About Youssef

Cybersecurity Engineer | PAM Wallix Bastion | SOC / SecOps | Network Security

Your challenges: protecting sensitive access, detecting threats, and securing your critical infrastructures. I work to strengthen your cybersecurity posture, make your systems reliable, and structure sustainable solutions.

Certified Cybersecurity Engineer (CEH, CCNA, and Wallix Administrator), with 5 years of experience, I support large companies on PAM (Wallix Bastion), SOC / SecOps, and network security topics. My role is to secure privileged access, improve incident detection, and ensure operational continuity, from implementation to operational readiness.

I have led Wallix Bastion deployment and administration projects, strengthened SOCs (ELK, TheHive, Cortex, MISP), and managed L2 incidents with Darktrace NDR, Varonis, Sophos EDR, and Microsoft Defender. I also work on vulnerability management (Nessus, ANSSI hardening) and the maintenance of network environments (Check Point, Fortinet, Palo Alto, F5 Big-IP). On the governance side, I support projects aligned with ISO 27001: Azure / M365 security, MFA, and EDR policies.

I bring a turnkey approach with concrete deliverables: secured systems, operational monitoring, controlled access, and usable documentation. Objective: a stable, maintainable, and compliant environment.

Technologies and methods: Wallix Bastion, Azure / M365, ELK, TheHive, Cortex, MISP, Nessus, Microsoft Defender, ISO 27001 standards, and ANSSI best practices.

Available in Paris or remotely, on a service or fixed-price basis. Need to structure your SOC, secure your access, or audit your environment? Let's chat via video, expect a response within 24 hours.
