Internal Network Penetration Testing

Assess the security of your internal environment from an attacker’s perspective

Once an attacker gains access to your internal network, the real risk begins. Internal systems are often more trusted, less monitored, and more vulnerable to privilege escalation and lateral movement.

This service evaluates how an attacker could move within your environment, escalate privileges, and access sensitive systems after initial access has been obtained.


What This Service Covers

An internal network penetration test simulates a realistic post-compromise scenario. Testing is conducted from within your network to identify weaknesses in systems, configurations, and access controls.

This includes:

  • Internal host and service enumeration
  • Credential discovery and reuse
  • Privilege escalation techniques
  • Lateral movement across systems
  • Identification of sensitive data exposure
  • Misconfigurations in internal services and infrastructure

Active Directory Security Assessment

Active Directory is often the backbone of internal environments and a primary target for attackers. Misconfigurations or weak controls within Active Directory can allow attackers to escalate privileges and gain widespread access.

This assessment places a strong focus on identifying weaknesses in your domain environment, including:

  • Weak or misconfigured user and group permissions
  • Privilege escalation paths within the domain
  • Kerberos-related attacks such as ticket abuse
  • Credential exposure and reuse across systems
  • Delegation misconfigurations
  • Trust relationships and domain misconfigurations

The goal is to determine how an attacker could move from a low-privileged user to high-level access within the domain.


Internal Services and Protocols

Beyond Active Directory, internal environments rely on a variety of services and protocols that can introduce risk if not properly secured.

Testing may include:

  • SSH services and key or credential weaknesses
  • FTP services and insecure file access or anonymous authentication
  • SMB shares and file permission issues
  • Remote management services such as RDP and WinRM
  • Database services and internal application interfaces
  • Network segmentation and access control weaknesses

These components are evaluated to understand how they contribute to lateral movement and overall risk.


Who This Is For

This service is ideal for organizations that:

  • Have an internal network with multiple users and systems
  • Use Active Directory or similar identity management systems
  • Want to understand the impact of a potential internal compromise
  • Need to validate internal security controls and segmentation

What You Will Receive

After the engagement, you will receive:

  • A detailed report of identified vulnerabilities and attack paths
  • Clear explanation of how access could be escalated within your environment
  • Prioritized remediation guidance
  • Insight into how your internal defenses perform under realistic conditions

Why This Matters

Many breaches do not stop at initial access. Attackers rely on internal weaknesses to expand their control, access sensitive data, and maintain persistence.

Understanding how your internal environment can be navigated by an attacker is critical to preventing widespread impact.
