Summary
Cribl 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-engineering platform that maps 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, then recommends or generates new detections to close them. It runs as a connected service, pulling rules and logs from a customer's SIEM and EDR via native API connections rather than requiring agents on endpoints. It's 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 a SIEM and EDR stack but lack a reliable way to track what those tools actually detect, using AI-assisted workflows and a catalog of over 8,000 curated rules to keep coverage current as infrastructure and threats change. It sits in the detection-engineering and telemetry-pipeline space rather than replacing the SIEM itself, and has been under development since 2018.
How Cribl CardinalOps helps
Which MITRE ATT&CK techniques have no detection coverage in my SIEM and EDR today?
maps existing rules from both tools against ATT&CK and produces a unified coverage score, showing which techniques have no supporting rule at all
Which of my existing detection rules are broken or silently failing?
runs rule validators against each rule to identify root causes of failure, such as changes to logs or schemas that broke the underlying logic
Which rules are generating so many false positives that analysts are drowning in noise?
runs statistical impact analysis on alert volumes per rule and flags the noisy ones so they can be tuned or retired
Where are the gaps a specific adversary or campaign would exploit that my current rules miss?
extracts atomic TTPs from threat intelligence about a named APT or campaign and checks them against current coverage, then generates new rules in the SIEM's native syntax or EDR's IOA format to close what's missing
Is my detection coverage keeping pace as my infrastructure and rule set change over time?
tracks rule health and coverage scores continuously across connected SIEM and EDR tenants, so drift shows up as a change in the baseline rather than going unnoticed
Which new rules should I add next, and can I trust them before deploying?
pulls candidates from a catalog of over 8,000 curated detection rules matched to identified gaps, and supports pushing them through existing CI/CD workflows before they reach production

Each offering on the pricing page links to its own page of plans, read at its latest capture.
Plan relaunches
Plans, prices and descriptions are quoted from the vendor's own pricing page as we read it on each date. A plan missing from a later reading is shown as no longer listed on the page — a statement about the page, not the product. Readings that failed to show any plans are left out rather than read as a change.
