The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Ping Identity workforce pricing carries a 5,000 user annual minimum, so an organisation with 800 staff pays for 5,000 and the effective per user cost is over six times the list rate.; 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: Ping Identity covers Single sign-on, 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.

Ping Identity

  • Workforce pricing carries a 5,000 user annual minimum, so an organisation with 800 staff pays for 5,000 and the effective per user cost is over six times the list rate.
  • Adaptive multi-factor authentication is in the Plus tier only, doubling the per user price for a capability many buyers assume is standard in a modern identity platform.
  • ForgeRock no longer exists as an independent product, so customers who chose it specifically to avoid Ping now face a roadmap set by the vendor they did not pick.
  • Thoma Bravo ownership across both merged companies means the commercial priority is margin, and buyers report firmer renewal negotiations than they saw before 2022.
  • The portfolio has overlapping components from three product lineages, so scoping a deployment requires vendor architects and the licensing conversation is more complicated than the price list implies.

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

Ping Identity: Can I still buy ForgeRock?

Not as a separate product. Ping acquired ForgeRock in 2023 and the capabilities are sold within the Ping portfolio. Existing customers should ask about the specific migration path for their components.

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.

Ping Identity: What is the real minimum spend?

PingOne for Workforce Essential is 3 USD per user per month with a 5,000 user annual minimum, so roughly 180,000 USD a year before anything else.

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.

Ping Identity: Is MFA included?

Basic authentication policies are in Essential. Adaptive MFA and passwordless require the Plus tier at 6 USD per user per month.

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.
