The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: CyberGhost VPN kape Technologies, the parent, was formerly Crossrider, a browser extension platform whose technology was widely used to distribute adware, and Kape now also owns VPN review sites, so third-party rankings a buyer might use to verify the product can come from the same corporate group.; 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: CyberGhost VPN covers NoSpy servers, 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.

CyberGhost VPN

  • Kape Technologies, the parent, was formerly Crossrider, a browser extension platform whose technology was widely used to distribute adware, and Kape now also owns VPN review sites, so third-party rankings a buyer might use to verify the product can come from the same corporate group.
  • Pricing is structured so that the deep discount applies to the longest initial term and the standard rate applies at renewal, which means the figure used to make the decision is not the figure paid in year three unless the subscriber renegotiates or churns.
  • The Deloitte engagement is point-in-time assurance over stated policy and server configuration, so it confirms things were as described when examined and says nothing about how the infrastructure behaves today or after an ownership change.
  • Client capability differs sharply by platform: the Linux client is command-line only and lacks the kill switch and split tunnelling that the Windows client has, so a mixed-device household does not get the protection that reviews of the Windows app describe.
  • Streaming-optimised server labels go stale because platforms block address ranges continually, and the practical support answer is to try a different server, which makes the labelled-server feature less dependable than the marketing 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

CyberGhost VPN: Who owns CyberGhost?

Kape Technologies, which acquired it in 2017. Kape was formerly called Crossrider and also owns ExpressVPN, Private Internet Access and Zenmate, plus the review sites vpnMentor and Wizcase.

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.

CyberGhost VPN: Has the no-logs claim been independently audited?

Yes. Deloitte has examined the no-logs policy and server configuration and published an assurance report. Note that this is a point-in-time engagement, not continuous monitoring.

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.

CyberGhost VPN: What jurisdiction is it under?

The service is operated from Romania, which has no mandatory communications data retention law in force and is not a member of the Five, Nine or Fourteen Eyes intelligence-sharing arrangements. Ownership sits with Kape, headquartered in the UK.

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.

CyberGhost VPN: Does it work with streaming services?

Often, using the servers labelled for each service, but this changes constantly as platforms block address ranges. Treat streaming access as a feature that may stop working on any given day rather than a guarantee.

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.

CyberGhost VPN: Can I use it on Linux or a router?

There is a command-line Linux client with fewer features than the desktop apps, and router use requires manual OpenVPN configuration rather than an official app.

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.
