SIEM is the central component of a mature security system. It collects events from all sources and correlates them to detect threats. Two leaders: Microsoft Sentinel and Splunk Cloud.
Microsoft Sentinel
Cloud-native SIEM on Azure Log Analytics. Free M365 and Azure log ingestion, 200+ connectors, AI analytics, Defender XDR integration. Priced per GB ingested.
Splunk Cloud
20+ years of development. Powerful SPL query language, vast Splunkbase ecosystem, vendor-agnostic. Priced per GB or workload-based.
How SL Global Service solves this
SGS deploys Sentinel for Microsoft environments, Splunk for multi-vendor. Also managed SOC: analysts monitor alerts 24/7 and respond to incidents.
SIEM choice is for years. Start with a 30-day trial of both platforms.
“A SIEM without a qualified analyst team is just an expensive log collector. Invest in people as much as in technology.”
Anton Marrero, member of the Supervisory Board, Intecracy Group
