CST VerdictShort answer
Startups and SMBs building customer-facing applications need FusionAuth Security because it handles multi-tenant identity infrastructure without the cost and operational overhead of enterprise platforms like Okta. The platform covers NIST PR.AA identity management and DE.CM continuous monitoring through breached password detection and webhook-based SIEM integration, letting you catch compromised credentials and anomalous access patterns without maintaining a separate threat intelligence feed. Skip this if you need mature identity governance and access reviews; FusionAuth prioritizes authentication and threat detection over the admin controls and audit workflows that large enterprises demand. Mid-market and enterprise teams managing third-party partner access at scale will get the most from Ory B2B IAM because its self-service onboarding cuts provisioning friction while passwordless authentication and granular least-privilege controls actually enforce what you configure. The API-first architecture and multi-region replication mean you're not fighting the platform to integrate it into your existing workflow or rebuild disaster recovery. Skip this if you need a directory-first identity platform that treats employee identities as the centerpiece; Ory is built for the messy reality of vendor, contractor, and partner ecosystems where you're managing access for accounts you don't fully control.
