How do you secure systems when attackers are moving faster than your developers?

Derek Foster has spent his career inside that gap. 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. That shift matters now. Software velocity is accelerating, attackers are faster, and the cost of a breach averages over $4M.
