Zero-trust architecture with vault containers: a practical guide

I wrote up a guide on implementing zero-trust patterns with 0nMCP vault containers. **Principle 1: Never trust, always verify** Every credential access goes through vault_unseal → verify_fingerprint → decrypt. The hardware fingerprint binding means stolen vault files are useless on other machines. **Principle 2: Least privilege** Vault containers have 7 layers. Give each team member access to only the layers they need. Developer gets workflows+env_vars. DevOps gets credentials+mcp_configs. Finance gets nothing except audit_trail. **Principle 3: Audit everything** The audit_trail layer records every access, modification, and transfer. Cryptographic receipts via the Seal of Truth. **Principle 4: Rotate regularly** Engine verify (`0nmcp engine verify`) tests all API keys and flags expired ones. Run it weekly. Questions welcome. Security is everyone's responsibility. --- *Discuss more at [0n MCP](https://www.0nmcp.com) — the hub for [MCP server integration](https://www.0nmcp.com).*
