The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Google Cloud Secret Manager
Google Cloud Secret Manager — The right default for GCP-first teams because it is a managed, versioned secrets service with rollback, recovery, permissions, and auditability built into the Google Cloud control plane.
ChatGPT
HashiCorp Vault
HCP Vault Dedicated (HashiCorp Vault) — My strongest general recommendation for larger multi-cloud/hybrid teams because it combines mature policy/audit controls with static secrets, PKI, and on-demand, revocable credentials without making you operate the Vault control plane yourself.
