External Infrastructure Penetration Testing


External infrastructure penetration testing aims to assess the security of an organisation’s external-facing systems, networks, and applications. This includes anything accessible from outside the organisation’s internal network.

By conducting external infrastructure penetration testing, organisations can identify and address security weaknesses before they are exploited by malicious actors, thereby reducing the risk of data breaches, financial losses, and damage to reputation.

What are the benefits of external infrastructure testing?

External infrastructure pen testing aims to identify vulnerabilities affecting an organisation’s external-facing systems, strengthen its security posture, reduce risk, and enhance resilience in the face of evolving cyber threats.

  • External infrastructure testing allows organisations to detect potential weaknesses in their external-facing systems, such as web servers, firewalls, and applications. By uncovering vulnerabilities early, organisations can take steps to address them, reducing the likelihood of successful cyber attacks.
  • By identifying and addressing vulnerabilities, organisations can significantly reduce the risk of data breaches, financial losses, and reputational damage. Securing external systems helps protect sensitive data from unauthorized access and exploitation, safeguarding both the organisation and its stakeholders.
  • Many industries are subject to regulatory requirements mandating regular security assessments. By conducting these tests, organisations can ensure compliance with relevant regulations and standards, avoiding potential penalties and legal consequences.
  • External infrastructure testing is an essential component of a comprehensive cybersecurity strategy. By assessing and strengthening external-facing systems, organisations can strengthen their resilience against evolving cyber threats, by staying ahead of attackers and minimizing the impact of potential security incidents.

Technical delivery

LRQA Nettitude offers a thorough assessment of your organisation’s internet-facing infrastructure. These services often provide an initial foothold into a target organisation for a malicious actor. We specialise in the accurate discovery of all services provided by your external infrastructure, and where appropriate will use exploitation techniques to accurately demonstrate the severity of any findings or misconfigurations.

External Infrastructure engagements often include the following phases:

  • Discovery, reconnaissance and enumeration
  • Vulnerability analysis
  • Manual exploitation
  • Post-exploitation

To ensure comprehensive results, our engagements strive for both breadth and depth in findings. This requires a blend of manual and automated tools and techniques tailored to each engagement’s requirements. We deploy a range of toolsets, from well-configured off-the-shelf software to bespoke solutions, depending on the task. Our methodology progresses from initial discovery exercises to thorough exploitation, ensuring a holistic assessment of the target environment.

Reporting and output

Penetration tests need to result in clear and actionable output. LRQA Nettitude delivers a management report and a technical report at the end of each engagement. The management report is designed to be consumed by a business audience and describes the engagement in terms of risk. The technical report is typically a longer document that describes each of the findings in detail, along with appropriate remedial advice. These reports are subjected to a rigorous quality assurance process before final delivery.

Remedial advice

We can provide robust and actionable remedial advice for all levels of vulnerability. We understand that one of the most valuable portions of any engagement is the formulation of remedial and preventative strategies. Our consultants are on hand, both during and after the engagement, to provide in-depth guidance based on years of unique experience.

Debriefs and beyond

LRQA Nettitude believes that it is important to ensure that full comprehension of the engagement has been achieved. All penetration test engagements come with a debrief or ‘readout’ as standard. The reports will be delivered in advance of the debrief to give time for the organisation to digest the content and formulate any questions or thoughts ahead of time.
