Radiant Security Raised $15 Million Led by Next47

Radiant Security raised $15 million in a Series A funding round, led by Next47, to expand its AI-enhanced security operations solutions. Participating investors include Lightspeed Venture Partners, Acrew Capital, Uncorrelated Ventures, Jibe Ventures, and General Advance. The new funding will be used to grow the team and drive technical innovation.

Radiant Security provides an advanced cybersecurity solution that leverages artificial intelligence for automated detection, triage, and comprehensive investigation of security threats. By integrating data across email, endpoints, networks, and identities, their system ensures that no aspect of an attack is overlooked. The platform's Impact Analysis feature digs deep into each malicious alert to ascertain its root cause and the full extent of the incident, spanning all affected users and systems.

Once a threat is identified, their platform expedites containment and remediation with dynamic, incident-specific response plans, enabling either automated or manual interventions for a rapid and effective resolution. The platform also streamlines the necessary escalation and approval processes, integrating with a company's existing protocols to efficiently authorize corrective actions. Post-incident, Radiant offers strategic recommendations to improve an organization's security resiliency, reducing the chances of recurring threats and strengthening the overall defense against future attacks.

The startup was founded in 2021 (then known as BlastRadius) by Shahar Ben Hador and Barry Shteiman.
