Buyer's guide
What is SIEM software?
SIEM, or security information and event management, software collects log and event data from across an environment, correlates it to spot threats, and raises alerts a security team can act on. Modern SIEM adds behavior analytics and response automation, so it detects account takeover and insider risk, not just known signatures.
What is the difference between SIEM and XDR?
SIEM ingests logs from any source (network, cloud, apps, and endpoints) and is the system of record for detection and compliance. XDR focuses on correlating telemetry across a vendor's own security tools for faster response. Many teams run both, and platforms like Microsoft Sentinel and CrowdStrike now blend SIEM and XDR in one product.
How to choose
- 1.If you run Microsoft 365 and Azure, Microsoft Sentinel gives cloud-native SIEM with free ingestion of many Microsoft logs and pay-as-you-go scaling.
- 2.If you need the deepest query power and have a large SOC, Splunk Enterprise Security leads on search and correlation, at a premium price.
- 3.If you already run CrowdStrike Falcon, its Next-Gen SIEM folds SIEM into the endpoint console with fast, flat-rate ingestion.
- 4.If cost predictability matters most, Google Security Operations and Elastic Security offer flat or volume pricing that avoids surprise ingest bills.
Frequently asked questions
What is the best SIEM software?
The best overall is Microsoft Sentinel, because it delivers cloud-native detection, built-in SOAR, and free ingestion of many Microsoft 365 and Azure logs, scaling pay-as-you-go without hardware. Splunk Enterprise Security follows for the deepest search and correlation, and CrowdStrike Falcon Next-Gen SIEM is strongest for teams already running CrowdStrike endpoints.
What is the best Splunk alternative?
For cloud-first teams, Microsoft Sentinel and Google Security Operations are the leading Splunk alternatives, both with pricing that avoids Splunk's ingest-volume cost spikes. Elastic Security is the strongest option for teams that want open, flexible search at lower data cost.
How much does SIEM software cost?
Cloud SIEM pricing is usually volume-based: Microsoft Sentinel starts around $2.30 to $5 per GB ingested, while flat-rate models like CrowdStrike Next-Gen SIEM and Google Security Operations price by data tier or user. Large Splunk Enterprise Security deployments commonly run into six figures a year for high-volume estates.
Is Microsoft Sentinel a full SIEM?
Yes, Microsoft Sentinel is a full cloud-native SIEM with over 300 data connectors, built-in analytics rules, UEBA, and SOAR playbooks through Logic Apps. Its main watch-out is ingestion cost at high volume, which is why teams tune what they send and use the free Microsoft-log allowance.
What is the best free or open-source SIEM?
Wazuh is the leading open-source SIEM and XDR, free to self-host with log analysis, threat detection, and compliance modules. Among commercial tools, Elastic Security has a free self-managed tier, though scaling and support move you to paid plans.

Honest disclosures
- Most candidates are US-based, and pricing models differ so much (per GB, per compute, per user, or flat) that direct cost comparison is approximate.
- Several enterprise vendors use quote-only pricing, so cost bands are estimates from published rates and reseller ranges.
- The ranking weights detection and correlation heavily, so log-management-first or budget tools score lower here even when they fit smaller teams well, which is why Wazuh sits as the wildcard.
