About Federico

Network Security Engineer with 5+ years of hands-on experience in enterprise cybersecurity, based in Zürich.

I have worked for major organisations including SIX Group — the Swiss financial market infrastructure — and SKY Italy, managing complex security environments across Palo Alto, Fortinet, Cisco ASA, and Checkpoint. I am experienced in SIEM threat detection with Splunk, privileged access management with CyberArk, VPN architecture (IPsec/IKEv1-v2), and firewall policy management at scale using the Tufin Suite.

I have led SWIFT security audits, coordinated incident response, and communicated risk findings directly to C-level stakeholders — bringing both technical depth and business awareness to every engagement.

Available for freelance contracts and project-based work in network security, firewall audits, SIEM implementation, and compliance preparation (ISO 27001, NIS2).

Languages: Italian (native), English (C1), Spanish (B1), German (A2).
