The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Omada Identity pricing is per managed identity, so organisations with large numbers of contractors, service accounts or seasonal staff pay governance fees on identities nobody is really governing.; 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: Omada Identity covers Access certification, 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.

Omada Identity

  • Pricing is per managed identity, so organisations with large numbers of contractors, service accounts or seasonal staff pay governance fees on identities nobody is really governing.
  • It governs access but provides no single sign-on, multi-factor authentication or privileged session management, so it is always a second or third identity subscription rather than a consolidation.
  • The fast-deployment promise depends on accepting its standard process model; organisations with genuinely unusual entitlement structures end up in custom work and the timeline advantage disappears.
  • Connector coverage is strong for mainstream enterprise systems and thin for bespoke or industry-specific applications, and each custom connector is a project with ongoing maintenance.
  • Data quality in the HR system determines whether joiner mover leaver automation works, so companies with messy HR records find the tool exposes that problem rather than solving it.

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

Omada Identity: Does it provide single sign-on?

No. Omada is governance only. You still need Entra ID, Okta or equivalent for authentication.

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.

Omada Identity: How is it licensed?

Per managed identity per year. Count contractors and service accounts before you compare quotes, because they usually count.

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.

Omada Identity: How long does deployment take?

Months rather than years is the positioning, and it is achievable if you accept the standard process model. Heavy customisation returns you to traditional IGA timelines.

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.

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.
