Shrink your attack surface by 40 % within 30 days—guaranteed. I’m a Palo Alto Networks–certified Security Engineer who designs Zero-Trust networks, tames Cortex XDR noise and stops breaches before they happen. Over the last three years I’ve deployed more than 50 firewalls (PA-220 through PA-5440) and two Prisma Access tenants for fintech, SaaS and industrial clients across LATAM, performing migrations from ASA, Checkpoint, Sophos and Fortinet to PAN-OS 11.1 with cut-over interruptions of less than 30 minutes and achieving mean-time-to-contain under 10 minutes through custom Cortex XDR playbooks. My credentials include PCNSE (2024), PCNSA, PSE-Strata, SASE and Cortex XDR. My five-step framework—GAP Zero-Trust design backed by clear ROI, flawless implementation (Panorama, GlobalProtect SSO, advanced threat prevention), hardening and optimization with ML-powered profiles, and a 30-day hyper-care program with full knowledge transfer—has helped customers cut critical incidents by 75 %. Typical deliverables include health-check reports, runbooks, draw.io diagrams and compliance dashboards.
