J-SAS DIAM vs LoginRadius Customer Identity: Side-by-Side Comparison (2026)

J-SAS DIAM

Mid-market and enterprise supply chain teams managing hundreds of trading partners should evaluate J-SAS DIAM if identity sprawl across your vendor ecosystem is outpacing your governance capability. The platform handles 100,000+ user identities across 130,000+ organizations in a single tenant architecture, directly addressing NIST GV.SC supply chain risk management without forcing you into identity federation workarounds. Skip this if your priority is consumer-facing IAM or workforce SSO; J-SAS is built for B2B partner access, not employee directories.

LoginRadius Customer Identity

Mid-market and enterprise teams managing customer-facing authentication at scale should pick LoginRadius Customer Identity for its multi-tenant architecture, which lets you serve dozens of customer bases without spinning up separate infrastructure. The API-first design and cloud-native deployment mean integration into existing systems takes weeks, not months, and the platform handles NIST PR.AA access controls without forcing you into rigid role-based workflows. Skip this if you need deep workforce identity governance alongside customer identity; LoginRadius is purpose-built for external-facing authentication, not internal IAM.
