Editorial interest 82/100 Selection signal · not a rating of the site

Signeto describes a gateway where an AI agent requests approval for a sensitive action, a person signs on their phone, and the gateway issues a short-lived, narrowly scoped credential.

Landing page captured for the 2026-11-10 issue.

For: Teams letting AI agents touch production systems
Worth noticing: The page describes a SHA-256 hash-chained receipt ledger and offline verification through an open protocol.

Field notes

The examples distinguish several kinds of sensitive work: merging a production-repository pull request, running a database migration, and placing an order above a policy threshold. The page says the signed record includes the exact canonical bytes, decision, device, algorithm, and signature; it presents offline verification as possible without relying on the Signeto service.
