The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Trend Micro Vision One licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • They diverge on capability: Sigstore covers Fulcio, Trend Micro Vision One covers Cross-layer correlation.
  • 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.

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.

Trend Micro Vision One

  • Licensing is a credit pool consumed at different rates by different modules, so forecasting a renewal means modelling which capabilities you will activate rather than counting users, and switching on a new module silently draws down the budget for an existing one.
  • Retention in the XDR data lake beyond the included window is bought with additional credits, so the retrospective hunting the platform is sold on is precisely the part with an ongoing meter attached, and teams shorten retention to control spend.
  • The correlation that justifies the platform only exists over deployed Trend sensors, so an organisation running only the endpoint agent gets an EDR with a large console, and reaching the advertised value means a de facto single-vendor commitment across email, network and workload.
  • Legacy management planes persist: Apex Central, Deep Security Manager and the older Cloud One consoles overlap with Vision One and migrations have run for years, so administrators frequently maintain two consoles for the same agents and learn both.
  • The agents hook file and network operations, so on build servers, database hosts and developer machines the overhead is noticeable, and the standard remedy is broad path exclusions that remove protection from exactly the directories where attackers stage tooling.

Answered from the vendors’ own pages

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.

Trend Micro Vision One: What are Trend Micro Credits?

A single purchased pool of licensing units drawn down by whichever Vision One modules you activate, at different rates per module and per protected object. It replaces separate per-product subscriptions and shifts the forecasting problem onto you.

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.

Trend Micro Vision One: Is this the same thing as Deep Security?

Not the same, but related. Server and workload protection in Vision One descends from Deep Security, and Trend has been migrating Deep Security and Cloud One Workload Security customers onto the Vision One platform. Existing Deep Security deployments still exist in the field.

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.

Trend Micro Vision One: Does it replace my SIEM?

No. It correlates and retains telemetry from Trend sensors and selected third parties, but it is not a general-purpose log store for every system in the estate, and compliance log retention requirements are usually still met elsewhere.

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.

Trend Micro Vision One: Do I have to use Trend endpoint protection?

To get real value, effectively yes. Third-party ingestion exists but the correlation quality depends on Trend's own sensor telemetry, and a Vision One deployment over someone else's endpoint agent is not what the platform is designed around.

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.

Trend Micro Vision One: Where is the data held?

In the regional instance you choose at onboarding. Confirm the specific region against your residency obligations before deployment, because moving afterwards is a migration.
