Dune Security is replacing legacy phishing simulations and security awareness training tools with a unified, automated User Adaptive Risk Management platform. It delivers User Adaptive Testing, Training, and Security to reduce administrative burden and mitigate risk. Unlike one-size-fits-all SAT models, Dune tailors security measures to each individual using intrinsic data (role, tenure), behavioral insights (red team testing), and analytics from a broad range of integrations (IDAM, EDR, DLP). Dune leverages the industry's most comprehensive risk scoring system to holistically assess individual risk, enabling automated, targeted remediation for high-risk users while allowing low-risk users to stay productive. This data-driven approach enhances security efficacy, streamlines operations, and strengthens overall organizational resilience.
