Pricing
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.
EnterpriseDarktrace does not publish public pricing. All contracts require direct sales engagement typically beginning with a Proof of Value (PoV) deployment period. Enterprise pricing is custom based on organization size, device count, selected platform modules (Network, Email, Cloud, Identity, OT, Endpoint, Secure AI), and deployment complexity. Reference pricing from verified buyer reports: approximately $30,000\u2013$100,000+/year for mid-size organizations, scaling to $500,000+/year for large enterprises with multi-module deployments. Contact Darktrace through darktrace.com to request a free PoV deployment and enterprise pricing discussion.

Summary
Cloud-native SIEM+SOAR on Azure — AI threat detection, KQL hunting, and native M365 integration
Self-Learning AI cybersecurity — detects zero-day and insider threats without signatures across 7 domains
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
Darktrace

Darktrace Pros & Cons

Pros

  • Self-Learning AI detects zero-day, insider, and AI-driven threats without signatures — uniquely catches novel threats rule-based systems miss
  • 7-domain coverage: Network, Email, Cloud, Identity, OT, Endpoint, Secure AI — broadest cross-domain protection in AI security
  • Cyber AI Analyst automates 92% of manual SOC investigation — biggest analyst burden reduction in the market
  • Gartner Magic Quadrant Leader for NDR 2026 — highest analyst recognition in network detection and response
  • Autonomous Response stops threats at machine speed without human approval — critical for ransomware and fast-moving attacks
  • OT/ICS coverage — one of few enterprise AI platforms with deep operational technology and critical infrastructure protection
  • $5.32B Thoma Bravo acquisition + $200M US investment in 2026 — strong financial backing and growth momentum

Cons

  • Taken private by Thoma Bravo ($5.32B, Oct 2024) — reduced public transparency vs publicly traded competitors
  • Third CEO in under 3 years (Ed Jennings, March 2026) — leadership instability raises questions
  • Initial 1-2 week learning period before Self-Learning AI baselines stabilize — higher false positives initially
  • No public pricing — enterprise contracts only, typically $30K–$100K+/yr for mid-size organizations
  • Less integrated AppSec/DevSecOps coverage vs CrowdStrike Falcon or Palo Alto XSIAM
