What is a network audit?

A network audit is a comprehensive assessment that maps and analyzes the current state of your IT network. Its goal is to uncover security gaps, misconfigurations, and areas where security, performance, or reliability can be improved. The audit reviews network devices, access management, logging, and data flows. This is especially important where high availability is a business requirement: the audit helps minimize downtime risk and supports business continuity. As a result, an enterprise network audit not only increases protection but also enables informed IT planning and long-term stability. Typical scope includes a firewall audit, a network security audit, and key NIS2 audit checks.

Audit Steps

1

Preparation and objectives

We gather requirements, understand the operating environment, and set the audit focus: security, performance, compliance, or a combination.

2

Data collection

Using automated tools and expert interviews we map assets, topology, configurations, traffic, and access rights.

3

Analysis and evaluation

We review network structure, security settings, firewall rules, logs, and firmware versions to identify outdated components, misconfigurations, and potential vulnerabilities.

4

Reporting and recommendations

We deliver a clear report describing the current state, risks, and concrete, prioritized recommendations for remediation or improvements. Related implementation: IT security solutions.

5

Consulting and support

Our experts help execute the action plan: full implementation, advisory, or follow-up as needed.

Why is it important?

A network audit plays a key role in modern IT strategy. It provides an end-to-end view of the infrastructure, surfaces issues and security risks, and informs future development with data-driven decisions. Since many vulnerabilities surface only during attacks or failures, an audit lets you identify and address weaknesses proactively.


A well-executed audit also supports regulatory compliance (e.g., GDPR, increasingly strict NIS2 compliance). Documented conformity not only covers legal aspects but strengthens trust with customers and partners.


Cost-efficiency matters, too. Audits often reveal underused resources, redundant capacity, or suboptimal device usage, enabling savings without compromising service quality. It also refreshes documentation that is critical for troubleshooting, planning, and integrating new systems.


In short, a network audit is not just a technical check, but a cornerstone of secure, well-governed IT operations. Organizations with regularly audited networks operate more reliably and transparently, a real competitive advantage in today’s digital landscape.

Frequently Asked Questions

How long does a network audit take?

Typically 2-10 business days depending on the environment, larger multi-site networks may require more time.


Will the audit disrupt business operations?

Unlikely. We plan critical steps with you, preferably outside business hours, to keep services safe.


What do I receive at the end of the audit?

A detailed report with a risk matrix, configuration and performance recommendations, and a prioritized action plan (quick wins and longer-term tasks).


Does the audit help with NIS2 compliance?

Yes. We cover logging, access management, backups, and incident response controls, highlighting any gaps.


How often should we repeat it?

Every 12-24 months, and after major infrastructure changes or significant incidents.


What are the next steps to remediate findings?

Remediation can be done by your team or with our help. Related service: firewall and network protection.
