Internal Network Penetration Testing
You might be wondering: does my internal network need a pen test? Whether it’s time for your annual compliance check or you want peace of mind after recent changes, the answer is probably yes. Internal penetration testing shows you exactly what a hacker could reach if they got inside your network – helping you discover whether they could move between systems, access sensitive data, and identifying vulnerabilities before they become costly breaches.
What is Network Internal Penetration Test?
Internal network penetration testing methodology involves a thorough security assessment that checks the security of an organisation’s internal network environment.
The goal of internal network infrastructure penetration testing is to find potential vulnerabilities that attackers could exploit. By identifying these weaknesses before malicious actors do, organisations can prioritise security improvements and strengthen their overall Cyber Security posture.
Certified by CREST and Offensive Security, our qualified testers employ real-world hacking techniques to uncover profound insights.
How Does Internal Pen Testing Work?
During an internal network vulnerability assessment and penetration testing, our team of penetration testers simulates real-world attacks to evaluate your internal network security. We perform vulnerability scanning to identify weaknesses, misconfigurations, and exploitable vulnerabilities throughout your internal network, approaching it from the perspective of a malicious attacker.
The scope of internal network pen testing typically includes various components within the network, such as:
- Servers
- Workstations
- Network devices (routers, switches, firewalls)
- Internal applications
- Databases
Pen testers employ a combination of automated tools and manual techniques to perform this comprehensive assessment. Once vulnerabilities are identified, we provide detailed recommendations to address them, helping you strengthen potential security weak points before they can be exploited.
What Does Internal Network Pen Testing Services Involve?
- Automated testing: Internal penetration testing starts with automated tools that simulate attack scenarios to uncover common vulnerabilities across your network, systems, and applications. These tools are effective at identifying known issues but have their limits — they can’t replicate the creative thinking hackers use to navigate complex environments.
- Combined approach: That’s why the most effective internal testing combines automation with manual testing by certified security professionals. These experts use up-to-date attack techniques and creative problem-solving to uncover vulnerabilities unique to your organisation and network.
- Realistic exploitation: Our testers don’t just identify weaknesses — they attempt to exploit them in a safe, controlled manner (with your permission). This shows you what a real attack could look like and how an attacker might move through your network.
The Benefits of Securing Your Internal Network
Proactive Risk Management:
By identifying weaknesses before others can exploit them, you adopt a proactive approach to Cyber Security. This helps prevent breaches that could disrupt operations or compromise sensitive data.
Tailored Security Improvements:
The insights from an internal network pen test help you decide where to allocate resources. This way, you can focus on the areas that need the most attention.
Updated Regulatory Compliance:
Many industries require regular security assessments to comply with regulations. Internal network penetration testing can help ensure you meet these standards and avoid costly penalties.
Improved Incident Response:
Knowing your internal network’s weaknesses helps you strengthen your incident response plans. This way, if an attack happens, you can respond quickly and effectively.
What Does The Network Pen Test Report Include?
Once our team of experts has completed the network penetration testing, you’ll receive a detailed report. This report not only highlights the identified threats but also prioritises them, providing you with clear, actionable remediation advice to accelerate your security improvements.
Our network pen test reports feature:
- A comprehensive list of all risks based on your current server, application setup, and configuration
- Identified vulnerabilities and details on running services for your servers and applications
- A summary of how each security issue was exploited during testing
- Step-by-step remediation guidance
- Recommended actions for both the short-term and long-term
Each testing scope is tailored to your organisation.
