The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Norton 360 device limit of 3 devices on Standard plan; higher tiers needed for family with multiple devices; 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: Norton 360 covers Real-time threat 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.

Norton 360

  • Device limit of 3 devices on Standard plan; higher tiers needed for family with multiple devices
  • Parental controls unavailable on Standard plan, requiring purchase of separate Norton Family app
  • No HIPAA compliance or BAA support for regulated industries
  • Exploit Prevention works only on Windows devices, not available for macOS
  • Limited account recovery options if master password is forgotten

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

Norton 360: What operating systems does Norton 360 Standard support?

Windows 7 SP1 through Windows 11, macOS 10.13 and later, Android 10.0 or later, and current plus two previous iOS versions. Not all features are available on all platforms.

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.

Norton 360: How much cloud backup storage is included in Norton 360 Standard?

2 GB of cloud backup storage is included with Norton 360 Standard. Higher tiers offer 50 GB (Deluxe) and 250 GB (Premium).

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.

Norton 360: Does Norton 360 include a VPN?

Yes. All Norton 360 plans include a VPN for secure browsing. The VPN is available on Windows, Mac, iOS, and Android devices.

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.

Norton 360: Is Norton 360 HIPAA compliant?

No. Norton 360 does not offer HIPAA compliance or Business Associate Agreements (BAA), making it unsuitable for healthcare organizations handling protected health information (PHI).

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.

Norton 360: What is the renewal price after the first year?

First year pricing is discounted. Standard renews at 94.99 USD per year, Deluxe at 119.99 USD per year. This represents a 140% increase over Deluxe's first-year rate of 49.99 USD.

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.
