External Network Penetration Testing



If your company’s network perimeter is not properly set up, patched, and maintained, it may be exposed to breaches. It’s vital to have specialized skills to secure your internet-facing infrastructure. This includes operating systems, cloud services, servers, and firewalls. Penetration testing of your external network can help identify security vulnerabilities that unauthorized individuals can exploit to obtain access to, destroy, or exploit your company’s mission-critical data.

What is External Network Penetration Testing?

An external network penetration test identifies weaknesses in perimeter security, discovers public-facing vulnerable systems, and includes exploitation of such systems. These assessments can include a particular IP range or in-depth research using open-source intelligence (OSINT) techniques. These tests also map attack paths that lead to internal assets and validate firewall configurations to reduce the overall attack surface. The main goal of these tests is to uncover security loopholes in your external infrastructure.

How do we carry out an External Network Pen Test?

At Redfox Security, an external network penetration test reveals security vulnerabilities that attackers can leverage to steal company data. Our comprehensive reports address encryption, patching, and other vulnerabilities while addressing an organization’s preparedness against external network breaches. We use a sophisticated pen testing methodology to address an organization’s external security posture. Our external pen test approach includes (but not limited to) the following:


We collaborate closely with you to define the scope of the test, including the target systems, desired testing methodologies, and compliance requirements. This ensures that our testing aligns with your specific needs.


Our experts conduct thorough reconnaissance to gather information about your external network infrastructure. This includes identifying IP ranges, DNS information, open ports, and other publicly available data to understand potential entry points for attackers.

Vulnerability Analysis

We leverage advanced scanning and enumeration techniques to identify vulnerabilities present in your external network infrastructure. This includes vulnerability assessment of web applications, network devices, and other internet-facing systems.


Our ethical hackers simulate real-world attacks to exploit identified vulnerabilities and gain unauthorized access to your external systems. We employ manual and automated techniques to validate the severity and impact of each vulnerability.

Reporting and Recommendations

We provide a comprehensive report detailing the vulnerabilities discovered, their potential impact, and actionable recommendations for remediation. Our team is available to assist you in implementing the necessary security measures and addressing any identified vulnerabilities.

The testing will identify possible remote attack paths. We will show you how to reproduce the findings as well as give you suitable recommendations. External network penetration testing should be done at least once a year or at the bare minimum after substantial network upgrades to internet-facing systems and services.
