Niche OT cybersecurity skills reduce candidate pool despite mid-level experience requirement.
OT SIEM, ICS protocols, and industrial control knowledge make the role highly industry-specific and less transferable.
Mandatory 5+ years SIEM/OT experience, SIEM/SOAR skills, and relevant certifications create strict filters.
