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.; ShotSpotter shotSpotter now trades as SoundThinking and shotspotter.com redirects to soundthinking.com
They diverge on capability: Cosign covers Keyless signing, ShotSpotter covers Gunshot Detection.

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.

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.

ShotSpotter: Does SoundThinking publish ShotSpotter pricing?

No. SoundThinking does not disclose ShotSpotter pricing on their website. Interested municipalities and organizations must request a consultation, contact the sales team, or book a demo.

Source

Cosign: Is signing alone enough?

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

ShotSpotter: How do I get a ShotSpotter quote?

SoundThinking directs prospects to book a demo, contact them directly, or request a consultation through their website. No self-serve pricing, calculator, or trial is available.

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.

ShotSpotter: Who is ShotSpotter for?

ShotSpotter is a gunshot detection system designed for law enforcement and municipalities to improve public safety response.

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.
