David-Alexandre Birkett

Consultant / Senior Project Manager in Infrastructure, Maintenance in Operational Condition (MA) and Information System Security, I support companies in managing critical projects, securing environments, and ensuring the reliability of IT infrastructures.

With over 12 years of experience, I work in complex contexts involving multi-site, multi-stakeholder environments with high stakes in availability, security, and compliance.

I assist CIOs, CISOs, and technical directors facing:

• Infrastructure security and hardening challenges

• Sensitive or high-pressure environments

• Poorly defined or risky multi-infrastructure projects

• Needs for structuring MA and IT operations

My areas of intervention notably cover:

- Infrastructure, network, and security project management

- Maintenance in Operational Condition (MA) and operations

- IS Security: hardening, CIS / ANSSI compliance, IAM / IGA

- Multi-stakeholder coordination and team management

- Implementation and monitoring of KPIs, reporting, and governance

- Facilitation of Steering Committees / Project Committees and business workshops

I have notably managed:

- IT security reinforcement programs (GPO, Intune, AD tiering, firewalls)

- Multi-site network deployments (FTTO, FON, SD-WAN, MPLS)

- Structuring projects directly with CISOs and IT directors

Results-oriented, I focus on environmental stability, risk management, and IT operations security.

Available for infrastructure management, MA, security, or CISO support missions.
