Greg van der Gaast, cybersecurity leader and founder of Sequoia Consulting, shares why modern security keeps failing — and it’s not because attackers are getting smarter. Drawing from his path from teenage hacker to government witness to CISO, Greg reveals how weak IT foundations, broken processes, and poor data habits create the conditions for most breaches. He explains why security must be treated as a quality discipline, how unstructured data quietly multiplies risk, and how AI can finally help uncover the root causes that organizations often overlook.
