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.; NEOGOV each module is shallower than the specialist product it competes with, so agencies buying the full suite for coherence accept weaker performance management and learning than they would get separately.
- They diverge on capability: Cosign covers Keyless signing, NEOGOV covers Civil service recruiting.
- 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.
NEOGOV
- Each module is shallower than the specialist product it competes with, so agencies buying the full suite for coherence accept weaker performance management and learning than they would get separately.
- Policy management arrived through the PowerDMS acquisition rather than being built in, and the join between it and the rest of the suite still reads as two products.
- Implementation is long and configuration heavy because the civil service rules that make the product valuable have to be encoded for your jurisdiction, and that work is billed.
- Pricing is not published and scales with headcount, so a large agency can pay several times what a comparable one pays without knowing it unless someone reads the public contracts.
- Private equity ownership since the Warburg Pincus investment has coincided with an acquisition led strategy, and buyers should expect further products bolted on rather than deeper integration of the existing ones.

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.
NEOGOV: Why not use a commercial applicant tracking system?
Because civil service rules such as ranked eligibility lists, rule of three certification and veterans preference are not expressible in commercial products, so the statutory steps end up in spreadsheets.
Cosign: Is signing alone enough?
No. Verification is a command somebody runs. Without an admission controller enforcing it, an unsigned image still runs.
NEOGOV: Can I find out what other agencies pay?
Yes. These are public procurements, so executed contract values appear in council agenda packets and state term contract listings. Read several before negotiating.
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.
NEOGOV: What did NEOGOV acquire?
PowerDMS, a policy management and accreditation product, in 2021, which is now sold as the policy module of the suite.
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.
NEOGOV: Is it only for the United States?
Effectively yes. The value is in encoding US civil service and public safety requirements.
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.
