À propos de Rafael

With over 15 years of experience in network and cybersecurity, I help companies secure, optimize, and scale their infrastructure with a hands-on, business-oriented approach.

I’ve worked with major players across banking, energy, manufacturing, telecom, transport, and healthcare, leading high-impact projects such as:

🔥 Firewall policy assessment and optimization (Skybox, Algosec)

🧱 Deployment and governance of enterprise firewalls (Palo Alto, Check Point, Juniper, F5 ASM)

🛡️ SIEM architecture and use case development (QRadar, Splunk) aligned with MITRE ATT&CK

🔐 Secure remote access solutions with MFA (Pulse Secure, Juniper SA, Vasco)

🌐 Full-stack network security for DMZs, VPNs, proxies, and WAFs

⚙️ Automation and monitoring (SolarWinds, Junos Space, Panorama)

I specialize in bridging the gap between technical solutions and business needs, ensuring that every security investment translates into measurable resilience and performance.

Whether you need to harden your infrastructure, respond to an incident, or design from scratch, I bring senior-level expertise with a flexible and collaborative mindset.
