Information Systems Security and Cybersecurity: Professional Audits and Penetration Testing

Improving the security of an information system is not limited to installing software or automated tools. A true cybersecurity audit requires a structured, human-led approach tailored to your IT infrastructure, organizational processes, and physical environment.

Our security audits and penetration tests (pentests) identify exploitable vulnerabilities, assess their real-world impact, and help you prioritize actions to effectively reduce cyber risk.

Types of Cybersecurity Audits Conducted by Our Teams

Objective: Simulate a real-world attacker to measure the concrete impact of vulnerabilities.

Types of testing:

  • External (from the Internet)

  • Internal (from within your network)

  • Application (web, API, software)

  • Wi-Fi

  • Advanced scenarios (black-box, grey-box, white-box approaches, Red Team)

What you receive:

  • Proof of exploitation

  • Detailed attack paths

  • Prioritized findings based on real-world criticality

Objective: Detect vulnerabilities directly within applications and software.

We analyze:

  • Application vulnerabilities (OWASP: injections, XSS, deserialization, etc.)

  • Authentication and session management issues

  • Exposure of sensitive data

  • Business logic flaws

  • Implementation of security mechanisms

What you receive:

  • Demonstrated and contextualized vulnerabilities

  • Technical recommendations directly actionable by developers

  • Long-term improvement of security across the development lifecycle

Objective: Ensure that your systems and devices are configured securely.

We analyze:

  • Servers, operating systems, and virtualization

  • Network equipment, firewalls, VPNs, Wi-Fi

  • Active Directory, user accounts, and permissions

  • Internet-exposed services

  • Security and backup solutions

What you receive:

  • A list of misconfigurations that are actually exploitable

  • A prioritized remediation plan

  • Immediate reduction of your attack surface

Objective: Assess the overall robustness of your information system’s design.

We analyze:

  • Network segmentation and isolation

  • Sensitive flows and critical zones

  • System interdependencies

  • Resilience against internal compromise

  • Overall consistency of architectural choices

What you receive:

  • A clear map of structural risks

  • Recommendations for architectural improvements

  • A strategic overview of your security

Objective: Assess your organization’s maturity in managing cyber risks.

We analyze:

  • Security policies and internal procedures

  • Access and permissions management

  • Employee awareness and training

  • Incident and crisis management

  • Relationships with third-party providers

What you receive:

  • A clear maturity assessment

  • A practical improvement plan

  • Enhanced human and organizational resilience

Objective: Ensure that physical access cannot be used to bypass your IT security.

We analyze:

  • Access control to premises and server rooms

  • Access to workstations and internal network

  • Visitor and contractor management

  • Protection of sensitive equipment

What you receive:

  • Realistic intrusion scenarios

  • Simple and effective corrective measures

Objective: Assess your organization’s real resistance to user-targeted attacks.

Most successful cyberattacks today exploit human errors rather than technical flaws—clicking phishing emails, disclosing information, bypassing procedures, or social engineering intrusions.

We evaluate the strength of your human cybersecurity chain through controlled, educational exercises.

We conduct:

  • Realistic simulated phishing campaigns

  • Social engineering tests (calls, scenarios, fraudulent requests)

  • Assessment of employee reflexes

  • Measurement of adherence to internal procedures

  • Analysis of reactions to suspicious situations

What you receive:

  • Measurable indicators (click rates, credential entry, reporting)

  • Clear view of actual awareness levels

  • Identification of the most exposed employee groups

  • Targeted recommendations for awareness initiatives

  • Concrete support for training programs

This audit turns theoretical awareness into a measurable assessment of human cyber risk.

Note: Exercises are conducted in a controlled, supportive, and legally compliant environment, with a pedagogical, non-punitive approach.

Need a Recognized Regulatory Framework?

For certain organizations (government agencies, OIV/OSE, sensitive environments), a specific regulatory framework is required.

We can also perform PASSI-qualified audits, recognized by ANSSI and compliant with the requirements of RGS (General Security Framework) and LPM (Military Programming Law), when this level of rigor is needed.

This qualification complements our audit offerings, ensuring compliance in highly regulated or sensitive contexts.
