The short version

  • Only Cosign has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bang the Table the Internet Archive's capture of Bang the Table's homepage on 29 December 2020 confirmed its EngagementHQ platform is sold only via demo request, with EngagementIQ support offered as separate 'annual success plan options'; no price figure is published for either.; 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.
  • They diverge on capability: Bang the Table covers Online Surveys, Cosign covers Keyless signing.
  • 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.

Bang the Table

  • The Internet Archive's capture of Bang the Table's homepage on 29 December 2020 confirmed its EngagementHQ platform is sold only via demo request, with EngagementIQ support offered as separate 'annual success plan options'; no price figure is published for either.

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

Bang the Table: What solutions does Granicus provide?

Granicus offers Service Cloud for frictionless service delivery, Engagement Cloud for growing and activating audiences, Operations Cloud for automating workflows and reducing costs, and Government Experience Agent for 24/7 self-service with digital agents.

Source
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.

Bang the Table: Who does Granicus serve?

Granicus serves local government, state government, education, elected officials, federal government, and special districts. It helps organizations deliver better citizen experiences and improve government efficiency.

Source
Cosign: Is signing alone enough?

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

Bang the Table: Does Granicus offer AI solutions?

Yes, Granicus AI Hub provides secure, ethical AI solutions built exclusively for the public sector to transform services without compromising public trust.

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.

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.
