Agentic Index
Prophet Security vs Radiant Security (2026)
Prophet Security and Radiant Security are both purpose built autonomous SOC platforms sold through enterprise sales with no public rates, so the evaluation comes down to scope and architecture: Prophet includes threat hunting and detection tuning in the platform rather than as add ons and offers single tenant VPC deployment for data residency, with independent evaluations consistently ranking its investigation autonomy and explainability at the top of the lane, while Radiant pairs agentic triage with integrated log management and unlimited retention, positioning itself as a partial SIEM cost replacement. Prophet is the depth play; Radiant is the consolidation play.
