CardinalOps

CardinalOps develops a SaaS platform for threat-informed detection engineering that connects to an organization's existing security analytics stack rather than replacing it. The platform plugs into SIEM and EDR APIs — including Splunk, Microsoft Sentinel, IBM QRadar, Google Chronicle SIEM and CrowdStrike — to inventory existing detection content, map it to MITRE ATT&CK, and produce rule-health and coverage scores across a unified, multi-tenant view. It identifies coverage gaps and generates new detection rules in the target tool's native query language or EDR format (for example CrowdStrike IOAs), drawing on a reference catalog the company describes as containing more than 8,000 curated detection rules and, in earlier materials, a proprietary knowledge graph of best-practice detection rules and queries.

Beyond gap closure, the product addresses broken and noisy rules using proprietary rule validators, root-cause identification and statistical analysis of resulting alert volumes, with the stated aim of reducing false positives and improving MTTD/MTTR. A threat-intelligence workflow ingests TI reports, feeds and TIP integrations, extracts atomic TTPs using AI, and generates rules tailored to specific APTs and campaigns. The company markets the platform under the labels "Agentic Detection Engineering" and the "CardinalOps Agentic Fleet," a set of purpose-built agents operating in AI-assisted, human-in-the-loop workflows, and has also positioned it as detection posture management, continuous threat exposure management (CTEM) and unified exposure management. Additional use cases include SIEM migration, identifying ingested log sources that do not contribute to coverage in order to reduce cost, managing detection posture across multiple SIEMs, and providing board-level metrics on threat readiness.

Founding story

Co-founders Michael Mumcuoglu (CEO) and Yair Manor (CTO) are veterans of the Israeli military intelligence Unit 8200, where they met and worked together on offensive and defensive cybersecurity. Mumcuoglu previously founded a network behavioral analytics company that was acquired by Palo Alto Networks, where he then spent three years working on the launch of the Cortex XDR platform. Manor co-founded IoT security company Netonomy, acquired by Allot, and earlier served as Director of R&D at data security company Zerto. The pair stated that they repeatedly observed environmental complexity and constant change as root causes of organizational security weakness, and that existing tools and processes did not address those underlying issues.

Business model

CardinalOps sells a cloud-based SaaS platform that connects to customers' existing SIEM, XDR and EDR deployments via native API connections, with CI/CD support for detection-as-code workflows. The company positions the offering as an overlay that optimizes prior tooling investments instead of requiring customers to replace their security stack.

Subscription-based SaaS for enterprise security teams and managed security providers; the sources do not disclose pricing.

Traction

The company launched in early 2021 and reported significant customer traction by March 2022 across manufacturing, financial services, hospitality, media, transportation and logistics, law firms and managed security services, including several very large enterprises and a leading MDR/MSSP. Company materials cite a reference catalog of more than 8,000 curated detection rules and a third-party ROI analysis by TAG Infosphere. Total capital raised reached $24 million as of the 2022 Series A, and the company was acquired by Cribl in July 2026.

Latest developments

Cribl announced on July 14, 2026 that it had acquired CardinalOps to extend its AI platform into security operations, citing goals of improving threat coverage, reducing security data costs and replacing legacy SIEM architectures. Preceding developments include the July 2025 launch of Cardinal AI for agentic exposure management, the introduction of the CardinalOps Agentic Fleet, automated delivery of new IOA rules for CrowdStrike Falcon EDR, and joint solution briefs with Cribl and Realm Security.
