From breaking video games with GameShark to securing large-scale fintech systems, he now builds what most teams still lack: a way to test, validate, and fix vulnerabilities continuously, not once a year.As Co-Founder and CTO of Best Defense, Derek is building an AI-driven cybersecurity platform that doesn’t just flag risks, it proves exploits and ships fixes directly into developer workflows.
