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.; JumpCloud platform Essentials tier capped at 300 users; larger organisations must purchase unbundled tiers or negotiate custom pricing
  • 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.

JumpCloud

  • Platform Essentials tier capped at 300 users; larger organisations must purchase unbundled tiers or negotiate custom pricing
  • À la carte pricing can become expensive when purchasing multiple features; device management at $9/user, SSO at $11/user totals $20/user for basic functionality
  • Bundled Platform and Platform Prime packages require contacting sales; no published pricing limits transparency
  • Zero-trust and AI & SaaS management capabilities only available in Platform Prime tier with custom pricing
  • No on-premises or self-hosted option; cloud-only deployment

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.

JumpCloud: What devices does JumpCloud support?

JumpCloud supports unified endpoint management for Windows, macOS, Linux, iOS and Android devices.

Source
Cosign: Is signing alone enough?

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

JumpCloud: Can I use JumpCloud to replace Active Directory?

Yes. JumpCloud is designed for organisations modernising from on-premises Active Directory to cloud-based directory and identity management.

Source
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.

JumpCloud: Is there a free trial?

Yes. All users can access a 30-day free trial before purchasing.

Source
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.
