How can a network infrastructure audit benefit my organization and what are common use cases?

A network infrastructure audit helps identify weaknesses, strengthens defenses, and enhances overall cybersecurity posture, safeguarding data and operational integrity. Common use cases include independent assurance after organic growth or infrastructure changes, and ensuring that configurations remain secure when IT suppliers or service providers are involved.

Does the audit disrupt network operations?

No. The audit is primarily a configuration and architecture review, and any active testing is agreed separately and planned carefully to avoid disruption.

Do you review firewall rules and how is it done?

Yes. We review rule sets for redundancy, shadowed rules, overly permissive access, insecure services, and legacy exceptions, and we provide specific remediation commands or configuration changes where applicable.

What devices and components are included in the audit scope?

Typical scope includes firewalls, switches, routers, VPN gateways, wireless infrastructure, network segmentation, and cloud network configurations, with findings focusing on misconfigurations, insecure defaults, overly permissive access, and architectural weaknesses.

What is a Network Infrastructure Audit and why is it important?

A Network Infrastructure Audit is a comprehensive and detailed examination of the entire technology framework that keeps your business operations running smoothly, including internet connections, servers, routers, firewalls, and all devices connected to them. The goal is to ensure everything is secured, functioning optimally, and free of vulnerabilities or open doors for cybercriminals, thereby strengthening your cybersecurity posture and safeguarding sensitive information and operational integrity.

Deep Technical Review of You
Network Security Architecture

A detailed technical audit of your network infrastructure — including firewalls, switches, routers, VPNs, wireless networks, and segmentation controls. Our engineers review device configurations, access control lists, routing policies, and security rules against hardening benchmarks and security best practices. Findings identify misconfigurations, insecure defaults, overly permissive access, and architectural weaknesses.

What is a Network Infrastructure Audit?

A Network Infrastructure Audit is a comprehensive and detailed examination of the entire technology framework that keeps your business operations running smoothly — including your internet connections, servers, routers, firewalls, and all the devices connected to them. The goal of conducting such an audit is quite straightforward yet crucial: to ensure that everything is set up securely, functioning optimally, and free of vulnerabilities or open doors for cybercriminals to exploit.

By conducting a thorough audit, businesses can identify potential weaknesses, strengthen their defences, and enhance their overall cybersecurity posture, thereby safeguarding their sensitive information and operational integrity against threats.

Why a Network Infrastructure Audit? Matters?

Networks are the highways attackers travel once inside an organisation. Misconfigured firewalls, overly permissive rules, and poorly segmented networks are among the most common contributors to significant breaches — and among the least frequently reviewed. Most network configurations accumulate years of legacy changes, default settings, and emergency rule additions that nobody has revisited. An independent technical audit finds the problems that the team responsible for the network are too close to see.

Common Use Cases

In the current digital landscape, it is essential to have a thorough use case for network infrastructure audits. These checks are vital in ensuring the ongoing security and resilience of both networks and systems against various threats and vulnerabilities.

Post-change validation

The process of thoroughly confirming that any new infrastructure changes have not introduced any unforeseen risks or vulnerabilities is essential for maintaining not just system integrity but also security. This careful verification is crucial in ensuring that all aspects of the system function correctly while safeguarding against potential threats that could compromise data or performance.

Segmentation review

Confirming that the various network zones are correctly and effectively isolated from one another is not only crucial for maintaining robust security but also essential for ensuring optimal functionality within the entire system. This isolation plays a vital role in preventing unauthorised access and potential threats while allowing each zone to operate independently, thus contributing to the overall stability and performance of the network infrastructure.

Cloud network architecture review

AWS, Azure, or GCP network security configuration is a critical and fundamental aspect of any effective cloud computing strategy. It involves not only setting up the necessary protocols and measures to protect sensitive data from unauthorised access and potential breaches, but also ensuring optimal performance and stability across the entire infrastructure. This configuration process requires a comprehensive approach that incorporates best practices, continuous monitoring, and regular updates to adapt to ever-evolving security threats. By doing so, organisations can maintain the integrity and availability of their applications and data, thereby enabling a secure and efficient cloud environment for all users.

Pre-penetration test

Validating configurations and settings thoroughly and meticulously before embarking on a formal penetration testing engagement is not just a minor detail; it is crucial to ensuring a successful and effective security assessment that can uncover potential vulnerabilities. A comprehensive review of these configurations and settings helps establish a solid foundation, allowing security professionals to identify gaps and weaknesses that could be exploited by malicious actors. Without this careful examination, the integrity of the entire testing process could be compromised, leading to inaccurate results and potentially leaving significant security issues unaddressed.

Firewall rule rationalisation

Rationalising firewall rules to adhere to established security best practices is essential for maintaining a robust defence against a wide array of potential threats. This systematic process ensures that our security measures are consistently effective and efficient at protecting our network. By regularly reviewing and updating our firewall rules, we can adapt to the ever-evolving landscape of cybersecurity threats, thus reinforcing our defences against both known vulnerabilities and emerging risks.
