Types of Network Penetration Testing
Network Penetration Testing, also called Infrastructure Penetration Testing, includes Internal and External testing to assess your network security posture comprehensively using top penetration testing tools.
Internal Penetration Testing
An internal penetration test evaluates what a potential attacker could accomplish after gaining initial access to your internal network and identifies insider threats. This simulation helps uncover risks posed by insider threats, including malicious employees, compromised internal devices, or unintentional security lapses.
External Penetration Testing
An External Network Penetration Test targets perimeter security, identifying vulnerabilities in public-facing assets like web servers and DNS using best network penetration testing tools.
Network Penetration Testing Process
Scoping and Planning
We begin with a comprehensive assessment of your organization's network security infrastructure, including system architecture, critical assets, and connected applications. Based on your business needs, we define clear testing objectives, determine the scope of the penetration test, and tailor our strategy.
New Attack Surfaces Require a New Approach to Testing
As cyber threats evolve, DefenceRabbit’s network penetration testing process uses advanced tools and techniques to identify vulnerabilities and strengthen your network security posture.
Uncover Network Entry Points
Our certified penetration testers use top network penetration testing tools to simulate cyberattacks, evaluating firewalls, routers, and network configurations to reveal perimeter security weaknesses and vulnerabilities.
Identify Internal Network Vulnerabilities
Effective cybersecurity protection goes beyond perimeter defense. Our tests explore internal network segments to uncover overlooked vulnerabilities like weak segmentation, insufficient internal firewall rules, or lax access control policies.
Prioritize Remediation Efforts
We don’t just report vulnerabilities—we rank them based on risk severity, potential business impact, and proximity to critical assets. This targeted approach helps your team focus resources on high-priority threats.

FAQ’s
Frequently Asked Questions
What is the purpose of a network penetration test?
A network penetration test is a strategic security assessment conducted by ethical hackers to identify and exploit vulnerabilities within an organization’s IT infrastructure. The goal is to uncover weaknesses before malicious attackers do, helping businesses strengthen their cybersecurity defenses.
This testing covers both on-premises and cloud environments, including critical components like routers, firewalls, switches, and perimeter security controls. By simulating real-world attack scenarios, penetration testing evaluates how well your network can withstand external and internal threats, ultimately safeguarding sensitive data and preventing costly breaches.
Can an internal pen test be performed remotely?
In many cases, an internal penetration test can be performed remotely via a VPN connection, allowing penetration testers to assess vulnerabilities within your internal network without being physically on-site. However, it is generally recommended to conduct internal pen testing on-premises for the most accurate and comprehensive evaluation.
If your organization’s network is segmented (divided into different subnets or areas), determining the best physical location for the test may require expert guidance. Some areas of the network may be harder to access remotely or may require specific permissions to evaluate effectively.
By ensuring the right approach and location, you can ensure that the test comprehensively identifies internal vulnerabilities and helps strengthen your network security.
How are pen test findings reported?
The results of a penetration test are reported through a comprehensive, structured document designed to clearly communicate findings to both technical and non-technical stakeholders.
Each Defence penetration test includes a detailed written report that covers:
• Vulnerabilities discovered: A thorough listing of all security weaknesses identified during the test.
• Risk level: A clear evaluation of the potential impact of each vulnerability, categorized based on severity.
• Exploitation difficulty: Insight into how easily each vulnerability could be exploited by an attacker.
• Recommendations for remediation: Actionable steps to help organizations address the vulnerabilities swiftly, ensuring security improvements.
This structured reporting ensures that all stakeholders can understand the critical findings and take appropriate action to mitigate risks.
What is the difference between internal pen testing and external pen testing?
Internal Penetration Testing focuses on identifying vulnerabilities within an organization’s internal network. This type of test simulates an insider threat, whether from an employee or an attacker who has already gained access to the network. The goal is to uncover weaknesses in internal systems, such as misconfigured firewalls, unauthorized access to sensitive data, and poor network segmentation.
On the other hand, External Penetration Testing is performed remotely by ethical hackers who simulate external cyber-attacks. The goal is to identify vulnerabilities in internet-facing assets, such as web servers, email servers, and FTP servers. This type of test assesses the effectiveness of perimeter defenses, such as firewalls and intrusion detection systems, in preventing unauthorized access from external sources.
What information is required to scope a network penetration test?
The information required to scope a network penetration test depends on whether an internal pen test or external pen test is needed.
Key details typically requested by a network pen test provider include:
• Total number of internal IPs: The range of IP addresses within the internal network to be tested for vulnerabilities.
• Total number of external IPs: The IPs that face the internet and require testing for perimeter security risks.
• Subnets: Information about the network’s subdivision to ensure thorough testing of different network segments.
• Physical locations: The number of physical sites to be included, as this may affect the test’s scope and approach, especially for testing internal network access.
By providing this detailed information, the scope of the penetration test can be accurately defined, ensuring comprehensive coverage and the identification of potential vulnerabilities.
What We Check During Network Penetration Testing?
1. Network Infrastructure
We thoroughly assess your network infrastructure, including routers, switches, firewalls, and VPNs, to identify potential vulnerabilities that attackers could exploit. Our team evaluates network topologies to ensure effective segmentation and configuration, reducing the attack surface.
2. System Configurations
Penetration testers examine your system configurations, including operating systems, applications, and devices, to ensure they are securely configured. This involves checking for default settings, unnecessary services, and patch management processes that could expose vulnerabilities.
3. Security Policies and Procedures
We review your organization’s security policies and procedures to ensure they align with industry best practices. This includes examining incident response plans, access control policies, and employee training programs, ensuring there are no gaps that could be exploited by malicious actors.
4. Encryption Practices
Our team assesses the strength and implementation of your encryption practices, ensuring data at rest and in transit is properly protected. We check for vulnerabilities in SSL/TLS configurations, improper key management, and weak encryption protocols that could leave sensitive data exposed.
5. Third-Party Integrations
Penetration testing also covers any third-party integrations that may present additional attack vectors. We evaluate the security posture of external partners, contractors, and vendors, ensuring that their systems don’t introduce new vulnerabilities into your network environment.
