Hackers accessed data from 200+ Salesforce customers using stolen OAuth tokens from a Gainsight breach (November 21, 2025).
Zsub fixes this.
Zsub has no IdP, no third-party tokens, no aggregated credentials.
Authentication is self-sovereign, direct P2P via hierarchical keys and trust chains you control.
No intermediaries hold keys that can cascade breaches across users or services.
Supply-chain attacks can't propagate because there's no central auth plane to compromise.
Actually zero trust, just like Bitcoin.
Not your keys, not your network.
