Air-Gapped Audit Bundle Exchange

Portable, self-contained evidence bundles for environments where network connectivity is unavailable, restricted, or untrusted. Complete cryptographic verification without external dependencies.

DoD/Gov Contractors

1. Target System

Disconnected, Denied, Intermittent, or Limited (DDIL) environments including classified networks, forward-deployed military systems, critical infrastructure with network isolation, and regulated environments requiring air-gapped audit trails.

2. Threat Model

Tampered evidence during network transit

Unauthorized modification of audit records

Replay attacks with stale evidence

Verifier substitution attacks

Chain discontinuity exploitation

3. Integration Points

Bundle Export

Programmatic export of evidence bundles as deterministic ZIP archives

Offline Verifier
