Multi-Organization Hierarchy

Support a native multi-tenant model (org → sub-org → identity pools) so each business customer can have its own isolated user store and hierarchy within a single platform.

  • Model complex partner ecosystems with flexible org structures
  • Each customer manages its own users, roles, and policies
  • Isolated identity stores per organization

Delegated Administration

Empower partner organizations to manage their own users and groups while the provider retains central oversight.

  • Partner-appointed admins for user onboarding
  • Role assignment and access request handling
  • Reduced burden on internal IT teams

Self-Service SSO Integration

Enable partners to configure their own SSO connections without requiring central IT intervention.

  • Delegated SSO onboarding (SAML/OIDC setup)
  • Partner-controlled MFA settings
  • Eliminates SSO configuration bottlenecks

Partner Identity Federation

Each partner authenticates users through their own IdP—you trust the assertion without managing their credentials.

  • Partner-managed SSO with their Okta, Entra, or Ping instance
  • Brokered trust chains for multi-tier supplier networks
  • Just-in-time provisioning from federated assertions
Authorization

Fine-Grained Access Control

Enforce authorization policies at both global and organization-specific levels, with continuous risk assessment adapting decisions in real time.

Partner-Scoped Permissions

Define what each partner organization can access—down to specific APIs, data segments, and transaction types.

  • Per-partner API endpoint access controls
  • Data isolation rules scoped to organization or sub-org
  • Transaction-type restrictions (e.g., read-only vs. full write)

Hierarchical Policy Inheritance

Cascade policies from parent organizations to subsidiaries while allowing local overrides where permitted.

  • Global baseline policies inherited by all partner orgs
  • Sub-org policy overrides within delegated boundaries
  • Role inheritance across organization hierarchies

Partner Risk Scoring

Continuously assess partner session risk based on behavior, geography, and access patterns.

  • Per-partner risk thresholds and escalation rules
  • Geo-fencing and IP allowlisting per organization
  • Anomaly detection across partner access patterns

Contract-Based Entitlements

Enforce authorization based on partner agreements—feature tiers, usage quotas, and SLA boundaries.

  • Tier-based feature access (Basic, Pro, Enterprise)
  • Rate limiting and quota enforcement per partner
  • Time-bound access for trial or contract periods
Zero Trust & Cross-Domain Enforcement

Never Trust, Always Verify

Real-time policy decisions for every request across organizational boundaries and API integrations, with least-privilege access consistently enforced.

Zero Trust: Never Trust, Always Verify

Request
Verify Identity
Evaluate Risk
Check Policy
Grant Access

Continuous verification: Every request is authenticated, authorized, and risk-scored in real-time—regardless of network origin.

"Never Trust, Always Verify"

Every access request is continuously authenticated and authorized regardless of network origin.

Real-Time Transaction Enforcement

Make real-time policy decisions at the transaction level, inline with each API call or user action.

Least-Privilege Across Ecosystems

Each partner user is limited to only the resources and actions they absolutely need.

Cross-Domain Identity Federation

Support cross-domain trust without sacrificing security through federation and token exchange.

Adaptive Least Privilege

Combine risk analytics with Zero Trust to dynamically adjust privileges based on real-time context.

Partner Blast Radius Control

If one partner is compromised, contain the breach to their org's resources—no lateral movement to other partners or your core systems.

Trust Frameworks

Standards-Based Federation

Open standards and advanced OAuth/OIDC capabilities to integrate identities and enforce access across organizations. Enable fast, secure onboarding of new partners into your identity ecosystem.

Partner IdP Integration

Connect to each partner's existing identity provider—Okta, Entra ID, Ping, or custom SAML/OIDC—without directory duplication.

Cross-Domain Token Exchange

RFC 8693 Token Exchange enables partners to swap their IdP tokens for scoped SecureAuth tokens with partner-specific policies applied.

Multi-Party Delegation

On-Behalf-Of flows for supply chain scenarios where Partner A's user acts through Partner B's system to access your resources.

Self-Service Partner Onboarding

Partners configure their own SSO via guided federation setup—reducing IT overhead from weeks to hours per new organization.
