"Security is not a product, but a process" - Bruce Schneier
Hi there! I'm Rafa Ponce Vivancos, a cybersecurity professional based in Spain. I focus on building and securing modern systems, with an emphasis on practical defense, offensive security methodologies, and automation.

🔍 More About My Journey
I work across offensive and defensive security: assessing systems, identifying weaknesses, and implementing controls that reduce risk in real environments. I’m especially interested in the intersection of engineering and security—where automation, visibility, and secure-by-default design make the biggest difference.
I approach cybersecurity as a blend of technology, people, and process. That mindset guides how I build, test, monitor, and improve systems over time.
