The short version

  • Each has a real cost: Kaspersky Total Security uS sales banned since June 2024 with support ending September 29, 2024; 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: Kaspersky Total Security covers Real-time protection, 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.

Kaspersky Total Security

  • US sales banned since June 2024 with support ending September 29, 2024
  • VPN limited to 200 MB per day and servers in only 24 countries
  • Password manager has privacy concerns with questionable terms and policies
  • VPN and password manager only included in Plus and Premium tiers, not in Standard
  • Occasionally flags legitimate files as false positives
  • Firewall leaves open ports on public networks

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

Kaspersky Total Security: What does Kaspersky Total Security include?

Kaspersky Total Security (Premium tier) includes antivirus, firewall, password manager, VPN with 200 MB daily limit, parental controls (Kaspersky Safe Kids), and anti-ransomware protection.

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.

Kaspersky Total Security: How much does Kaspersky Total Security cost?

Kaspersky Standard costs $38.99/year for 3 devices. Plus tier is $52.99/year for 5 devices. Premium is $74.99/year for 10 devices. Multi-year discounts available.

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.

Kaspersky Total Security: Is Kaspersky available in the United States?

No. The U.S. government banned Kaspersky software sales in June 2024, with support and software updates ceasing September 29, 2024, citing national security concerns regarding Russian government ties.

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.

Kaspersky Total Security: Does Kaspersky have parental controls?

Yes. Premium and Plus tiers include one year free access to Kaspersky Safe Kids parental controls app, which provides activity reports, app monitoring, usage limits, and geo-fencing with location tracking.

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.

Kaspersky Total Security: How much does the VPN provide?

Kaspersky's free VPN (Kaspersky Secure Connection) offers only 200 MB per day of traffic, limiting data usage. Full VPN is included in Plus and Premium plans but with limited servers in only 24 countries.

Source
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.
