What is Radiant Security?

Radiant Security is an AI SOC platform that triages and investigates security alerts across sources including endpoint, identity, cloud, email, network, and SIEM, then escalates what it assesses as real threats to analysts with documented reasoning. The vendor states analysts can execute response actions from within the platform, and an integrated log management option stores data in the customer's own S3 bucket. It deploys as cloud-hosted SaaS and connects to existing tools through API-based integrations, which press coverage of its Series A described as deployable in minutes.

Best for: SOC teams that want automated triage and investigation layered over existing detection tools, with optional log management.
Pros
  • ✓ Press coverage of the Series A reported API-based deployment in minutes, with a customer escalating a real threat within two hours of installation (SiliconANGLE)
  • ✓ Vendor states every AI conclusion includes transparent reasoning and a full audit trail
  • ✓ Raised a $15M Series A led by Next47 with participation from Lightspeed, Acrew, and others in November 2023 (SiliconANGLE, SecurityWeek)
Things to check
  • • No public pricing; the vendor describes a flat-rate subscription but figures require a sales conversation
  • • Cloud-hosted SaaS delivery, so review data residency and log storage requirements
  • • Founded in 2021 with $15M in disclosed funding, so apply standard early-stage vendor diligence
