What We Do

Radiant Security is a SecOps platform that enables the SOC to leverage the power of AI to streamline and automate analyst workflows. This dramatically boosts SOC analyst productivity, detects significantly more real attacks by deeply investigating every incident, and drastically reduces response times. Radiant’s AI-powered SOC co-pilot automates alert triage and incident investigation to provide unlimited capacity and to detect more real attacks. Incidents are escalated to analysts decision ready— with a complete root cause analysis and full incident scope: including affected users, hosts, applications, etc., and data stitching to follow attacks across data types. Radiant automatically generates a response plan to address each identified security issue, which can be executed manually by analysts, interactively with one-click response actions, or in a fully automated mode. The result is highly accurate triage and investigation that can scale indefinitely to handle any volume of alerts
