The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Intune individual add-ons at $2-5/user/month can become expensive when deploying multiple modules; 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.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft Intune

  • Individual add-ons at $2-5/user/month can become expensive when deploying multiple modules
  • Full Intune Suite at $10/user/month becomes better value when deploying two or more modules

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

Microsoft Intune: How much does Microsoft Intune cost?

Microsoft Intune Plan 1 costs $8/user/month for basic device management. The full Intune Suite costs $10/user/month including endpoint privilege management, enterprise application management, advanced analytics, remote help, Intune Plan 2, and Microsoft Cloud PKI.

Source
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.

Microsoft Intune: What add-ons are available for Microsoft Intune?

Individual Intune Suite add-ons range from $2-5/user/month and include Endpoint Privilege Management, Enterprise Application Management, Advanced Analytics, Remote Help, Intune Plan 2, and Microsoft Cloud PKI. Microsoft recommends the full Intune Suite at $10/user/month when deploying two or more modules for better value.

Source
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.

Microsoft Intune: Is Intune included in Microsoft 365 E5?

Starting in CY26 Q3, Intune Suite capabilities are included with Microsoft 365 E5 and E7 subscriptions, with select capabilities also in Microsoft 365 E3. These bundled versions do not have separate additional pricing.

Source
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.
