SEC Cyber Disclosure Item 106 · OCC 2023-22 · DORA Art. 9 · NSM-10

Boards are about to be personally accountable for cryptographic decisions.

4 Qubits is the cryptographic system of record. Discover every crypto asset. Attest tamper-evidently with PQC signatures. Govern with two-person integrity. The only artifact that defends a director in deposition.

One family. Four products. One brand surface.

Each product is independently sellable, with its own SSO and pricing. Discover finds the crypto. Attest proves it. Govern decides on it. Vault ships it where the internet doesn't go.

PQC-native

ML-DSA-87 signing on every ledger entry (FIPS 204). ML-KEM key exchange (FIPS 203). SHA-256 + RFC 6962 hash chain. Crypto-agile by design.

Auditor-verifiable

Drag any 4Qubits attestation onto /verify, see the Merkle inclusion proof + ML-DSA-87 signature verification client-side. No login required.

Regulator-aligned

Maps to SEC Cyber Disclosure Rule, OCC 2023-22, OSFI B-13, DORA Art. 9, PCI v4.0 §12.3.3, NSM-10 / OMB M-23-02, NYDFS 500.17.

★ The killer demo

Drag any attestation onto /verify — see the Merkle proof + ML-DSA-87 signature ✅ in two seconds.

No login. No backend round-trip for verification math. Pure client-side cryptography against the published Merkle root. Hand it to an auditor or a chip-vendor exec and they understand instantly.
