SIEM consulting
A SIEM is only as good as the data in it and the people using it. We help you decide what to collect, how to structure it, what it costs, and how to move from one platform to another without losing coverage.
The problem this service solves
SIEM projects stall for predictable reasons. Teams ingest everything and are surprised by the bill, or ingest too little and cannot investigate. Logs arrive in inconsistent formats. Retention does not match investigation needs. Nobody owns the content.
We start from the questions you need to answer, such as investigating a compromised account, then work backward to the data, structure and cost.
What is in scope
-
Requirements and use cases
Translate investigation, detection and compliance needs into log requirements.
-
Architecture
Collection, storage tiers, retention, access control and high availability suited to your platform.
-
Log source onboarding
Prioritize sources, parse and normalize, and verify completeness.
-
Cost and volume management
Filter, tier and route data so expensive storage holds what needs it.
-
Content migration
Move and retest rules, dashboards and reports.
-
Integrations
Ticketing, SOAR, threat intelligence and case management.
-
Platform selection support
Compare options against your requirements, team skills and budget.
How the work runs
Plan
Define what you need.
-
1
Use-case workshop
Agree the top investigations and detections and what data they require.
-
2
Current-state review
Inventory sources, volumes, costs and gaps.
Build
Collect and structure data.
-
3
Pilot sources
Onboard the most valuable sources first, validating fields and completeness.
-
4
Normalization
Map to a consistent schema so rules work across sources.
Run
Hand over a working system.
-
5
Content and dashboards
Deliver initial detections and views.
-
6
Operational handover
Document onboarding procedures, ownership and review cadence.
What you receive
- Requirements and use-case catalog
- Reference architecture
- Log source priority list and onboarding runbooks
- Cost model and optimization plan
- Migration plan with content mapping
- Operations guide
Tooling and technique
We work with these platforms. Listing a platform does not imply a reseller or partner relationship.
Standards we map to
Mapping findings to a framework is not the same as certification against it.
Before we start
What we need from you
- Current SIEM inventory, volumes and bills
- List of important systems and their owners
- Retention and compliance requirements
What this service is not
- A managed SIEM or SOC service
- A licensing negotiation on your behalf
What changes afterwards
- Data volume and spend match the investigations that matter
- Logs are structured so rules work across sources
- Migration retains coverage
Questions people ask
Which SIEM should we choose?
It depends on your cloud footprint, team skills, data volume and budget. Organizations heavily in Microsoft 365 and Azure often find Sentinel convenient. Others standardize on Splunk or Elastic. We compare against your needs.
How do we lower SIEM cost?
Identify low-value, high-volume sources, filter fields you never use, tier older data to cheaper storage and avoid duplicate ingestion. Do it with an understanding of what investigations need.
