Detections That Actually Work. Delivered as Code.
Defensive Engineering
We build, validate, and optimize detection rules that catch real adversary behavior, not generic indicators. Security-as-code, ready to deploy.
The Challenge
The Detection Gap
You have detection rules. But are they catching what matters? Coverage doesn't equal capability when rules are misconfigured, too narrow, or built from outdated intelligence.
Rules that never fire
Too narrow or misconfigured rules, high-volume alerts with low signal, and no coverage for sophisticated attack techniques that matter most.
False confidence
Detection logic that made sense when written, but threats have moved on. The result: false confidence in detection capabilities, until an incident proves otherwise.
Our Services
Defensive Engineering Services
From validation through development and optimization, detection engineering grounded in offensive research.
Detection Confirmation & Validation (DCV)
Make existing detections more effective. Reduce false positive rates, improve alert fidelity and context, and optimize query performance for your SIEM platform. Custom detection rules built specifically for your threat profile, aligned to your unique threat landscape.
Detection-as-Code (DaC)
Build detection capability for techniques you don't cover. KQL, Sigma, ARM templates, developed from offensive research, validated against real attack execution, delivered as code.
Response-as-Code (RaC)
A detection rule is only as good as the response it triggers. We build custom response workflows per client, not generic playbooks. Delivered as code through Microsoft Logic Apps, versioned, auditable, and maintainable.
Threat Hunting
Proactive hunting across your environment. KQL queries for Microsoft Sentinel and Defender, hunting runbooks with investigation guidance, and full MITRE ATT&CK mapping.
Our Difference
What Makes Our Detection Engineering Different
Your Outcomes
What You'll Gain
Validated Detection Coverage
Know exactly which adversary techniques your tools detect, and which they miss. MITRE ATT&CK mapping shows coverage progression over time.
Operational Detection Rules
Not recommendations, actual rules. KQL queries, Sigma rules, and response playbooks your SOC can deploy immediately.
Skilled Defensive Team
Your blue team learns by observing real attacks and participating in engineering. Knowledge transfer is built into the process.
FAQ
Defensive Engineering FAQs
We specialize in the Microsoft security stack (Sentinel, Defender XDR) but also work with Splunk, Elastic, CrowdStrike, and other platforms. Sigma rules provide cross-platform compatibility.
We validate every detection against real attack execution. If the rule doesn't fire reliably against the technique it's designed to detect, we don't deliver it.
Via Git repository, yours or ours. All rules are version-controlled with full documentation including MITRE ATT&CK mapping.
Detection Confirmation and Validation (DVC) focuses specifically on validating and improving your detection rules through controlled simulation. Purple team exercises are broader collaborative engagements that include DCV alongside offensive testing and knowledge transfer.
Defensive engineering benefits organizations at various maturity levels. For less mature teams, we focus on foundational detections. For advanced teams, we target sophisticated techniques and advanced analytics.
Each rule includes MITRE ATT&CK mapping, technical description, false positive guidance, tuning recommendations, investigation playbooks, and validation evidence showing the rule triggering against real attacks.
We execute real attack techniques in controlled environments and verify that detection rules fire correctly. We test for both true positives and false positive scenarios.
Absolutely. We audit existing rule sets, identify gaps, reduce false positives, and improve coverage. We provide detailed analysis of rule performance and recommendations for improvement.
Our detection development is informed by current threat intelligence, Advanced Persistent Threat (APTs) group tactics, techniques, and procedures (TTPs), our own internal vulnerability research as well as our own red team findings. Rules target real-world-informed attack campaigns.
Yes. We provide training sessions for your SOC analysts covering rule logic, investigation procedures, and response recommendations. Training materials are included with deliverables.
