### 4. [Crimson7 Defensive Engineering](https://cybersectools.com/tools/crimson7-defensive-engineering)

Defensive Engineering is a professional service from Crimson7 that builds, validates, and optimizes detection rules for SOC teams. The service includes detection confirmation and validation to reduce false positives and improve alert fidelity in existing rule sets, detection-as-code development (KQL, Sigma, ARM templates) for uncovered attack techniques, response-as-code workflows delivered through Microsoft Logic Apps, and proactive threat hunting using KQL queries mapped to MITRE ATT&CK. Detection logic is developed from adversary research, breach analysis, malware reverse engineering, and internal red team findings, then validated against real attack execution before delivery. Rules are delivered via Git repositories with version control, documentation, false positive guidance, tuning recommendations, and MITRE ATT&CK mapping. The service is built around the Microsoft security stack (Sentinel, Defender XDR, Entra) but Sigma rules provide cross-platform compatibility with other SIEM/EDR platforms such as Splunk, Elastic, and CrowdStrike. Training sessions for SOC analysts covering rule logic, investigation procedures, and response recommendations are included with deliverables.</description> <parameter name="summary">Detection engineering service that builds, validates, and delivers SOC detection rules as code
