About me

Curious by nature, hands-on by choice.

Fabrizio Di Cesare
4+ years in enterprise security

My passion for cybersecurity started at the Ulisse Security Group at the University of Bologna. There I explored many areas of security — from web and network security to OSINT and reverse engineering — while taking part in dozens of Capture The Flag competitions. Those challenges gave me a hands-on mindset and a collaborative spirit that I still carry today.

After graduating I moved into the enterprise world at Vargroup and SeSa, growing from Cloud Engineer to IT Security Manager and securing the 50+ companies of the SeSa Group. Today I'm a vertical specialist on Cloudflare Application Security and Zero Trust: I design WAF policies, build ZTNA architectures and integrate Cloudflare with AWS, Azure, on-prem and Kubernetes platforms — automating everything I can along the way.

My goal is always the same: building practical, scalable security that protects businesses while keeping them agile.
