What happens when cyber threats hit critical infrastructure?

In this episode of the Bites and Bytes Podcast, host Kristin Demoranville sits down with Tom Sego, a cybersecurity leader with a fascinating background from chemical engineering to Apple to professional poker, now focused on making security simpler and more effective for critical infrastructure as CEO at Blastwave.

Cyber risks in critical industries are real, but so are the solutions. Kristin and Tom discuss why current security models create more problems than they solve, how the human element is often overlooked, and what needs to change to make security actually work for the people keeping our systems running.

🔎 In this episode, we unpack:

✅ How cyber threats can disrupt production & cold storage 🚜❄️
✅ Why critical infrastructure sectors struggle with cybersecurity adoption 🛑
✅ The AI-powered cyber threats targeting supply chains 🤖💥
✅ The human side of security—trust, simplicity, and keeping people safe 🛡️
✅ Why passwords are outdated and cause more harm than good
✅ How security teams can build trust instead of friction
✅ And yes… we also talk about wine, food obsessions, and French pastries 🍷🥐

Whether you’re in OT, security, or just sick of cybersecurity being unnecessarily complicated, this episode is packed with insights, humor, and real solutions.
