Develop automation to manage security tools and integrate security standards in workflows (Infrastructure-as-Code, SDLC…).

Build and feed relevant KPIs, SLAs and reporting to meet business objectives.

Provide deep technological expertise, guidance, recommendations and standards on security at different layers (networks, systems, Cloud, endpoints, applications…) in a hybrid environment (Cloud/Onsite).
