The short version

  • Only DemandStar has a free tier, so it costs nothing to try first.
  • Each has a real cost: BigID pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.; 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.
  • They diverge on capability: BigID covers Structured and unstructured scanning, DemandStar covers Free for agencies.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

BigID

  • Pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.
  • Scanning large unstructured estates is slow and computationally expensive, so most organisations sample rather than scan everything, which reintroduces uncertainty into the very question they bought the tool to settle.
  • Classification accuracy on messy unstructured content requires tuning, and out of the box false positives on things like reference numbers create a large triage backlog that a small governance team cannot clear.
  • It discovers and reports but does not remediate, so realising value requires a separate process and often separate tooling to actually delete, restrict or move the data it flags.
  • It is built for large enterprises and both the price and the administrative overhead are disproportionate below a few thousand employees, where a lighter DSPM tool covers the security use case for far less.

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.

Answered from the vendors’ own pages

BigID: What does BigID cost?

It is quoted by data source count and volume. Reported contracts run from roughly 15,000 to 175,000 US dollars a year, and add-on modules such as AI security posture are licensed on top.

DemandStar: Is DemandStar free for governments?

Yes, entirely. Agencies post solicitations and access the supplier network at no cost; suppliers fund the platform.

BigID: Does it handle unstructured data?

Yes, and that is its main advantage. It classifies data in files and shares and correlates findings back to individuals, not just to data types.

DemandStar: What do suppliers pay?

Free for one agency with roughly 5 USD per document download, about 60 USD a year per county, 100 to 1,499 per state, and 2,699 for national coverage.

BigID: Will it delete the data it finds?

Not by itself in most deployments. It identifies and routes findings; deletion and remediation happen through your own processes or connected systems.

DemandStar: Who owns DemandStar?

Euna Solutions, the public sector portfolio formerly known as GTY Technology, which also absorbed Bonfire and Ion Wave.

BigID: Is it a privacy tool or a security tool?

Both are sold from the same discovery core. Buyers increasingly come from security wanting data security posture management rather than from legal wanting privacy.

DemandStar: Does it cover every agency?

No. Only agencies that have opted in, which is the main limitation for suppliers buying wide coverage.
