      Sajed Khan

      Founder & Chief Executive Officer, CattlemanOne

      CISO-level executive Inventor Author

      Sajed has spent twenty-five years at the center of cybersecurity and AI, leading security and technology across enterprise, government, healthcare, finance, and agency environments. He most recently led security due diligence on a $1B acquisition and is building out a global cybersecurity team as Director of Cybersecurity & Risk at CECO Environmental.

      His approach is the reason CattlemanOne exists: executives don't need more frameworks or dashboards — they need decisions they can stand behind. He translates complex security, vendor, and enterprise risk into concise, executive-ready calls, then builds the programs that deliver on them.

      He is a co-inventor on two U.S. AI patents in 3D medical image analysis, bridging cybersecurity and healthcare through privacy-preserving diagnostic systems. The first was issued as U.S. Patent No. 12,665,073; the second is in examination. He is also the author of Sarah and the Malware Fairy, a children's book that teaches online safety through story rather than fear, and CyberSecurity Metaverse.
