// OUR SERVICES

Everything to help you secure both your present and your future.

DUE DILLIGENCE

Securing your growth

During an acquisition, a merger or a major scale-up phase, technological risk often remains your biggest unknown.

To avoid investing in a ‘black box’ concealing crippling technical debt or an architecture incapable of handling the load, we objectively assess the robustness and potential of the asset.

This enables you to make strategic decisions and determine value based on proven technological facts.
  • Objective audit of technical debt
  • Scalability test
  • Team Resilience Assessment

CYBERSECURITY

Securing your platform

A security breach is no longer just an IT incident. It is a direct threat to your reputation, your customers’ trust and the continuity of your operations.

To help you protect your infrastructure, applications and deployment pipelines (CI/CD) from vulnerabilities, we perform a comprehensive assessment of your defences.

You’ll receive a practical roadmap to shield your IT system without hindering your developers’ speed.

  • Business impact prioritisation
  • Compliance validation

Get full control back over your technology budgets by paying only for the resources that create real value for your business.

Frequently asked questions.

Why and how to run an IT audit?

An audit is a thorough review of your organisation’s resources, practices and posture across various areas: security, compliance, architecture, performance, cost management, software development, etc.

A well-conducted audit will provide you with a clear picture of the current situation, enabling you to identify vulnerabilities and shortcomings, as well as the actions required to improve your organisation’s posture in the area being audited.

You will be able to rectify these issues and also ensure that your systems comply with current standards and regulations. You can therefore choose to audit your infrastructure in full or in part.

Auditing your systems regularly should be at the heart of your IT asset management (ITAM) strategy. Once you are fully aware of your situation, you will be able to:

  • Develop better policies

     

  • Improve your teams’ performance

     

  • Set up an effective maintenance system

     

  • Restructure your costs

     

  • Ensure compliance with the GDPR and other applicable standards.

What are the different stages of an IT audit?
Whether you decide to perform the audit yourself or use a specialist firm, there are theoretically four stages required to carry out an IT audit properly:
  • Planning and preparation
  • Execution and collection of evidence
  • Analysis and assessment
  • Drafting and submission of the audit report
  • Follow-up
Upon completion, you will be provided with a clear roadmap setting out the priority actions to be taken. The follow-up phase serves to verify that the vulnerabilities have been rectified and that the necessary improvements have indeed been made.
How is the reporting structured?
We adapt to the way you work. Our standard delivery includes a strategic summary document (Executive Summary) and a presentation workshop.

On the technical side, we can even export the action plan directly as tickets into your project management tools (Jira, Notion, Trello, etc.) so that your teams can start working on it the very same day.
Do you provide one-off or long-term support?
Both, depending on your specific needs. Due diligence or an architecture audit are, by their very nature, one-off, intensive exercises designed to provide you with a clear snapshot at a given point in time.

However, for areas such as FinOps or cybersecurity, we focus on establishing long-term governance.

Following the initial action plan, we remain by your side (for example, through our quarterly follow-ups) to ensure that best practices become a permanent part of your teams’ day-to-day work.
