SIEM Implementation and Migration

Detection use cases are selected from the threats that realistically apply to your sector and estate, so SIEM Implementation and Migration collects telemetry for a purpose instead of filling storage.

Deliverables:

• Use-case catalogue
• Threat model
• Priority detections

Severity definitions, triage procedures, escalation contacts and out-of-hours authority are documented and agreed, so the first real incident is not the first conversation about them.

Deliverables:

• Triage runbooks
• Escalation matrix
• Severity definitions

Identity, endpoint, email, network and cloud sources are connected with parsing validated and ingestion tiered by value, because cost control is part of the design in SOC, SIEM & Managed Detection.

Deliverables:

• Connected sources
• Parsing validation
• Ingestion cost model

A deliberate tuning period drives false positives down to a level a human can sustain, with every suppression documented and reviewed rather than quietly applied.

Deliverables:

• Tuning log
• False positive trend
• Suppression register

Analytics rules are mapped to MITRE ATT&CK techniques, written against your environment, and tested with simulated activity before they are trusted.

Deliverables:

• Analytics rules
• ATT&CK coverage map
• Simulation results

Monthly reporting on incidents, response times and coverage gaps is paired with quarterly threat hunting that feeds new detections back into SIEM Implementation and Migration.

Deliverables:

• Monthly reports
• Hunt findings
• New detections
