Internal Network Penetration Test

Your internal network is the backbone of your organisation’s digital operations—but it can also be one of the most vulnerable entry points if left untested. Internal network penetration testing simulates a scenario where an attacker has gained access to your internal environment—whether through a compromised device, malicious insider, or rogue wireless connection—to assess how easily they could escalate privileges, move laterally, or exfiltrate sensitive data.
Our Internal Network Penetration Testing Service is designed to uncover hidden risks within your internal infrastructure, helping you to identify security gaps before they can be exploited. Whether delivered remotely or conducted on-site by our experienced consultants, this service provides a thorough assessment of your internal defences and supports your organisation’s wider security strategy.
This service is particularly valuable for:
- Organisations handling sensitive business-critical, customer, or financial data within internal systems.
- Businesses aiming to meet the technical controls of standards such as Cyber Essentials Plus, ISO 27001, PCI DSS, GDPR, SOC 2, NHS Data Security and Protection Toolkit (DSPT), and NIST.
- IT and security teams looking for expert validation of network segmentation, access control, and endpoint protection.
-
Companies committed to proactively identifying and mitigating internal threats before they can be weaponised.

What’s Included in Our Penetration Testing Service?
- Comprehensive Reconnaissance – We begin with an in-depth reconnaissance phase to map out your attack surface. Using a combination of open-source intelligence (OSINT) and active scanning techniques, we identify publicly exposed assets, entry points, and underlying technologies. This step provides critical insight into potential weaknesses before moving on to deeper analysis.
- Vulnerability Assessment – Once we have a complete picture of your environment, we conduct an extensive vulnerability assessment. This involves identifying misconfigurations, outdated components, security flaws, and weak authentication mechanisms. Our experts use both automated tools and manual techniques to ensure accuracy, eliminating false positives and uncovering vulnerabilities that automated scans often miss.
- Exploitation Testing – To measure the real-world impact of identified vulnerabilities, we perform controlled exploitation in a safe and responsible manner. This process simulates the tactics of real attackers, including attempts to bypass authentication, escalate privileges, exploit misconfigurations, and gain unauthorized access. Every test is conducted carefully to avoid service disruptions while demonstrating the true risk of potential breaches.
- Post-Exploitation Analysis – If a vulnerability is successfully exploited, we assess how far an attacker could move within the system, what data could be accessed, and whether additional security controls prevent lateral movement. This phase highlights the full impact of a potential breach and provides insight into necessary security improvements.
- Detailed Reporting & Remediation Guidance – At the conclusion of the test, we provide a comprehensive report detailing all findings, including vulnerability descriptions, proof-of-concept exploitation, risk ratings, and clear remediation steps. Our actionable recommendations help you strengthen your defenses and prevent future attacks. We also offer post-assessment consultations to support your team in addressing any security gaps effectively.
