Internal Penetration Testing
Simulate a post-breach scenario to identify how far an attacker can move inside your network.
Book AssessmentEliminating the Blind Spots Within Your Network
Internal Penetration Testing assumes a breach scenario where an attacker has already gained access to your internal network. This service identifies how far an attacker could move, what systems they could access, and how sensitive data could be compromised.
We simulate insider threats, compromised credentials, and rogue devices to test segmentation, access controls, and monitoring capabilities. Our team performs lateral movement, privilege escalation, and data exfiltration techniques to uncover hidden weaknesses.
This service is critical for understanding real-world breach impact and strengthening internal defenses beyond perimeter security.
Key Benefits & Deliverables
Lateral Movement Testing
Identify pathways attackers use to traverse internal networks and reach mission-critical environments.
Active Directory Assessment
Thorough auditing of AD architecture to prevent systemic domain compromise via Kerberoasting, Golden Tickets, and misconfigurations.
Insider Threat Simulation
Determine the exact damage a malicious employee or a compromised low-privilege account can inflict.
Engagement Process
Initial Foothold
Establishing access within the network using a standard non-privileged workstation or compromised credential.
Network Enumeration
Mapping internal subnets, identifying exposed internal portals, databases, and unpatched endpoints.
Privilege Escalation
Attempting to elevate local or domain rights to gain persistent administrative control.
Objective Execution
Simulating safe data exfiltration to demonstrate real business impact prior to comprehensive reporting.
