Cribl, which sells a data platform for collecting, routing and storing machine telemetry, said on 19 August 2026 that it had acquired technology assets from Radiant Security. The purchase covered the intellectual property behind Radiant's AI-native security operations center (SOC) product, software that triages, investigates and resolves security alerts without a human analyst working through each one.
Neither company disclosed financial terms. Cribl described the deal as a purchase of technology assets and IP, not an acquisition of Radiant Security as a company, and its announcement did not say how many Radiant employees, if any, would move to Cribl.
Cribl said it would adapt the software to run as an application on top of its own telemetry platform, so that the AI works against data Cribl's customers already collect and route through it. The company said it would share more about additions to the platform at its CriblCon conference on 28 September 2026.
What Radiant Security built
Radiant Security, based in San Francisco, pitched its product as an AI co-pilot for security operations teams. According to SecurityWeek's coverage of its 2023 funding round, the software automated alert triage, incident investigation, containment and remediation, as well as escalation and approval workflows. The company was led by a team of former Imperva and Exabeam executives.
The approach Cribl highlighted is that Radiant's system does not depend only on prebuilt playbooks. SiliconANGLE reported that it generates triage logic for each incoming alert and then runs the investigation directly against telemetry data where that data is stored. Cribl said combining this with its platform should reduce false positives and shorten the time it takes to detect threats.
The asset structure leaves open questions. D3 Security, a competitor in security automation, noted in a blog post that the announcement did not explain what happens to Radiant's standalone platform, its existing customer contracts and support commitments, or the more than 120 connectors Radiant listed publicly.
“Too much of the $121 billion security market is trapped in data silos, giving security teams incomplete information.”
Why Cribl is buying
Cribl's core business is moving and shaping logs, metrics and other telemetry between the tools that use them, a role that sits underneath security information and event management (SIEM) systems and observability products. The company says about half of the Fortune 100 use its platform.
Co-founder and chief executive Clint Sharp framed the deal around fragmented security data. In the announcement he said that too much of the security market, which Cribl sized at $121 billion, was trapped in data silos and left security teams with incomplete information, and that pairing AI SOC technology with an open telemetry platform was meant to end that pattern.
Andrew Braunberg, a principal analyst at research firm Omdia, said in the release that Cribl's approach centered on turning raw telemetry into a common foundation for AI-driven applications, with AI SOC, threat detection and observability layered on top so organizations could customize their security stacks.
The funding behind Radiant
Radiant Security announced a $15 million Series A in November 2023. Next47 led the round, and earlier investors Lightspeed Venture Partners, Acrew Capital, Uncorrelated Ventures and Jibe Ventures also put in more money. At the time, chief executive and co-founder Shahar Ben-Hador said the capital would go toward expanding the company's engineering and go-to-market teams.
No later round was reported in the sources reviewed for this article, and the price Cribl paid for the assets was not disclosed, so it is not possible to say how the outcome compares with the money Radiant raised.
Cribl's second security deal in two months
The Radiant purchase followed Cribl's acquisition of CardinalOps, an Israeli detection engineering startup, in July 2026. CardinalOps' software maps a customer's detection rules to the MITRE ATT&CK framework and points out where coverage is missing. Together the two deals give Cribl products for both writing detections and handling the alerts they produce.
Cribl itself was last valued at $3.5 billion in a funding round in August 2024, according to SiliconANGLE. The AI SOC category it is entering has drawn many startups selling automated alert triage to security teams that face more alerts than analysts can review.
