The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • They diverge on capability: NEXGEN Asset Management covers Esri GIS integration, Sigstore covers Fulcio.
  • 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.

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.

Sigstore

  • The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
  • Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
  • Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
  • Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages

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.

Sigstore: Is the public instance really free?

Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.

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.

Sigstore: Has the public log moved to Rekor v2?

No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.

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.

Sigstore: Does Sigstore make my dependencies safe?

No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.

NEXGEN Asset Management: Is there a mobile app?

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

Sigstore: What are the rate limits?

Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.

Sigstore: Should we self-host it?

If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
