Summary
🤩
Rockstar🎓
Top SchoolAlfredo Cardigliano is a Principal Engineer with over 15 years of experience designing high-performance network monitoring and packet-processing systems, currently leading development at ntop from his base in southern Italy. He combines deep kernel and driver-level expertise with practical user-space engineering to build passive and inline packet processing solutions for commodity hardware, tackling traffic classification, packet recording and DDoS mitigation. His open-source contributions to projects like nDPI and Suricata include zero-copy packet capture optimizations, PF_RING enhancements and new back-end APIs—work that improves real-world IDS/NDPI throughput and interoperability. Fluent in multiple programming languages and versed in concurrent, multiprocessor architectures, he blends low-level performance tuning with system integration and operational robustness. An often-overlooked strength is his track record of applying kernel hacking techniques to make mainstream network security tools scale on inexpensive hardware.
