Authentication is very rarely a set and forget problem, especially for B2B applications. Your first authentication solution might have been a quick win, but as your application grows, so do the requirements around security, compliance, and user management.

PropelAuth BYO (Bring Your Own) is a self-hosted sidecar, written in Rust, that lets you add only the auth pieces you need, without replacing what already works.

• Own your data: Run in your cloud, keep full control.
• Adopt feature-by-feature: SSO, SCIM, Session Management, Passkeys, User Impersonation, and more. Each feature is independently adoptable and designed to slot into your existing flows.
• Straightforward integration: Opinionated client libraries with explicit, type-safe responses (including errors!).
• Operational clarity: Detailed & structured audit logs.
• Production performance: Built in Rust for speed and low resource usage.
• Happier customers: Tenant-level controls let you say yes to your customers security requests without code changes (e.g. IP allowlists, session rules).
