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.; LogicManager the flat fee is quoted per organisation and not published, so the pricing model that makes LogicManager attractive still cannot be compared without a sales process.
  • They diverge on capability: Cosign covers Keyless signing, LogicManager covers Risk taxonomy.
  • 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.

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.

LogicManager

  • The flat fee is quoted per organisation and not published, so the pricing model that makes LogicManager attractive still cannot be compared without a sales process.
  • Configuration depth means the taxonomy has to be designed properly before rollout, and organisations that skip that step end up with a structure that cannot answer the linkage questions the tool exists to answer.
  • Reporting and dashboarding are functional rather than flexible, and teams wanting bespoke board reporting commonly export to Power BI, which reintroduces the manual step they were removing.
  • Quantitative risk modelling is limited compared with specialist tools, so organisations needing Monte Carlo style loss simulation will need something else alongside it.
  • The user interface is dated relative to newer compliance automation tools, and infrequent business users often need repeat training, which erodes the participation benefit that unlimited licensing is supposed to deliver.

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.

LogicManager: Is LogicManager really unlimited users?

Yes. It licences on a fixed annual fee covering the organisation rather than per seat, which is the main reason mid-market buyers pick it.

Cosign: Is signing alone enough?

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

LogicManager: What does it cost?

Not published. Mid-market ERM platforms of this class typically sit in the low tens of thousands of dollars a year, quoted by scope.

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.

LogicManager: Is it a compliance automation tool like Drata?

No. It is enterprise risk management with audit and vendor risk, not continuous control monitoring for SOC 2 evidence collection.

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.

LogicManager: How long does implementation take?

Weeks to a few months, far shorter than the enterprise GRC suites, provided the risk taxonomy is agreed up front.

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.
