What does External Pentesting Involve?

External penetration testing involves an assessment of your organisation’s public facing infrastructure, including web servers, firewalls, and cloud services. This type of testing is crucial for identifying vulnerabilities that could be exploited by attackers who are attempting to gain access to your systems from the outside.

Asset Discovery and Enumeration

We enumerate and discover your public facing assets, including servers, firewalls, and cloud services.

We use a combination of automated tools and manual techniques to ensure the breadth and depth of coverage you deserve.

Vulnerability Detection

We perform manual vulnerability enumeration, supplemented with automated vulnerability scans to identify weaknesses in your infrastructure components.

This includes identifying outdated software, misconfiguration, and other common security issues that could be exploited by attackers.

Exploitation and Lateral Movement

We attempt to exploit discovered vulnerabilities to validate their existence and assess the real-world impact.

This includes testing for privilege escalation pathways and lateral movement opportunities within your network.

FAQs

How do you test for vulnerabilities in external infrastructure?

Our process for testing your external infrastructure incorporates both manual and automated techniques to ensure that our team provides thorough coverage of your perimeter. We start with discovering and enumerating the assets that are exposed to the internet to identify exposed ports and services such as web servers.

We then conduct vulnerability scans in the background to identify known ’low hanging fruit’ vulnerabilities such as missing security patches, outdated software, and general misconfiguration of services. At the same time, our team of ethical hackers will manually probe and test the services to paint more of a picture of what is exposed to the internet.

With this information, we then look to discover vulnerabilities that can be exploited to gain access to your systems or to expose data that could lead to a data breach. Finally, we will attempt to exploit any discovered vulnerabilities to validate their existence and assess the real-world impact they could have on your organisation. This may include testing for privilege escalation pathways and lateral movement opportunities within your network.

What types of assets do you test in external infrastructure penetration testing?

We can test a wide range of assets that are exposed to the internet, including but not limited to:

  • Web servers and applications
  • Remote access solutions
  • FTP servers
  • Cloud infrastructure (AWS, Azure, Google Cloud)
  • Email servers
  • VPN endpoints

Our goal is to provide a thorough assessment of your perimeter security posture by identifying potential vulnerabilities across all of your public facing assets.

What is the typical duration of an external infrastructure penetration test?

The duration of an external infrastructure penetration test can vary based upon the size and complexity of your network, but will be based upon the number of assets provided to be tested. Typically, a small number of assets (for example, 5-10 IP addresses) can be tested in 1-2 days, while larger networks with more assets may take several days or weeks to complete.

How do you report the findings from an external infrastructure penetration test?

We provide detailed reports that includes an executive summary, technical findings, and remediation recommendations. The report will outline the vulnerabilities discovered, their potential impact, and guidance on how to remediate or mitigate them. We also offer a collaborative platform where you can track the progress of remediation efforts and communicate with your team.
