The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: SentinelOne enterprise pricing requires contacting sales; 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 covers AI-powered detection, 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

  • Enterprise pricing requires contacting sales
  • Prices shown for 5-100 workstations may differ for larger deployments
  • Purchases must be made through authorized third-party partners

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: What is SentinelOne Singularity Complete pricing?

Singularity Complete costs $179.99 per endpoint per year and includes AI-driven endpoint and cloud workload protection, real-time threat detection and response, 14-day data retention, and AI Security Assistant. Pricing shown for 5-100 workstations.

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: What features distinguish SentinelOne Commercial from Complete?

Singularity Commercial costs $229.99 per endpoint per year (versus $179.99 for Complete) and adds Identity Detection and Response, 90-day data retention (compared to 14-day), and Managed Threat Hunting services.

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: How does partner pricing affect SentinelOne costs?

All SentinelOne purchases are made through authorized third-party partners, and partner pricing may differ from published rates. Customers should verify pricing with their authorized reseller.

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: What does SentinelOne Enterprise include?

Singularity Enterprise (custom pricing, contact sales) adds Agentic AI SOC Analyst and Full Visibility and Forensics capabilities to all Commercial features, plus expert-led onboarding and training.

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.
