In a digital landscape where 43% of organizations experienced a cyberattack in 2025, a corporate security audit becomes your best digital umbrella! A preventive approach is no longer optional — it’s an essential responsibility to ensure the continuity of your operations. At MS Solutions, we leverage our expertise to identify vulnerabilities and strengthen your defenses against these ever-evolving threats.
Why do an IT security audit?
IT security is a major issue for any organization. A security audit takes a snapshot of your company’s security posture at any given time. This is an action to take in prevention of any potential attack in order to identify how to strengthen your strategy to adequately protect yourself.
Here’s why a security audit is essential:
Identification of vulnerabilities: A security audit helps identify flaws and weak points in your IT infrastructure before they are exploited by cybercriminals.
Regulatory compliance: Organizations often must comply with specific data security standards and regulations. An audit helps you verify that you are meeting these legal and industry requirements.
Incident Prevention: By identifying potential risks, a security audit helps put preventative measures in place, reducing the likelihood of costly and disruptive security incidents.
Reputation protection: A data breach can seriously damage a company’s reputation. A security audit helps protect this reputation by strengthening defenses against cyber threats.
Resource Optimization: An audit helps ensure that security resources are used efficiently, allocating investments where they are most needed
- Protection of sensitive data: An audit helps identify vulnerabilities and protect confidential information against cyberattacks.
- Continuous improvement: Cybersecurity is a constantly evolving field. Regular auditing helps you stay up to date with new threats and technologies.
- Competitive advantage: A company with strong cybersecurity can stand out from its competitors and gain customer trust.
What type of organization is a security audit suitable for?
It is often misunderstood that only large companies or highly regulated industries need to worry about IT security. In reality, all organizations, regardless of their size or industry, are affected by cybersecurity.
Here’s why:
SMEs: Now prime targets for cybercriminals (75% of cyberattacks in France), these organizations are often seen as having weaker defenses. With 16% of small and medium-sized enterprises experiencing incidents in 2025, a security audit helps strengthen protection before it’s too late.
Regulated sectors: Companies in finance (63% exposure to cyberattacks), healthcare, or energy (67% exposure) must comply with strict standards set by executives and regulators.
Public organizations: Particularly targeted, with only 36% cyber maturity in the public sector, they need to protect critical information and ensure service continuity.
Construction companies: The most exposed sector, with 83% exposure to cyberattacks, must integrate security measures alongside new technologies to keep pace with evolving risks.
Startups and growing SMEs: Especially vulnerable, as 60% of SMEs hit by a serious attack close within six months. They must anticipate risks from the outset to avoid average costs of €14,720 per cyberattack.
What does a security audit consist of?
An IT security audit with MS Solutions is a comprehensive process designed to assess the security strength of your organization across different critical areas.
Organizational security: We check that your organization has solid governance governing information security, in particular through clearly defined policies, directives and procedures. We ensure that this governance is approved by senior management, communicated to all staff and respected by all employees. We also validate that incident and change management is consistent with industry best practices.
Public asset security: We ensure that your organization effectively controls its public assets, such as domain names, website and social media. We also verify that only authorized individuals can make changes to these critical assets.
External network security: We assess the protection of your security perimeter to ensure a robust defense against external threats. In addition, we validate that remote access and inter-site communications are properly secured to prevent any intrusion.
Physical security: We verify that physical access to your organization’s facilities is strictly controlled and secure. This includes protecting sensitive areas such as infrastructure, server rooms, and point-of-sale (POS) locations, as well as preventing unauthorized access to the network.
Internal Network Security: We assess the mechanisms in place to protect your organization’s internal assets, focusing on high-privilege account management, access review and network segmentation. We also ensure that an effective antivirus solution is deployed and monitored on all systems, and that vulnerability management, including system updates and software patches, is adequate.
Operational security: We verify that your systems offer a high level of robustness and disaster recovery. We ensure that backup software is in place, that regular backups are carried out according to your needs, and that this data is secure. We also validate that comprehensive restoration testing is performed and documented.
| Audited Domain | Key Security Controls |
|---|---|
| Organizational | Governance, policies, incident management |
| Public Assets | Domain control, websites, social media |
| External Network | Perimeter, remote access, secure communications |
| Physical | Access control, protection of sensitive areas |
| Internal Network | Privilege management, antivirus, patching |
| Operational | Backups, restoration tests, business continuity |
Security Audit: A Practical Example
A small distribution company recently called on our team for a full security audit. The results were surprising! The analysis revealed three major vulnerabilities: an outdated password system, unencrypted backups, and an unsegmented network. The potential impacts were alarming: risk of customer data exfiltration and operational paralysis. The company quickly implemented MFA (Multi-Factor Authentication).
Before / After:
Before: 60% of user accounts vulnerable to brute-force attacks
After: 95% reduction in successful intrusion attempts
Before: Breach detection took an average of 72 hours
After: Real-time alerts with team intervention in under 30 minutes
How to Conduct an IT Security Audit
Conducting a cybersecurity audit requires a methodical approach in several phases.
Step 1: Planning and Audit Objectives
It all starts with thorough preparation. The team clearly defines the scope to be assessed and the specific objectives. This step involves identifying stakeholders and selecting the appropriate methodologies – either white-box (full information) or black-box (simulated attack without prior knowledge).
Step 2: Implementation and Testing (Field Exercises)
Next comes the active testing phase, where specialists attempt to compromise the system in a controlled manner. Practical exercises may include phishing simulations or network penetration tests to uncover vulnerabilities invisible to theoretical analysis.
Step 3: Audit Results – Reports and Roadmap
The analysis produces a report that prioritizes vulnerabilities according to risk level and provides a personalized action plan. This roadmap clearly defines the responsibility of each stakeholder for implementing fixes – who must act, when, and how.
In short
Cybersecurity has become an absolute priority for all organizations in 2025. Faced with increasingly sophisticated threats, a comprehensive audit of your IT infrastructure is essential to identify vulnerabilities and strengthen your defenses.
At MS Solutions, we not only ensure optimal protection but also provide a rapid and effective response in the event of an incident.
