Scalekit IdP-Initiated SSO vs Secrets Vault: Side-by-Side Comparison (2026)

Scalekit IdP-Initiated SSO

Mid-market and enterprise teams managing multiple identity providers without a unified user directory will move fastest with Scalekit IdP-Initiated SSO, since it converts IdP-initiated requests to SP-initiated flows automatically and requires zero user migration. The JWT-signed SAML assertions and webhook support for custom workflows address the PR.AA and PR.DS functions that most SSO deployments leave half-built. Skip this if your organization has already standardized on a single IdP or needs deep directory synchronization; Scalekit solves the conversion problem, not the identity source problem.

Secrets Vault

Startups and SMBs managing Web3 assets or handling sensitive customer data will find value in Secrets Vault's image-based passwordless authentication paired with post-quantum cryptography, which eliminates the attack surface of traditional passwords before quantum threats materialize. The zero-knowledge architecture means the vendor has no access to user data even under subpoena, and biometric verification happens on-device with zero storage of biometric templates. Organizations already deep in legacy identity infrastructure or those needing NIST compliance reporting across all five CSF functions should look elsewhere; Secrets Vault prioritizes authentication and data protection over the broader access control and governance workflows that larger enterprises demand.
