Computer and Network Security Pleasanton, California 51–200 employees Founded 2021 Privately Held

Radiant Security operates an AI SOC platform that ingests alerts from any security tool and uses machine learning to triage and automate response. The tech stack—React, Next.js, TypeScript frontend with RAG as the core adoption—reveals an LLM-first architecture centered on retrieval-augmented generation for alert contextualization. Active projects around agentic flows, LLM fine-tuning, and response automation, combined with pain points around cost-effective LLM deployment and scalable automation, show a company actively optimizing inference costs and expanding beyond predefined security playbooks into environment-agnostic automation.
