SOC & SIEM Build, Detection Engineering, and Operations
Reduce noise, catch what matters, and respond faster. We design SIEM architectures, craft high‑signal detections, and operate or upskill your SOC with repeatable runbooks and metrics.
What we deliver
A modern SOC needs a reliable pipeline for telemetry, curated detections that map to attacker behavior, and crisp response playbooks. We build or tune your SIEM (self‑hosted or SaaS), reduce alert fatigue, and establish measurable performance.
Business outcomes
- Meaningful reduction in false positives
- Improved time‑to‑detect (MTTD) and time‑to‑respond (MTTR)
- Audit‑ready evidence (ISO 27001 / SOC 2)
Technical outcomes
- Detection-as-code repo with tests
- Runbooks with decision trees
- Dashboards and investigation workspaces
High‑value use cases
Account takeover
Impossible travel, MFA fatigue, token theft, session anomalies—detections + auto‑containment.
Ransomware
Early signals: suspicious encryption, shadow copy deletion, mass file ops, lateral movement.
Cloud abuse
Privilege escalation, key misuse, public data exposure, persistence through roles/apps.
Reference architecture
Ingest & normalization
Streaming collectors, schema-on-write/read, enrichment (GeoIP, asset, identity), and parsing with a shared taxonomy.
Storage & tiering
Hot vs. warm tiers, cost controls, retention aligned to compliance, and searchable archives.
Access & workspaces
Least‑privilege roles, scoped workspaces for SOC tiers, and temporary elevation for IR.
Automation
SOAR playbooks for enrichment, containment, and case management integration.
Detection engineering
Detection‑as‑code
Rules in version control with tests, peer review, tagging (tactic/technique/severity), and release notes.
Tuning & suppression
Field‑tested noise reduction: allowlists, device groups, maintenance windows, and adaptive thresholds.
Threat intel & ML
IOC mgmt with TTLs, behavior models for anomalies, and risk‑scored entity timelines.
Purple teaming
Adversary simulations to validate coverage and improve detections iteratively.
Log source coverage
| Domain | Examples | Why it matters |
|---|---|---|
| Identity | Entra/Okta, AD/LDAP, SSO, IAM | Account takeover & privilege escalation |
| Endpoint | EDR/AV, Sysmon, macOS/Linux audit | Malware, persistence, lateral movement |
| Network | Firewall, proxy, DNS, NTA | C2, exfiltration, recon patterns |
| Cloud | CloudTrail, Azure Activity, GCP Audit | IAM/key abuse, risky API activity |
| Apps | WAF, API gateway, auth services | Abuse of business logic and auth |
SOC workflows & runbooks
Triage
Contextual enrichment (asset, user, geo, threat intel), severity classification, and escalation thresholds.
Investigation
Entity timelines, correlated alerts, and pivoting through related telemetry.
Containment
Isolate hosts, disable users, revoke tokens/keys; case notes with approval trails.
Lessons
Update detections, refine runbooks, and adjust controls after PIRs.
Metrics & SLOs
Detection quality
- True‑positive rate, false‑positive rate, rule coverage
- Time to rule update after PIRs
Operational speed
- MTTD/MTTR, investigation cycle time
- Automation coverage and success rate
Methodology
1) Kickoff & design

3) Detections & workflows
High‑value rules, runbooks, and case management automation.
4) Operate & tune
Shadow operations, tuning sprints, and performance reviews.
5) Handover
Playbooks, training, and detection‑as‑code repo handoff.
Deliverables

FAQs
Can you work with our existing SIEM?
Yes—we tune what you have and add detections; we’re vendor‑agnostic.
How do you avoid alert fatigue?
Detection‑as‑code with testing, suppression logic, and PIR‑driven updates.
Do you support cloud & SaaS?
Absolutely—identity, cloud audit logs, and SaaS admin telemetry are first‑class.
Can you train our analysts?
Yes—playbook walkthroughs, case studies, and purple‑team drills.
