This document summarizes the key findings of the Foundry Security Priorities Study conducted in 2021. The study surveyed 772 IT and security professionals to understand their top security priorities and projects for 2021 and beyond. It found that the top priorities were being prepared to respond to security incidents, improving data protection and security awareness training. Zero Trust and SOAR technologies had the highest percentage of respondents researching or piloting them. On average, security incidents took 5 weeks to detect, with non-malicious user error being the leading cause. Physical security responsibilities had increased for many respondents in the past three years.
