The short version

  • Each has a real cost: DemandStar coverage is opt-in by agency, so a supplier paying for a state tier receives only participating agencies and must still monitor other portals for the rest.; Microsoft Sentinel billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • They diverge on capability: DemandStar covers Free for agencies, Microsoft Sentinel covers AI-powered analytics.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

DemandStar

  • Coverage is opt-in by agency, so a supplier paying for a state tier receives only participating agencies and must still monitor other portals for the rest.
  • The free supplier tier charges around 5 US dollars per bid document download, which turns an apparently free plan into a metered one as soon as you actually pursue opportunities.
  • State pricing ranges from roughly 100 to 1,499 US dollars with the variation driven by agency density, so suppliers cannot predict cost from geography alone.
  • Because agencies pay nothing, they have little leverage over the roadmap and features are driven by what makes supplier subscriptions sell.
  • The brand is being folded into Euna OpenBid following the Euna Solutions consolidation, so suppliers and agencies should expect the name and portal to change.

Microsoft Sentinel

  • Billing is driven by the volume of log data ingested per day, so cost scales with log noise rather than with users or protected assets
  • Commitment tier discounts require reserving daily ingestion capacity in advance, and a tier cannot be downgraded until 31 days have passed
  • Commitment tiers start at 100 GB per day, above what smaller estates ingest
  • Charges for Log Analytics, Logic Apps and Machine Learning are billed separately on top of Sentinel itself
  • The free allowance is only up to 5 MB per user per day for selected Microsoft 365 security logs
  • Promotional commitment pricing is time limited and locks in only until a stated end date
