SIEM cost calculator: frequently asked questions
Which SIEM vendors does this calculator benchmark against?
The calculator uses published list pricing and publicly available Gartner and Forrester TCO data for Splunk Enterprise, Microsoft Sentinel, IBM QRadar, and Elastic SIEM. Your mileage will vary based on negotiated discounts.
Does the calculator include infrastructure costs?
Yes. The estimate includes licence fees, storage (hot and warm tiers), compute, and a 20% factor for administration overhead. You can toggle individual line items on or off.
How accurate is the ManySignal cost estimate?
The ManySignal side of the estimate uses list pricing for the appropriate tier based on the number of protected assets you enter. Contact sales for a tailored quote against your specific environment.
Does the calculator account for professional services and onboarding?
Standard onboarding is included in ManySignal pricing. The calculator adds a one-time migration effort line item for the legacy SIEM side. You can edit this figure.
Can I use this calculator for a board presentation?
Yes. The PDF export includes a methodology note and source citations suitable for executive audiences. We recommend having ManySignal's solutions engineering team validate the numbers before board presentation.
What if my current SIEM is cloud-native like Microsoft Sentinel?
Select 'Sentinel' from the vendor dropdown. The calculator uses Microsoft's published Analytics and Basic Logs pricing tiers and models your commitment-tier discount.
Does the saving estimate include analyst time savings?
The basic view focuses on licence and infrastructure. Enable 'Include operational savings' to add analyst hours recovered from automated triage — benchmarked at 3.2 hours per analyst per shift.
Why does the saving vary so much with data volume?
Per-GB SIEM pricing creates steep cost curves at high data volumes. The saving grows non-linearly because ManySignal's per-asset model does not penalise you for collecting more logs.
How do I get a formal quote to replace my SIEM?
After running the calculator, click 'Book a sizing call.' A solutions engineer will review your inputs and produce a binding commercial proposal within two business days.
