it's for
Organizations that want to understand how far an attacker who already has a foothold, whether through phishing, a rogue device, or a compromised host, could move, escalate, and reach critical systems.
FAQ
Common questions
What is internal network penetration testing?
Internal network penetration testing is assumed-breach testing performed from inside the network to measure how far an attacker with an initial foothold can move laterally, escalate privileges, and reach sensitive systems, including Active Directory.
What does assumed breach mean?
Assumed breach is a testing model that starts from the premise that an attacker already has some access, rather than trying to break in from outside. It focuses effort on lateral movement, privilege escalation, and impact, which reflects how many real intrusions actually progress.
Why is Active Directory a focus of internal testing?
Active Directory is the identity backbone of most enterprise networks, so it is a primary target for attackers seeking to escalate to domain-wide control. Testing looks for credential reuse, misconfigurations, and known attack paths that lead from a standard user to administrative access.
