Cribl buys Radiant Security’s AI SOC tech in second security deal of 2026

Telemetry data firm Cribl Inc. has acquired AI security operations technology from startup Radiant Security Inc., marking its second security deal of 2026. The purchase encompasses the intellectual property behind software capable of automatically triaging, investigating, and resolving security alerts. Cribl plans to integrate this technology with its own telemetry platform, allowing the AI to analyze data already collected and routed through the platform.

Unlike traditional tools that rely on prebuilt playbooks, Radiant's software dynamically builds triage logic for each incoming alert and directly runs the investigation against the relevant telemetry data. Cribl CEO Clint Sharp highlighted the potential of combining AI SOC technology with Cribl's open telemetry platform, stating that it eliminates data silos and equips security teams with the intelligence needed as AI reshapes the operations landscape.

This acquisition is Cribl's second in 2026, following its purchase of Israeli detection engineering startup CardinalOps Ltd. in July, whose platform maps detection rules to the MITRE ATT&CK framework and flags coverage gaps. Analyst Andrew Braunberg of Omdia noted that Cribl's strategy focuses on transforming raw telemetry into a unified foundation for AI-driven applications, enabling customers to tailor their security stacks.

Radiant Security's platform automates alert triage and investigation, connecting to the security tools customers already use. Radiant was led by Next47 in a $15 million Series A round in November 2023, and Cribl, after its last funding round in August 2024, was valued at $3.5 billion. Cribl will showcase additional platform enhancements at its annual user conference, CriblCon, on September 28.
