About Me

Karol Budzyn / trashpanda-sec

OT Security · Cyber-Physical Systems · Aspiring Cryptographic Architect · Warsaw, PL

Part-time student at Warsaw University of Technology (ARICS), specialising in the security of Critical Infrastructure and Operational Technology (OT). I bridge the gap between high-level software integrations and low-level industrial hardware.

Currently focused on Cryptographic Agility and the transition to Post-Quantum standards in both government and industrial data environments.

From PLC commissioning in explosive atmospheres to secure government middleware — I build systems where failure is not an option.
