Building a Shield: How SOClogix Operationalizes Detection-as-Code for SMB Clients
Most MSSPs run static signatures that haven't changed since last quarter. SOClogix runs a version-controlled, peer-reviewed detection pipeline that ships new rules every week - and can prove it.
The Problem With Static Detections
Threat actors update their tools, techniques, and evasion methods constantly. The average MSSP updates their detection signatures quarterly - at best. In practice, many MSSPs are running detection logic that was written years ago and hasn't been reviewed since. When a new threat emerges, days or weeks pass before protection reaches client environments.
The deeper problem is opacity. When a client asks "why didn't you detect that?" most MSSPs cannot give a precise answer. They can't show you the detection rule that should have fired, explain why it didn't, or demonstrate that it's been fixed. The detection layer is a black box.
For clients pursuing CMMC Level 2 certification - or any compliance framework that requires documented, auditable security controls - this is a serious gap. "We have an EDR" is not an auditable detection program.
The SOClogix Detection-as-Code Approach
SOClogix built an internal detection engineering program around a single principle: every detection rule is code, and all code is version-controlled, reviewed, and tested before it runs in production.
The platform is built on LimaCharlie, a cloud-native security infrastructure platform that allows detection rules to be written as code, deployed through an API, and managed programmatically. Client endpoints run the SOClogix Shield Agent - a LimaCharlie-backed sensor that provides telemetry across process execution, file operations, network connections, and authentication events.
Detection Rules as Code (YAML/D&R Rules)
Every detection rule is written in LimaCharlie's D&R (Detect and Respond) rule format and stored in the internal shield-detections repository. Rules have a clear structure: what telemetry they match, what conditions trigger an alert, and what automated response actions (if any) follow. New rules are written in branches, not directly in production.
Peer Review Required - No Exceptions
No detection rule reaches a client environment without a second analyst review. Pull requests require at least one approved review before merge. Reviewers check: Is the logic correct? Will it produce false positives? Is the alert actionable? Is the respond block safe? This process catches logic errors before they create noise - or worse, miss real threats.
Automated Validation Pipeline
The CI/CD pipeline runs automated rule validation on every commit. Tests check that rule syntax is valid, that response blocks reference real actions, and that rules don't duplicate existing coverage. Test cases simulate known-bad telemetry to verify that new rules would have fired on past incidents. A rule doesn't pass CI without passing these checks.
Weekly Threat Intelligence Feed
The SOClogix threat intelligence team holds a weekly review of emerging TTPs from sources including CISA KEV updates, vendor threat reports, and intelligence from active IR engagements. New detection gaps identified in this review become tickets, are assigned to analysts, and tracked through the same review pipeline as any other rule. The result: the detection library improves every week, not every quarter.
What This Means for Clients
CMMC 2.0 Relevance
CMMC Level 2 (based on NIST SP 800-171) requires organizations to monitor system security on an ongoing basis and review audit logs for signs of unusual activity. For most small defense contractors, "we have an EDR" is their answer. For auditors, that's not sufficient - they want to see documented, maintained controls with evidence of ongoing review.
The Detection-as-Code pipeline provides that evidence natively: a git repository with dated commits, named authors, reviewed pull requests, and automated test results - for every detection rule in production. It's the difference between "we monitor for threats" and "here is the documented, reviewed, and tested mechanism by which we monitor for threats."
