HashiCorp's Vault is a centralized secrets management system that provides encryption services gated by authentication and authorization methods to ensure secure, auditable, and restricted access to secrets. Organizations are advised to adopt a centralized system where all their secrets can be stored, organized, managed, and protected. The first step in resolving secret sprawl is to use Vault's secrets sync feature, which allows users to synchronize secrets from Vault to external secrets managers, ensuring that all secrets are up-to-date and reducing the risk of secret sprawl. Additionally, organizations should utilize secret scanning tools like HCP Vault Radar to detect and identify unmanaged secrets, and limit access to usable secrets by encrypting them. HashiCorp's Vault offers various platform options, including HCP Cloud Secrets, HCP Vault, Vault Enterprise, and HCP Vault Radar, each addressing different aspects of secrets management. Resolving secrets sprawl requires a comprehensive approach covering people, processes, and technology, and integrating Vault into a broader compliance strategy is crucial for achieving the best results.
