Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and mid-market teams tired of managing SSH keys across infrastructure will find real value in BastionZero OpenPubkey; it binds public keys directly to SSO identities, eliminating key rotation overhead and the audit nightmare of shared credentials. The hybrid deployment model and OpenID Connect integration mean you can bolt this onto existing identity stacks without ripping out authentication. Skip this if your environment demands air-gapped SSH access or you need identity management to also handle physical access controls; OpenPubkey is deliberately focused on logical asset authentication, not the broader PR.AA function.
