SaaS & Multi-Tenant Security Testing

Where SaaS applications fail#

Multi-tenant software depends on every data access enforcing organization context. A UI that hides another customer’s records is not a security control if the API accepts an arbitrary object ID.

Assessment priorities#

• Tenant isolation across read, edit, export and file-download workflows.
• Organization invitation, onboarding and membership transitions.
• Role-based functions, admin actions and privilege boundaries.
• API object and property authorization.
• Background jobs, webhooks and integration secrets.
• Billing and subscription state changes where relevant.

Result#

We provide evidence of validated boundary failures, exploit conditions and remediation guidance suitable for product engineers. Scope, environment, available roles and integrations are agreed before testing.
