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.; Falco falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • They diverge on capability: DemandStar covers Free for agencies, Falco covers eBPF kernel instrumentation.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

DemandStar

  • A city purchasing officer who wants wider bid distribution without running a procurement to buy softwarenot Falco
  • A contractor who works in three adjacent counties and wants notifications only for that footprintnot Falco
  • An agency needing sealed electronic bid submission to replace paper deliveries to the clerknot Falco
  • A supplier testing whether public sector work is viable before committing to a national subscriptionnot Falco

Falco

  • A platform team that needs to know when a shell is opened inside a production container, which image scanning cannot detect because it happens at runtimenot DemandStar
  • A regulated business required to evidence host and container intrusion detection on Kubernetes nodes for an auditnot DemandStar
  • A security team wanting a vendor-neutral detection layer whose rules they can read and modify rather than a black-box agentnot DemandStar
  • A cluster where a compromised dependency might write to sensitive paths or open unexpected outbound connections, and only kernel-level visibility will catch itnot DemandStar

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.

Falco

  • Falco detects and alerts but does not block; stopping an attack requires wiring up Falco Talon or your own response tooling, so out of the box a confirmed detection still means a human intervening after the fact.
  • The default rule set is noisy in real clusters and generates a large volume of benign matches from normal operational activity; without weeks of tuning, alert fatigue sets in and the team stops reading the feed, which is the usual failure mode.
  • There is no storage, console, search or case management in the project, so a working detection capability means also running Falcosidekick, an event store, a dashboard and alert routing, all of which you build, host and maintain.
  • The modern eBPF driver requires kernel 5.8 or later; older hosts fall back to the legacy probe or the kernel module, which brings driver-building against kernel headers and the operational fragility that comes with it on every kernel upgrade.
  • Per-node syscall instrumentation carries measurable CPU overhead on busy hosts, and the cost scales with syscall volume rather than with cluster size, so the noisiest and most performance-sensitive workloads are exactly the ones that feel it most.

Answered from the vendors’ own pages

DemandStar: Is DemandStar free for governments?

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

Falco: Does Falco block attacks?

No. It detects and emits events. Response requires Falco Talon or your own automation on top.

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.

Falco: Is Falco owned by Sysdig?

Sysdig created and open sourced it, but it graduated within the CNCF in February 2024, so governance sits with the foundation rather than the vendor.

DemandStar: Who owns DemandStar?

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

Falco: What does it cost?

The project is Apache 2.0 with no licence fee. The cost is the storage, routing, tuning and staff time needed to make its output useful.

DemandStar: Does it cover every agency?

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

Falco: What kernel version do I need?

Kernel 5.8 or later for the default modern eBPF driver. Older hosts need the legacy eBPF probe or the kernel module.
