CardinalOps provides a SaaS platform for detection posture management that helps security operations centers (SOCs) optimize their existing SIEM, EDR, and XDR detection capabilities. The platform uses automation and MITRE ATT&CK framework integration to identify and address detection gaps, broken rules, and noisy alerts across security monitoring infrastructure. The platform enables organizations to map all detection rules to MITRE ATT&CK, measure detection coverage depth, identify broken or ineffective detection rules, and pinpoint root causes of alert noise. It supports Continuous Threat Exposure Management (CTEM) programs by validating detection posture and providing board-level reporting for auditors and leadership. The solution works across multiple SIEMs and security tools without requiring organizations to replace their existing security stack. CardinalOps serves customers across financial services, energy, manufacturing, consumer goods, professional services, and managed security service providers (MSSPs/MDRs). The company was founded by Michael Mumcuoglu and Yair Manor, veterans of Unit 8200, with backing from Battery Ventures, Glilot Capital, Viola Ventures, and IN Venture.
