About us

Radiant Security is an autonomous MDR that automates security operations using machine learning and AI to triage and investigate incidents with a consistency, accuracy, and scale only achievable via software. Deployed in minutes via API, Radiant Security provides rapid time to value and immediately reduces analyst workloads by as much as 95%. The solution uses a knowledge graph that continually learns about an organization’s security and IT environment, then employs an autonomous decision-making engine to emulate the processes used by a seasoned security analyst. This software-based approach to security operations radically reduces the time and cost of performing security operations, thus freeing up resources for other initiatives.
