Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Developers managing secrets across multiple cloud providers during local development should use Teller for its provider-agnostic approach; it pulls from AWS Secrets Manager, HashiCorp Vault, 1Password, and others without forcing a single vault standard. The 3,181 GitHub stars and free pricing mean adoption friction is genuinely low for teams testing secret rotation workflows before committing to a paid platform. Skip this if you need runtime secret injection in production containers or centralized audit logging; Teller is built for the laptop-to-staging workflow, not the control plane.
Enterprise teams managing secrets across IBM Cloud infrastructure will value IBM Cloud Secrets Manager for its single-tenant isolation model, which eliminates the blast radius risk of shared multi-tenant vaults. The HSM-backed PKI and dedicated instance architecture directly address NIST PR.AA access control requirements without forcing secrets into a shared environment. Skip this if you need a vendor-agnostic secrets engine; IBM Cloud Secrets Manager assumes you're already committed to IBM's ecosystem and integrates tightly with their toolchains and Key Protect service rather than standing alone.
Teller is a command-line secret management tool that integrates with various cloud providers and vaults to securely populate environment variables during development workflows.
