The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Euna Solutions the suite is assembled from six or more separate acquisitions and integration between modules is still being completed, so a buyer purchasing two modules should ask precisely what data passes between them today rather than on the roadmap.; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • They diverge on capability: Euna Solutions covers Euna Budget, Sigstore covers Fulcio.
  • 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.

Euna Solutions

  • The suite is assembled from six or more separate acquisitions and integration between modules is still being completed, so a buyer purchasing two modules should ask precisely what data passes between them today rather than on the roadmap.
  • No pricing is published at any level and terms are typically multi-year, so budgeting the true cost requires obtaining peer jurisdiction contracts, which is possible but slow.
  • Individual modules face specialists with deeper functionality, so a jurisdiction buying only procurement or only budgeting may get less capability than from a single-product vendor at similar cost.
  • Ownership has changed twice in six years, from a SPAC to private equity, and further change is plausible, which creates roadmap uncertainty over the length of a typical multi-year public sector contract.
  • Grant management depth is oriented to United States federal and state programmes, which makes the product close to useless to public bodies outside that funding system.

Sigstore

  • The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
  • Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
  • Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
  • Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages

Euna Solutions: Is this the same company as GTY Technology?

Yes. GTY Technology rebranded to Euna Solutions in 2023. The individual products came from acquisitions including Bonfire, Questica, eCivis and CityBase.

Sigstore: Is the public instance really free?

Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.

Euna Solutions: Which product was Bonfire?

Bonfire is now Euna Procurement. Questica became Euna Budget and eCivis became Euna Grants. Ask which underlying codebase a demo is showing.

Sigstore: Has the public log moved to Rekor v2?

No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.

Euna Solutions: What does it cost?

Not published. Modules are quoted individually by jurisdiction size and users, usually on multi-year terms and often available through cooperative purchasing contracts.

Sigstore: Does Sigstore make my dependencies safe?

No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.

Euna Solutions: Do the modules actually share data?

Partially, and it varies by pair. Get the specific integration between the modules you are buying demonstrated on real data before signing.

Sigstore: What are the rate limits?

Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.

Sigstore: Should we self-host it?

If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
