  • They diverge on capability: Cosign covers Keyless signing, McAfee Total Protection covers Real-time antivirus.
  • 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.

Cosign

  • Keyless signing inherits every weakness of the identity provider behind it. Sigstore’s own threat model states that if an identity provider is compromised, Sigstore will issue certificates to those identities, so a compromised account produces perfectly valid signatures.
  • A signature proves who signed, never whether they should have. The documentation is explicit that Sigstore cannot determine authorisation, so every consumer must write and maintain their own identity and issuer policy or verification means nothing.
  • Nothing is enforced without an admission controller. Signing changes what you can prove, not what runs, and the official policy controller has a small maintainer base for a component sitting in a cluster admission path.
  • Upgrades break pipelines. Version 3 changed defaults, version 4 is announced as removing legacy functionality and roughly half the command line flags, and two official client libraries still lacked support for the new log format as of mid 2026.
  • Signatures do not expire. An artifact signed before a maintainer account was compromised and one signed after are indistinguishable unless somebody is actively monitoring the transparency log, and almost nobody is.

McAfee Total Protection

  • Significant renewal price increase after first year (from $29.99 to $84.99/year)
  • Customer support responsiveness issues reported as reason for switching
  • Renewal billing can be aggressive with auto-renewal defaults

Answered from the vendors’ own pages

Cosign: Does Cosign tell me if an image is vulnerable?

No. It has no vulnerability knowledge whatsoever. It can carry an SBOM as a signed attestation but never reads it. Pair it with a scanner.

McAfee Total Protection: How much does McAfee Total Protection cost?

McAfee Total Protection introductory pricing ranges from $29.99/year (Basic) to $74.99/year (Advanced), but renewal costs jump to $84.99/year after the first year.

Source
Cosign: Is signing alone enough?

No. Verification is a command somebody runs. Without an admission controller enforcing it, an unsigned image still runs.

McAfee Total Protection: What is the trial period for McAfee Total Protection?

McAfee offers a 60-day money-back guarantee, allowing you to try the service risk-free for two months.

Source
Cosign: What does a bare cosign verify actually prove?

Very little. Without a pinned certificate identity and OIDC issuer, it accepts a valid signature from any identity at all.

McAfee Total Protection: How many devices can I protect with one McAfee Total Protection subscription?

Device coverage varies by plan: Basic covers 1 device, while other plans protect 5 to unlimited devices depending on the tier selected.

Source
Cosign: What is the risk of keyless signing?

Your OIDC provider becomes the root of trust. Compromise of that account yields genuine, verifiable signatures, so account security is the control that matters.

McAfee Total Protection: Does McAfee Total Protection include VPN?

VPN is included in higher-tier McAfee plans if you opt for auto-renewal.

Source
Cosign: Should we expect breaking changes?

Yes. Version 4 is announced to remove roughly half the flags, and a post-quantum migration is named as a further breaking change after that.
