The short version

  • Only Cosign has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cosign keyless signing inherits every weakness of the identity provider behind it. Sigstore’s own threat model states that if an identity provider is compromised, Sigstore will issue certificates to those identities, so a compromised account produces perfectly valid signatures.; 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.
  • They diverge on capability: Cosign covers Keyless signing, Shufti Pro covers Document verification.
  • 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.

Cosign

  • Keyless signing inherits every weakness of the identity provider behind it. Sigstore’s own threat model states that if an identity provider is compromised, Sigstore will issue certificates to those identities, so a compromised account produces perfectly valid signatures.
  • A signature proves who signed, never whether they should have. The documentation is explicit that Sigstore cannot determine authorisation, so every consumer must write and maintain their own identity and issuer policy or verification means nothing.
  • Nothing is enforced without an admission controller. Signing changes what you can prove, not what runs, and the official policy controller has a small maintainer base for a component sitting in a cluster admission path.
  • Upgrades break pipelines. Version 3 changed defaults, version 4 is announced as removing legacy functionality and roughly half the command line flags, and two official client libraries still lacked support for the new log format as of mid 2026.
  • Signatures do not expire. An artifact signed before a maintainer account was compromised and one signed after are indistinguishable unless somebody is actively monitoring the transparency log, and almost nobody is.

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.

Answered from the vendors’ own pages

Cosign: Does Cosign tell me if an image is vulnerable?

No. It has no vulnerability knowledge whatsoever. It can carry an SBOM as a signed attestation but never reads it. Pair it with a scanner.

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.

Cosign: Is signing alone enough?

No. Verification is a command somebody runs. Without an admission controller enforcing it, an unsigned image still runs.

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.

Cosign: What does a bare cosign verify actually prove?

Very little. Without a pinned certificate identity and OIDC issuer, it accepts a valid signature from any identity at all.

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.

Cosign: What is the risk of keyless signing?

Your OIDC provider becomes the root of trust. Compromise of that account yields genuine, verifiable signatures, so account security is the control that matters.

Cosign: Should we expect breaking changes?

Yes. Version 4 is announced to remove roughly half the flags, and a post-quantum migration is named as a further breaking change after that.
