SaaS Penetration Testing

SaaS platforms face a unique threat landscape where a single vulnerability can expose every customer's data. Our SaaS penetration testing methodology is purpose-built for multi-tenant architectures, targeting the vulnerabilities that matter most: tenant-to-tenant data leakage, privilege escalation between tenants, and administrative console compromise. Multi-tenant isolation is our primary focus. We systematically test every data access path to verify that Tenant A cannot access Tenant B's data - through direct object references, API parameter manipulation, cached data leakage, shared resource exploitation, and database query manipulation. We test both logical isolation (application-level) and infrastructure isolation (database, storage, compute) depending on your architecture. Beyond isolation, we assess your entire SaaS attack surface: API security across all endpoints (REST, GraphQL, WebSocket), authentication and SSO integration (SAML, OAuth, OIDC), role-based access control within and across tenants, subscription and billing logic manipulation, webhook security, and data export/import functionality. We also evaluate your CI/CD pipeline security - testing for secrets exposure in build logs, artifact tampering, and deployment pipeline compromise that could affect all tenants simultaneously. Cloud infrastructure misconfigurations (IAM, storage buckets, network segmentation) are assessed for multi-tenant impact. Our testing is designed for production-safe execution. We work closely with your engineering team to define safe testing boundaries, use dedicated test tenants, and coordinate any potentially disruptive tests. Critical vulnerabilities are reported immediately - we never hold urgent findings for the final report.
