Internal Network
Penetration Testing.
Identify and eliminate security weaknesses within your internal network before they can be exploited by malicious insiders or attackers with unauthorized access.
What is Internal Network Penetration Testing?
Internal Network Penetration Testing simulates an attacker who has gained access to your organization's internal environment—such as through a successful phishing attack, a rogue device, or a malicious insider. The assessment evaluates the security of internal systems, Active Directory, servers, workstations, network devices, and user privileges to uncover vulnerabilities that could lead to lateral movement, privilege escalation, or sensitive data exposure.
Why Internal Testing
Matters
Detect Insider Threats
Identify vulnerabilities that could be exploited by malicious or careless employees.
Protect Active Directory
Secure the core of your network by finding flaws in AD configuration and privileges.
Identify Privilege Escalation Paths
Discover how a low-privileged user could gain administrative control.
Prevent Lateral Movement
Stop attackers from moving freely between systems after an initial compromise.
Secure Critical Assets
Ensure your most sensitive data and servers are properly protected from internal access.
Reduce Business Risk
Minimize the potential impact of a successful phishing attack or insider compromise.
Validate Network Segmentation
Verify that network controls effectively isolate sensitive environments.
Improve Incident Readiness
Help your SOC team identify gaps in internal monitoring and detection capabilities.
Roadmap.
A clear, methodical pathway from initial consultation to final delivery, structured for maximum impact and transparency.
Scoping & Planning
Define the testing boundaries, acceptable activities, and objectives.
Network Enumeration
Map the internal network architecture, active subnets, and live hosts.
Host Discovery
Identify operating systems, open ports, and running services on internal systems.
Vulnerability Assessment
Scan internal assets to identify missing patches and common misconfigurations.
Credential & Access Review
Search for exposed credentials, weak passwords, and open file shares.
Manual Penetration Testing
Attempt to safely exploit identified vulnerabilities to validate risk.
Privilege Escalation
Execute attacks to elevate access rights from a standard user to a domain administrator.
Lateral Movement Simulation
Demonstrate how an attacker could move between systems to reach critical assets.
Reporting & Remediation
Deliver a detailed report prioritizing risks with actionable mitigation steps.
Retesting
Verify that vulnerabilities have been effectively patched and controls improved.

Why It Matters
Internal networks are often less fortified than external perimeters, operating on the assumption of a trusted environment. By simulating the tactics, techniques, and procedures (TTPs) of real-world adversaries, we identify the exact paths an attacker would take if they breached your defenses or if an insider turned malicious.
