The 2021 SANS ICS/OT survey received 480 responses, an increase of 42% over the 2019 survey. Respondents represent a wide range of industry verticals, with additional respondents sub-classifying into 62 unique groups, from gaming to aviation to space systems and payment systems.
The survey represents a balanced view across the industry, capturing responses from those whose primary responsibilities emphasize ICS operations or IT/business enterprise. Most survey respondents spend most of their time focused on ICS cybersecurity. Half of those (50%) report that they spend 50% or more of their time on ICS cybersecurity, as opposed to the 2019 survey where 45% of respondents reported that they spend at least 50% of their time in OT/ICS cybersecurity. In 2021, more than 50% have roles that emphasize ICS operations, either solely or in conjunction with IT/business enterprise.
