Three fundamental differences that no competitor can replicate overnight.
Others decrypt your key to plaintext when your app reads it. VaultProof splits it with Shamir — neither share alone reveals anything. The key only exists for ~100ms during a proxied call.
HashiCorp Vault requires infrastructure. AWS Secrets Manager requires SDK changes. VaultProof: change your base URL. Done.
The only secrets tool that understands vibe coding, AI agents, and LLM API keys. Auto-detects keys on provider pages, works with Cursor, Claude Code, Windsurf.
