  • Each has a real cost: 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.; ESET NOD32 Antivirus the advertised price applies to the first term only, and renewal reverts to the official list price
  • They diverge on capability: Cosign covers Keyless signing, ESET NOD32 Antivirus covers Antivirus & Antispyware.
  • 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.

ESET NOD32 Antivirus

  • The advertised price applies to the first term only, and renewal reverts to the official list price
  • Any saving shown is the difference between the introductory price and that list price rather than an ongoing discount
  • Device coverage is chosen at purchase and priced accordingly, so protecting another machine means changing the licence

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.

ESET NOD32 Antivirus: Does ESET offer a free trial, and what do I get access to?

ESET offers a free 30-day trial with no credit card required. The trial includes full access to all features in the tier you choose before you commit to a paid subscription.

Source
Cosign: Is signing alone enough?

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

ESET NOD32 Antivirus: What subscription contract lengths are available?

ESET offers subscription terms ranging from 1 to 10 years depending on the tier. Home Security Essential and Premium plans support 1-10 years, while Ultimate requires 5-10 years. Business plans also support multi-year terms.

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.

ESET NOD32 Antivirus: Will my renewal price change after the first year?

ESET states that the advertised price is valid for the first term only. They send advance notification via email before renewal price increases occur, allowing you to decide whether to continue.

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.

ESET NOD32 Antivirus: How many devices can I protect on a single subscription?

You can customize the number of protected devices from 1-10 on most plans. Premium and Ultimate tiers include VPN access that varies by device count: Essential/Premium include 3-5 VPN devices, while Ultimate covers 10-25 VPN devices depending on total plan size.

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.

ESET NOD32 Antivirus: Is there an extra charge to protect Android devices?

Android protection is available as an optional add-on at $5 per year per device, in addition to your main subscription cost.
