B2B CIAM
Enterprise Ready.
Selling B2B SaaS upmarket means clearing the same checklist every time: SSO, SCIM, audit logs, roles, organizations, security policy, and residency. This is the builder's guide to shipping each pillar, and the buyer's view of which CIAM platforms already cover them.
Builder playbooks
One playbook per pillar: why enterprises demand it, how to ship it, the standards, the pitfalls, and a build checklist.
- Enterprise SSO
Ship enterprise SSO (SAML and OIDC)
SSO is the first thing an enterprise buyer asks for: let their employees sign in with the company IdP. Support both SAML 2.0 and OIDC, make connection setup self-serve, and route users to the right connection by verified email domain. Manual, per-customer SSO does not scale, self-serve is the unlock.
- SCIM / directory sync
Ship SCIM and directory sync
SCIM keeps your user directory in sync with the customer's IdP: users are provisioned, updated, and, most importantly, deprovisioned automatically. Enterprises treat automated offboarding as a security control, so SCIM often follows SSO as the next hard requirement. Support SCIM 2.0 per organization, and handle the messy per-IdP quirks.
- Audit logs
Ship audit logs and log streaming
Enterprise security reviews expect a tamper-evident, per-tenant audit log of authentication and administrative events, and increasingly the ability to stream it into their own SIEM. Log the right events with enough context, scope them to the tenant, and offer export or streaming.
- RBAC & roles
Ship RBAC and custom roles
Enterprise customers expect to manage access with roles scoped to their organization, and often to define custom roles rather than accept your fixed set. Start with clean org-scoped RBAC and least privilege, then plan a path to fine-grained authorization as resource-level access needs grow.
- Organizations
Ship organizations and delegated admin
The Organization is the backbone of enterprise readiness: it is the boundary that owns SSO, SCIM, roles, and audit, and it lets customers administer their own users through delegated admin. Model it first, before you build the enterprise features that hang off it.
- Session & security policy
Ship session and security policy controls
Enterprises want to enforce their own security posture inside your app: mandatory MFA, session lifetime and idle timeout, forced logout, and adaptive step-up on risky actions, all configurable per organization. Expose these as tenant-level policy, not global defaults.
- Data residency & compliance
Ship data residency and compliance posture
Enterprise and regulated buyers ask where identity data lives and which certifications you hold. Offer regional data residency, sign a DPA with SCCs where relevant, and back it with the certifications enterprise procurement expects (SOC 2, ISO 27001, and industry frameworks as needed).
