Network Infrastructure & Architecture Penetration Testing

Uncover misconfigurations, privilege gaps, and architectural weaknesses before attackers do.

Your network infrastructure and architecture are the foundation of how your organisation operates, so its security is paramount.

Using industry-recognised methodologies and real-world attack simulations, we provide clear risk ratings, actionable remediation steps, and guidance to strengthen your network design, helping you maintain a secure, resilient environment.

    What is Network Infrastructure & Architecture Penetration Testing?

    Network Infrastructure and Architecture Penetration Testing assesses how well your organisation’s network is designed, configured, and protected against cyber-attacks. It looks for weaknesses in network devices, servers, and overall architecture that could be exploited by attackers.

    There are two types:

    • Internal - Identifies security weaknesses from inside your corporate network by simulating an insider with physical or network access, providing insight into how securely internal systems and devices are configured.

    • External - Assesses the external internet-facing infrastructure of your network, such as your Firewall, VPN endpoints, Web Servers, and Mail Servers for vulnerabilities.

    Why should you conduct Network Infrastructure & Architecture Pen Testing?

    Undetected weaknesses in your network infrastructure can give attackers a foothold into your entire organisation.

    • Identify and remediate misconfigurations, weak controls, and architectural flaws before attackers can exploit them.

    • Proactively uncover vulnerabilities across network components to prevent lateral movement and data compromise.

    • Ensure your network design and configurations align with industry standards and regulatory requirements.

    • Address gaps that could lead to downtime, service disruption, or unauthorised access.

    Endpoint Security Reviews

    Assesses device builds, databases, and MDM configurations to surface weak policies, misconfigurations, and vulnerabilities that could lead to unauthorised access or data leakage.

    Tile Background

    Network Security Reviews

    Examines firewall rules, router and switch configurations, and network segmentation controls to identify gaps, unnecessary rules, and misconfigurations that could expose your network to attack.

    Tile Background

    VoIP Assessment

    Reviews your Voice over Internet Protocol (VoIP) services for vulnerabilities that could enable call interception, unauthorised access, or service disruption.

    Firewall Ruleset Review

    Reviews your firewall configuration in depth, identifying vulnerabilities that could put your business at risk. Using GuardNest, our consultants guide you through every remediation step, ensuring your firewalls are hardened and stay that way.

    Methodology

    We ensure testing has both depth and breadth by aligning with recognised methodologies such as CREST, OSSTMM, OWASP, and NIST. 

    This ensures a structured, consistent approach grounded in best practice and real-world threat intelligence.

    We follow a clear seven-step process designed to deliver rigorous testing, meaningful insight, and practical remediation guidance at every stage.

    We listen to your needs and develop a tailored project strategy, producing a scope that meets your unique requirements.  

    Where vulnerabilities are successfully exploited, our consultants assess their severity by determining which assets and networks can be accessed and what data may be exposed. Vulnerabilities are then ranked from low to critical within GuardNest.

    We scan and enumerate the defined targets to identify existing vulnerabilities. This includes listening for open ports, identifying running services, and developing an attack plan based on the scan results. 

    Our consultants assess how deeply they can access your systems using leading industry techniques, custom-built tools, and their first-hand experience. 

    If a consultant successfully exploits a vulnerability, they assess its severity. This involves determining which assets and networks can be accessed and how much information can be gathered. Your vulnerabilities are then ranked from low to critical in GuardNest.  

    We publish the findings in a report on GuardNest, organised by category and type, with remediation advice for each exploit and vulnerability. On request, we also arrange debrief calls to review identified risks in detail and discuss remediation.

    Your GuardNest licence includes continuous external infrastructure scanning to minimise risk between tests. We also offer a remediation check service, and every engagement includes a full consultative approach to ensure ongoing support even after the project is complete.
