Secure Secret Management with Vault

The problem with secrets in env vars

Secrets in .env files leak. They end up committed to git, copied to laptops, baked into images, shared in Slack. Rotation is impossible.

What Vault gives you

• A single source of truth for every credential
• Per-application access policies (your billing service cannot read auth secrets)
• Dynamic credentials: Vault issues short-lived per-connection database users instead of one shared password
• Audit log of every secret read
• One-line rotation: change the value, restart the consumer, done

How we deploy it

We stand up Vault behind your stack, configure AppRole authentication so your services authenticate without long-lived tokens, integrate the database secrets engine for dynamic Postgres credentials, and document the unseal and rotation procedures so the team can operate it confidently.
