Jeffrey Shearer

Jeffrey Shearer approaches ICS cybersecurity from a direction few instructors can claim: forty years of designing, architecting, and implementing industrial and distributed control systems before ever stepping into a security classroom. As a SANS Certified Instructor and co-author of SANS ICS612: ICS Cybersecurity In-Depth and SANS ICS310: ICS Cybersecurity Foundations, he teaches students learning to protect the very kinds of systems he spent his career building, across automotive, food and beverage, mining, oil and gas, water and wastewater, chemicals, and pharmaceuticals. He currently owns Gray Man Cyber, where he works with clients across industrial sectors.
