Internal Network Penetration Test

In today’s evolving threat landscape, external defenses alone are not enough to protect your organization. Internal network vulnerabilities—whether from insider threats, compromised credentials, or misconfigured systems—can lead to devastating breaches. At Tungsten Secure, our Internal Network Penetration Testing service simulates real-world attack scenarios to expose weaknesses within your internal infrastructure before malicious actors can exploit them.

Why Internal Penetration Testing Matters

Many organizations focus heavily on perimeter security, assuming that once an attacker bypasses external defenses, little can be done to stop them. However, over 34% of data breaches involve internal actors, whether through negligence, malicious intent, or compromised accounts. Without proper internal security controls, attackers who gain initial access can move laterally, escalate privileges, and exfiltrate sensitive data undetected.

Our Internal Penetration Testing service emulates the tactics of real adversaries, assessing how far an attacker could penetrate your network once inside. By identifying and remediating these risks, you can strengthen your security posture, maintain compliance, and prevent costly breaches.

What Is Internal Network Penetration Testing?

Unlike external penetration testing, which evaluates internet-facing assets, internal pen testing is conducted from within your network, simulating threats such as:

Malicious insiders attempting unauthorized data access or privilege escalation

Compromised endpoints (e.g., via phishing) acting as entry points for attackers

Misconfigured systems allowing lateral movement across internal segments

Our experts meticulously assess your servers, workstations, databases, internal applications, and shared resources using a blend of manual exploitation techniques and advanced automated tools. This approach uncovers vulnerabilities that automated scans alone may miss.

Key Benefits of Our Internal Penetration Testing

1. Identify and Exploit Internal Vulnerabilities

We uncover weaknesses in patch management, weak credentials, improper access controls, and other security gaps that could be exploited from within.

2. Test Lateral Movement & Privilege Escalation

Our team simulates how an attacker could pivot across systems, escalate privileges, and access critical data.

3. Evaluate Network Segmentation & Security Policies

We assess whether your internal segmentation effectively contains threats or if weak policies allow unrestricted movement.

4. Simulate Real-World Insider Threats

By emulating malicious or negligent insider actions, we help you understand and mitigate internal risks.

5. Actionable Reporting & Remediation Guidance

Our detailed reports provide clear, prioritized recommendations to strengthen defenses and reduce risk.

Our Methodology: A Structured Approach to Security

At Tungsten Secure, we follow a proven, systematic process aligned with MITRE ATT&CK, NIST, and OSSTMM frameworks:

Scoping & Planning – Define objectives, rules of engagement, and critical systems to assess.

Reconnaissance & Enumeration – Map internal networks, identify active systems, and detect potential attack paths.

Exploitation & Escalation – Safely exploit vulnerabilities to assess real-world impact.

Post-Exploitation Analysis – Determine the extent of access an attacker could achieve.

Comprehensive Reporting & Debrief – Deliver a strategic roadmap for remediation.

Why Choose Tungsten Secure?

With cyber threats growing in sophistication, organizations need a partner that combines technical expertise with real-world attack simulation experience. Our certified penetration testers go beyond automated scans, applying hands-on adversarial techniques to expose risks that others might miss.

Whether you’re looking to meet compliance requirements (e.g., PCI DSS, ISO 27001, HIPAA) or proactively strengthen security, our Internal Network Penetration Testing provides the insights needed to safeguard your business from within.
