FAQ

Common questions about SaaS security testing.

Clear answers to help you understand our approach to protecting multi-tenant platforms.

SaaS security requires specific focus on multi-tenant isolation, where a vulnerability could expose data from thousands of customers simultaneously. We test tenant boundaries, shared resource access, organization hierarchies, and cross-tenant data leakage scenarios that don't exist in single-tenant applications. We also assess subscription logic, feature gating, and SSO integrations critical to SaaS platforms.
