Architecture audits
Keep your infrastructure secure.
What is an architecture audit?
Architecture audits assess the design and security of your IT infrastructure to identify vulnerabilities and improve its resilience. They examine your choice of network protocols, segmentation, traffic flow management and how well they align with industry best practices.
Objectives
Our architecture audits surface gaps and areas for improvement along the following axes:
Infrastructure design
Network segmentation and isolation
Network flow analysis and optimization
Access management and admin rights
Compliance with standards and best practices
Backups and logging
The HELX approach
By reviewing your architecture documents and interviewing your teams, we identify where the architecture of your IT environment can be improved. This lets you anticipate risks and take a proactive stance on security. At the end of the audit, you receive tailored recommendations to strengthen the structure of your architecture, improve the security of data in transit and ensure effective access management.
Methodology
The architecture audit is built on a document review, enriched by interviews with key stakeholders. Technical analyses are also performed on specific network devices. Our audits follow the process below:
- 01
Information gathering
We collect the documents, architecture plans and network diagrams that will serve as the basis for the audit. We also identify with you the people to involve.
- 02
Architecture mapping
We analyze the network topology, identifying the key components (servers, devices, data flows) and spotting the vulnerable areas that could affect security, at both the network and software level.
- 03
Architecture security review
We check the security controls (firewalls, VPNs, access controls) and configurations (encryption, identity management, updates) to spot misconfigurations and vulnerabilities affecting system security.
- 04
Resilience analysis
We also assess the resilience of the architecture, its redundancy, its disaster recovery plan and its compliance with security standards (CIS, NIST, etc.) to ensure business continuity and regulatory compliance.
A bit of technical detail
Our architecture audits identify the security vulnerabilities tied to the design of your IT network. We look for the following in particular:
- Poor network segmentation
- Permissive firewall rules
- Missing encryption of sensitive data
- Weak or missing authentication mechanisms
- Logs not centralized
- Lack of redundancy
- Lack of isolation between zones
- Irregular updates
- Loose access rights management

Frequently asked questions
How does an architecture audit work?
A document review (diagrams, flow matrices), interviews with your teams, then analysis: segmentation, exposure, attack paths, single points of failure. The audit is entirely non-intrusive: expert analysis, no tooling run on your systems.
Our diagrams are out of date, is that a blocker?
No, it is actually common. The interviews fill the gaps, and the audit produces a corrected map of your environment, often the first useful deliverable of the engagement.
What do we get at the end?
An analysis of the structural risks in your architecture, recommendations prioritized by impact and effort, and a target architecture your teams can actually reach.
How long does it take and what budget should we plan for?
From €4,250 to €14,450 excl. VAT depending on the size of the organization, for a combined architecture and organizational audit, which takes one to three weeks. Small businesses, SMBs and non-profits get a 15% discount.
