VaultProof vs the rest
VaultProof keeps the raw provider key out of your application runtime. It is reconstructed only inside the proxy for the upstream request, then cleared from memory.

What makes VaultProof different
Three architectural differences to evaluate against your runtime and custody requirements.
Your key is only assembled briefly during API calls
Others decrypt your key to plaintext when your app reads it. VaultProof splits it into two encrypted shares — neither share alone reveals anything. The key only exists briefly in memory during a proxied call.
One line, not one migration
HashiCorp Vault requires infrastructure. AWS Secrets Manager requires SDK changes. VaultProof: change your base URL. Done.
Built for AI developers
