Ledger‑adjacent security
Protocols, custody flows, and notarization patterns for tokenized instruments.
SSH is an information security partner operating with minimal public surface area. We build systems where correctness is a property, not an assumption; where behavior is measured, not inferred.
We operate at two layers: the logic that should hold, and the behavior that actually occurs. Assurance emerges where they meet.
Specification before code. Determinism where possible. Evidence of correctness where it matters.
Runtime signals, anomaly maps, and event graphs to detect, explain, and respond.
Selective disclosure, cryptographic attestations, and compartmentalized access patterns.
Protocols, custody flows, and notarization patterns for tokenized instruments.
Modeling of critical paths; property‑based checks; specification‑guided reviews.
Signal extraction from runtime events; anomaly detection; controlled response playbooks.
Data‑minimizing architectures; attestations; compartmentalized access.
Interfaces for operations desks, auditors, and counterparties with clear trust boundaries.
Adversary mapping and stress paths centered on incentives and behavior.
A small public window into how we think: measure, don’t guess. Below is an illustrative Shannon‑entropy check over input text.
Redactions reflect our selective disclosure policy. Details available under NDA.
Briefings are offered to qualified organizations with a clear security mandate. We will not share sensitive methods outside appropriate agreements.
