Large Groups & Multinationals

Our program for large organizations assesses the information system and all IT environments to ensure consistent cybersecurity. We map IT infrastructures and systems to identify both cross-functional and local vulnerabilities. The approach aims to secure information systems at the group level while respecting regional contexts. We conduct IT security audits and risk analyses to prioritize risk management at the group level. Recommendations cover IT security policy, security policy, and shared operational rules. The framework defines the expected security level for each subsidiary and proposes harmonized security measures. We evaluate system security, network security, and the robustness of authentication mechanisms. Our architectural designs include encryption and cryptography to protect sensitive and confidential data. The program strengthens digital security against cyberattacks and cybercrime targeting multi-regional environments. We test resilience against hacking and attacks by hackers through exercises and operational audits. The proposed information security governance helps the CIO coordinate policies, roles, and steering committees to reduce IT risk. Our security measures include server hardening, network segmentation, EDR/antivirus, and privileged access control. We help formalize a security policy to protect critical information and assets. Deliverables include IT system maps, vulnerability matrices, and remediation plans prioritized based on risk analysis. The global SOC and multi-region monitoring are designed to detect security incidents and malicious behavior. We assess ANSSI/CNIL compliance and adapt policies to local regulations and DORA/NIS2 requirements. The plan integrates the security of cloud services, APIs, and connected devices used by subsidiaries. Our technical recommendations cover strong authentication, password management, MFA, and IAM security solutions. The framework aims to make systems secure and securable by limiting the attack surface against cyberattacks. We implement indicators to measure the level of security and the effectiveness of security measures over time. The strategy includes incident playbooks, crisis procedures, and centralized coordination of inter-business unit escalations. Our experts recommend encryption, cryptography, and data flow protection measures to ensure confidentiality. The goal is to standardize information systems security, reduce cybercrime, and protect confidential data.
