# SIEM & Detection Engineering

> Build detections that fire on real threats, not noise.

A SIEM is only as good as its detections. We design, deploy and tune SIEM/XDR platforms, engineer high-fidelity detection rules mapped to MITRE ATT&CK, and cut alert fatigue so your team focuses on what matters.

## Outcomes

- SIEM/XDR architecture and deployment
- Log source onboarding and normalization
- ATT&CK-mapped detection content
- Alert tuning and use-case management

## Process

01. **Assess** - Review log sources, use cases and gaps.
02. **Engineer** - Build and map detections to ATT&CK.
03. **Tune** - Reduce false positives and prioritize.
04. **Operate** - Hand over or run it as a managed service.

## Deliverables

- SIEM/XDR deployment
- Detection rule library
- Use-case catalogue
- Tuning documentation

## Standards

MITRE ATT&CK, NIST CSF, Sigma


## Overview

A SIEM platform is often the most expensive component of a security stack, yet many organizations get little value from it due to incomplete log sources, excessive noise, and outdated detection rules. True threat visibility requires a custom-engineered SIEM aligned to your unique environment.

Our SIEM and detection engineering services design, deploy, and optimize SIEM platforms (such as Splunk, Sentinel, or ELK). We onboard critical log sources, build normalized data models, write high-fidelity detection rules mapped to MITRE ATT&CK, and aggressively tune out false positives to combat alert fatigue.


## What we cover

### SIEM Architecture & Design
Sizing, design, and deployment of cloud-native or hybrid SIEM architectures.

### Log Source Onboarding
Connecting telemetry from firewalls, identity providers, endpoints, and cloud logs.

### Data Normalization & Parser tuning
Writing custom parsers and mappings to align log sources with standard data models.

### Detection Rule Engineering
Writing custom SQL, KQL, or Splunk SPL rules targeting specific attacker techniques.

### Alert Tuning & De-noising
Analyzing alert logs to identify and filter out benign system activity and noise.

### SOAR Playbook Development
Automating initial triage and containment actions using custom API playbooks.


## FAQ

**Which SIEM platforms?**
We work across major SIEM/XDR platforms and can recommend one based on your scale, budget and data sources.
