IT audit and recommendations: securing and optimizing your information system
In a world where information systems have become the cornerstone of corporate performance and security, having a clear and reliable view of your IT environment has become essential. Aging infrastructures, increasingly complex networks, uncontrolled applications and risks linked to the cloud or cybersecurity can make an organization permanently vulnerable.

Audit & Recommendations FAQ
Why carry out a full IT audit?
A comprehensive audit is the first step in regaining control of your information system. It identifies technical weaknesses, security risks, operational inefficiencies and unnecessary expenditure. For example, an infrastructure audit may reveal oversized servers or unused software licenses. A cybersecurity audit may reveal undetected vulnerabilities (inactive accounts, open ports, obsolete configurations). By carrying out an audit, you can anticipate breakdowns, reduce hidden costs and improve business continuity. It's also an essential lever for reinforcing regulatory compliance and reassuring your partners.
How often should an IT audit be carried out?
The frequency depends on how critical your business is, and how fast your IS is evolving. Companies operating in sensitive sectors (healthcare, finance, public authorities) should carry out a global audit every 12 to 18 months. For other structures, a periodicity of 24 to 36 months is sufficient. IT Systèmes also recommends more frequent targeted audits (cybersecurity, cloud, RGPD compliance) to keep pace with changes in threats and usage. These regular audits guarantee continuous improvement and better risk control.
How long does a full audit take?
The average duration of an audit varies between 3 and 8 weeks, depending on the scope. An SME with 50 users and a simple cloud environment can be audited in 2 weeks, while a multi-site group with several data centers will require up to 10 weeks. These timescales include interviews, data collection, testing, analysis and reporting. IT Systèmes plans its interventions to minimize the impact on operational activities and guarantee service availability throughout the mission.
What deliverables does IT Systèmes provide after an audit?
We submit a complete report structured into four sections:
- Detailed technical diagnostics with mapping of network, servers and applications.
- A safety and conformity assessment report
- An analysis of IS performance and resilience.
- A prioritized, costed and scheduled plan of recommendations.
Each report is accompanied by an executive summary designed to facilitate strategic decision-making.
Does the audit have an impact on production?
No. Our audits are designed to be totally transparent. The collection tools used are non-intrusive and comply with good security practices. Analyses are performed in read-only mode, with no system modifications. The rare tests requiring interaction are scheduled outside production hours, to avoid any disruption. This approach guarantees the reliability of the data collected, while preserving the stability of your environments.
Does the audit include cybersecurity and RGPD?
Yes, systematically. IT Systèmes includes a cybersecurity and compliance component in every audit. This includes assessing password policies, administrator access, identity management, personal data protection and backup management. We also analyze your level of RGPD compliance and propose concrete actions to strengthen data protection. This aspect is particularly crucial for companies exposed to external audits or regulatory obligations.
What concrete benefits can you expect from an audit?
A well-executed audit generates immediate and lasting benefits:
- Reduce operating costs (up to 30%) by eliminating redundancies and rationalizing licenses.
- Reduce the risk of breakdowns and improve service availability.
- Enhanced security and legal compliance.
- Productivity gains for IT teams thanks to better visibility and clear prioritization of actions.
- Enhance your company's image with partners and customers thanks to a controlled, secure information system.
What's the difference between an audit and a strategic study?
The audit is a detailed snapshot of the present, identifying strengths, weaknesses and risks. The strategic study, on the other hand, is a projection into the future, defining a roadmap for medium- and long-term development. In other words, an audit answers the question "Where are we now?", while a strategic study answers the question "Where are we going and how? At IT Systèmes, the two approaches are complementary: the audit prepares the technical foundations, while the strategic study structures the overall vision.
Can IT Systèmes help you implement these recommendations?
Absolutely. We provide complete post-audit follow-up: assistance with implementation, prioritization of projects, management of service providers, reporting and monitoring of gains achieved. We can also act as outsourced CIO or CISO to ensure the continuity and consistency of the improvement plan. This approach ensures that the results of the audit do not remain theoretical, but are translated into concrete, measurable improvements.
