Pricing
PaidExabeam uses quote-based, volume-driven pricing based on data ingested per day (GB/day). There is no publicly posted list price \u2014 all contracts require direct engagement with Exabeam\u2019s sales team. A Forrester Total Economic Impact study commissioned by Exabeam modeled a composite New-Scale Fusion customer spending approximately $1.08 million over three years, including $75,000 in implementation fees and ~$147,000 in training and ongoing internal effort, with 245% ROI demonstrated in the study. New-Scale (cloud) pricing is based on ingestion volume and retention period. LogRhythm SIEM (on-premises) uses component-based licensing. Volume discounts apply for larger ingestion commitments. Contact Exabeam through exabeam.com for a personalized quote.
PaidMicrosoft Sentinel uses consumption-based pricing with two primary models: Pay-As-You-Go (PAYG): ~$2.46-$5.20/GB of data ingested (varies by region). Best for organizations with variable or unpredictable ingestion below 50 GB/day. Commitment Tiers: Fixed daily rates offering 31-52% savings vs PAYG. Starts at 100 GB/day ($123/day = ~$3,690/month, ~$1.23/GB effective). Scales to 50,000 GB/day with the highest discounts. You pay the tier rate even on days when ingestion falls below the commitment. Three log tiers for cost optimization: Analytics Logs (full rate, real-time detection), Basic Logs ($1.12/GB, limited KQL), and Auxiliary Logs ($0.19/GB for cold/archival data). Many Microsoft data sources (M365 Defender alerts, Azure AD Identity Protection, Defender for Cloud) ingest at no additional Sentinel charge. Copilot for Security is priced separately at ~$4/SCU/hour. Contact Microsoft at azure.microsoft.com/sentinel for enterprise pricing.

Cloud-native SIEM+SOAR on Azure — AI threat detection, KQL hunting, and native M365 integration
Exabeam

Exabeam Pros & Cons

Pros

  • UEBA pioneer — deepest behavioral analytics and dynamic risk scoring of any SIEM platform, including industry-first Agent Behavior Analytics for AI agents
  • Exabeam Nova AI agents cut investigation times by over 50% with autonomous TDIR automation
  • Smart Timelines eliminate manual correlation — reconstructs complete attack story automatically from raw log events
  • Dual deployment — cloud-native New-Scale Fusion + on-premises LogRhythm SIEM gives flexibility no other combined SIEM vendor offers
  • Gartner Magic Quadrant Leader for SIEM (2025) — consistent analyst recognition
  • 3,000+ enterprise customers including financial services, healthcare, and government — proven at regulated industry scale
  • July 2026 Anthropic Claude observability — most forward-looking AI agent security monitoring in the SIEM market

Cons

  • Quote-based pricing with no public list price — evaluation requires sales engagement; Forrester composite customer spent $1.08M over 3 years
  • Still integrating LogRhythm merger (2024) with new CEO (Oct 2025) — product roadmap consolidation ongoing
  • Smaller ecosystem than Splunk’s 2,800+ Splunkbase apps — fewer third-party community detection packs
  • ~875 employees is smaller than Splunk or Microsoft — less enterprise-scale support capacity
  • KQL/SPL migration burden for organizations coming from Splunk — different query language and workflow retraining required
Microsoft Sentinel

Microsoft Sentinel Pros & Cons

Pros

  • 50-60% lower cost than Splunk Enterprise Security at equivalent ingestion volumes — significant TCO advantage
  • Zero infrastructure management — cloud-native SaaS SIEM with elastic scaling and no hardware or patching
  • Native SOAR included free — 200+ Logic Apps playbooks at no additional license, unlike Splunk SOAR
  • Native Defender XDR integration — M365, Azure AD, and Defender alerts ingest with zero connector overhead
  • Three-tier log pricing (Analytics/Basic/Auxiliary) — cost-optimize ingestion by routing cold data cheaply
  • 8,500+ Microsoft security experts — continuously updated threat intelligence and detection content
  • M365 E5 benefit — 5 MB/user/day free Sentinel data allowance for M365 E5 subscribers

Cons

  • Cloud-only (Azure) — no on-premises deployment option, unsuitable for air-gapped or strict data residency environments
  • KQL requires specialized training — different from Splunk’s SPL and SQL, creating skill gap for analysts switching platforms
  • Copilot for Security is consumption-priced separately — heavy GenAI SOC use adds $4/SCU/hour on top of Sentinel costs
  • Smaller third-party app ecosystem than Splunk’s 2,800+ Splunkbase apps — fewer community detection packs
  • Commitment tier billing is inflexible — paying the committed daily rate even on low-ingestion days with no refund
