Procurement and architecture notes
Procurement guidance
Demand a data volume model tied to named sources before signature. Include a detection staffing plan. If staffing is unavailable, evaluate MDR-operated detection instead of owning Splunk pride.

Frequently asked questions
Do you publish a numeric SecurityCheckli.st rating on this page?
No. SecurityCheckli.st rating: Not assigned until evidence supports a published score. We will not invent a number to fill a table.
Are product capabilities independently verified?
Unless an evidence block marks a finding as confirmed, treat detailed capability claims as vendor-reported and validate them in your own tenancy or pilot.
Is Splunk only for huge enterprises?
It is most often justified at higher telemetry scale or with existing skills. Smaller orgs may prefer MDR or Sentinel depending on gravity.
Splunk vs Sentinel?
See the dedicated comparison page.
Do we need Splunk if we have MDR?
Not always. Some MDR models include analytics platforms. Keep transparency and export rights.
