Unveiling the True Cost of Microsoft Sentinel

February 15, 2024

Choosing a security solution isn't a solo act. It's a delicate dance between diverse stakeholders, each with their own priorities. Finance seeks budget-friendly options, IT emphasizes user-friendliness, Risk Management demands visibility, and Cybersecurity craves coverage, efficacy, and seamless integration. Finding the sweet spot where everyone wins is paramount.

According to a World Economic Forum study, security executives shouldn't be left operating in a silo. Empowering them goes beyond technical evaluations. It's about assessing future ramifications, including how pricing evolves and how the chosen solution impacts business outcomes. Yet, short-term costs often trump long-term security needs, leading to alluring "free" solutions that might not be truly cost-effective.

Microsoft Sentinel, a popular cloud-based SIEM platform, often enjoys the "free" association thanks to its Microsoft 365 connection. However, this perception is far from reality.

Unmasking the Hidden Costs of Microsoft Sentinel:

  • The "free" trial lasts a mere 31 days.
  • Sentinel isn't part of Microsoft 365; it requires an E5 license.
  • Only a limited set of logs are free; most incur additional charges.
  • Pricing hinges on data consumption, making budgeting a guessing game. Global data volume is projected to reach a staggering 175 zettabytes by 2025.
  • Full log storage isn't free, even within Azure. Retention periods come with a price tag.

Is Sentinel worth the cost? It's a nuanced answer.

  • For organizations heavily invested in the Microsoft ecosystem, Sentinel might fit the bill.
  • For others, particularly those with large data volumes or non-Microsoft environments, costs can spiral quickly.
  • Limiting data ingestion due to cost concerns creates visibility gaps, jeopardizing your security posture.

Log retention presents another layer of complexity.

  • Sentinel's free retention period is just 90 days. Compliance and forensics often necessitate longer periods, leading to additional charges.
  • Healthcare (HIPAA) and the EU (GDPR) mandate extended retention periods, further increasing costs.

Brace yourself for additional TCO bumps.

  • Microsoft Defender, Azure Logic Apps, and UEBA are not included in the base price.
  • Most SOC teams rely on these tools for a complete TDIR process, inflating costs further.

Data residency concerns loom large in the EU.

  • Microsoft can't guarantee geofencing for Sentinel, potentially violating Schrems II compliance.
  • EU-based organizations risk hefty fines for non-compliance.

Limited third-party integrations pose challenges.

  • Sentinel lacks native support for non-Microsoft products.
  • Analysts must learn ASIM to build custom parsers, adding complexity.
  • Gartner predicts 80% of enterprises will adopt unified access platforms by 2025, highlighting the need for broader integrations.

A complex taxonomy and KQL query language demand investment.

  • The absence of a single, source-agnostic taxonomy hampers workflows and increases MTTR.
  • Learning KQL adds a training burden for analysts, impacting resource allocation.

Choosing the right SIEM requires careful consideration. While Sentinel might seem like a budget-friendly option initially, hidden costs and limitations can make it less economical in the long run.

Exploring Alternatives: Logpoint Steps Up to the Plate

Logpoint offers a compelling alternative with several advantages:

  • Compliance with GDPR, Schrems II, and other regulations.
  • Predictable pricing based on nodes or users, not data volume.
  • Free SOAR seat included.
  • Seamless integrations with over 600 vendors.
  • Unified platform for SIEM, SOAR, UEBA, and endpoint security.
