Security testing for multi-tenant SaaS applications.
Multi-tenant SaaS lives and dies by tenant isolation. A single broken authorization check can expose one customer's data to another. Continuous, autonomous testing across roles and tenants is the most reliable way to keep isolation intact as you ship.
Tenant isolation is everything
Cross-tenant IDOR/BOLA is the defining SaaS risk. Testing must replay one tenant's requests against another's objects across every role and endpoint.
Fast release cadence
SaaS teams deploy constantly. Point-in-time pentests miss most of what ships; continuous testing on every deploy closes the gap.
Customer trust and audits
Enterprise buyers demand SOC 2 and evidence of testing. Reproducible findings streamline security reviews and sales.
Key risks to test
Compliance
Evidence-backed findings support SOC 2 and ISO 27001 review that enterprise buyers expect.
FAQ
How do you test multi-tenant SaaS for data isolation?
Provision accounts in separate tenants and systematically replay each tenant's requests against the other's objects and functions across every role and HTTP method, confirming the server enforces isolation.
Impactr finds and proves whether flaws like this are actually reachable in your own web apps and APIs, with a reproducible exploit as evidence.
