The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: SentinelOne Singularity deployment and configuration requires professional services ($5,000 to $25,000); 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: SentinelOne Singularity covers Behavioral AI, Sigstore covers Fulcio.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

SentinelOne Singularity

  • Deployment and configuration requires professional services ($5,000 to $25,000)
  • Optional modules like Ranger and Vigilance add to total cost of ownership
  • Complex pricing tiers make budgeting difficult for large deployments

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

SentinelOne Singularity: What does SentinelOne Singularity XDR cover?

Singularity XDR unifies detection and response across endpoints, cloud, identity, network, and mobile, providing centralized visibility and automated response across all attack surfaces.

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.

SentinelOne Singularity: How does SentinelOne correlate data across security tools?

Singularity normalizes data from endpoints, identity, cloud, and third-party security tools into a unified data layer, enabling automatic correlation of signals without manual integration.

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.

SentinelOne Singularity: Can SentinelOne integrate with existing security tools?

Yes, Singularity Marketplace provides pre-built, one-click integrations with email, network, firewall, and SaaS security tools, avoiding vendor lock-in while extending detection capabilities.

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.

SentinelOne Singularity: What is the pricing model for SentinelOne Singularity?

SentinelOne pricing ranges from $5.83 to $17.50 per endpoint per month across five tiers, with optional add-on modules and enterprise pricing available on request.

Source
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.
