Why audit your security
What you gain from an IT security audit
Cybersecurity is no longer optional — 1 in 2 SMEs suffered a cyberattack in 2024. Preventive audit costs 20x less than a breach.
Reduced cyberattack risk
Ransomware, phishing, intrusion — fixed flaws mean avoided attacks. Every fix counts.
Data protection
Client, financial, HR data — your sensitive information is identified, classified and protected.
Security compliance
GDPR, ISO 27001, NIS2, LPM — a secured IS is also compliant with regulatory requirements.
Improved reliability
More stable systems, fewer outages, business continuity assured — security also improves performance.
Peace of mind for leadership
You know your IS is under control — no need to fear every suspicious email or external access.
Strengthened credibility
Clients, partners, insurers, investors — a solid security posture strengthens credibility and insurability.

What is an IT security audit?
An IT security audit is an in-depth analysis of systems, networks, applications and access to identify vulnerabilities, configuration flaws and cyberattack risks. It results in a detailed report and prioritised hardening plan.
What is the difference between a security audit and a pentest?
The security audit is a global risk analysis (configuration, policies, access, documentation). The pentest (penetration test) goes further: experts actively attempt to penetrate your systems to discover real exploitable vulnerabilities. Both are complementary and often combined.
Which businesses need a cybersecurity audit?
Any business that stores client data, uses online tools, has remote access or processes sensitive information. Healthcare, finance, industry and public sector are particularly exposed. 1 in 2 SMEs suffered a cyberattack in 2024 — an attack costs an average of €27,000 for a French SME.
How much does an IT security audit cost?
From €2,000 to €5,000 for a simple audit (micro-business), €5,000 to €15,000 for an advanced audit with technical testing and pentest, and €15,000 to €40,000+ for a full audit with deployment of hardening measures. A personalised quote is provided within 24h.
What is an outsourced CISO?
The outsourced CISO (Chief Information Security Officer) is a cybersecurity expert who manages your IT security part-time. They define your security policy, manage incidents and provide ongoing monitoring — without the cost of a full-time role.
