The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Shufti Pro rates are not published despite the pay as you go framing, so the cost advantage over premium vendors has to be established through a quote rather than a price list.; 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: Shufti Pro covers Document verification, Sigstore covers Fulcio.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Shufti Pro

  • Rates are not published despite the pay as you go framing, so the cost advantage over premium vendors has to be established through a quote rather than a price list.
  • Accuracy on difficult document types trails the premium vendors, and the saving per check is often consumed by the manual review headcount handling the additional referrals.
  • The enterprise assurance profile is thinner than that of larger competitors, so regulated bank procurement teams frequently rule it out at the vendor risk stage rather than on capability.
  • Support responsiveness scales with contract size, and pay as you go customers have limited recourse when a document type suddenly starts failing in one market.
  • Country coverage is broad but uneven in depth, meaning the same product can perform very differently across two markets you are launching in simultaneously.

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

Shufti Pro: Are failed attempts charged?

Shufti states that resubmission sessions are not charged and that billing follows successful verification attempts. Get that written into the contract, because it materially changes total cost.

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.

Shufti Pro: Is there a published price?

No. Plan structures are published but rates are quoted. Third party estimates put effective cost well below premium vendors.

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.

Shufti Pro: Can we start without a commitment?

Yes. A pay as you go option exists, which is unusual in this category and useful for early stage volume.

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.

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.
