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.; NEXGEN Asset Management pricing keys off asset count, so a routine GIS resegmentation that splits mains into more records can raise your subscription without adding a single user or work order.
  • They diverge on capability: Cosign covers Keyless signing, NEXGEN Asset Management covers Esri GIS integration.
  • 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.

NEXGEN Asset Management

  • Pricing keys off asset count, so a routine GIS resegmentation that splits mains into more records can raise your subscription without adding a single user or work order.
  • Nothing is published and the vendor is small, so the reference set you can call is limited and mostly Californian and North American public agencies.
  • The interface is dated compared with modern CMMS products, which hurts adoption among field crews who compare it to consumer apps on their own phones.
  • GIS integration is the product strength and also its dependency; agencies without a maintained ArcGIS asset layer face a data preparation project before NEXGEN is useful.
  • As a small vendor it carries acquisition risk, and in this segment acquisitions have repeatedly meant a product frozen while it is folded into a larger portfolio.

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.

NEXGEN Asset Management: How is NEXGEN priced?

On a tiered model based on the number of assets under management, quoted per agency. Nothing is published.

Cosign: Is signing alone enough?

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

NEXGEN Asset Management: Do we need Esri ArcGIS?

Not strictly, but the product is designed around it and most of the value assumes a maintained GIS asset layer.

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.

NEXGEN Asset Management: Does it handle capital planning?

Yes. Risk, criticality and condition scores feed multi-year renewal forecasts intended for board and council submissions.

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.

NEXGEN Asset Management: Is there a mobile app?

Yes, a map-based field application with offline capability, licensed alongside the core platform.

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.
