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.; HID Global sales run through integrators, so the price you get depends on which partner quotes it and there is no published list to negotiate against.
  • They diverge on capability: Cosign covers Keyless signing, HID Global covers Physical access readers.
  • 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.

HID Global

  • Sales run through integrators, so the price you get depends on which partner quotes it and there is no published list to negotiate against.
  • Mobile credentials are charged per identity as an ongoing fee, which converts a one-off card cost into a recurring per-employee subscription that budgets rarely anticipate.
  • Large estates run mixed generations of readers, so a credential upgrade is a multi-year hardware programme and the software licence is a small fraction of the true cost.
  • Legacy credential technologies still widely deployed have documented cloning weaknesses, and HID commercial interest in selling the replacement does not remove your exposure in the interim.
  • The portfolio spans hardware, firmware and several acquired software products, so integration between HID own components is less consistent than the single-vendor pitch implies.

Does Cosign or HID Global run on more platforms?
Cosign runs on macOS, Linux, Windows, Docker. HID Global runs on Web, Windows, iOS, Android.
Can I use Cosign for free?
Yes. Cosign has a free tier, so you can try it without paying. HID Global starts at On request.
What is Cosign best used for?
Cosign is most often used for signing container images in a build pipeline without managing long-lived private keys, attaching a signed bill of materials to a release so consumers can verify its provenance, meeting a customer or regulatory requirement for signed artifacts, verifying third-party images before they enter an internal registry. Of those, signing container images in a build pipeline without managing long-lived private keys and attaching a signed bill of materials to a release so consumers can verify its provenance are not what HID Global is typically brought in for.
What can Cosign do that HID Global cannot?

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.

HID Global: Do we have to replace readers to use mobile credentials?

Often yes, at least in part. Reader capability determines which credential technologies work, and that hardware cost dominates the business case.

Cosign: Is signing alone enough?

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

HID Global: Are mobile credentials cheaper than cards?

Not necessarily. Cards are a one-off cost per employee, mobile identities are typically a recurring charge, so the crossover depends on staff turnover.

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.

HID Global: Can we buy directly from HID?

Generally not for access control deployments. Products are sold and installed through channel partners, so partner selection is part of the buying decision.

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.
