SaaS providers face unique challenges in AI security. You need controls that work for thousands of tenants with diverse requirements and budgets.

Multi-Tenancy Patterns

Shared Gateway, Tenant Policies

Single gateway instance with per-tenant policy configuration. Most cost-effective but requires careful isolation.

Dedicated Gateway Pools

Tenant groups share gateway pools. Balances cost and isolation.

Dedicated Per-Tenant

Each tenant gets dedicated resources. Highest isolation and cost.

Key Considerations

  • Tenant isolation (data, configuration, resources)
  • Cost allocation and chargeback
  • Self-service configuration
  • Audit logging per tenant
  • Performance fairness

Implementation Approach

Start with shared infrastructure and clear isolation boundaries. Add dedicated options as premium tiers. Invest heavily in monitoring and tenant-level observability.

The right design balances security, cost, and operational complexity for your specific customer base.
