SIEM-as-a-Service
Azure Cloud Architecture
SIEM-as-a-Service Architecture is a SIEM solution powered by Elastic SIEM to perform the security Analysis and Monitoring against the advanced cyber security threats in a highly scalable and robust deployment hosted on Azure Cloud.
Solution is a centralised threat detection and investigation across Azure and hybrid estates. Elastic Agent (Fleet-managed) covers endpoints and workloads; Azure Activity Logs, Entra ID, and Defender arrive via Event Hub; third-party sources land through Agents/Logstash. Everything is normalised to ECS at ingest, so detection rules correlate across sources and analysts hunt from a single timeline.
What that demands: Fast search over recent data, cheap long retention for compliance and back-in-time hunts, and secure analyst access.
The deployment: The Stack runs self-managed on Azure VMs across Availability Zones; hot/warm data nodes on premium SSD handle live detection and search, with dedicated master and Kibana nodes for stability.
Retention: ILM ages data hot → warm → frozen → delete. The frozen tier sits on Azure Blob Storage via searchable snapshots, keeping 12+ months fully queryable at object-store cost, with no rehydration before a hunt.
Access: Kibana is fronted by an Azure Load Balancer with health probes. Data nodes stay in private subnets behind NSGs, TLS end-to-end.
