Three fundamental differences that no competitor can replicate overnight.
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.
HashiCorp Vault requires infrastructure. AWS Secrets Manager requires SDK changes. VaultProof: change your base URL. Done.
