CardinalOps is a commercial SIEMSIEMSecurity information and event management, collecting logs from many systems and correlating events to find suspicious activity. Analysts use it to investigate alerts and incidents. detection-management platform that continuously audits an organization's existing SIEM and EDREDREndpoint detection and response, monitoring computers for suspicious behavior and providing investigation and response controls, such as isolating a device. rules against MITRE ATT&CKMITRE ATT&CKA publicly maintained knowledge base of adversary tactics and techniques observed in real attacks, maintained by MITRE. Cyber tools use it as a common taxonomy to classify, map, and communicate threat behavior. to find coverage gaps, broken rules, and noisy alerts. It runs as a connected service, pulling rule and log data from a customer's SIEM and EDR via native API connections rather than replacing either. It is built for SOCSOCA security operations center, the team or function that monitors threats, investigates alerts and coordinates incident response. Its work can be internal, outsourced or shared. teams and detection engineers who already run tools like Splunk or Microsoft Sentinel but lack a reliable way to see what those rules actually cover, and it layers AI-assisted workflows on top to turn threat intelligence into new rules and flag ones that need fixing. The vendor's own material frames this as a distinct discipline it calls detection engineering rather than a SIEM replacement, and CardinalOps has been operating in this space since 2018.
